Abstract
(EN)
A system for encoding and/or decoding a video bitstream that includes a base bitstream and enhancement bitstreams representative of a video sequence. The receiver receives a video parameter set and a video parameter set extension, where the video parameter set extension includes decoder picture buffer parameters.
