CAST Basic Video Deinterlacer IP Core

The Basic Video Deinterlacer IP core, from CAST, converts incoming interlaced video to progressive video format for further processing or display. It accepts an industry-standard 8-bit ITU-R BT.656 video stream for wide compatibility. The core requires little ASIC or FPGA area and causes practically no video transmission delay. The Basic Video Deinterlacer core works standalone in a variety of applications and will provide integrated support for CAST’s upcoming revised H.264 1080p Video Encoder IP core.

Basic BT.656 Video Deinterlacer IP Core Features

  • Accepts an 8-bit, 4:2:2, YCrCr, video data stream in ITU Recommendation BT.656 video format
  • Supports NTSC, PAL, 1080i and all lower resolutions transmitted in conformance with the BT.656 format
  • Sophisticated BT.656 analyzer splits contents of the incoming video stream
  • Works with optional user-defined SAV (Start of Active Video) codes in the incoming video stream
  • Output frame rate equals the input field rate
  • Maximum horizontal resolution can be set as a pre-synthesis parameter to reduce logic resources
  • Includes write-through mode
  • Produces raster scan format of output video data
  • Minimum system clock speed equals two times the raw pixel clock speed
  • Fully synchronous design: all inputs and outputs are based on the rising edge of clock Includes complete documentation and testbench
