It can be combined with other members of the DIGIT3000 IC family (such as DDP 331x) and/or it can be used with 3rd-party products. - high-quality soft mixer controlled by Fast Blank The main features of the VPC 323xD are - 15 predefined PIP display configurations and expert mode (fully programmable) - high-performance adaptive 4H comb filter Y/C separator with adjustable vertical peaking - control interface for external field memory 1 - , or - PIP processing for four picture sizes ( 1--4- , 1--9-, ----16 1 --of normal size) with 8-bit resolution 36 - I2C-bus interface - multi-standard color decoder PAL/NTSC/SECAM including all substandards - one 20.25-MHz crystal, few external components - four CVBS, one S-VHS input, one CVBS output - 80-pin PQFP package - two RGB/YCrCb component inputs, one Fast Blank (FB) input 1.1.

VPC Applications Fig. 1-2 depicts several VPC applications. Since the VPC functions as a video front-end, it must be complemented with additional functionality to form a complete TV set. The DDP 331x contains the video back-end with video postprocessing (contrast, peaking, CTI,...), H/V-deflection, RGB insertion (SCART, Text, PIP,...) and tube control (cutoff, white-drive, beam current limiter). It generates a beam scan velocity modulation output from the digital YCrCb and RGB signals. Note, that this signal is not generated from the external analog RGB inputs. external sources, such as MPEG-2 set-top boxes in transparent (4:2:2) quality. Furthermore, it transforms RGB/Fast Blank signals to the common digital video bus and makes those signals available for 100-Hz upconversion or double-scan processing. In some European countries (Italy), this feature is mandatory. SRC (e. g. SDA 94xx from Micronas) indicates memory based image processing, such as scan rate conversion, vertical processing (Zoom), or PAL+ reconstruction. The VPC supports memory-based applications through line-locked clocks, syncs, and data. Additionally, the VPC 323xD provides a 656-output interface and FIFO control signals. Examples: The component interface of the VPC 323xD provides a high-quality analog RGB interface with character insertion capability.

Functional Description 2.1.3. Automatic Gain Control 2.1. Analog Video Front-End A digitally working automatic gain control adjusts the magnitude of the selected baseband by +6/-4.5 dB in 64 logarithmic steps to the optimal range of the ADC. The gain of the video input stage including the ADC is 213 steps/V with the AGC set to 0 dB. This block provides the analog interfaces to all video inputs and mainly carries out analog-to-digital conversion for the following digital video processing. A block diagram is given in Fig. 2-1. Most of the functional blocks in the front-end are digitally controlled (clamping, AGC, and clock-DCO). The control loops are closed by the Fast Processor (`FP') embedded in the decoder. 2.1.1. Input Selector Up to five analog inputs can be connected. Four inputs are for composite video or S-VHS luma signal. These inputs are clamped to the sync back porch and are amplified by a variable gain amplifier. One input is for connection of S-VHS carrier chrominance signal. This input is internally biased and has a fixed gain amplifier. A second S-VHS chroma signal can be connected to video-input VIN1. 2.1.4. Analog-to-Digital Converters Two ADCs are provided to digitize the input signals. Each converter runs with 20.25 MHz and has 8 bit resolution. An integrated bandgap circuit generates the required reference voltages for the converters. The two ADCs are of a 2-stage subranging type. 2.1.5. Digitally Controlled Clock Oscillator The clock generation is also a part of the analog front end. The crystal oscillator is controlled digitally by the control processor; the clock frequency can be adjusted within 150 ppm. 2.1.6. Analog Video Output 2.1.2. Clamping The composite video input signals are AC coupled to the IC. The clamping voltage is stored on the coupling capacitors and is generated by digitally controlled current sources. The clamping level is the back porch of the video signal. S-VHS chroma is also AC coupled. The input pin is internally biased to the center of the ADC input range. Analog Video Output CVBS/Y CVBS/Y CVBS/Y/C C AGC +6/-4.5 dB VIN4 clamp VIN3 VIN2 VIN1 input mux CVBS/Y The input signal of the Luma ADC is available at the analog video output pin. The signal at this pin must be buffered by a source follower. The output voltage is 2 V, thus the signal can be used to drive a 75 line. The magnitude is adjusted with an AGC in 8 steps together with the main AGC.

