The BCM7020 Advanced High Definition, Video/Graphics Subsystem supports the requirements of television and set-top box systems that require high definition or standard definition decoding of MPEG-2 streams with simultaneous high-definition and standard definition outputs. For systems that require only standard-definition output, a reduced-memory mode substantially reduces the amount of memory needed for the video decompressions process. The video decoder also supports multiple-stream, standard definition decoding, providing both tiled video and PIP capability.
