YUV Decomb (Deinterlace)

High-quality conversion of interlaced video to progressive-scan format

Short Description

Download:

Playback of interlaced video on a progressive-scan screen or a screen with a high frames-per-second (FPS) rate may result in unpleasant artifacts like a "comb." Generally, these artifacts are most noticeable on the edges of fast moving objects.

Special deinterlace processing is required to suppress comb artifacts.

We offer a high-quality deinterlace solution. In addition to software implementation, the algorithm’s reference C code is also ready for hardware implementation.

Primary Applications

  • Flat-panel plasma displays
  • 100 Hz progressive-scan television
  • LCD displays
  • Playback of interlaced video on progressive-scan displays
  • Digital video cameras
  • Video conversion and transcoding

Key Features

  • High visual quality for low-angle edges and static areas
  • Preserves scan rate (double rate) (e.g., converts 59.94 fields-per-second video to 59.94 frames-per-second video)
  • Fully automatic
  • Suitable for hardware implementation

Basic Deliverables

  • Source code for a reference implementation in C
  • C and assembly language source code for an implementation optimized for the PC (if required)
  • Algorithm description
  • Software description
  • Verification instructions