Adaptive Comb Filter The 4H adaptive comb filter is used for high-quality luminance/chrominance separation for PAL or NTSC composite video signals. The comb filter improves the luminance resolution (bandwidth) and reduces interferences like cross-luminance and cross-color. The adaptive algorithm eliminates most of the mentioned errors without introducing new artifacts or noise. A block diagram of the comb filter is shown in Fig. 2-2. The filter uses four line delays to process the information of three video lines. To have a fixed phase relationship of the color subcarrier in the three channels, the system clock (20.25 MHz) is fractionally locked to the color subcarrier. This allows the processing of all color standards and substandards using a single crystal frequency. The CVBS signal in the three channels is filtered at the subcarrier frequency by a set of bandpass/notch filters. The output of the three channels is used by the adaption logic to select the weighting that is used to reconstruct the luminance/chrominance signal from the 4 bandpass/notch filter signals. By using soft mixing of the 4 signals switching artifacts of the adaption algorithm are completely suppressed. The comb filter uses the middle line as reference, therefore, the comb filter delay is two lines. If the comb filter is switched off, the delay lines are used to pass the luma/chroma signals from the A/D converters to the luma/chroma outputs. Thus, the processing delay is always two lines. In order to obtain the best-suited picture quality, the user has the possibility to influence the behavior of the adaption algorithm going from moderate combing to strong combing. Therefore, the following three parameters may be adjusted: - VDG (vertical difference gain) - DDR (diagonal dot reducer) VDG typically determines the comb filter behavior on vertical edges. As VDG increases, the comb strength, e. g. the amount of hanging dots, decreases. After selecting the combfilter performance in horizontal and vertical direction, the diagonal picture performance may further be optimized by adjusting DDR. As DDR increases, the dot crawl on diagonal colored edges is reduced. To enhance the vertical resolution of the picture, the VPC provides a vertical peaking circuitry. The filter gain is adjustable between 0 - +6 dB and a coring filter suppresses small amplitudes to reduce noise artifacts. In relation to the comb filter, this vertical peaking widely contributes to an optimal two-dimensional resolution homogeneity. 2.3. Color Decoder In this block, the standard luma/chroma separation and multi-standard color demodulation is carried out. The color demodulation uses an asynchronous clock, thus allowing a unified architecture for all color standards. A block diagram of the color decoder is shown in Fig. 2-4. The luma as well as the chroma processing, is shown here. The color decoder also provides several special modes, e.g. wide band chroma format which is intended for S-VHS wide bandwidth chroma. Also, filter settings are available for processing a PAL+ helper signal. If the adaptive comb filter is used for luma chroma separation, the color decoder uses the S-VHS mode processing. The output of the color decoder is YCrC b in a 4:2:2 format. Bandpass Filter CVBS Input 2H Delay Line 2H Delay Line Chroma Input Bandpass/ Notch Filter Bandpass Filter Luma / Chroma Mixers Adaption Logic - HDG (horizontal difference gain) HDG typically defines the comb strength on horizontal edges. It determines the amount of the remaining cross-luminance and the sharpness on edges respectively. As HDG increases, the comb strength, e. g. cross luminance reduction and sharpness, increases. Luma Output Chroma Output Fig. 2-2: Block diagram of the adaptive comb filter (PAL mode) Micronas 9 VPC 323xD PRELIMINARY DATA SHEET 2.3.1. IF-Compensation 2.3.2. Demodulator With off-air or mistuned reception, any attenuation at higher frequencies or asymmetry around the color subcarrier is compensated. Four different settings of the IF-compensation are possible (see Fig. 2-3): - 10 dB/MHz The entire signal (which might still contain luma) is quadrature-mixed to the baseband. The mixing frequency is equal to the subcarrier for PAL and NTSC, thus achieving the chroma demodulation. For SECAM, the mixing frequency is 4.286 MHz giving the quadrature baseband components of the FM modulated chroma. After the mixer, a lowpass filter selects the chroma components; a downsampling stage converts the color difference signals to a multiplexed half rate data stream. The last setting gives a very large boost to high frequencies. It is provided for SECAM signals that are decoded using a SAW filter specified originally for the PAL standard. The subcarrier frequency in the demodulator is generated by direct digital synthesis; therefore, substandards such as PAL 3.58 or NTSC 4.43 can also be demodulated. - flat (no compensation) - 6 dB/octave - 12 dB/octave 2.3.3. Chrominance Filter dB The demodulation is followed by a lowpass filter for the color difference signals for PAL/NTSC. SECAM requires a modified lowpass function with bell filter characteristic. At the output of the lowpass filter, all luma information is eliminated. The lowpass filters are calculated in time multiplex for the two color signals. Three bandwidth settings (narrow, normal, broad) are available for each standard (see Fig. 2-5). For PAL/NTSC, a wide band chroma filter can be selected. This filter is intended for high bandwidth chroma signals, e.g. a nonstandard wide bandwidth S-VHS signal.

Color Killer Operation PAL/NTSC MHz dB The color killer uses the burst-phase /burst-frequency measurement to identify a PAL/NTSC or SECAM color signal. For PAL/NTSC, the color is switched off (killed) as long as the color subcarrier PLL is not locked. For SECAM, the killer is controlled by the toggle of the burst frequency. The burst amplitude measurement is used to switch off the color if the burst amplitude is below a programmable threshold. Thus, color will be killed for very noisy signals. The color amplitude killer has a programmable hysteresis. 2.3.7. Automatic Standard Recognition SECAM MHz Fig. 2-5: Frequency response of chroma filters The burst-frequency measurement is also used for automatic standard recognition (together with the status of horizontal and vertical locking) thus allowing a completely independent search of the line and color standard of the input signal. The following standards can be distinguished: 2.3.4. Frequency Demodulator PAL B,G,H,I; NTSC M; SECAM; NTSC 44; PAL M; PAL N; PAL 60 The frequency demodulator for demodulating the SECAM signal is implemented as a CORDIC-structure. It calculates the phase and magnitude of the quadrature components by coordinate rotation. For a preselection of allowed standards, the recognition can be enabled/disabled via I2C bus for each standard separately. The phase output of the CORDIC processor is differentiated to obtain the demodulated frequency. After the deemphasis filter, the Dr and Db signals are scaled to standard C rCb amplitudes and fed to the crossover-switch. 2.3.5. Burst Detection / Saturation Control In the PAL/NTSC system the burst is the reference for the color signal. The phase and magnitude outputs of the CORDIC are gated with the color key and used for controlling the phase-locked loop (APC) of the demodulator and the automatic color control (ACC) in PAL/ NTSC. If at least one standard is enabled, the VPC 323xD checks regularly the horizontal and vertical locking of the input signal and the state of the color killer. If an error exists for several adjacent fields a new standard search is started. Depending on the measured line number and burst frequency the current standard is selected. For error handling, the recognition algorithm delivers the following status information: - search active (busy) - search terminated, but failed - found standard is disabled - vertical standard invalid The ACC has a control range of +30 ... -6 dB. - no color found Color saturation is adjustable independently of the color standard. In PAL/NTSC it is used as reference for the ACC. In SECAM the necessary gains are calculated automatically. For SECAM decoding, the frequency of the burst is measured. Thus, the current chroma carrier frequency can be identified and is used to control the SECAM processing. The burst measurements also control the Micronas 11 VPC 323xD PRELIMINARY DATA SHEET 2.3.8.

