Abstract

Various embodiments include systems and methods for providing an immersive three-dimensional group session. Various embodiments include methods and devices for signaling a description of a scene with media components potentially coming from different parties. In various aspects, a scene graph may be signaled through a session description protocol (SDP) during a session initiation protocol (SIP) session setup. In various embodiments, the scene graph may include respective graphical output nodes assigned to be controlled by each of the plurality of participant computing devices in an immersive three-dimensional group session.

Dependent claims

A method performed by a processor of a wireless device that is one of a plurality of participant computing devices operating in an immersive three-dimensional group session, comprising:

receiving a scene graph for an immersive three-dimensional group session, wherein the scene graph indicates that at least an own graphical output node is controlled by the wireless device and indicates that respective other graphical output nodes are controlled by each of the other of the plurality of participant computing devices;
controlling components of the own graphical output node relative to a three-dimensional space of the immersive three-dimensional group session;
sending the components of the own graphical output node in a first media stream to the other of the plurality of participant computing devices;
receiving components of the other graphical output nodes in media streams from each of the other of the plurality of participant computing devices;
and
rendering the immersive three-dimensional group session on a display of the wireless device based at least in part on the components of the own graphical output node and the components of the other graphical output nodes.

3 more elements

A wireless device, comprising:

a display;
and
a processor coupled to the display, the processor configured with processor-executable instructions to:
receive a scene graph for an immersive three-dimensional group session, wherein the scene graph indicates that at least an own graphical output node is controlled by the wireless device and indicates that respective other graphical output nodes are controlled by each of a plurality of participant computing devices;
control components of the own graphical output node relative to a three-dimensional space of the immersive three-dimensional group session;
send the components of the own graphical output node in a first media stream to the other of the plurality of participant computing devices;
receive components of the other graphical output nodes in media streams from each of the other of the plurality of participant computing devices;
and
render the immersive three-dimensional group session on the display of the wireless device based at least in part on the components of the own graphical output node and the components of the other graphical output nodes.

6 more elements

A non-transitory processor readable medium having stored thereon processor-executable instructions configured to cause a processor of a wireless device to perform operations comprising:

receiving a scene graph for an immersive three-dimensional group session, wherein the scene graph indicates that at least an own graphical output node is controlled by the wireless device and indicates that respective other graphical output nodes are controlled by each of a plurality of participant computing devices;
controlling components of the own graphical output node relative to a three-dimensional space of the immersive three-dimensional group session;
sending the components of the own graphical output node in a first media stream to the other of the plurality of participant computing devices;
receiving components of the other graphical output nodes in media streams from each of the other of the plurality of participant computing devices;
and
rendering the immersive three-dimensional group session on a display of the wireless device based at least in part on the components of the own graphical output node and the components of the other graphical output nodes.

3 more elements

A wireless device, comprising:

means for receiving a scene graph for an immersive three-dimensional group session, wherein the scene graph indicates that at least an own graphical output node is controlled by the wireless device and indicates that respective other graphical output nodes are controlled by each of a plurality of participant computing devices;
means for controlling components of the own graphical output node relative to a three-dimensional space of the immersive three-dimensional group session;
means for sending the components of the own graphical output node in a first media stream to the other of the plurality of participant computing devices;
means for receiving components of the other graphical output nodes in media streams from each of the other of the plurality of participant computing devices;
and
means for rendering the immersive three-dimensional group session on a display of the wireless device based at least in part on the components of the own graphical output node and the components of the other graphical output nodes.
