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 media content performed by a server, the method comprising:

receiving a request for the media content from a client based on media presentation description (MPD) with respect to the media content; and

providing a segment of media content through streaming to the client in response to the request,

wherein the 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 MPD includes group element describing each of the groups,

wherein the group element provides a summary of values of all representations within a group,

wherein the group element includes (1) ID of group, (2) minBandWidth indicating a minimum value among bandwidth attributes of all representations in the group,

(3) maxBandWidth indicating a maximum value among bandwidth attributes of all representations in the group, (4) minWidth indicating a minimum value among width attributes of all representations in the group, (5) maxWidth indicating a maximum value among width attributes of all representations in the group, (6) minHeight indicating a minimum value among height attributes of all representations in the group,

(7) maxHeight indicating a maximum value among height attributes of all representations in the group, (8) minFrameRate indicating a minimum value among frame rate attributes of all representations in the group, and (9) maxFrameRate indicating a maximum value among frame rate attributes of all representations in the group.

2. The method of claim 1, wherein the MPD includes information for view of media contents.

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

transmitting a request for the media content to a server based on media presentation description (MPD) with respect to the media content; and

receiving a segment of media content through streaming from the server in response to the request,

wherein the 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 MPD includes group element describing each of the groups,

wherein the group element provides a summary of values of all representations within a group,

wherein the group element includes (1) ID of group, (2) minBandWidth indicating a minimum value among bandwidth attributes of all representations in the group,

(3) maxBandWidth indicating a maximum value among bandwidth attributes of all representations in the group, (4) minWidth indicating a minimum value among width attributes of all representations in the group, (5) maxWidth indicating a maximum value among width attributes of all representations in the group, (6) minHeight indicating a minimum value among height attributes of all representations in the group,

(7) maxHeight indicating a maximum value among height attributes of all representations in the group, (8) minFrameRate indicating a minimum value among frame rate attributes of all representations in the group, and (9) maxFrameRate indicating a maximum value among frame rate attributes of all representations in the group.

4. The method of claim 3, wherein the MPD includes information for view of media contents.

5. A non-transitory computer readable storage medium containing program instructions for media presentation description (MPD), wherein execution of the program instructions by one or more processors of a computer system causes the one or more processors to carry out the act of providing a segment of media contents through streaming from a server to a client,

wherein the 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 MPD includes group element describing each of the groups,

wherein the group element provides a summary of values of all representations within a group,

wherein the group element includes (1) ID of group, (2) minBandWidth indicating a minimum value among bandwidth attributes of all representations in the group,

(3) maxBandWidth indicating a maximum value among bandwidth attributes of all representations in the group, (4) minWidth indicating a minimum value among width attributes of all representations in the group, (5) maxWidth indicating a maximum value among width attributes of all representations in the group, (6) minHeight indicating a minimum value among height attributes of all representations in the group,

(7) maxHeight indicating a maximum value among height attributes of all representations in the group, (8) minFrameRate indicating a minimum value among frame rate attributes of all representations in the group, and (9) maxFrameRate indicating a maximum value among frame rate attributes of all representations in the group.