In the NTSC compensated mode, Fig. 2-6 c), the color signal is averaged for two adjacent lines. Thus, cross-color distortion and chroma noise is reduced. In the NTSC 1-H comb filter mode, Fig. 2-6 d), the delay line is in the composite signal path, thus allowing reduction of cross-color components, as well as cross-luminance. The loss of vertical resolution in the luminance channel is compensated by adding the vertical detail signal with removed color information.

Luminance Notch Filter 2.4. Component Interface Processor CIP If a composite video signal is applied, the color information is suppressed by a programmable notch filter. The position of the filter center frequency depends on the subcarrier frequency for PAL/NTSC. For SECAM, the notch is directly controlled by the chroma carrier frequency. This considerably reduces the cross-luminance. The frequency responses for all three systems are shown in Fig. 2-9. This block (see Fig. 2-10) contains all the necessary circuitry dedicated to external analog components (YCrCb_cip) such as RGB or YCrCb signals from DVD players, or other RGB sources with Fast Blank for real time insertion on the main picture (YCrCb_main). 10 2.4.1. Component Analog Front-End VPC 323xD provides two analog RGB/YCrCb input ports, one with Fast Blank capability and one without. dB 0 Analog component signals contain high-frequency components (e. g. OSD) and/or high-frequency clock residues. Thus, it is recommended to implement analog anti-alias low-pass filters on each input, including FB (e. g. -3 dB at 5...6 MHz). While all signals are coupled by 220 nF clamping capacitors, the Fast Blank input requires DC coupling. -10 -20 -30 -40 0 2 4 6 8 10 MHz The selected signal channel is further converted into a digital form by three high-quality ADCs running at 20.25 MHz with a resolution of 8 bit.

