MediaSynch Issues for Computer-Supported Cooperative Work

Abstract

Computer-supported Cooperative Work (CSCW) systems are often complex distributed applications that incorporate a number of different tools working in concert to support goal- and task-driven collaborations that involve multiple sites and participants. These systems exhibit a wide variety of different system and communication architectures both within and between participating sites. In this chapter, we describe and characterize CSCW systems with respect to media synchronization requirements, identify a number of common challenges that arise as a result, and review a variety of protocol coordination techniques and mechanisms that can be brought to bear.

Definitions

Computer Supported Collaborative Work

A class of distributed multimedia systems that support goal- and task-driven collaboration among multiple participants.

Overlay Network

A logically connect group of nodes within the Internet that provide packet-based media and message transport and processing services.

Jitter

Variation in packet delay experienced in a network typically as a result of dynamic queuing delays at forwarding nodes.
