Section Three: Selecting a Client/Server System
[You can view/print this section with Acrobat Reader.]

Digital audio and video exist today in a state of paradox: demand for digital files in audiovisual formats is great; mature standards supporting digital video and audio on optical media (CD, CD-ROM and DVD) and broadcast systems (satellite, TV, HDTV) are widely available. Systems to support digital video, however, while offering exciting functionalities and tremendous potential, are still emerging rather than proven, particularly in critical areas of interoperability and adherence to open standards. It is possible to select the right system for your needs, among many good, fairly solid offerings, but more care must be taken than in the selection of client/server systems to support electronic text. In early 1999, selecting the right digital video client/server system to grow with your developing needs is still a risky venture, requiring careful planning and needs assessment.




Applications: Northwestern University New Media Center

The Northwestern University New Media Center (NUNMC) works with faculty, students, and staff within the University to foster the use, development, and integration of new media in higher education. Among their projects are a Guided Tour of the Marjorie I. Mitchell Multimedia Center, which uses RealAudio Synchronized Multimedia to combine a slideshow presentation with a streamed audio narration, and VideoPaths to The Challenge of Democracy, a multimedia enhanced learning environment incorporating 80+ minutes of MPEG video, encoded at 1.2Mbps, and delivered via an IBM VideoCharger server.
