ABSTRACT:
A picture transmission system for transmitting a video signal of compressed bandwidth in which the transmitting station is provided with circuitry for dividing a picture to be transmitted into a plurality of blocks containing a checkerboard pattern of picture elements and regularly sampling video signals along corresponding diagonal rows of picture elements in the respective blocks, and a transmitter responsive to the output of the sampling circuitry for transmitting the sampled video signals of one frame at a reduced bandwidth over a communication channel; and in which the receiving station is provided with a frame memory for temporarily storing transmitted video signals of one frame, and circuitry for playing back the video signals of one frame at the original high bandwidth frequency.
