Abstract

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.

First claim

What is claimed is:

1. One or more non-transitory computer-readable media having instructions that, when executed, cause a device to:
obtain, from a device profile server, a streaming frame packing format attribute that includes a list of frame packing formats, supported by a client terminal of a wireless communication network, relevant for streaming of stereoscopic 3-D video over a transport protocol supported by a packet-switched streaming service (PSS) application on the client terminal, wherein the transport protocol is a real-time transport protocol (RTP) or a hypertext transfer protocol (HTTP);
adapt content based on the streaming frame packing format attribute;
generate a session description or metadata file to establish a streaming session based on the streaming frame packing format attribute; and
transmit the adapted content and the generated session description or metadata file to the client terminal,
wherein the list of frame packing formats includes an indication of 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, a checkerboard frame compatible packing format, or a temporal interleaving full-resolution per view packing format.

2. The one or more non-transitory computer-readable media of claim 1 , wherein the list comprises a list of one or more integer values that respectively correspond to one or more supported frame packing formats.

3. The one or more non-transitory computer-readable media of claim 2 , wherein the list of one or more integer values includes a 1 to correspond to a vertical interleaving frame compatible packing format, a 2 to correspond to a horizontal interleaving frame compatible packing format, a 3 to correspond to a side-by-side frame compatible packing format, a 4 to correspond to a top-bottom frame compatible packing format, a 0 to correspond to a checkerboard frame compatible packing format, or a 5 to correspond to a temporal interleaving full-resolution per view packing format.

4. The one or more non-transitory computer-readable media of claim 1 , wherein the transport protocol comprises an RTP.

5. The one or more non-transitory computer-readable media of claim 1 , wherein the transport protocol comprises an HTTP.

6. The one or more non-transitory computer-readable media of claim 1 , wherein the session description or metadata file is a real-time streaming protocol (RTSP) session description protocol (SDP) file or a dynamic adaptive streaming over hypertext transport protocol (DASH) media presentation description (MPD) file.

7. The one or more non-transitory computer-readable media of claim 1 , wherein content is 3-D video content and the instructions, when executed, further cause the device to:
transcode the 3-D video content or convert a format of the 3-D video content based on the streaming frame packing format attribute.

8. One or more non-transitory computer-readable media having instructions that, when executed, cause a device to:
obtain, from a device profile server, a frame packing format attribute that includes a list of one or more frame packing formats, supported by a user equipment, relevant for stereoscopic 3-D video that can be included in a 3rd Generation Partnership Project file format (3GP) file and handled by a packet-switched streaming service (PSS) application on the user equipment; and
transmit content to the user equipment based on the frame packing format attribute,
wherein the list of one or more frame packing formats includes an indication of 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, a checkerboard frame compatible packing format, or a temporal interleaving full-resolution per view packing format.

9. The one or more non-transitory computer-readable media of claim 8 , wherein the list of frame packing formats includes an indication of a side-by-side frame packing format or a top-bottom frame packing format.

10. The one or more non-transitory computer-readable media of claim 8 , wherein the list comprises a list of one or more integer values that respectively correspond to one or more frame packing formats.

11. The one or more non-transitory computer-readable media of claim 10 , wherein the list of one or more integer values includes a 3 to correspond to side-by-side frame packing format or a 4 to correspond to a top-bottom frame packing format.

12. An apparatus comprising:
a media player to decode and render stereoscopic three-dimensional (3-D) video content, wirelessly received by a mobile device, on a display of the mobile device; and
a content management module to:
determine device capability information including 3-D video codecs and a list of frame packing formats supported by the media player, wherein the list of frame packing formats includes an indication of 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, a checkerboard frame compatible packing format, or a temporal interleaving full-resolution per view packing format;
transmit one or more messages to a device profile server, the one or more messages including the device capability information;
transmit at least one message to a media server, the at least one message including a request for stereoscopic 3-D video content and any temporary adjustments on the device capability information.

13. The apparatus of claim 12 , wherein the device capability information has a 3-D format attribute that includes a format type supported by the media player.

14. The apparatus of claim 13 , wherein the format type is a frame-packing format type that corresponds to a frame compatible packing format or a full-resolution per view packing format, a simulcast format type, or a two-dimensional plus auxiliary format type.

15. The apparatus of claim 14 , wherein the format type is a frame-packing format type that is a frame compatible packing format with a value to indicate vertical interleaving, horizontal interleaving, side-by-side, top-bottom, or checkerboard.

16. The apparatus of claim 12 , wherein the 3-D video content is wirelessly received by the mobile device via a packet-switched streaming service.

17. The apparatus of claim 12 , wherein the content management module is to transmit device capability information in a session initiation protocol (SIP) SUBSCRIBE message to an Internet Protocol Multimedia Core Network subsystem during service discovery.

18. The apparatus of claim 17 , wherein, subsequent to service discovery, the content management module is to use SIP signaling to update a set of supported 3-D video codecs and formats.

19. The apparatus of claim 12 , wherein the media player is further configured to:
receive a stream including the requested stereoscopic 3-D video content, wherein the media player is further configured to receive the stream according to a dynamic adaptive streaming over hypertext transport (DASH) protocol; a packet-switched streaming (PSS) protocol; or an Internet protocol multimedia subsystem (IMS)-based PSS and multimedia broadcast/multicast services (MBMS) protocol.

20. The apparatus of claim 19 , wherein the media player is further configured to receive a session description protocol (SDP)
