Output
The BCM7411 introduces the advantages of the H.264 video compression
algorithm to today’s advanced consumer and broadcast applications. The
BCM7411 is a dual-channel AVC/MPEG-2 decoder chip capable of full HD real-
time decoding.
Broadcom’s H.264 Compression Advantage™ architecture provides three times
the compression power of MPEG-2. Systems incorporating the BCM7411 have
superior image quality, improved system performance, and larger storage
capacity with the reduced bit rates of H.264—also known as MPEG-4 Advanced
Video Coding (AVC). The BCM7411 fully supports the MPEG-2 standard, so
that compatibility with existing media can be maintained.
The BCM7411 supports the following decoding operations:
• 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 standard incorporates innovations and techniques developed
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 with the ISO/IEC 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 slices
• CABAC and CAVLC entropy decoding
• Field/frame and picture adaptive decoding
• Macroblock adaptive field/frame decoding
• All intrablock and interblock sizes
• Resolutions 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 BCM7411 accepts transport or program streams depending on the preferred
application, and parses the incoming video, audio, and private data for decoding.
The BCM7411 monitors PCR information in the transport stream to adjust the
frequency 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-DVI.
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 supported:
• PCI 32-bit interface
• Generic 16-bit host interface
• SPI serial and GPIO interfaces
