Video Upconversion: Facts and Fallacies

Quote:

The types of video processing commonly described as upconversion fall into three basic categories:
• Transcoding. Changing one signal format to another, such as composite-video to S- or component-video.
• Deinterlacing. Converting an interlaced video signal to progressive-scan, such as from 480i to 480p or 1080i to 1080p.
• Scaling. Changing the signal from one display resolution to another, such as from 480p to 720p.

Understanding how each of these works will help you decide when upconversion is necessary or desirable (and when it's not) and where in the signal chain the processing is best applied. At the end, I'll give you some basic rules for figuring all that out.
