BCM7021 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. BCM7021 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 complies 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. BCM7021 supports record playback streams simultaneously, with optional 3DES encryption/decryption. BCM7021 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. BCM7021 ideal solution where maximum system design flexibility performance key. bi-endian architecture full capability work with system configuration.
