Abstract
Multiple keys are distributed to multiple clients. The keys provide access to media content. A group of clients are identified to receive substituted media content during a predetermined time period. Modified keys are generated that identify the substituted media content and the predetermined time period. The modified keys are distributed to the group of clients. The modified keys cause the group of clients to receive the substituted media content during the predetermined time period.
