Abstract
A high definition television signal from a source such as a television camera (1) is applied to three parallel processing branches the operation of each branch being determined by a range of motion. An 80 ms branch (3, 4, 5) and a 20 ms branch (6, 7, 8) each respectively have a two dimensional low pass filter, a sub-sampler and a line shuffler. A 40 ms branch (9,10) only has a two dimensional filter and a sub-sampler. A motion estimator (14) determines the degree of movement of picture blocks and a decision unit (13) decides on the appropriate branch, the motion vectors for the 20 ms and 40 ms branch and the blocks to which these are applied. This information is applied to a DATV formatting device (15) which produces a menu of motion vectors and codewords for each block. A switch (11) selects the appropriate branch for each block.
