Overview

  • MDIN-640 is a highly integrated SoC that can do UHD(4K60) video processing for quad scalers with embedded SDRAMs. It includes many I/O interfaces, such as quad HDMI receivers, quad HDMI transmitters, quad digital video I/O ports, digital audio ports, and a USB/UVC controller interface. The video resolution of the I/O interface is up to 4096x2160@60Hz for progressive video and up to 1080i for interlaced video.
  • MDIN-640 provides a lot of functions including, up/down scaling, seamless switching, frame rate conversion, deinterlacing, HDR/SDR conversion, any degree rotation, warping, edge blending, genlock, up/downstream color keying, waveform display, vectorscope, histogram display, keystone correction, bitmap OSD & font OSD, and noise reduction. MDIN-640 supports YCbCr(4:4:4 or 4:2:2) and RGB 4:4:4 color processing with 8/10/12-bit precision per color component.
  • MDIN-640 is suitable for many industry 4K60 video products, such as digital signages, matrix switchers, multi-view displays, video wall displays, KVM switchers, converter boxes, broadcast monitors, medical imaging, video projectors, and video presentation systems.
