Abstract
The size of a color television picture field is changed without changing the size of the raster. This is achieved in an apparatus that includes means responsive to a field of television video signals for sampling same and providing a predetermined number of samples of television video signals per line and a predetermined number of lines per field and means responsive to the predetermined number of samples per line and lines per field for providing a full field of television video signals. Size reduction is accomplished by causing the first mentioned means to skip samples provided at the output thereof in groups of N, where N is the number of samples in a color subcarrier cycle, and to skip line pairs of the field.
