概要

The TW8820 incorporates many of the features required to create a multi-purpose Video Door phone intercom LCD display system in a single package. It integrates a high quality 2D comb NTSC/PAL/SECAM video decoder, high quality scaler, and image enhancement functions which include Black and White Stretch and Gamma Correction. It also supports panoramic scaling for conversion to wide screen display. TW8820 supports analog composite video input and the output supports a wide variety of digital LCD panel types with its built-in timing controller.
