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.

First claim

What is claimed is:

1. 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.

2. A method according to claim 1 , wherein the information related to the adaptation operation points further comprises an element indicating the number of the adaptation operation points present in the file.

3. A computer program product comprising a non-transitory computer-readable storage medium and computer instructions stored therein, the computer program instructions comprising program instructions configured to:
generate a file including a scalable media bitstream and associated data; and
generate 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 results 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.

4. A computer program product according to claim 3 , wherein the information related to the adaptation operation points further comprises an element indicating the number of the adaptation operation points present in the file.

5. An apparatus generator configured to generate a file including a scalable media bitstream and associated data, comprising:
a processor; and
a memory unit operatively connected to the processor and
computer code for 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.

6. An apparatus according to claim 5 , wherein the information related to the adaptation operation points further comprises an element indicating the number of the adaptation operation points present in the file.

7. A method comprising:
parsing a file including a scalable media bitstream and associated data;
parsing from the associated data, information related to adaptation operation points, wherein the information related to the adaptation operation points comprises an indication of an algorithm used to generate each of the adaptation operation points, 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;
choosing an adaptation operation point based on the information on adaptation operation points, and a characterization of the adaptation result for each adaptation operation point, 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; and
parsing the file according to the adaptation operation point.

8. A method according to claim 7 , wherein the information related to the adaptation operation points further comprises an element indicating the number of the adaptation operation points present in the file.

9. A computer program product comprising a non-transitory computer-readable storage medium and computer program instructions stored therein, the computer program instructions comprising program instructions configured to:
parse a file including a scalable media bitstream and associated data;
parse, from the associated data, information related to adaptation operation points, wherein the information related to the adaptation operation points comprises an indication of an algorithm used to generate each of the adaptation operation points, 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;
choose an adaptation operation point based on the information on adaptation operation points, and a characterization of the adaptation result for each adaptation operation point, 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; and
parse the file according to the adaptation operation point.

10. A computer program product according to claim 9 , wherein the information related to the adaptation operation points further comprises an element indicating the number of the adaptation operation points present in the file.
