Summary:PCT No. PCT/GB87/00116 Sec. 371 Date Oct. 14, 1987 Sec. 102(e) Date Oct. 14, 1987 PCT Filed Feb. 17, 1987 PCT Pub. No. WO87/05179 PCT Pub. Date Aug. 27, 1987.The invention provides a system of encoding broadcast-quality television signals to enable their transmission as a embedded code. A preferred embodiment provides a hybrid interpolative/predictive coding algorithm acting on all sampled sites of a television signal. One sub-set of samples are adaptively interpolatively coded; a 3-state interpolator switching signal is produced at each site, redundancy is removed and the signal transmitted. The interpolator switching signal also acts as a descriptor at sites surrounded each sample to be predicted. Adaptive prediction is used for the other sub-set of samples the particular predictor used at a sample site being determined by the surrounding descriptors.
