The MS1826B is a multi-functions video processor chip. It consists of 4 independent channel HD output and 1 channel HD input, 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 can split one input video into maximum four parts. It is capable of advanced de-interlacing, video enhancement and frame rate conversion.
