Abstract

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata of the content may be efficiently divided for a purpose of use of a terminal based on general media information or specific media information, and may be transmitted to the terminal. A group may include one or more representations of content. The metadata may include a group element, and the group element may provide a summary of attributes of one or more representations included in the group.

Claims

1. A method of providing content performed by a client, the method comprising:

receiving, from a server, a specific Media Presentation Description (MPD) suitable for the client, the specific MPD comprising descriptions of representations of the content suitable for the client;

selecting an appropriate representation from among the representations in the specific MPD based on the descriptions of the representations; and

requesting the server to transmit content corresponding to the selected representation,

wherein the specific MPD includes one or more periods,

wherein the period includes one or more groups,

wherein the group includes one or more representations,

wherein the representation includes one or more segments,

wherein the specific MPD includes one or more group elements for each of the groups, and

wherein the group element is related to a summary of values of attributes of all representations within the group.

2. The method of claim 1, wherein the specific MPD is selected among multiple specific MPDs.

3. The method of claim 1, wherein the representations in the specific MPD are specific to a predetermined category of a terminal.

4. The method of claim 3, wherein the terminal is one of a high-definition television (HDTV), a personal computer, and a mobile phone.

5. The method of claim 1, wherein the group element is related to a summary of values of attributes of all representations within the group, wherein the attribute of the group includes at least one of (i) minBandWidth for indicating a minimum value among bandwidth attributes of all representations in the group, (ii) maxBandWidth for indicating a maximum value among bandwidth attributes of all representations in a group, (iii) minWidth for indicating a minimum value among horizontal resolution attributes of all representations in a group, (iv) maxWidth for indicating a maximum value among horizontal resolution attributes of all representations in a group, (v) minHeight for indicating a minimum value among minimum height attributes of all representations in a group, (vi) maxHeight for indicating a maximum value among maximum height attributes of all representations in a group, (vii) minFrameRate for indicating a minimum value among frame rate attributes of all representations in a group, and (viii) maxFrameRate for indicating a maximum value among frame rate attributes of all representations in a group.

12. The method of claim 1, wherein the specific MPD is based on at least one of specific attributes,

wherein the specific attributes are related to information of the client or a user.

13. The method of claim 12, the specific attributes include at least one of (i) capability, (ii) preference, (iii) minBand, (iv) maxBand, (v) averBand, (vi) width, (vii) height, (viii) framerate, (ix) lang, (x) mime, (xi) a view identifier (ID) of a multi-view video, and (xii) a complexity or quality of audio (xiii) a complexity or quality of video.

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

transmitting, to a client, a specific Media Presentation Description (MPD) suitable for the client, the specific MPD comprising descriptions of representations suitable for the client;

receiving, from the client, a request for content corresponding to a representation in the specific MPD selected by the client, and

transmitting the content corresponding to the selected representation in the specific MPD to the client,

wherein the specific MPD includes one or more periods,

wherein the period includes one or more groups,

wherein the group includes one or more representations,

wherein the representation includes one or more segments.

wherein the specific MPD includes one or more group elements for each of the groups, and

wherein the group element is related to a summary of values of attributes of all representations within the group.

7. The method of claim 6, wherein the specific MPD is selected among multiple specific MPDs that are generated in advance.

8. The method of claim 6, wherein the representations in the specific MPD are specific to a predetermined category of a terminal.

9. The method of claim 8, wherein the terminal is one of a high-definition television (HDTV), a personal computer, and a mobile phone.

10. The method of claim 8, wherein the group element is related to a summary of values of attributes of all representations within the group, wherein the attribute of the group includes at least one of (i) minBandwidth for indicating a minimum value among bandwidth attributes of all representations in the group, (ii) maxBandwidth for indicating a maximum value among bandwidth attributes of all representations in a group, (iii) minWidth for indicating a minimum value among horizontal resolution attributes of all representations in a group, (iv) maxWidth for indicating a maximum value among horizontal resolution attributes of all representations in a group, (v) minHeight for indicating a minimum value among minimum height attributes of all representations in a group, (vi) maxHeight for indicating a maximum value among maximum height attributes of all representations in a group, (vii) minFrameRate for indicating a minimum value among frame rate attributes of all representations in a group, and (viii) maxFrameRate for indicating a maximum value among frame rate attributes of all representations in a group.

14. The method of claim 6, wherein the specific MPD is based on at least one of specific attributes,

wherein the specific attributes are related to information of the client or a user.

15. The method of claim 14, the specific attributes include at least one of (i) capability, (ii) preference, (iii) minBand, (iv) maxBand, (v) averBand, (vi) width, (vii) height, (viii) framerate, (ix) lang, (x) mime, (xi) a view identifier (ID) of a multi-view video, and (xii) a complexity or quality of audio (xiii) a complexity or quality of video.

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

transmitting, to a client, a metadata suitable for the client, the metadata provides descriptive information that enable the client to select a structured collection of one or more media component of the content;

receiving, from the client, a request for content corresponding to a media component selected based on the media component by the client, and

transmitting the content corresponding to the selected media component to the client,

wherein the metadata includes a summary of values of attributes of all media component.
