The BCM7031 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.
