Abstract

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. Each of the periods may include one or more representations. The metadata may include information used to describe a relationship between the representations, and include information for terminals having different display bit depth.

Claims

1. A method of providing media content performed by a DASH (Dynamic Adaptive Streaming over HTTP) client, the method comprising:

receiving a Media Presentation Description (MPD) of a media content; and

accessing segments of the media content based on information provided by the MPD,

wherein the MPD includes one or more periods,

wherein each of the periods includes one or more adaptation sets,

wherein each of the adaptation sets includes one or more representations,

wherein each of the representations includes one or more segments,

wherein the MPD includes one or more attributes or elements that are common to each of the periods, each of the adaptation sets, each of the representations, and each of the segments,

wherein the period includes one or more attributes or elements that are common to each of the adaptation sets, each of the representations, and each of the segments for that period,

wherein the adaptation set includes one or more attributes or elements that are common to each of the representations and each of the segments for that adaptation set, and

wherein the representation includes one or more attributes or elements that are common to each of the segments for that representation.

2. The method of claim 1, wherein the attribute included at an MPD level is a suggestedPresentationDelay.

3. The method of claim 1, wherein the element included at a period level is a SegmentTemplate.

4. The method of claim 1, wherein the element included at an adaptation set level is a SegmentTemplate.

5. The method of claim 1, wherein the attribute included at an adaptation set level is a subsegmentStartsWithSAP.

6. The method of claim 1, wherein the element included at a representation level is a SegmentBase.

7. The method of claim 1, wherein the element included at a representation level is a SegmentTemplate.

8. A method of providing media content performed by a server or multiple servers, comprising:

transmitting a Media Presentation Description (MPD) of a media content to a client;

receiving a request, from the client, for a segment of the media content;

transmitting the media content to the client,

wherein the MPD includes one or more periods,

wherein each of the periods includes one or more adaptation sets,

wherein each of the adaptation sets includes one or more representations,

wherein each of the representations includes one or more segments,

wherein the MPD includes one or more attributes or elements that are common to each of the periods, each of the adaptation sets, each of the representations, and each of the segments,

wherein the period includes one or more attributes or elements that are common to each of the adaptation sets, each of the representations, and each of the segments for that period,

wherein the adaptation set includes one or more attributes or elements that are common to each of the representations and each of the segments for that adaptation set, and

wherein the representation includes one or more attributes or elements that are common to each of the segments for that representation.

9. The method of claim 8, wherein the attribute included at an MPD level is a suggestedPresentationDelay.

10. The method of claim 8, wherein the element included at an MPD level is a SegmentTemplate.

11. The method of claim 8, wherein the element included at an adaptation set level is a SegmentTemplate.

12. The method of claim 8, wherein the attribute included at an adaptation set level is a subsegmentStartsWithSAP.

13. The method of claim 8, wherein the element included at a representation level is a SegmentBase.

14. The method of claim 8, wherein the element included at a representation level is a SegmentTemplate.

16. The method of claim 8, wherein the SegmentBase element is included at a period level.

17. The method of claim 8, wherein the SegmentBase element is included at an adaptation set level.

18. The method of claim 8, wherein the SegmentBase element is included at a representation level.

15. A method of providing media content performed by a DASH (Dynamic Adaptive Streaming over HTTP) client, the method comprising:

receiving a Media Presentation Description (MPD) of a media content; and

accessing segments of the media content based on information provided by the MPD,

wherein the MPD includes one or more periods,

wherein each of the periods includes one or more adaptation sets,

wherein each of the adaptation sets includes one or more representations,

wherein each of the representations includes one or more segments,

wherein information on a location, availability or property for the one or more segments in a representation are comprised in a SegmentBase element.

19. A method of providing media content performed by a DASH (Dynamic Adaptive Streaming over HTTP) client, the method comprising:

receiving a Media Presentation Description (MPD) of a media content; and

accessing segments of the media content based on information provided by the MPD,

wherein the MPD includes one or more periods,

wherein each of the periods includes one or more adaptation sets,

wherein each of the adaptation sets includes one or more representations,

wherein each of the representations includes one or more segments,

wherein information on a location, availability or property for the one or more segments in a representation are comprised in a SegmentTemplate element.

20. The method of claim 19, wherein the SegmentTemplate element is included at a period level.

21. The method of claim 19, wherein the SegmentTemplate element is included at an adaptation set level.

22. The method of claim 19, wherein the SegmentTemplate element is included at a representation level.

23. The method of claim 19, wherein a duration attribute and a SegmentTimeLine element are included at a period level, an adaptation set level, or a representation level.

24. The method of claim 19, wherein when a SegmentTimeLine element is absent, a duration attribute is comprised in the SegmentTemplate element.

25. A method of providing media content performed by a DASH (Dynamic Adaptive Streaming over HTTP) client, the method comprising:

receiving a Media Presentation Description (MPD) of a media content; and

accessing segments of the media content based on information provided by the MPD,

wherein the MPD includes one or more periods,

wherein each of the periods includes one or more adaptation sets,

wherein each of the adaptation sets includes one or more representations,

wherein each of the representations includes one or more segments,

wherein information on a location, availability or property for the one or more segments in a representation are comprised in a SegmentList element.

26. The method of claim 25, wherein the SegmentList element is included at a period level.

27. The method of claim 25, wherein the SegmentList element is included at an adaptation set level.

28. The method of claim 25, wherein the SegmentList element is included at a representation level.

29. The method of claim 25, wherein a duration attribute and a SegmentTimeLine element are provided.

30. The method of claim 25, wherein when a SegmentTimeLine element is absent, a duration attribute is comprised in the SegmentList element.

31. A method of providing media content performed by a server or multiple servers, comprising:

transmitting a Media Presentation Description (MPD) of a media content to a client;

receiving a request, from the client, for a segment of the media content;

transmitting the media content to the client,

wherein the MPD includes one or more periods,

wherein each of the periods includes one or more adaptation sets,

wherein each of the adaptation sets includes one or more representations,

wherein each of the representations includes one or more segments, and

wherein information on a location, availability or property for the one or more segments in a representation is comprised in a SegmentList element.

32. The method of claim 31, wherein the SegmentList element is included at a period level.

33. The method of claim 31, wherein the SegmentList element is included at an adaptation set level.

34. The method of claim 31, wherein the SegmentList element is included at a representation level.
