Signaling three-dimensional video information in communication networks
Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for signaling stereoscopic three-dimensional video content capabilities of a device in a communications network. Other embodiments may be described and claimed.
1. One or more non-transitory computer-readable media having instructions, stored thereon, that when executed cause a device to:
obtain a Third Generation Partnership (3GP)-Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH) profile associated with a user equipment (UE) of a wireless communication network, the 3GP-DASH profile to indicate one or more restrictions associated with stereoscopic three-dimensional (3-D) video content supported by the UE;
identify a first media presentation that complies with the obtained 3GP-DASH profile and is available for delivery to the UE;
obtain a media presentation description (MPD) that includes information associated with the identified first media presentation and information associated with a second media presentation that does not comply with the obtained 3GP-DASH profile;
modify, based on the obtained 3GP-DASH profile, the MPD to exclude the information associated with the second media presentation that does not comply with the obtained 3GP-DASH profile; and
transmit the modified MPD to the UE.
2. The one or more media of claim 1 , wherein the 3GP-DASH profile is a multiview stereoscopic 3D video profile to indicate that the UE supports multiview stereoscopic 3D video content that includes a base view and a non-base view that are temporally interleaved.
3. The one or more media of claim 1 , wherein the 3GP-DASH profile is a frame-packed stereoscopic 3D video profile to indicate that the UE supports frame-packed 3D video content that includes a base view and a non-base view packed in a same frame.
4. The one or more media of claim 3 , wherein the instructions, when executed, further cause the device to include a frame packing element in the modified MPD to indicate a type of frame packing format used for DASH delivery of the media presentation.
5. The one or more media of claim 4 , wherein the frame packing element indicates that the type of frame packing format used is a vertical interleaving frame compatible packing format, a horizontal interleaving frame compatible packing format, a side-by-side frame compatible packing format, a top-bottom frame compatible packing format, or a checkerboard frame compatible packing format.
6. The one or more media of claim 1 , wherein the modified MPD includes one or more attributes associated with individual DASH representations of the first media presentation, wherein the individual DASH representations include DASH representations associated with different time periods of the first media presentation.
7. The one or more media of claim 6 , wherein the modified MPD includes attributes associated with DASH representations of the first media presentation that comply with the 3GP-DASH profile and excludes attributes associated with one or more representations of the first media presentation that do not comply with the 3GP-DASH profile.
8. The one or more media of claim 1 , wherein the instructions, when executed, further cause the device to:
obtain a hypertext transfer protocol (HTTP) GET or partial GET request, transmitted by the UE, for a DASH representation associated with the first media presentation; and
send, in response to the HTTP GET or partial GET request, the DASH representation to the UE.
9. The one or more media of claim 8 , wherein DASH representation is sent to the UE via a multimedia broadcast and multicast service (MBMS).
10. The one or more media of claim 1 , wherein the 3GP-DASH profile is obtained from a device profile server.
