Telepresence applications try to provide a "being there" experience for conversational video conferencing. Often, this telepresence application is described as "immersive telepresence" in order to distinguish it from traditional video conferencing and from other forms of remote presence not related to conversational video conferencing, such as avatars and robots. The salient characteristics of telepresence are often described as: being actual sized, providing immersive video, preserving interpersonal interaction, and allowing non-verbal communication.

Use Cases for Telepresence Multistreams
Telepresence conferencing systems seek to create an environment that gives users (or user groups) that are not co-located a feeling of co- located presence through multimedia communication that includes at least audio and video signals of high fidelity. A number of techniques for handling audio and video streams are used to create this experience. When these techniques are not similar, interoperability between different systems is difficult at best, and often not possible. Conveying information about the relationships between multiple streams of media would enable senders and receivers to make choices to allow telepresence systems to interwork. This memo describes the most typical and important use cases for sending multiple streams in a telepresence conference.
