Apparatus and method for providing content
A method of receiving content in a client is provided. The method may include receiving, from a server, a spatial set identifier (ID) corresponding to a tile group including at least one tile, sending, to the server, a request for first content corresponding to metadata, and receiving, from the server, the first content corresponding to the request.
1. A method of receiving content in a client, the method comprising:
receiving in the client, from a server, a spatial set identifier (ID) to identify a group of spatially related spatial objects in a full-frame video;
sending from the client, to the server, a request for a first content corresponding to the spatial set ID; and
receiving in the client, from the server, the first content corresponding to the request,
wherein the receiving of the spatial set ID comprises receiving a Spatial Relationship Description (SRD) which allows Media Presentation Description authors to express spatial relationships between spatial objects,
wherein the spatial relationship is related to a video which represents a spatial part of the full-frame video,
wherein the spatial ablest is represented by adaptation set or a sub-representation, and
wherein the SRD comprises the spatial set ID, and a horizontal position of each of the spatial objects (x), a vertical position of each of the spatial objects (y), a width of a reference space (W) and a height of the reference space (H).
2. The method of claim 1 , wherein the spatial set ID is configured to identify a tile group comprising at least one of tiles into which full-frame video is spatially divided.
3. The method of claim 2 , wherein the first content comprises a video corresponding to the tile group.
4. The method of claim 1 , wherein the spatial set ID is configured to group sets of the at least one spatial object.
5. The method of claim 1 , wherein the receiving of the spatial set ID comprises receiving metadata comprising the spatial set ID.
6. The method of claim 5 , wherein the metadata comprises a Media Presentation Description (MPD) of content.
7. The method of claim 6 , wherein the MPD comprises the Spatial Relationship Description (SRD).
8. The method of claim 1 , wherein the sending of the request comprises transmitting, to the server, a request comprising a Uniform Resource Locator (URL) corresponding to the first content.
9. The method of claim 8 , wherein the URL comprises a URL corresponding to one of the plurality of tiles into which the full-frame video is spatially divided.
10. A method of transmitting content in a server, the method comprising:
transmitting, from the server to a client, a spatial set identifier (ID) to identify a group of spatially related spatial objects in a full-frame video;
receiving in the server, from the client, a request for a first content corresponding to the spatial set ID; and
transmitting, from the server to the client, the first content corresponding to the request,
wherein the transmitting of the spatial set ID comprises transmitting a Spatial Relationship Description (SRD) which allows Media Presentation Description authors to express spatial relationships between spatial objects,
wherein the spatial relationship is related to a video which represents a spatial part of the full-frame video,
wherein the spatial object is represented by adaptation set or a sub-representation, and
wherein the SRD comprises the spatial set ID, and a horizontal position of each of the spatial objects (x), a vertical position of each of the spatial objects (y), a width of a reference space (W) and a height of the reference space (H).
11. The method of claim 10 , wherein the spatial set ID is configured to identify a tile group comprising at least one of tiles into which full-frame video is spatially divided.
12. The method of claim 11 , wherein the first content comprises a video corresponding to the tile group.
13. The method of claim 10 , wherein the spatial set ID is configured to group sets of the at least one spatial object.
14. The method of claim 10 , wherein the transmitting of the spatial set ID comprises transmitting metadata comprising the spatial set ID.
15. The method of claim 14 , wherein the metadata comprises a Media Presentation Description (MPD) of content.
16. The method of claim 15 , wherein the MPD comprises the Spatial Relationship Description (SRD).
17. The method of claim 10 , wherein the receiving of the request comprises receiving, from the client, a request comprising a Uniform Resource Locator (URL) corresponding to the first content.
18. The method of claim 17 , wherein the URL comprises a URL corresponding to one of the plurality of tiles into which the full-frame video is spatially divided.
