A. Analog Switch and Video input.
MT8202 is a highly integrated video and audio single chip processor for emerging
HDTV-Ready LCD TV. It includes one 3D/2D TV Decoder recovering the best image from
CVBS, and in addition, its analog input also support popular S-Video, Component, VGA video
source. On-chip advanced motion adaptive de-interlacer (MDDitm) converts accordingly the
interlace video into smooth non-flicking progressive motion pictures.
Analog switch is built in MT8202 and accept CVBS, YPbPr, S-Video, RGB signal directly to
internal video front end. For most system application, there is no need to add external
components to add analog video multiplexer on board.
The video ADC sample analog input signals. After ADC, all signal processing is digital
domain.The source select multiplex all inputs from digital and analog video ports and route
them into Main and PIP data path.
B. 3D comb filter, Video Decoder, Deinterlacer and Scaling controller.
MT8202 includes 3D comb filter TV decoder to retrieve the best image from popular
composite signals. Embedded HDTV/VGA decoders let the high bandwidth input signals
perfectly reproduced. 24/16/8 bits digital port may accept all kinds of external digital input
video source. New 2nd generation advanced motion adaptive de-interlacer converts
accordingly the interlace video into progressive one with overlay of a 2D Graphic processor.
Advanced full function color processing with fully 10-bit path provides high quality video
contents. Independent two Flexible scalers provide wide adoption to various LCD panels for
two of different video sources at the same time. MT8202 supports alpha blending for Video
and two OSD planes. It also supports 10bit gamma correction and advanced dithering
processing for LCD display with 6/8/10 bit output.
