MS1820

MS1820 is a versatile video processing chip. It consists of a 10-bit three-channel ADC module, a television encoder module, a 10-bit three-channel DAC module, and an embedded on-screen display (OSD) functionality. It can accept interlaced or progressive video inputs as well as graphic inputs. It is capable of advanced deinterlacing, video enhancement, 3D noise reduction, Y/C crosstalk suppression, and frame rate conversion.
