The BCM7411 is a dual-channel AVC/MPEG-2 decoder chip capable of full HD realtime 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 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 T he 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 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.
