Abstract

A video data stream having a video encoded thereinto and is described. It includes first timing information on first coded picture buffer, CPB, removal times to be applied at decoder side in case of buffering a complete version of the video data stream, and second timing information on second CPB removal times to be applied at decoder side for buffering a reduced version of the video data stream, differing from the video data stream by removal of a portion of the video data stream from the complete version of the video data stream. Corresponding video encoders, video decoders, network nodes, apparatuses for managing the coded picture buffer, CPB, of a video decoder, and apparatuses for splicing together video data streams are also referred to.
