ENCODER AND METHOD OF ENCODING A SEQUENCE OF FRAMES

A method of encoding a sequence of frames includes applying a decorrelating transform to respective frames in the sequence to obtain respective transformed frames having an entropy lower than that of the respective frames in the sequence and data compressing the respective transformed frames so as t...

Zusammenfassung:	A method of encoding a sequence of frames includes applying a decorrelating transform to respective frames in the sequence to obtain respective transformed frames having an entropy lower than that of the respective frames in the sequence and data compressing the respective transformed frames so as to obtain respective encoded frames with an amount of data that is less than that of the respective transformed frames. At least one portion of the frame is encoded in an inter mode and at least one other portion of the frame is encoded in an intra mode. Respective frame portions in the respective frames are encoded in the intra mode in a dispersed manner such that, while a frame portion in one of the respective frames is forcibly encoded in the intra mode, at least one other frame portion is not forcibly encoded in the intra mode.
