Abstract:
This invention provides a method and a system for transmitting an encrypted control message based on the mobile multimedia broadcast. The said method includes: encapsulating the media data of the program and the encrypted control message in the multiplex sub-frames of the multiplex frame; and setting the encrypted control message identifier in the header of multiplex sub-frames for indicating whether the encrypted control message is included in the multiplex sub-frames. The mobile multimedia system sends the media data and the encrypted control message out through the multiplex frame.
