Abstract: An audio codec uses one or more access points to broadcast or unicast a performance to a mobile digital media device that is registered and therefore is authorized to receive the performance. Prior to receiving, the mobile digital media device is authenticated by replying to an RFID query from one or more access points. If the mobile digital media device is registered, a secure key is sent to the mobile digital media device. The mobile digital media device uses the secure key to decrypt music being broadcasted or unicasted to receive the distribution of the live performances in the music venue.
