Apparatus and method for providing streaming content
A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include a minBufferTime attribute indicating a minimum amount of initially buffered media content. A terminal may receive content from a server before playback of the content, and may buffer the content by at least the minimum amount. The metadata may include a range attribute that designates a range of a target indicated by a Uniform Resource Locator (URL). The terminal may receive bytes designated by the range attribute from the URL, and may play back the content using the received bytes.
1. A method for providing a media content performed by one or more servers, comprising:
receiving a request for a segment of the media content based on one or more Media Presentation Descriptions (MPD), from a client; and
transmitting the media content to the client,
wherein the MPD is formalized description of a media presentation related to the media content,
wherein the MPD includes a minBufferTime attributes for each of a plurality of random access points (RAPs) of a representation, and wherein the minBufferTime attribute provides a minimum amount of initially buffered media at a beginning of a media presentation and at one of the each of the plurality of RAPs of the representation of the media presentation.
2. The method of claim 1 , wherein the MPD includes MPD type comprising at least one of attribute for availabilityStartTime, availabilityEndTime, mediaPresentationDuration, minimumUpdatePeriod and minBufferTime, timeShiftBufferDepth.
3. The method of claim 1 , wherein the MPD includes at least one of an attribute for mimeType, width and height.
4. The method of claim 1 , wherein the MPD includes attribute for minBufferSize which is defined by a data size unit or a time unit.
5. The method of claim 1 , wherein the MPD includes a bandwidth attribute that the client is assured of having enough data for continuous playout providing playout begins after a minBufferTime.
6. The method of claim 1 , wherein the MPD includes a number of consecutive segments.
7. The method of claim 6 , wherein the consecutive segments have the same bandwidth.
8. The method of claim 1 , wherein the segment includes sub-segments indexed by a segment index.
9. The method of claim 1 , wherein the MPD includes RepresentationType comprising at least one of attribute for id, bandwidth, qualityRanking, and dependencyId.
10. The method of claim 1 , wherein the MPD includes at least one of a segmentTimeline and ContentProtection.
11. A method for providing a media content performed by a client, comprising:
transmitting a request for a segment of the media content based on one or more Media Presentation Descriptions (MPD), to a server; and
receiving the media content from the server,
wherein the MPD is formalized description of a media presentation related to the media content,
wherein the MPD includes a minBufferTime attributes for each of a plurality of random access points (RAPs) of a representation, and wherein the minBufferTime attribute provides a minimum amount of initially buffered media at a beginning of a media presentation and at one of the each of the plurality of RAPs of the representation of the media presentation.
12. The method of claim 11 , wherein the MPD includes MPD type comprising at least one of attribute for availabilityStartTime, availabilityEndTime, mediaPresentationDuration, minimumUpdatePeriod and minBufferTime, time ShiftBufferDepth.
13. The method of claim 11 , wherein the MPD includes at least one of an attribute for mimeType, width and height.
14. The method of claim 11 , wherein the MPD includes attribute for minBufferSize which is defined by a data size unit or a time unit.
15. The method of claim 11 , wherein the MPD includes a bandwidth attribute that the client is assured of having enough data for continuous playout providing playout begins after a minBufferTime.
16. The method of claim 11 , wherein the MPD includes a number of consecutive segments.
17. The method of claim 11 , wherein the consecutive segments have the same bandwidth.
18. The method of claim 11 , wherein the segment includes sub-segments indexed by a segment index.
19. The method of claim 11 , wherein the MPD includes RepresentationType comprising at least one of attribute for id, bandwidth, qualityRanking, and dependencyId.
20. The method of claim 11 , wherein the MPD includes at least one of segmentTimeline and ContentProtection.
