Design How-To  
9/30/2005   Post a comment
Most video sources, including DVD, standard-definition TV, and 1080i high-definition TV, transmit interlaced images. Instead of transmitting each video frame in its entirety (what is called progressive scan), most video sources transmit only half of the image in each frame at any given time. The founder and engineering architect of Teranex, a unit of Silicon Optix, explains how HQV video processing does de-interlace better.
