A television communications method and system particularly suitable for high definition, with narrow-band applications as for specialized broadcasting systems and video links using a block coding procedure to produce a system not wasteful of bandwidth caused by transmitting redundancies from multiple sources which do not contribute to picture quality. A differential order video encoding method (DOVE) provides a video coding scheme based on the need for true high-quality video with real-time TV encoding (14) and delivery in fifty percent of the bandwidth of the 4.5 MHz vestigial sideband suppressed television system in universal use. Efficient coding algorithms, based on the finding and eliminating multiple source redundancies, characterizes the redundancies and creates, in real-time, an efficient set of codes for encoding (25) only the information that is different, eliminating the need for full 4.5 MHz bandwidth.
