Abstract

With the advent of electronic mediums to distribute multimedia presentations there is a need to control the manipulation of these presentations. Current distribution systems do not allow restriction mechanisms for video presentations to a particular machine. Moreover, no mechanism is provided to limit the number of times a presentation can be viewed. Enterprises desire a mechanism to enforce and electronically control contractual obligations for media presentations, e.g., copyright and licensing agreements. A mechanism is desired whereby an enterprise can remotely control the frequency at which a multimedia object is presented. It should be noted that the term view is used in the general sense for objects which can be seen or heard.

Remote Consensual Control of Multimedia Presentations

      With the advent of electronic mediums to distribute multimedia
presentations there is a need to control the manipulation of these
presentations.  Current distribution systems do not allow restriction
mechanisms for video presentations to a particular machine.
Moreover, no mechanism is provided to limit the number of times a
presentation can be viewed.  Enterprises desire a mechanism to
enforce and electronically control contractual obligations for media
presentations, e.g., copyright and licensing agreements.  A mechanism
is desired whereby an enterprise can remotely control the frequency
at which a multimedia object is presented.  It should be noted that
the term view is used in the general sense for objects which can be
seen or heard.

      This article describes a mechanism whereby the originator of a
distributed multimedia object can remotely control viewing access
dynamically through a token exchange mechanism.  This mechanism
allows an enterprise to associate a consensual transaction to a
video/audio presentation.  Viewing frequency can be controlled by the
originator after distributing the object.  Authorizing users can
further constrain, dynamically, presentations to designated computer
systems.  Note: This problem differs from the central control of
"playing" an object.  Prior documents describe a single presentation
to be played and to control viewing access to users, similar to
pay-per-view cable methods.

      This method utilizes a generalized data structured format by
which consensual fields are associated with the media presentation.
These fields define consensual attributes which are accessed and
control via remote authorization services of the originating
enterprise.  Although not exhaustive, the following attributes under
an encryption algorithm are distributed as a component of the media
object:

o   Total Frequency - this attribute allows an originating enterprise
    to control the total number of times the media presentation can
    be viewed by a user or enterprise.
o   Member List - this attribute allows an enterprise to remotely
    associate the viewing capabilities of a presentation to specific

    machines, i.e., change viewing permission dynamically across a
    network to differing machines.

      These attributes are manipulated by a Consen...
