This is Small Size LCD TV Processor with Video Decoder.

The MST703 is a high quality ASIC for NTSC/PAL/SECAM car TV application. It receives analog NTSC/PAL/SECAM CVBS and S-Video inputs from TV tuners, DVD or VCR sources, including weak and distorted signals, as well as analog YCbCr input from HDTV/SDTV systems.

Automatic gain control (AGC) and 10-bit 3-channel A/D converters provide high resolution video quantization. With automatic video source and mode detection, users can easily switch and adjust variety of signal sources.





1. Video Decoder :

(1) Supports NTSC, PAL and SECAM video input formats
(2) 2D NTSC and PAL comb-filter for Y/C separation of CVBS input
(3) Multiple CVBS and S-video inputs
(4) ACC, AGC, and DCGC (Digital Chroma Gain Control)

2. Analog Input :

(1) Supports RGB input format from PC, camcorders and GPS
(2) Supports YCbCr inputs from conventional video source and HDTV
