Wireless device, signaling method describing scene with media components that can come from different sides, and invariable media read by processor

Abstract

The invention's proposed solutions include systems and methods for providing integrated three-way group sessions. The various solutions include methods and devices for signaling scene descriptions with media components that may come from different parties. In various respects, scene descriptions can be signaled via the session description protocol (SDP) during session setup of the session initiation protocol (SIP). Depending on the different scenarios, the branch graph may include corresponding graphical output nodes assigned to be controlled by each of the many computing devices participating in the integrated three-dimensional group session. Additionally, the invariant means readable by the processor are also revealed.
