Title: Interactive Media on Demand: Generic Recording and Replay ofInteractive Media Streams
Published: Proceedings of ACM Multimedia 2001 (Technical Demonstration), , pp. 593-594, Ottawa, Canada, October 2001
Keyword(s): Multicast, Interactive Media, Recording, Streaming
Abstract: In this demonstration we present a generic recording service for distributed interactive media, i.e., media which allow a distributed group of users to interact with the medium itself. Typical examples of this media class are shared whiteboard systems, distributed virtual environments and networked computer games. By defining an abstract model and an application level protocol we were able to develop the first generic recording service for arbitrary distributed interactive media. This service is called Interactive Media on Demand (IMoD), and it is able to record and replay all applications that are based on the RTP/I protocol. In particular it allows random access to the recorded media streams. We demonstrate the IMoD system by recording and replaying a shared whiteboard, a networked computer game and a 3D telecooperation application.
