METHOD AND APPARATUS FOR AVOIDING LICENSE STORMING DURING AN UNPLANNED REGIONAL BLACKOUT

摘要

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.
