MS1823 Multi-Function Video Processor
The MacroSilicon MS1823 is a multi-function video processor integrating six 10-bit video ADC channels, TV decoder/encoder, a triple 10-bit video DAC, and character OSD. It accepts interlaced or progressive analog video and graphics input, with dual independent playback engines for PIP/POP display.
The chip provides deinterlacing, video enhancement, 3D noise reduction, Y/C separation, and frame-rate conversion, enabling OEMs to build low-cost, high-quality video processing terminals with a highly integrated solution.
