BCM7400B

Description

The BCM7400 is a dual-channel high definition satellite, cable, and IP set-top box DVR solution offering integrated AVC(H.264/MPEG-4 Part 10), MPEG-2, MPEG4 Part 2, DivX, and VC-1 video decoding technology. BCM7400B combines a data transport processor, two high-definition AVC/MPEG-2/VC-1 video decoders, two advanced-audio decoders, 2D and 3D graphics processing, high-quality video scaling and motion adaptive deinterlacing, seven video DACs, dual stereo high-fidelity audio DACs, a dual-threaded 350-MHz MIPS32 with FPU class CPU, and a peripheral control unit providing a variety of set-top box control functions. The BCM7400 supports either DDR1 or DDR2 memory architectures.

The MPEG-2 DVB-compliant transport stream/PES parser and demultiplexer is capable of simultaneously processing 256 PIDs via 128 PID channels in up to six independent external transport stream inputs and four internal playback channels. BCM7400B PID channels can be used by the record, audio, and video interface engine, PCR processing, message filter, and for output via the high-speed transport or remux module. The data transport module can be configured to support eight record channels for PVR functionality and six AV channels to interface to audio and video decoders.
