Claim 15:
16. A method of forwarding a reduced version of a video data stream, the method comprising:
receiving a complete version of the video data stream comprising:
first timing information on first coded picture buffer (CPB) removal times to be applied at a decoder side for buffering the complete version of the video data stream, and
second timing information on second CPB removal times to be applied at the decoder side for buffering a reduced version of the video data stream, the reduced version of the video data stream differing from the complete version of the video data stream by removal of at least one encoded picture, wherein the second timing information defines the second CPB removal times by way of timing modification information for modifying the first CPB removal times to yield the second CPB removal times;

removing the at least one encoded picture from the complete version of the video data stream to obtain the reduced version of the video data stream; and
forwarding the reduced version of the video data stream.
