The MS1825 is a multi-functions video processor chip. It consists of 4 independent channel HD signal inputs and 4 independent channel HD signal outputs, also includes 24 bits’ digital video input or output and 1 channel I²S & SPDIF digital audio input or output. Support 4 OSD windows with embedded font library. It can accept interlaced or progressive video input and graphic input. It has four independent video playback engines which can support PIP or POP application. Also can split one input picture into maximum four parts. In all video input & output channels, it provides a high quality display output. It is capable of advanced de-interlacing, video enhancement and frame rate conversion. OEMs can easily design a low cost and high quality system solution by MS1825’s high integration and Software support.
