Abstract

The present invention provides a method and corresponding device of, in broadcasting and TV network and communication network, providing audio/video signal playable in communication network. With the aid of the present invention, security controlling means in communication network encrypts the plaintext of control word and return the encrypted version to the broadcasting and TV network. Consequently, the broadcasting and TV network multiplexes the encrypted control word and scrambled audio/video signal, and broadcasts the multiplexed signal to mobile terminals in said communication network. Hence, mobile phone TV services can be protected onground broadcasting and TV network platform.
