MS1826A

——————————————————————————————————————————————————————————

The MS1826A is a multi-functions video processor chip. It consists of 4 independent channel HD input and 1 independent channel HD output, and also includes 1 channel I²S & SPDIF digital audio input or output. It supports 4 OSD windows with user defined font library. It can process interlaced or progressive video input and graphic input. It has four independent video playback engines which can support PIP or POP application. It is capable of advanced de-interlacing, video enhancement and frame rate conversion.
