Secure streaming of digital audio/visual content |
摘要 |
A method and apparatus for secure streaming of digital audio/visual content is disclosed. Secure streaming provides protection against unauthorized use of the digital content. Authorization and integrity checks are performed by a client or playback device on a set of data associated with digital content to be played. The set of data includes authorization and integrity information for content to be received from the source. Streamed content is received from the source by the playback device. The streamed content is intermittently checked for authorization and integrity. If the check is passed, playback continues; otherwise playback is halted. |
