Abstract

The Multi-Session Video Controller (MSVC) approach defines a centralized computer-based video broadcast management system to off-load the user's workstations and Local Area Network (LAN) support systems from having to deal with the intricacies of delivery and management of large quantities of diverse Audio/Video (A/V) information.

Multi-Session Video Broadcast Control System

      The Multi-Session Video Controller (MSVC) approach defines a
centralized computer-based video broadcast management system to
off-load the user's workstations and Local Area Network (LAN) support
systems from having to deal with the intricacies of delivery and
management of large quantities of diverse Audio/Video (A/V)
information.

      The MSVC solution ultimately provides the end-user with a
simple menu system for selecting a variety of video segments without
burdening the user's workstation or LAN processing environment with
the tasks of organizing, controlling and managing A/V information and
its distribution.  The result is 'A/V Information on Demand' and the
requisite video played on the desktop computer without a sacrifice in
the end-user's computational power.

      To achieve independence from, and reliance on the workstation,
the MSVC integrates the following components into a system solution
that is transparent to the Workstation and the end-user.  The
components are as follows:
  1.  MSVC Host System
  2.  A/V Database Repository
  3.  A/V Video Players
  4.  A/V Switching System
  5.  A/V Transport Network

      At the heart of the the MSVC system is the A/V database
repository with a set of Application Programming Interfaces (APIs)
and various Audio/Video (A/V) hardware components for managing the
A/V storage, their information access characteristics, and the
transparent delivery of the real-time A/V broadcast signals to
multiple users display screens independent of the data communications
channel connecting the client and server machines.

      A shared A/V database repository is defined to act as an
intelligent controller under the direction of client workstation
programs.  The function of the data repository is to store A/V
segment location information and user preferences for playback and
viewing.  Client workstations make requests for A/V segment playbacks
and the A/V database is used to initiate the playback at the correct
time, and to the correct viewing audience.  These viewing stations
may be any combinations of personal computers, televisions, cable TV
boxes, and overhead display screens.

      The A/V database repository can act independent of the end
user's computer requesting the playback and operates transparently to
the unique type and delivery method required for any given
audio/video segment.  This allows full support of analog A/V
equipment
as direct-access devices that support broadcast to groups of users.

      This invention supplies the following basic functions
associated with supporting multi-user requirements in a collaborative
distributive multi-media computing environment that exists within all
businesses and related work institutions:
  o  Automated Control of A/V Information Flow
  o  Operational Transparency of Media
  o  Management of A/V Informational Movement
  o  Non-Disruptive to Existi...
