Introduction

MS1826 is a multifunctional video processor featuring 4 independent HD audio/video input channels, 4 independent HD audio/video output channels, and 4 independent SPDIF/I2S audio signals configurable as either input or output. It supports 4 independent custom font-based OSD engines, handles both interlaced and progressive video or graphics input signals, and includes 4 independent video playback engines for multi-stream video playback. The product delivers high-quality video output with de-interlacing, video enhancement, and frame rate conversion capabilities.
