摘要: The disclosed subject matter, in one embodiment, provides techniques to signal inter-layer texture and motion prediction from different direct dependent reference layers. In certain exemplary arrangements, techniques are provided which include one or more syntax elements in a high level syntax structure, e.g., the slice segment header, indicating such different direct dependent reference layer(s).

摘要: Disclosed herein are techniques and computer readable media containing instructions arranged to determine a bit allocation for a temporal base layer and at least one temporal enhancement layer. The techniques are enhanced to yield improved reproduced quality for the case where both a temporal base layer and at least one temporal enhancement layer is being used. An exemplary method for determining a bit allocation to one base layer includes initializing a bit allocation between the base layer and the at least one enhancement layer, determining a quality difference between the base layer and the at least one enhancement layer, expressed, for example, in the Quantizer Parameter of the last picture of each layer within a GOP, and determining a new bit allocation between the base layer and the at least one enhancement layer based on the quality difference and at least one constant factor.

摘要: Techniques to determine a level id in a layered bitstream are disclosed, such that the same level id can be used for all layers of a scalable bitstream. Also disclosed are techniques to signal level ids for sub bitstreams that can be indicative of lower computational requirements than the level id used for the layered bitstream.
