Summary

Telepresence is an interactive audio-visual communications experience between remote locations, where users enjoy a strong sense of realism and presence between participants by optimizing a variety of attributes such as audio and video quality, eye contact, gaze awareness, body language, spatial audio, coordinated environments and natural image size. In this regard, delivering a high-level of quality of experience (QoE) is an important factor. Recommendation ITU-T G.1091 provides guidelines for achieving high QoE in telepresence services. First, a high-level description of a telepresence system is described, with an overview of important use cases. Then, specific audio and visual parameters, and other characteristics that are important from a QoE perspective are defined. Where possible, specific values for the parameters necessary to achieve high QoE are recommended, along with references to associated test methodologies.
