ABSTRACT:
A receiver for a high-definition television signal, in which the signal prior to transmission is sub-sampled on a segmented basis according to the degree of movement, has an input terminal (1) which receives the sub-sampled signal which is applied to an inverse shuffler (2) which shuffles the pixels of each block in a manner which is the inverse to that performed prior to transmission. The output of shuffler (2) is applied to a first delay arrangement (4) which provides one or more delays of an integral number of fields periods and whose delayed and undelayed outputs are applied to an input field selector (6) to produce a changed sequence of fields to that received. The selector output is applied to a processing arrangement (8) in which the signal of changed field sequence is subjected to spatial interpolation and/or temporal interpolation and the resulting interpolated signal applied to a second delay arrangement (10) providing one or more delays of an integral number of fields periods. The delayed and undelayed outputs of delay arrangement (10) are applied to an output field selector (12) to produce an output in which the original field sequence is restored.
