Abstract

An apparatus may include one or more radio-frequency (RF) transceivers arranged to receive multimedia content during a session over a first link from a wireless wide-area network (WWAN) and to forward information over a second link to a display device. The apparatus may further include a processor circuit communicatively coupled to the one or more RF transceivers and a video adaptation module operative on the processor circuit to gather device capability information from the display device, and to modify device capability exchange signaling to the WWAN based upon the gathered device capability information, the device capability exchange signaling to define exchange of multimedia content between the apparatus and the WWAN. Other embodiments are disclosed and claimed.

First claim

What is claimed is:

1. User Equipment (UE), comprising:
a packet based network interface to receive one or more media streams over a first link of a third generation partnership project (3GPP) network via a hypertext transfer protocol (HTTP) or a dynamic adaptive streaming over HTTP (DASH) protocol; and
a packet-switched streaming service (PSS) client to send capability information over the first link, the capability information to specify device capability attributes that describe device capabilities used to receive the one or more media streams over the first link, the device capability attributes to describe capabilities of a display device accessible via a second link of a wireless local area network, the PSS client to manage communication with the display device over the second link based upon information gathered from session level signaling with a PSS server using a session description protocol (SDP) or media presentation description (MPD).

2. The UE of claim 1 , the packet based network interface to receive a media stream via a real time streaming protocol (RTSP).

3. The UE of claim 1 , the PSS client to send capability information via a real time streaming protocol (RTSP) and a session description protocol (SDP).

4. The UE of claim 1 , the capability information including one or more of a pre-decoder buffer size, initial buffering period, decoder capability, display properties, streaming method, adaptation support information, quality of experience (QoE) support information, extended real time transport control protocol (RTCP) reporting support, fast content switching support, supported real-time transport protocol (RTP) profile information, or session description protocol (SDP) attributes.

5. The UE of claim 1 , the PSS client to send negotiate session parameters over the first link based upon the capabilities of the display device.

6. The UE of claim 5 , the session parameters including one or more of codec information, container format, decoder capabilities, video quality requirements, quality of service (QoS) parameters, transport protocols that account for characteristics of the second link, or capabilities of the display device.

7. The UE of claim 1 , comprising a radio-frequency (RF) transceiver to communicate information over the second link, the PSS client to receive attributes that describe the display device capabilities over the second link via the RF transceiver, and forward the one or more media streams over the second link via the RF transceiver.

8. The UE of claim 7 , the PSS client to perform over the second link one or more of modify session parameters, adapt video parameters, prioritize traffic over the second link, allocate resources, and optimize bandwidth allocation.

9. The UE of claim 7 , the PSS client to perform media adaptation operations based upon one or more of characteristics of the second link or capabilities of the display device.

10. The UE of claim 1 , the device capability attributes each comprising an attribute name, a permissible value, and semantics of a defined vocabulary.

11. The UE of claim 1 , comprising a touch screen display.

12. User Equipment (UE), comprising:
a processor circuit; and
a packet-switched streaming service (PSS) client for execution by the processor circuit to receive capability information for a media stream over a link of a third generation partnership project (3GPP) long term evolution (LTE) or LTE advance (LTE-A) network, the capability information to specify device capability attributes used to receive the media stream over the link, and perform temporary adjustments to the device capability attributes to describe capabilities of a display device, the PSS client to receive the media stream via a hypertext transfer protocol (HTTP) or a dynamic adaptive streaming over HTTP (DASH) protocol, and
a radio-frequency (RF) transceiver to forward the one or more media streams to the display device over a second link of a wireless local area network, and the PSS client to manage communication with the display device over the second link based upon information gathered from session level signaling with a PSS server using a session description protocol (SDP) or media presentation description (MPD).

13. The UE of claim 12 , the PSS client to receive a second media stream via a real time streaming protocol (RTSP).

14. The UE of claim 12 , the PSS client to derive, based upon characteristics of the second link and display device capability information, one or more of real-time transport control protocol (RTCP) receiver reports, real-time streaming protocol (RTSP) messages, temporary maximum media stream bit rate request (TMMBR) messages, or HTTP GET requests for DASH representations.

15. The UE of claim 12 , the PSS client to generate a quality of quality of experience (QoE) report based on reliability of transmission over the second link or characteristics of media processing performed by the display device.

16. The UE of claim 15 , the media processing to include media buffering operations or media decoding operations.

17. The UE of claim 12 , the PSS client to perform using a real time streaming protocol (RTSP) and session description protocol (SDP) protocol stack over the second link session management or device capability signaling.

18. The UE of claim 12 , comprising a touch screen display.

19. A wireless device, comprising:
a radio-frequency (RF) transceiver to receive one or more media streams from a packet-switched streaming service (PSS) server over a first link of a third generation partnership project (3GPP) long term evolution (LTE) or LTE advance (LTE-A) network via a hypertext transfer protocol (HTTP) or a dynamic adaptive streaming over HTTP (DASH) protocol;
a video adaptation module to cause capability information to be sent by the RF transceiver over the first link, the capability information to specify device capability attributes used to receive the one or more media streams over the first link, and perform temporary adjustments to the device capability attributes to describe capabilities of a display device accessible via a second link of a wireless local area network; and
