1. Features description
MT8206
is a highly integrated single chip for LCD TV supporting video input and output
format up to HDTV. It includes 3D comb filter TV decoder to retrieve the best image from
popular composite signals. Embedded HDTV/VGA decoders enable the high quality video
reproduction. 24/16/8 bits digital port may accept all kinds of external digital input video source.
New 3
rd
generation advanced motion adaptive de-interlacer converts accordingly the interlace
video into progressive non-flicking video. 2D Graphic engine generates high quality UI
interface. Advanced full function color processing with fully 10-bit path provides high quality
video contents. Independent two Flexible scalars provide wide adoption to various LCD panels
for two of different video sources at the same time. Its on-chip audio processor decodes
analog signals from tuner with lip sync control, delivering high quality post-processed sound
effect to customers. On-chip microprocessor reduces the system BOM and shortens the
schedule of UI design by high level C program. MT8206 is a cost-effective and high
performance HDTV-ready solution to LCD TV product.
