Abstract
A method of decoding a compressed video sequence, wherein image frames are entered into a buffer memory in connection with the decoding. The video sequence includes an indication relating to at least one discontinuity in the numbering of the image frames, which indication is decoded from the video sequence. Then, in response to the indication, the buffer memory is configured to provide a number of image frames corresponding to a discontinuity in the numbering of the image frames, and the image frames provided by the buffer memory are used in the decoding process. Preferably, said indication informs that at least one discontinuity in the numbering of the image frames in the video sequence are intentional, and the number of image frames provided by the buffer memory are used in place of image frames that do not exist at a decoder.
