1. In television technology, the process of converting image information from one format (standard) to another. Note: The conversion may, for example, affect (involve) the frame rate, the number of lines per frame, the analog resolution per scanning line, or (in digital systems) the number of pixels per scanning line. 2. In video post-production, the process of changing the image size (e.g., by cropping, zooming, or distorting the image geometrically. ) Note: The altered video signal is sampled and the samples are then processed by a suitable algorithm and a new set of samples is generated that is compatible with the specifications of the target system.
