The TW8831 incorporates many of the features

required to create multi-purpose in-car LCD display

system in a single package. It integrates a high

quality 2D comb NTSC/PAL/SECAM video decoder,

triple high speed RGB ADCs, high quality scaler, and

images enhancement functions which include Black

and White Stretch and etc. It also supports

panoramic scaling for conversion to wide screen

display. On the input side, it supports a rich

combination of CVBS, S-video. On the output side, it

supports variety of digital panel types with its built-in

timing controller.
