Publication number: 20120014456Abstract: In general, techniques are described for determining a vision-based quality metric for three-dimensional (3D) video. A device (12, 14) comprising a 3D analysis unit (24, 48) may implement these techniques to compute a 3D objective metric (36, 60). The 3D analysis unit (24, 48) estimates an ideal depth map (62, 70) that would generate a distortion limited image view using DIBR-based 3D video data (34) and then derives one or more distortion metrics (64, 72) based on quantitative comparison of the ideal depth map (62, 70) and a depth map (28, 58) used in the generation of the DIBR-based 3D video data (34). Based on the derived one or more distortion metrics (64, 72), the 3D analysis unit (24, 48) computes the objective metric (36, 60) to quantify visual quality of DIBR-based video data (34). The 3D objective metric (36, 60) may be used to alter or otherwise adjust depth estimation and encoding/decoding parameters to correct for expected visual discomfort.Type: ApplicationFiled: April 26, 2011Publication date: January 19, 2012Applicant: QUALCOMM IncorporatedInventors: Judit Martinez Bauza, Mashhour M.

Publication number: 20110032329Abstract: In general, techniques are described for transforming video data in accordance with a three dimensional (3D) input format. As one example, an apparatus, such as a mobile or portable device, that includes a transformation module, a parameter discovery module and at least one interface implements the techniques. The parameter discovery module determines an input format supported by a 3D display device. The parameter discover module then configures the transformation module to transform two-dimensional (2D) video data into 3D video data so as to generate the 3D video data in accordance with the determined input format. The at least one interface receives 2D video data. The transformation module transforms the 2D video data to 3D video data so that the 3D video data complies with the determined input format. In this manner, the apparatus implements the techniques to transform video data in accordance with a determined 3D input format.Type: ApplicationFiled: May 13, 2010Publication date: February 10, 2011Applicant: QUALCOMM IncorporatedInventors: Judit Martinez Bauza, Vijayalakshmi R.

Publication number: 20110032334Abstract: In general, techniques are described for preparing video data in accordance with a wireless display protocol. For example, a portable device comprising a module to store video data, a wireless display host module and a wireless interface may implement the techniques of this disclosure. The wireless display host module determines one or more display parameters of a three-dimensional (3D) display device external from the portable device and prepares the video data to generate 3D video data based on the determined display parameters. The wireless interface then wirelessly transmits the 3D video data to the external 3D display device. In this way, a portable device implements the techniques to prepare video data in accordance with a wireless display protocol.Type: ApplicationFiled: May 13, 2010Publication date: February 10, 2011Applicant: QUALCOMM IncorporatedInventors: Vijayalakshmi R.

Publication number: 20110032338Abstract: In general, techniques are described for encapsulating three dimensional video data in accordance with a transport protocol. As one example, an apparatus comprising a multimedia processing module, a transport protocol module and a wireless module implement the techniques. The multimedia processing module generates a video data segment, an audio data segment and a depth data segment of 3D video content. The transport protocol module encapsulates each of the video data, audio data and depth data segments in different ones of a plurality of packets according to a transport protocol and adds metadata to at least one of the plurality of packets for enhancing playback of the 3D video content. The wireless module transmits the packets to a 3D display device external from the apparatus.Type: ApplicationFiled: May 13, 2010Publication date: February 10, 2011Applicant: QUALCOMM IncorporatedInventors: Vijayalakshmi R.

Publication number: 20090252130Abstract: In embodiments, a one-to-one association is established between a client and a host in a wireless network, such as a wireless local area network or a wireless personal communication network. The client may be a display device. The host may be a cellular telephone. Active association corresponds to the host exclusively using a shared resource of the client. When the association is solid, requests from other hosts to establish an active association are denied. When the association is fragile, such requests are granted. In the case of a semi-solid association, a request from another host to establish an active association causes the client to generate a query to the host currently owning the active association. If the host currently owning the association grants a release, a new active association is established between the requesting host and the client. Otherwise, the request from the other host is denied.Type: ApplicationFiled: April 4, 2008Publication date: October 8, 2009Applicant: QUALCOMM IncorporatedInventors: Soham V.
