The invention relates, in encoding/decoding systems, to an improved method of switching from a first coded video sequence to a second one. In order to avoid underflow or overflow of the decoder buffer, a transcoding of the input streams IS1 and IS2 is used toshift the temporal position of the switching point and to obtain at the output of the provided transcoders (11, 12) streams TS1 and Ts2 containing an identical entry point and the same decoder buffer characteristics. Application: switching of bitstreams generated according to the MPEG-1 and MPWG-2 standards. |
