摘要： Each of left and right images of a stereoscopic television picture is divided into a plurality of blocks and a position of one of the images is shifted in such a way that a difference between one picture signal (S.sub.L) in one block of one of the left and right images and the other picture signal (S.sub.R) in a block corresponding in position to the one block is minimized, to obtain a positional shift (p,q) between one picture and the other picture. A difference signal (S3) between one picture signal (S2) shifted by the positional shift (p,q) and the other picture signal (S.sub.R) is obtained in each block. The difference signal (S3) is compressed into a data compressed difference signal (S4). The compressed difference signal (S4), one video signal (S.sub.L) and the signal (S1) representative of the positional shift (p,q) are transmitted so that an amount of signals to be transmitted can be remarkably reduced. In addition, a transmission bandwidth can be further compressed by obtaining the difference signal only with respect to an object loaded at a short distance from the television cameras and concentrated in the center portion of the picture.

摘要： High resolution vertical and horizontal components of a high definition video signal are combined with a standard broadcast system video signal, such as the NTSC system, in which high frequency horizontal resolution components are sampled and used to modulate at least a first sub-carrier signal. The first sub-carrier is frequency interleaved onto the standard broadcast signal. Vertical high resolution components are time compressed and time division multiplexed onto top and bottom portions of the standard broadcast signal. The modified broadcast signal can be decoded by a standard receiver to display a standard resolution video image, while receivers designed to decode the modified signal can time division demultiplex the vertical high resolution components and demodulate the horizontal high resolution components, combine these components with the standard components, and generate a high definition video image.
