ABSTRACT:
A method and apparatus for transmitting and receiving 3-dimensional video images of a scene using conventional video transmission channels. The method requires the production of two images of the scene obtained from slightly different viewing angles, the images being sampled so as to generate for each image sets of component picture elements which are then sub-sampled according to a predetermined pattern, so as to form first and second sets of signals for each image. Both sets of signals corresponding to one of the images are transmitted to enable a conventional receiver to display a 2-dimensional image. A second set of signals for the other image is predicted both at the transmitter and at a modified receiver, enabling a correction signal corresponding to the difference between the predicted and actual signals to be transmitted to the modified receiver which regenerates the actual signals and displays them together with the corresponding first set of signals of the first image.
