Abstract

Provided is a network environment video signal management facility which increases the likelihood users are not deteriorating network performance. Large (host) systems serve as centralized distribution points for a variety of signals. A method is needed for managing networked broadcasts so multiple users can share a single signal rather than allocate their own set of duplicated resources. Specifically, a networked environment, wherein users may view videos or television broadcasts from a video signal server, requires a method for coordinating multiple accesses of the same videos or signals at substantially the same time so as to prevent managing multiple sets of resources in order to grant the requests of a multiplicity of users.

Method for Communicating in Progress Broadcast to Interested Parties

      Provided is a network environment video signal management
facility which increases the likelihood users are not deteriorating
network performance.  Large (host) systems serve as centralized
distribution points for a variety of signals.  A method is needed for
managing networked broadcasts so multiple users can share a single
signal rather than allocate their own set of duplicated resources.
Specifically, a networked environment, wherein users may view videos
or television broadcasts from a video signal server, requires a
method for coordinating multiple accesses of the same videos or
signals at substantially the same time so as to prevent managing
multiple sets of resources in order to grant the requests of a
multiplicity of users.

      Upon user request to view a video from a server library or a
television signal from a continually monitored signal, the user is
automatically prompted if the video or signal is already in progress
of being viewed by one or more other users.  The prompt will indicate
who is watching the requested video or signal and what time each user
started to watch it.  The requesting user then has an option to
become an additional client of a "show" already in progress.  This
allows eliminating a user from allocating a duplicated set of
resources in order to observe the same "show" one or more other users
are already watching.  A single buffer of video data may then be
transmitted to multiple requesters rather than each requester having
his own buffer and input/output task to manage the "show"....