In component mode, the sync signal has to be fed to this input accordingly. -10 -20 2.4.2. Matrix -30 -40 0 2 4 6 8 10 MHz SECAM notch filter Fig. 2-9: Frequency responses of the luma notch filter for PAL, NTSC, SECAM 2.3.10. Skew Filtering The RGB signals are converted to the YCrCb format by a matrix operation: Y = 0.299R + 0.587G + 0.114B (R-Y)= 0.701R - 0.587G - 0.114B (B-Y)=-0.299R - 0.587G + 0.886B In case of YCrCb input the matrix is bypassed. The system clock is free-running and not locked to the TV line frequency. Therefore, the ADC sampling pattern is not orthogonal. The decoded YCrCb signals are converted to an orthogonal sampling raster by the skew filters, which are part of the scaler block. 2.4.3. Component YCrCb Control The skew filters are controlled by a skew parameter and allow the application of a group delay to the input signals without introducing waveform or frequency response distortion. - -128 brightness 127 The amount of phase shift of this filter is controlled by the horizontal PLL1. The accuracy of the filters is 1/32 clocks for luminance and 1/4 clocks for chroma. Thus the 4:2:2 YCrCb data is in an orthogonal pixel format even in the case of nonstandard input signals such as VCR. Micronas The VPC 323xD supports the following picture adjustment parameters on the component signal: - 0 contrast 63/32 - 0 saturation Cr 63/32 - 0 saturation Cb 63/32 - -20 tint 20 degrees 13 VPC 323xD PRELIMINARY DATA SHEET Table 2-1 shows the settings to achieve exact level matching between YCrCb_cip and YCrCb_main channel. The factor k is clamped to 0 or 64, hence selecting YCrCb_main or the component input YCrCb_cip (see Table 2-2). Table 2-1: Standard picture settings 2.4.4.2. Static Mixer Mode input format contrast brightness satCr satCb RGB 27 68 29 23 YCrCb 27 68 40 40 The signal YCrCb_main and the component signal YCrCb_cip may also be statically mixed. In this environment, k is manually controlled via I2C registers FBGAIN and FBOFFS according to the following expression: k = FBGAIN*(31-FBOFFS) + 32 Note: R, G, B, Cr, Cb, = 0.7 Vpp, Y(+ sync) 1 Vpp 2.4.4. Softmixer All the necessary limitation and rounding operation are built-in to fit the range: 0 k 64. After an automatic delay matching, the component signals and the upsampled main video signal are gathered onto a unique YCrCb channel by means of a versatile 4:4:4 softmixer (see also Fig. 2-10). In the static mixer mode as well as in the previously mentioned static switch mode (see Table 2-2), the softmixer operates independently of the analog Fast Blank input. The softmixer circuit consists of a Fast Blank (FB) processing block supplying a mixing factor k (0...64) to a high quality signal mixer achieving the output function: 2.4.4.3. Dynamic Mixer Mode YCrCb_mix=( k*YCrCb_main+ (64-k)*YCrCb_cip )/64 In the dynamic mixer mode, the mixer is controlled by the Fast Blank signal. The VPC 323xD provides a linear mixing coefficient The softmixer supports several basic modes that are selected via I2C bus (see Table 2-2). k=kl = FBGAIN*(FB-FBOFFS) + 32 (FB is the digitized Fast Blank), and a non-linear mixing coefficient knl=F(kl), which results from a further non-linear processing of kl. 2.4.4.1. Static Switch Mode In its simplest and most common application the softmixer is used as a static switch between YCrCb_main and YCrCb_cip. This is for instance the adequate way to handle a DVD component signal. While the linear mixing coefficient is used to insert a full-screen video signal, the non-linear coefficient is well-suited to insert Fast Blank related signals like text. The non-linear mixing reduces disturbing effects like over/undershoots at critical Fast Blank edges. mixer YCrCb_main VIDEO Y/C processing YCrCb_mix YCrCb_cip RGB/YCrCb Component Processing Fig. 2-10: Block diagram of the component mixer 14 Micronas VPC 323xD PRELIMINARY DATA SHEET Table 2-2: CIP softmixer modes analog fast blank input I2C SELLIN RGB DLY FBCLP FB MODE CIP mode Force YCrCb main 0 Force RGB/ YCrCb 0 Static Mixer 0 0 1 01 FB Linear 0 0 0 01 FB nonLinear 1 1 0 01 0 x 11 reading I2C register <27> <27>FBLSTAT 0 1 1 0 0 <27>FBLRISE 0 1 0 0 0 <27>FBLFALL 0 0 0 1 0 <27>FBLHIGH 0 1 1 1 0 Fig. 2-11: Fast Blank Monitor 0 x x0 2.4.5. 4:4:4 to 4:2:2 Downsampling After the mixer, the 4:4:4 YCrCb_mix data stream is downsampled to the 4:2:2 format. For this sake, a chroma lowpass filter is provided to eliminate high-frequency components above 5-6 Mhz which may typically be present on inserted high resolution RGB/ YCrCb sources. In case of main video processing (loop-through) only, it is recommended to bypass this filter by using the I2C bit CIPCFBY. An additional monitoring bit is also provided for the RGB/YCrCb signal; it indicates whether the ADCs inputs are clipped or not. In case of clipping conditions (1Vpp RGB input for example) the ADC range can be extended by 3db by using the XAR bit. - CLIPD: set by RGB/YC rCb input clip, reset by register read 2.5. Horizontal Scaler The 4:2:2 YCrCb signal from the mixer output is processed by the horizontal scaler. It contains a lowpass filter, a prescaler, a scaling engine and a peaking filter. The scaler block allows a linear or nonlinear horizontal scaling of the input signal in the range of 1/32 to 4. Nonlinear scaling, also called "panorama vision", provides a geometrical distortion of the input picture. It is used to fit a picture with 4:3 format on a 16:9 screen by stretching the picture geometry at the borders. Also, the inverse effect - called water glass - can be produced by the scaler. A summary of scaler modes is given in Table 2-3. 2.5.1. Horizontal Lowpass-filter 2.4.6. Fast Blank and Signal Monitoring The analog Fast Blank state is monitored by means of four I2C readable bits. These bits may be used by the TV controller for SCART signal ident: The luma filter block applies anti-aliasing lowpass filters. The cutoff frequencies are selectable and have to be adapted to the horizontal scaling ratio. - FBHIGH: set by FB high, reset by register read at FB low - FBSTAT: FB status at register read - FBRISE: set by FB rising edge, reset by register read - FBFALL: set by FB falling edge, reset by register read Micronas 15 VPC 323xD PRELIMINARY DATA SHEET dB Table 2-3: Scaler modes 10 0 Mode -10 -20 Scale Factor Compression 4:3 16:9 0.75 linear 4:3 source displayed on a 16:9 tube, with side panels Panorama 4:3 16:9 nonlinear compr 4:3 source displayed on a 16:9 tube, Borders distorted Zoom 4:3 4:3 1.33 linear Letterbox source (PAL+) displayed on a 4:3 tube, vertical overscan with cropping of side panels Water glass 16:9 4:3 nonlinear zoom Letterbox source (PAL+) displayed on a 4:3 tube, vertical overscan, borders distorted, no cropping 20.25 13.5 MHz 0.66 sample rate conversion to line-locked clock -30 -40 -50 2 4 6 8 Description 10 MHz dB 10 0 -10 -20 -30 -40 -50 1 2 3 4 5 MHz Fig. 2-12: YCrCb downsampling lowpass-filter 2.5.2. Horizontal Prescaler To achieve a horizontal compression ratio between 1/4 and 1/32 (e. g. for double window or PIP operation) a linear downsampler resamples the input signal by 1 (=no presampling), 2, 4, and 8. 2.5.4. Horizontal Peaking-filter The horizontal scaler block offers an extra peaking filter for sharpness control. The center frequency of the peaking filter automatically adopts to the horizontal scaling ratio. Three center frequencies are selectable (see Fig. 2-13: ) - center at sampling rate / 2 - center at sampling rate / 4 - center at sampling rate / 6 2.5.3. Horizontal Scaling Engine The scaler contains a programmable decimation filter, a 1-H FIFO memory, and a programmable interpolation filter. The scaler input filter is also used for pixel skew correction, see 2.3.10. The decimator/interpolator structure allows optimal use of the FIFO memory. It allows a linear or nonlinear horizontal scaling of the input video signal in the range of 0.25 to 4. The controlling of the scaler is done by the internal Fast Processor. 16 The filter gain is adjustable between 0 - +10 dB and a coring filter suppresses small amplitudes to reduce noise artifacts.

