video scaling


Also found in: Dictionary, Thesaurus, Medical.

video scaling

Changing the size of a video frame in order to match the native resolution of a TV or computer screen. Video scaling involves converting the resolution to a higher or lower format as well as a change in aspect ratio; for example, from 4:3 to 16:9. See upconvert.


Upconversion Is Critical
Scaling up from a lower resolution to a higher one (upconversion) is more critical than the other way around, and the quality of algorithms differs widely. These examples are images upscaled using a low-quality circuit (top) and the higher-quality circuit (bottom) in Anchor Bay's VP50Pro video processor.
