Abstract

PURPOSE: To enhance the band compressibility as well as the picutre quality by encoding the TV signal via the suitable forecasting system which follows the actions of the TV screen.
CONSTITUTION: The analogous blocks of the using frame including picture element Zij are selected 1, 2...m in that order of alalogy at the preceding frame, so the square error features ε(1)<...ε(m) for each block. At the same time, Eq. (1) is obtained when the weight vector W=w(1), w(2)...w(m) determined in accordance with the degree of each block puls forecast value Zij are obtained with picture elements Yij(1) ...Yij(m) which are positioned at the corredponding positions in the analogous blocks of the preceding frame. With use of the forecast function expreseed by the linear combination shown in Eq. (1), the forecast accuracy, the compression effect and the picture quality can be enhanced respectively for the picture featuring microactions
