The BCM7412 is an AVC/VC-1/MPEG-2 decoder chip capable of full HD real-time decoding. Broadcom's H.264 Compression AdvantageTM architecture provides three times the compression power of MPEG-2. Systems incorporating the BCM7412 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 BCM7412 fully supports the MPEG-2 standard, so that compatibility with existing media can be maintained. The BCM7412 supports both HD and SD formats (MPEG-2, H.264 or VC-1) in real time. Transport/Program Stream Demultiplexer The BCM7412 accepts transport or program streams depending on the preferred application, and parses the incoming video, audio, and private data for decoding. The BCM7412 monitors PCR information in the transport stream to adjust the frequency of an external VCXO oscillator. Digital Video Output Port The BCM7412 provides a configurable digital video output port for a glueless interface to the BCM7038 or to a variety of video DACs. The output may be configured for BT.656 and HD-DVI. Still Image Decoder (SID) The SID still-image decode accelerator operates autonomously, with its own general-purpose RISC processor that handles image headers, depacketization, and input/output DMA. It supports JPEG, PNG, MNG, GIF, RLE formats 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. System Control/Status Interface The BCM7412 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 interface 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 40 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 x 1088 BCM7412 Specifications Parameter Logic supply SDRAM I/O supply I/O supply Maximum power dissipation Operating temperature Storage temperature Value 1.2 2.6 3.3 2.5 0 to 70 -30 to +125 Unit/Description V V V W C C MPEG-2 Support The BCM7412 complies with the ISO/IEC 13818-2 specification and supports Main Profile up to high level at 125 Mbps. VC-1 Support The BCM7412 supports Advanced Profile VC-1 streams up to 40 Mbps, as well as Simple and Main, as defined in the proposed SMPTE specification.
