ABSTRACT:
A method and apparatus for reducing the amount of video information which is transmitted to a receiver, while still enabling the receiver to reconstruct a representation of the original video source material. In a preferred embodiment, a 60 frames per second progressively scanned video signal is transmitted at a 30 frames per second rate accompanied by decoding information. In short, every other frame is deleted and a respective nearest neighbor is selected to represent the deleted frame. This selection is represented by a digital selection information. Thus the transmitted frame information can be reconstructed into the original video source material after decoding with the digital selection information.
