Porting multimedia applications to the Open System Environment

To migrate DOS-based courseware to the Open System Environment (OSE), process creation and communication in Posix, a portable operating-system interface, were merged with a multilevel client-server architecture. This helped identify some problems that developers are likely to face when considering any operating-system or platform migration to the OSE. The OSE reference model is reviewed, and the proposed multilevel client-server software architecture developed to fully embody the DOS model in a distributed, portable OSE is outlined. The hardware and software of the interactive video delivery system used in the OSE are described
