A system instructs that a first carrier signal that is modulated with a first digital media stream be sent to a first receiver, where the first digital media stream uses a first bandwidth. The system receives a second request from a second receiver to send a second digital media stream, where second digital media stream uses a second bandwidth that is greater than the first bandwidth, and determines that transmitting the second digital media stream will require use of the first bandwidth. The system instructs that a second carrier signal be modulated with the first digital media stream and sent to the first television receiver, and sends to the first television receiver an identifier of the second carrier signal as carrying the first digital media stream. The system also instructs that the first carrier signal be modulated with the second digital media stream and sent to the second television receiver, and sends to the second television receiver an identifier of the first carrier signal as carrying the second digital media stream.
