Abstract
A file format structure for use with scalable video coding systems and methods, where a rate share operation box indicates which adaptation operation points for coded media are available in a file. The rate share operation box can include a characterization of the adaptation result for each adaptation operation point. In addition, the rate share operation box can include an identifier that indicates which algorithm was used in generating each adaptation operation point.
Claims10
A method, comprising:
- generating a file including a scalable media bitstream and associated data;
- and
- generating information related to adaptation operation points included in the associated data, wherein the information related to the adaptation operation points comprises an indication of an algorithm used to generate each of the adaptation operation points, a characterization of the adaptation result for each adaptation operation point, and an element indicating an adaptation path associated with each of the adaptation operation points, wherein the adaptation path associated with an adaptation operation point specifies a dependency level, temporal level, or quality level of the scalable media represented by the adaptation operation point;
- and
- wherein the adaptation result identifies whether the adaptation results into a desired total bitrate shared among all associated tracks or whether the adaptation results into a stable quality in each associated track.
