The BCM7411 introduces the advantages of the H.264 video compression
algorithm to today’s advanced consumer and broadcast applications. The
BCM741 1 is a dua l-cha nnel AVC/MPEG -2 dec oder ch ip capab le of fu ll HD real -
time decoding.
Broadco m’s H.26 4 Com pression Advantag e™ arch itect ure provi des three times
the compression power of M PEG-2. Systems incorpora ting the BCM7 411 have
superior image quality, improved system performance, and larger storage
capacit y wit h th e reduced bit rat es of H.264—also known as MPE G-4 A dvanced
Video Coding (AVC). The BCM7411 fully supports the MPEG-2 standard, so
that compatibility with existing media can be maintained.
The BCM7 411 supports the follo w in g de coding opera ti ons:
•1 HD (MPEG-2 or H.264) in real-time
•2 SD streams (MPEG-2 or H.264) in real -time
The H.264 Advantage
The H .264 coding stand ard incorporate s innovatio ns and techn iques devel oped
over decades of worldwide research into video compression. The algorithm
produces results far superior to the preceding MPEG standards. H.264 derives
much of its performance gain from complex motion estimation techniques,
integration of an in-loop deblocking filter, and brand-new spatial prediction
operations.
H.264 Support
•Complies wit h th e ISO/ I EC 14496-10 specification
•Decoder support for AVC High Profile streams up to level 4.1 with a 30 Mbps
maximum encoded bit rate restriction
•I, B, and P sl ices
•CABAC and CAVLC entro py dec odi ng
•Field/frame and picture adaptive decoding
•Macroblock adaptive field/fra m e de coding
•All intrab lock and int erbl o ck size s
•Resolutio ns supported: QCIF up to 1920 × 1088
MPEG-2 Support
The BCM7411 complies with the ISO/IEC 13818-2 specification and supports
Main Profile up to high level at 125 Mbps.
Transport/Program Stream Demultiplexer
The B CM7411 acc epts t ransport or pro gram stream s dep endin g on th e pre ferred
appli ca ti on, and parses the incoming v ide o, audio, and private dat a for decoding.
The BCM7411 monitors PCR information in the transport stream to adjust the
freq ue ncy of an external VCXO oscillator.
Digital Video Output Ports
The BCM7411 provides configurable digital video output ports for a glueless
interface to the BCM7038 or to a variety of video DACs. The outputs may be
configured for BT656 and HD-D V I.
System Control/Status Interface
The BCM7411 is intended for use as a peripheral system and requires a
controlling agent to configure and monitor its operation. The following interfaces
are suppor ted:
•PCI 32- bit int e rface
•Generi c 16-bit host inte rface
•SPI ser ial and GPIO inte rfaces
