Multi-ch(4x4) 4K60 Video Processor : MS1827

Overview

The MS1827 is a multifunction audio/video processor integrating four independent HD audio/video inputs, four independent HD audio/video outputs, eight video-scaling paths, four OSD engines, 2 Gb on-chip DDR SDRAM, and a 32-bit controller. It targets multiview displays, video-wall and stitching systems, matrix switchers, and other multi-channel audio/video products.

Typical Applications

• Multiview processors and multi-channel video stitching systems
• 4K video matrices and audio/video switchers
• Video-wall controllers and display processors
