MS1826
HDMI Video Processor

General Description

The MS1826 is a multi-functions video processor chip. It consists of 4 independent channel HDMI inputs and 4 independent channel HDMI outputs, also includes 4 channels I2S & SPDIF digital audio input or output. Support 4 OSD windows with user defined font library. It can process interlaced or pr gressive video input and graphic input. It has four independent video playback engines which can support PIP or POP application. Also can split one input video 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.
