Verfahren und System zum Anpassen des Auffrischungszyklus an die Komplexität des Bildes

摘要

The method according to the invention for the application of the so-called refresh technique in redundancy reduction systems for television signal, uses an intra- field coding on odd fields and an interfield or intra- field coding on the subsequent even field, for the interruption of the predictive coding (refresh). Originally the refresh is now applied to a variable number of strips, to pairs of fields, depending on the complexity of the source signal. <IMAGE>
