Abstract
A technique is provided for simultaneously displaying on a television screen juxtaposed pictures from two independent image sources. The required picture compression is achieved by storing analog samples of the video signals in an analog memory at one frequency and retrieving the samples at a higher frequency for display. A 2 to 1 picture compression is attained, for example, by retrieving the samples at twice the frequency at which they are stored.
