BCM7020 Advanced High-Definition, Video-Graphics Subsystem supports requirements television set-top systems that require high-definition standard-definition decoding MPEG-2 streams with simultaneous high-definition standard-definition outputs. systems that require only standard-definition output, reduced-memory mode substantially reduces amount memory needed video decompressions process. video decoder also supports multiple stream standard definition decoding, providing both tiled video capability. BCM7020 graphics based Broadcom's advanced video/graphics technology that allows studio-quality text graphics displayed television-based systems. graphics compositing engine allows many windows graphics video layered with blending antialiasing, creating high-quality, rich display capability. on-board vector RISC processor provides graphics, antialiased text, effects. MPEG-2 DVB/DC2-compliant transport demux with three transport stream inputs advanced section filtering capability, descrambler, descrambler with ECB/CCB capability, ISO7816 smart card interfaces. descrambler
compliant with requirements transport stream interface. transport engine designed support personal video recorder (PVR) functions, allowing set-top support VCR-like functions, such fast forward/reverse, pause, record. BCM7020 supports record playback streams simutaineously. BCM7020 decodes both Dolby Digital (AC-3) MPEG multichannel compressed streams. Audio output provided over stereo DACs SPDIF. audio engine mixes separate audio streams generated from MPEG2/Dolby audio decompression circuitry, audio generated from CPU, audio input baseband audio input. These streams resampled mixed together with volume control. bridge incorporated provide complete solution bridging processor memory, local I/O, PCI. Main memory shared among video, graphics, CPUs, which increases system performance reduces cost. flexible powerful controller able between different busses memory, facilitating needs systems incorporating cable modem.
