- Present participle of scale.
A step in the video compression process that deals with the creation of the digital image according to the presentation resolution scale associated with the display device. Rather than digitizing the video signal in large scale, the codec is tuned to the scale of presentation in terms of horizontal and vertical pixels, thereby reducing the amount of data that must be digitized. In consideration of this factor, the aspect ratio must be standardized. See also aspect ratio, codec, compression, digital, pixel, resolution, signal, and video.