Therefore the subtitles are visible on the screen. To suppress the subtitles, the vertical zoom coefficient is calculated by selecting the larger number of black lines only. Dark video scenes with a low contrast level compared to the letterbox area are indicated by the BLKPIC bit. LLC1/MHz Fig. 2-13: Peaking characteristics 2.6. Vertical Scaler For PIP operation, the vertical scaler compresses the incoming 4:2:2 YCrCb active video signal in vertical direction. It supports a vertical compression ratio of 1(= no compression), 2, 3, 4 and 6. In case of a vertical compression of 2, 4 and 6, the filter performs the PAL compensation automatically and the standard PAL delay line should be bypassed (see 2.3.8.). 2.7. Contrast and Brightness The VPC 323xD provides a selectable contrast and brightness adjustment for the luma samples. The control ranges are: - 0 contrast 63/32 - -128 brightness 127 Note: for ITU-R luma output code levels (16 ... 240), contrast has to be set to 48 and brightness has to be set to 16! 2.8. Blackline Detector In case of a letterbox format input video, e.g. Cinemascope, PAL+ etc., black areas at the upper and lower part of the picture are visible. It is suitable to remove or reduce these areas by a vertical zoom and/or shift operation. The VPC 323xD supports this feature by a letterbox detector. The circuitry detects black video lines by measuring the signal amplitude during active video. For every field the number of black lines at the upper and lower part of the picture are measured, compared to the previous measurement and the minima are stored in the I2C register BLKLIN. To adjust the picture Micronas 2.9. Control and Data Output Signals The VPC 323xD supports two output modes: In DIGIT3000 mode, the output interfaces run at the main system clock, in line-locked mode, the VPC generates an asynchronous line-locked clock that is used for the output interfaces. The VPC delivers either a YCrC b 4:2:2 or a YCrC b 4:1:1 data stream, each with separate sync information. In case of YCrCb 4:2:2 format, the VPC 323xD also provides an interface with embedded syncs according to ITU-R656. 2.9.1. Line-Locked Clock Generation An on-chip rate multiplier is used to synthesize any desired output clock frequency of 13.5/16/18 MHz. A double clock frequency output is available to support 100 Hz systems. The synthesizer is controlled by the embedded RISC controller, which also controls all front-end loops (clamp, AGC, PLL1, etc.). This allows the generation of a line-locked output clock regardless of the system clock (20.25 MHz) which is used for comb filter operation and color decoding. The control of scaling and output clock frequency is kept independent to allow aspect ratio conversion combined with sample rate conversion. The line-locked clock circuity generates control signals, e.g. horizontal/vertical sync, active video output, it is also the interface from the internal (20.25 MHz) clock to the external line-locked clock system. If a line-locked clock is not required, i.e. in the DIGIT3000 mode, the system runs at the 20.25 MHz main clock. The horizontal timing reference in this mode is provided by the front-sync signal. In this case, the line-locked clock block and all interfaces run from the 20.25 MHz main clock. The synchronization signals from the line-locked clock block are still available, but for every line the internal counters are reset with the main-sync signal. A double clock signal is not available in DIGIT3000 mode. 17 VPC 323xD PRELIMINARY DATA SHEET 2.9.2. Sync Signals 2.9.5. Line-Locked 4:1:1 Output Format The front end will provide a number of sync/control signals which are output with the output clock. The sync signals are generated in the line-locked clock block. The orthogonal 4:1:1 output format is compatible to the industry standard. The YCrCb samples are skew-corrected and interpolated to an orthogonal sampling raster (see Table 2-5). - Href: horizontal sync - AVO: active video out (programmable) - HC: horizontal clamp (programmable) - Vref: vertical sync - INTLC: interlace Table 2-5: 4:1:1 Orthogonal output format Luma Chroma Y1 Y2 Y3 Y4 C3 , C7 Cb17 Cb15 Cb13 Cb11 All horizontal signals are not qualified with field information, i.e. the signals are present on all lines.

ITU-R 656 Output Format 2.9.3. DIGIT3000 Output Format The picture bus format between all DIGIT3000 ICs is 4:2:2 YCrCb with 20.25 MHz samples/s. Only active video is transferred, synchronized by the system main sync signal (MSY) which indicates the start of valid data for each scan line and which initializes the color multiplex. The video data is orthogonally sampled YCrCb, the output format is given in Table 2-4. The number of active samples per line is 1080 for all standards (525 and 625). The output can be switched to 4:1:1 mode with the output format according to Table 2-5. Via the MSY line, serial data is transferred which contains information about the main picture such as current line number, odd/even field etc.). It is generated by the deflection circuitry and represents the orthogonal timebase for the entire system. Table 2-4: Orthogonal 4:2:2 output format Luma Y1 Y2 Y3 Y4 Chroma Cb1 C r1 Cb3 Cr3 2.9.4. Line-Locked 4:2:2 Output Format This interface uses a YC rCb 4:2:2 data stream at a line-locked clock of 13.5 MHz. Luminance and chrominance information is multiplexed to 27 MHz in the following order: Cb1, Y1, Cr1, Y2, ... Timing reference codes are inserted into the data stream at the beginning and the end of each video line: - a `Start of active video'-Header (SAV) is inserted before the first active video sample - a `End of active video'-code (EAV) is inserted after the last active video sample. The incoming videostream is limited to a range of 1...254 since the data words 0 and 255 are used for identification of the reference headers. Both headers contain information about the field type and field blanking. The data words occurring during the horizontal blanking interval between EAV and SAV are filled with 0x10 for luminance and 0x80 for chrominance information. Table 2-6 shows the format of the SAV and EAV header. For activation of this output format, the following selections must be assured: - 13.5 MHz line locked clock - double-clock mode enabled In line-locked mode, the VPC 323xD provides the industry standard pixel stream for YCrC b data. The difference to DIGIT3000 native mode is only the number of active samples, which of course, depends on the chosen scaling factor. Thus, Table 2-4 is valid for both 4:2:2 modes. 18 - ITU-R656-mode enabled - binary offset for Cr/Cb data Note that the following changes and extensions to the ITU-R656 standard have been included to support horizontal and vertical scaling: Micronas VPC 323xD PRELIMINARY DATA SHEET Table 2-6: Coding of the SAV/EAV-header - Both the length and the number of active video lines varies with the selected window parameters. For compliance with the ITU-R656 recommendation, a size of 720 samples per line must be selected for each window. Bit No. Word - During blanked video lines SAV/EAV headers are suppressed in pairs. To assure vertical sync detection the V-flag in the EAV header of the last active video line is set to 1. Additionally, during field blanking all SAV/EAV headers (with the V-flag set to 1) are inserted.

