Montage: Applications of Scalable Multipoint Video and Audio Using the Public Internet

摘要

This paper describes the Montage[1] scalable multipoint video system, designed for efficient generation and display of high-qualtiy, multiple resolution, multiple compressed video streams over IP based networks. We will present our experiences using the system over the public Internet for several "real-world" applications, including distance learnign, virtual theatre, and virtual collaboration. The trials were a combined effort of Beel Laboratories and the Gertrude Stein Repertory Theatre (TGSRT)[2]. For eighteen months, Bell Labs created several scenarios with educators and artists. In each instance the academic and artistic goals as well as the technical implementation was different. By conducting trials in typical environments we have gathere valuable information about the viability of high quality video over the public Internet.
