Description

The BCM7021 Advanced High Definition, Video-Graphics Subsystem supports the requirements of interactive 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. The BCM7021 also supports multiple stream standard definition decoding, providing both tiled video and PIP capability. Supports recorder playback up to four channels.

The BCM7021 graphics are based on Broadcom's advanced video/graphics technology that allows studio-quality text and graphics to be displayed on television-based systems. The BCM7021 compositing engine allows for many windows of graphics and video to be layered with blending and antialiasing, creating high-quality, rich display capability.
