Control Program for Multimedia Network Workstations

       This article discloses a method to enable users on a
network to share multimedia formation (i.e., audio, video).  In
particular, it describes a control program that allows a workstation
to function simultaneously as both server and client-terminal.

      The figure illustrates the inter-relationships of the
workstation functions in a multimedia network system.
1.   Control - This core function provides the multi-tasking
capabilities required to manage interactive communications between
network and local-request for interactive control of multimedia
resources attached to the workstation.  It is this function that
handles the interrupts and coordinates the other functions.
2.   Terminal - This function controls the local user interfaces,
such as the keyboard, monitor, and pointing devices.  Input/Output
from local or remote sessions are managed by this function.
3.   Application (session 1 through n) - This function provides the
interface between the Control function and any specific application.
Each application resides in a partition (session) that is assigned to
a specific user.  Multiple application sessions can operate
simultaneously.
4.   Communication (session 1 through n) - This function provides the
interface between the Control function and the communications
sessions.  All communications from the network, the terminal session,
application, and attached multimedia sources are managed by the
Communication function.
