M
T8206 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.