Output Code Levels - output at the luma output port Output Code Levels correspond to ITU-R code levels: Y = 16...240 Black Level = 16 CrCb = 128112 An overview over the output code levels is given in Table 2-8. Helper signals are processed like the main video luma signals, i.e. they are subject to scaling, sample rate conversion and orthogonalization if activated. The adaptive comb filter processing is switched off for the helper lines. 2.9.8. Output Ports It is expected that further helper processing (e.g. nonlinear expansion, matched filter) is performed outside the VPC. All data and sync pins operate at TTL compliant levels and can be tri-stated via I2C registers. Additionally, the data outputs can be tri-stated via the YCOE output enable pin immediately. This function allows the digital insertion of a 2nd digital video source (e. g. MPEG aso.). To ensure optimum EMI performance data and clock outputs automatically adopt the driver strength depending on their specific external load (max. 50pF). Therefore no external resistors and/or inductors should be connected to these pins. Sync and Fifo control pins have to be adjusted manually via an I2C register. 2.9.9. Test Pattern Generator The YCrCb outputs can be switched to a test mode where YCrCb data are generated digitally in the VPC 323xD. Test patterns include luma/chroma ramps, flat field and a pseudo color bar. 2.10.1. Output Signals for PAL+/Color+ Support For a PAL+/Color+ signal, the 625 line PAL image contains a 16/9 core picture of 431 lines which is in standard PAL format. The upper and lower 72 lines contain the PAL+ helper signal, and line 23 contains signalling information for the PAL+ transmission. For PAL+ mode, the Y signal of the core picture, which is during lines 60-274 and 372-586, is replaced by the orthogonal composite video input signal. In order to fit the signal to the 8-bit port width, the ADC signal amplitudes are used. During the helper window, which is in lines 24-59, 275-310, 336-371, 587-622, the demodulated helper is signal processed by the horizontal scaler and the output circuitry. It is available at the luma output port. The processing in the helper reference lines 23 and 623 is different for the wide screen signaling part and the black reference and helper burst signals. The code levels are given in detail in Table 2-8, the output signal for the helper reference line is shown in Fig. 2- 17. 2.10.

The FP uses the integrator value to derive vertical sync and field information. 2.11. Video Sync Processing Fig. 2-18 shows a block diagram of the front-end sync processing. To extract the sync information from the video signal, a linear phase lowpass filter eliminates all noise and video contents above 1 MHz. The sync is separated by a slicer; the sync phase is measured. A variable window can be selected to improve the noise immunity of the slicer. The phase comparator measures the falling edge of sync, as well as the integrated sync pulse. The information extracted by the video sync processing is multiplexed onto the hardware front sync signal (FSY) and is distributed to the rest of the video processing system. The format of the front sync signal is given in Fig. 2-19. Frequency and phase characteristics of the analog video signal are derived from PLL1. The results are fed to the scaler unit for data interpolation and orthogonalization and to the clock synthesizer for line-locked clock generation. Horizontal and vertical syncs are latched with the line-locked clock. The sync phase error is filtered by a phase-locked loop that is computed by the FP. All timing in the front-end is derived from a counter that is part of this PLL, and it thus counts synchronously to the video signal. A separate hardware block measures the signal back porch and also allows gathering the maximum/minimum of the video signal. This information is processed by the FP and used for gain control and clamping.

Configurations Fig. 2-22 shows an enhanced configuration with two VPC 323xD's. In this case, one live and several still pictures are inserted into the main live video signal. The VPC pip processes the inset picture and writes the original or decimated picture into the field memory. The VPCmain delivers the main picture, combines it with the inset picture(s) from the field memory and stores the combined video signal into a second field memory for the SRC. To support PIP and/or scan rate conversion (SRC) applications, the VPC 323xD provides several control signals for an external field memory IC.

In addition an expert mode is available for advanced PIP applications. In this case the inset picture size, as well as the PIP window arrangements are fully programmable. Examples for the PIP mode programming are given in 5.2. 2.12.3. Predefined Inset Picture Size The predefined PIP display modes are based on four fixed inset picture sizes (see Table 2-10).

Acquisition and Display Window 2.12.5. Frame and Background Color The acquisition window defines the picture area of the input active video to be displayed as a inset picture on the screen. Two programmable frame colors COLFR1 and COLFR2 are available to high-light a particular inset picture. The display window defines the display position of the inset picture(s) on the screen. Instead of displaying the main picture it is possible to fill the background with a programmable color COLBGD (set SHOWBGD=1 in the register PIPMODE), e. g. for multi PIP displays on the full screen (see mode 6 and 10). The acquisition and display windows are controlled by I2C parameters HSTR, VSTR, NPIX and NLIN (see Fig. 2-25 and 2-26). They indicate the coordinate of the upper-left corner and the horizontal and vertical size of the active video area. In VPCpip or VPCsingle mode, these four parameters define the acquisition window in the decimated pixel grid, while in VPCmain mode they define the display window. COLFR1, COLFR2 and COLBGD are 16 bits wide each. Therefore 65536 colors are programmable. 2.12.6. Vertical Shift of the Main Picture The VPCmain mode supports vertical up-shifting of the main picture (e. g. letterbox format) to enable bottom insets (see mode 11). The vertical shift is programmable by VOFFSET. HSTR VSTR NLIN 2.12.7. Free Running Display Mode Acquisition Window In this mode a free running sync raster is generated to guarantee a stable display in critical cases like tuner scan. Therefore the LLC should be disabled (see Table 2-14). NPIX 2.12.8. Frame and Field Display Mode Active Video Fig. 2-25: Definition of the acquisition window HSTR In frame display mode, every field is written into the field memory. In the field display mode every second field is written into the field memory. This configuration is suitable for multi picture insets and freeze mode, since it avoids motion artifacts. On the other hand, the frame display mode guarantees maximum vertical and temporal resolution for animated insets. In the predefined mode the setting of frame/field mode is done automatically to achieve the best performance.

