Architectural aspects of multimedia CD-I integration in UNIX / X-windows workstations

Abstract

This paper describes the integration of CD-I systems in UNqX and X-Windows/Motif workstations. It is based on results of the ESPRIT project MULTIWORKS. First a short overview of the main CD-t features is given. A description of the basic requirements for the integration of CD-I in professional workstations follows. One of the major requirements is the support of off-the-shelf CD-I titles running in a Motif window concurrent with other UNIX applications and the support of new UNIX/Motif multimedia applications, which use the CD-I player as a digital video, sound and CD-ROM sub-system. The client / server architecture and the separation and distribution of time critical multimedia API functions over both systems (UNIX WS and CD-I system) are presented in more detail with special emphasis on the critical problems concerning real-time handling. Finally some experiences with the system are described.
