The MS1823 is a multi-functions video processor chip. It consists of six channels 10bit ADC modules and TV decoder, TV encoder module and a triple DAC module with OSD function. It can accept interlaced or progressive video input and graphic input. It has two independent video playback engines which can support PIP or POP application. In both two analog video input channels, it provides a high quality display output. It is capable of advanced de-interlacing, video enhancement, 3D noise reduction, Y/C cross talk suppression and frame rate conversion. OEMs can easily design a low cost and high quality system solution by MS1823’s high integration and Software support.