External Field Memory The requirements of the external field memory are: - FIFO type access with reset - write mask function: The increasing of the write address pointer and the over writing of the data should be controlled separately. - output disable function: tri-state table outputs For PIP applications, VPC 323xD supports 4:1:1 or 4:2:2 chrominance format. Table 2-15 shows the typical memory size for a 13.5 and 16 MHz system clock application. Table 2-15: Word length and minimum size of the field memory Chrominance format Word length [bit] Memory size [word] [bit] 4:1:1 12 245376 2944512 4:2:2 16 245376 3926016 RSTWR (reset write/read) resets the internal write/ read address pointer to zero. WE (write enable) is used to enable or disable incrementing of the internal write address pointer. IE (input enable) is used to enable writing data from the field memory input pins into the memory core, or to disable writing and thereby preserving the previous content of the memory (write mask function). RE (read enable) is used to enable or disable incrementing the internal read address pointer. OE (output enable) is used to enable or disable data output to the output pins. As serial write and serial read clock (SWCK and SRCK, respectively) of the field memory the line locked clocks LLC1 and/or LLC2 are used. The following 5 signals are generated by VPC 323xD to control the external field memory: 30 Micronas VPC 323xD PRELIMINARY DATA SHEET 2.12.10. Field-Buffer-Extension Mode The field-buffer-extension mode provides a joint lines free display of the inset picture for the single PIP modes. In this mode, two frames (four fields) of the inset picture are stored in the external field memory. The write/read controlling detects timing conflicts causing joint lines artifacts and suppresses these conflicts automatically. Therefore, the output pin FFRSTW of VPCpip has to be connected to the input pin RSTWPIP (see Fig. 2-22) For the predefined PIP modes 2...5, the field-bufferextension mode is enabled by FBEXT=1, in expert mode by FBEXT=1, TWOFB=1 and FRAMOD=1. The function of the I2C bits TWOFB and FRAMOD is shown in Table 2-24 Table 2-16: Function of the I2C bits TWOFB and FRAMOD FBEXT TWOFB FRAMOD Function x 0 0 use one field buffer, write only one input field of a frame into it x 0 1 use one field buffer, write both input fields of a frame into it 0 1 x use two field buffers, write two input fields of a frame alternate into them 1 1 0 use two field buffers, write input fields of a frame alternate into them, update the PIP frame while writing the inset picture 1 1 1 use four field buffers, write input fields of two frame alternate into them, update the PIP frame while writing the inset picture 2.12.11. Double-Windows-Extension Mode The double-windows-extension mode provides a joint fields free display of the second picture in Double-Window mode. The write/read controlling detects timing conflicts causing joint fields and suppresses these conflicts automatically by delaying the read control signals. The output pin FFRSTW of VPCpip should be connected to the input pin RSTWPIP (see Fig. 2-22) Micronas 31 VPC 323xD PRELIMINARY DATA SHEET The registers of the VPC have 8 or 16-bit data size; 16-bit registers are accessed by reading/writing two 8-bit data words. 3. Serial Interface 3.1. I2C-Bus Interface Communication between the VPC and the external controller is done via I2C-bus. The VPC has an I2C-bus slave interface and uses I2C clock synchronization to slow down the interface if required. The I2C-bus interface uses one level of subaddress: one I2C-bus address is used to address the IC and a subaddress selects one of the internal registers. For multi VPC 323xD applications the following three I2C-bus chip addresses are selectable via I2CSEL pin: A6 A5 A4 A3 A2 A1 A0 R/W I2CSEL 1 0 0 0 1 1 1 1/0 VSUP 1 0 0 0 1 1 0 1/0 VRT 1 0 0 0 1 0 0 1/0 GND Figure 3-1 shows I2C-bus protocols for read and write operations of the interface; the read operation requires an extra start condition and repetition of the chip address with read command set. 3.2. Control and Status Registers Table 3-1 gives definitions of the VPC control and status registers. The number of bits indicated for each register in the table is the number of bits implemented in hardware, i.e. a 9-bit register must always be accessed using two data bytes but the 7 MSB will be `don't care' on write operations and `0' on read operations.

Scaler Adjustment 3.2.1. Calculation of Vertical and East-West Deflection Coefficients In Table 3-3 the formula for the calculation of the deflection initialization parameters from the polynominal coefficients a,b,c,d,e is given for the vertical and East-West deflection. Let the polynomial be P / a + b(x - 0.5) + c(x - 0.5)2 + d(x - 0.5)3 + e(x - 0.5)4 The initialization values for the accumulators a0..a3 for vertical deflection and a0..a4 for East-West deflection are 12-bit values. The coefficients that should be used to calculate the initialization values for different field frequencies are given below, the values must be scaled by 128, i.e. the value for a0 of the 50 Hz vertical deflection is a0 = (a * 128 - b * 1365.3 + c * 682.7 - d * 682.7) / 128 In case of linear scaling, most of the scaler registers need not be set. Only the scaler mode, active video length, and the fixed scaler increments (scinc1/scinc2) must be written. The adjustment of the scaler for nonlinear scaling modes should use the parameters given in table 3-4. An example for `panorama vision' mode with 13.5 MHz line-locked clock is depicted in Fig. 3-2. The figure shows the scaling of the input signal and the variation of the scaling factor during the active video line. The scaling factor starts below 1, i.e. for the borders the video data is expanded by scaler 2. The scaling factor becomes one and compression scaling is done by scaler 1. When the picture center is reached, the scaling factor is held constant. At the second border the scaler increment is inverted and the scaling factor changes back symmetrically. The picture indicates the function of the scaler increments and the scaler window parameters. The correct adjustment requires that pixel counts for the respective windows are always in number of output samples of scaler 1 or 2.

