Abstract

Methods and apparatus for perform association of stored content downloaded over a network with a unique identification. In one embodiment, the content is stored locally, and the association is performed in a secure manner using network or source-specific information (e.g., the organization identification or “orgID” of the bearer network or MSO). This association is used to ensure that the content stored on the playback device can be accessed for viewing only when the playback device is connected to the same network from which the content was obtained. Use of the orgID allows the content association and protection functionality to be implemented in existing networks with only minor software changes.

Claims
