The TW2824 has four high quality NTSC/PAL video decoders, dual color display controllers and dual video encoders. The TW2824 contains four 10-bit analog-to-digital converters, proprietary digital gain/clamp controller, high quality Y/C separator to reduce cross-noise and high performance dual scaler to provide various pictures. Four built-in motion and blind detectors can increase the feature of the security system. The TW2824 has a flexible video display controller including QUAD and MUX basic functions. The TW2824 also has an excellent graphic overlay function which displays character/bitmap, box and mouse pointer. The TW2824 contains two video encoders with four 10-bit digital-to-analog converters for providing 2 composite or S-video outputs.
