Method of switching of coded video sequences and corresponding device

摘要

The invention relates to a method of switching from a first to a second coded video sequence when the bitrate of the second one is higher than the bitrate of the first one, and to a corresponding device. If the addition of the bits respectively associated to the last transmitted picture (02) of the first sequence and to the first transmitted picture (N1) of the second sequence gives at the decoding time of (02) a number greater than the size of the decoder's buffer, then the bitrate of the second sequence is increased with respect to the higher bitrate.
