MS1825
——————————————————————————————————————————————————————————
The
MS1825 is a multi-functions video processor chip. It consists of 4 independent
channel HDMI inputs and 4 independent channel HDMI 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.