They are necessary to tune the effective load capacitance of the PCBs to the required load capacitance CL of the crystal. The higher the capacitors, the lower the clock frequency results. The nominal free running frequency should match fp MHz. Due to different layouts of customer PCBs the matching capacitor size should be determined in the application. The suggested value is a figure based on experience with various PCB layouts.

Application Circuit 78 Micronas VPC 323xD PRELIMINARY DATA SHEET 5.1. Application Note: VGA mode with VPC 323xD In 100-Hz TV applications it can be desirable to display a VGA-signal on the TV. In this case, a VGA-graphic card delivers the H, V, and RGB signals. These signals are fed "directly" to the back-end signal processing. The VPC generates a stable line-locked clock for the 100-Hz system in relation to the VGA sync signals. While the V-sync is connected to the VGAV pin directly, the H-sync has to be pulse-shaped and amplitude adjusted until it is connected to one of the video input pins of the VPC. The recommended circuitry to filter the H sync is given in the figure below. +5V analog 100 47pF 1k 680 nF Video Input VPC 270 540 H 31kHz BC848B 1N4148 2k 1N4148 GND analog GND analog Fig. 5-1: Application circuit for horizontal VGA-input Micronas 79 VPC 323xD PRELIMINARY DATA SHEET 5.2. Application Note: PIP Mode Programming 5.2.1. Procedure to Program a PIP Mode For the VPCpip or VPCsingle: For the VPCpip or VPCsingle: 12. write the register PIPOPER to start filling a inset picture with live video. 1. set the scaler according to the PIP size to be used (see Table 2-11). 2. write the registers VPCMODE and PIPMODE according to the mode to be set. 3. in expert mode write the registers NLIN, NPIX and NPFB. 4. write the registers COLBGD, COLFR1, COLFR2, HSTR and VSTR, if a different value as the default one is used. 5. write the registers LINOFFS and PIXOFFS, if a different value as the default one or more than 4 inset pictures in the X or Y direction are used. 6. write the register PIPOPER to fill the frame and background of an inset picture. This step is repeated for all inset pictures in a multi PIP application. 13. Only for tuner scanning: write the register PIPOPER to stop filling a inset picture with live video and changing the channel. 14. repeat steps 12 and 13 for all inset pictures in a multi PIP application. 15. Only for VPCsingle: write the register PIPOPER to start filling the main picture part outside the inset picture(s) with live video. For the VPCmain: 16. write the registers HSTR and VSTR, if the PIP position should be changed. 17. write the register PIPOPER, to quit the PIP mode. In an application with a single VPC, step 7 - 11 and 16 - 17 are dropped. Additionally, the free running mode should be set in the cases shown in Table 2-14. For the VPCmain: 7. set the scaler to get a full size video (see Table 2-11). 5.2.2. I2C Registers Programming for PIP Control 8. write the registers VPCMODE and PIPMODE according to the mode to be set. To program a PIP mode, the register VPCMODE, PIPMODE and PIPOPER should be written always, all other registers are used only in the expert mode or if the default values are modified (see Table 5-1). 9. in expert mode write the registers NLIN, NPIX and NPFB. 10. write the registers COLBGD, HSTR and VSTR, if a different value as the default one is used. 11. write the register PIPOPER to start displaying PIP. Table 5-1: I2C register programing for PIP control I2C register update VPCMODE, PIPMODE, PIPOPER should be written always COLBGD, COLFR1, COLFR2, HSTR, VSTR should be written only, if the default values have to be modified LINOFFS, PIXOFFS VPC pip VPCmain VPCsingle only used in expert mode, when more than 4 inset pictures in the X or Y direction are used. not used. only used if a different value as the default one or more than 4 inset pictures in the X or Y direction are used NLIN, NPIX, NPFB 80 should be written, only in the expert mode.

No range check and value limitation are carried out in the field memory controller. An illegal setting of these parameters leads to a error behavior of the PIP function. The PIP display is controlled by the commands written into the register PIPOPER. For the VPCmain, the PIP display is turned on or off by the commends DISSTART and DISSTOP. For the VPC pip and VPCsingle, 8 commands are available: - WRFRCOL1, WRFRCOL2: to fill the frame of a inset picture with the color COLFR1 or COLFR2, - WRBGD, WRBGDNF: to fill a inset picture with the background color COLBGD, - WRPIC, WRPICNF, WRSTOP: to start and stop to write a inset picture with the active video, - WRMAIN: to start write the main picture part outside the inset picture(s) with the active video (only for VPCsingle). While WRPIC, WRSTOP, WRFRCOL1, WRFRCOL2 and WRBGD control a display with a frame (see Fig. 5-2), WRPICNF and WRBGDNF control a display without a frame (see Fig. 5-3). The number of the inset picture addressed by the current commend is given by bits NSPX and NSPY in the register PIPOPER. Micronas In the display window, the coordinate of the upper-left corner of the inset picture with NSPX=0 and NSPY=0 is defined by the registers LINOFFS and PIXOFFS. If maximal 4x4 inset pictures are used, no new setting of these registers is needed. The default setting LINOFFS=0 and PIXOFFS=0 takes effect. If more than 4x4 inset pictures are involved in a PIP application, these inset pictures should be grouped, so that the inset pictures in each group can be addressed by bits NSPX and NSPY. For writing each group, the registers LINOFFS and PIXOFFS should be set correctly (see Fig.5-4).
