High-Definition Video Deinterlacing Using FPGAs
Deinterlacing was developed to address a legacy problem: the interlaced video that was required by old analog televisions must be converted to be shown on today's digital televisions. An interlaced video is a succession of 50/60 fields per second, where each field carries only half of the rows that are displayed in each frame of video. In some ways, interlaced video was an elementary compression technique when older display technologies were based on Cathode Ray Tubes (CRTs). Today, deinterlacing is an important video processing function and is required in many systems.
