Systems for bidirectional visual communication have been available for a long time, but were rarely used in daily private or business life. However, in the last years the user acceptance of visual communication services has increased significantly. Not only for consumers but especially for businesses and global companies, videotelephony and videoconferencing have become more important, driven by the requirements of reducing travel cost, travel time, and emissions. The 3GPP IP Multimedia Subsystem (IMS) is a standardized framework for deploying multimedia services, such as telephony, messaging and presence. This article discusses advanced visual communication services and how such services and the underlying technical components can be realized. We focus on high quality videoconferencing, using high-definition video and full-band audio.
