Overview

  • MDIN-325/325A is a highly integrated single chip implementation of deinterlacing, format conversion, video enhancement and graphic OSD.
  • MDIN-325/325A receives any format of interlaced scan video up to 1080i and progressive scan video up to full-HD, and performs deinterlacing and format conversion to produce any desired format of interlaced or progessive scan video up to full-HD with excellent signal quality preservation.
  • MDIN-325/325A provides high quality edge preserving deinterlacing with the 5th generation motion adaptive 3-D deinterlacing algorithm and performs proper processing for various speed motion and film video sources.
  • And especially it has 3-D NR, PIP/POP, 4Ch. D1 in/out and frame rate conversion functions.
  • MDIN-325/325A provides a versatile 2-D graphics engine with bitmap and character mode.
  • MDIN-325/325A's high quality deinterlacing, format converting, video enhancement and OSD capability are suitable for digital display applications such as digital video recorder(DVR), IP camera, set-top-box, DVD player, Blu-ray player, TV box, AV receiver and scan converter system.
