Abstract: A computer implemented method and apparatus for avoiding license storming during an unplanned regional blackout. The method comprises generating a leaf license for each geographic region of a plurality of geographic regions in a broadcast area, wherein each leaf license includes a first content encryption key for decrypting media content associated with the leaf license, and where each leaf license is bound to a root license for each geographic region in the plurality of geographic regions; and generating, in response to a blackout event, a new leaf license for each geographic region of the plurality of geographic regions that are located outside of a blackout area, wherein each new leaf license includes a second content encryption key different from the first content encryption key for decrypting protected media content, and wherein each new leaf license remains bound to the root license for each geographic region in the plurality of geographic regions.

Abstract: Systems and methods are provided for converting live streaming content or other streaming content to video-on-demand streaming content. In one embodiment, a stream conversion application receives a request to access electronic content from a target stream, such as a live stream. The request identifies the live stream. The request includes at least one time code specifying a start time for accessing electronic content in the live stream. The stream conversion application obtains the at least one time code from the request. The stream conversion application retrieves content segments from the live stream based on the at least one time code during or after publication of the live stream. The content segments include the requested electronic content from the live stream. The stream conversion application generates a video-on-demand stream by combining the content segments. The stream conversion application provides access to the video-on-demand stream.
