<p>A picture type identifier, indicating one of intra-picture coding (an I-picture), forward or backward predictive coding (a P-picture) and bi-directionally predictive coding (a B-picture), is included (108) with a picture signal when the signal (100) is encoded (102) and when the signal is decoded. Each of initial and subsequent encoding and decoding is a function of the included picture type. <IMAGE></p> |
