A general framework and communication protocol for the transmission of interactive media with real-time characteristics

In this paper we present a general framework for the transmission of interactive media with real-time characteristics, i.e. media involving user interaction. By identifying and supporting the common aspects of interactive media the framework allows the development of generic services for distributed, collaborative work involving the transmission of interactive media. Derived from the experience gained with audio and video transmission using the Real-Time Transport Protocol (RTP), we define a new RTP profile for interactive media.
