MSD8220
GENERAL DESCRIPTION
MSD8220LBMP is a highly integrated TV SoC solution for ATSC digital television platform. Integrating latest
advanced technologies from MStar Semiconductor, the world leading TV SoC provider in TV industry,
MSD8220LBMP provides the most cost-efficient solution for multimedia TV application with creative and
attractive features exclusively presented.
In order to achieve the lowest BOM cost in a multi-media TV platform, MSD8220LBMP integrates DTV,
ATSC/QAM demodulator, TV/multi-media all-purpose AV decoder, VIF demodulator, and advanced
Sound/Video processors into a single device. This not only reduces the overall BOM significantly, but also
facilitates the design of originally-complicated TV systems for developers. In addition, the memory-embedded
solution provided by MSD8220LBMP can reduce the excessive work of memory interface routing on board and
the risk of memory performance degradation while powering cost-down in the total system.
The powerful multimedia A/V decoder inside MSD8220LBMP is hosted with a dedicated hardware video codec
engine to secure fast and stable video streaming playback. Moreover, MSD8220LBMP is equipped with a DSP
specifically designated for audio application, including digital audio format decoding and advanced sound
effects, and a high performance RISC CPU to manipulate all possible routines and house-keeping activities.
With extendable USB 2.0 interface, an MSD8220LBMP based system can turn into a high quality media-center
in a simple manner.
MSD8220LBMP supports the latest MHL technology, which allows user to stream audio and full HD video from
mobile devices to televisions. Power management and low-power design of MSD8220LBMP makes it possible
to charge MHL devices even in standby mode. The MHL/HDMI dual-purpose port on MSD8220LBMP will
enable charging if MHL devices are automatically detected.
For standard users, the MSD8220LBMP provides multi-standard analog TV support with adaptive 3D video
decoding and VBI data extraction. The built-in audio decoder is capable of decoding FM, AM, A2, BTSC and
EIA-J sound standards. MSD8220LBMP also supplies all the necessary A/V inputs and outputs to complete a
receiver design including HDMI receivers and component video ADCs. All input selection multiplexers for video
and audio are integrated, including full SCART support with CVBS output. The equipped MStar MStarACE-6
color engine is the latest masterpiece of MStar technologies, providing excellent video and picture quality in
Full-HD and large-scale display system. MSD8220LBMP also supports an ultra low power standby mode to
meet the latest energy legislative requirements without any additional hardware.
