Abstract: A processing device of a media server selects a media item to be provided to users via a satellite broadcast system, encrypts the media item using an encryption key to generate an encrypted media item, and transmits the encrypted media item to the satellite broadcast system via a first communication protocol. The processing device receives a request from a user device for authorization to decrypt the encrypted media item obtained by the user device via a direct connection with the satellite broadcast system. The request is received by the media server via a second communication protocol that is different from the first communication protocol. The processing device determines whether the user device is authorized to decrypt the encrypted media item, and transmits a key for decrypting the encrypted media item in response to the user device being authorized to decrypt the encrypted media item.
