Abstract
Aspects of the present invention relate to systems, methods and devices for signaling layer characteristics of multi-layer video sequences and for employing these signals in encoding, decoding and translation operations. Some aspects relate to methods and systems for creating an enhanced multi-layer bitstream wherein a scalable, multi-layer representation of a video sequence is enhanced by determining a bitrate characteristic of a layer of the video sequence, wherein the bitrate characteristic relates to a non-scalable, single-layer representation of the layer and attaching bitrate characteristic data to the scalable, multi-layer representation to form an enhanced scalable representation.
