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, the period, the adaptation set, the representation, or the segments includes one or more attributes or elements, and

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

2. The method of claim 1, wherein the attribute included at an MPD level is a maxSegmentDuration, wherein the maxSegmentDuration is a maximum duration of a segment in a representation.

3. The method of claim 1, wherein the element included at an adaptation set level is an Accessibility, wherein the Accessibility specifies information on an accessibility scheme.

4. The method of claim 1, wherein the attribute included at an adaptation set level is an audioSampleRate, wherein the audioSampleRate specifies a sampling rate of an audio media component type.

5. The method of claim 1, wherein the element included at an adaptation set level is an AudioChannelConfiguration, wherein the AudioChannelConfiguration specifies an audio channel configuration of an audio media component type.

6. The method of claim 1, wherein the attribute included in an adaptation set level is a contentType, wherein the contentType specifies a type of a media content component.

7. The method of claim 1, wherein the attribute included at an adaptation set level is a sample aspect ratio of a video media component type.

8. The method of claim 1, wherein the attribute included at a representation level is an audioSampleRate, wherein the audioSampleRate specifies a sampling rate of an audio media component type.

9. The method of claim 1, wherein the element included at a representation level is an AudioChannelConfiguration, wherein the AudioChannelConfiguration specifies an audio channel configuration of an audio media component type.

10. The method of claim 1, wherein the attribute included at a representation level is a sample aspect ratio of a video media component type.

11. 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, the period, the adaptation set, the representation or the segments includes one or more attributes or elements, and,

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

12. The method of claim 11, wherein the attribute included at an MPD level is a maxSegmentDuration, wherein the maxSegmentDuration is a maximum duration of a segment in a representation.

13. The method of claim 11, wherein the element included at an adaptation set level is an Accessibility, wherein the Accessibility specifies information on an accessibility scheme.

14. The method of claim 11, wherein the attribute included at an adaptation set level is an audioSampleRate, wherein the audioSampleRate specifies a sampling rate of an audio media component type.

15. The method of claim 11, wherein the element included at an adaptation set level is an AudioChannelConfiguration, wherein the AudioChannelConfiguration specifies an audio channel configuration of an audio media component type.

16. The method of claim 11, wherein the attribute included at an adaptation set level is a contentType, wherein the contentType specifies a type of a media content component.

17. The method of claim 11, wherein the attribute included at an adaptation set level is a sample aspect ratio of a video media component type.

18. The method of claim 11, wherein the attribute included at a representation level is an audioSampleRate, wherein the audioSampleRate specifies a sampling rate of an audio media component type.

19. The method of claim 11, wherein the element included at a representation level is an AudioChannelConfiguration, wherein the AudioChannelConfiguration specifies an audio channel configuration of an audio media component type.

20. The method of claim 11, wherein the attribute included at a representation level includes a sample aspect ratio of a video media component type.

21. 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 SegmentBase element.

22. The method of claim 21, wherein the SegmentBase element is included at a period level.

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

24. The method of claim 21, wherein the SegmentBase element is included at a representation level.

25. 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 SegmentTemplate element.

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

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

28. The method of claim 25, wherein the SegmentTemplate 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.
