Claim 0:
1. A video encoder configured to:
encode a video into a video data stream; and
provide the video data stream with:
first timing information on first coded picture buffer (CPB) removal times to be applied at a decoder side when buffering a complete version of the video data stream, and
second timing information on second CPB removal times to be applied at the decoder side when 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.
