Abstract
The invention discloses a method for performing joint broadcast by using a radio and television network and a mobile data network. The method comprises the following steps that: 1, an analogue video signal is transmitted to a multicast video control device by a coaxial cable; 2, the multicast video control device converts the analogue video signal into a digital video signal; 3, the multicast video control device transmits the digital video signal by a wireless fidelity (WI-FI) wireless module; 4, the multicast video control device constructs child nodes and leaf nodes according to link state information; 5, the multicast video control device regularly transmits specific information requirement responses to the child nodes and the leaf nodes; and 6, a currently adopted leaf node accesses the child node, and a multicast module in the multicast video control device makes a user select information, and transmits digital video data to intelligent handheld equipment user after the information selected by the user arrives at the multicast module. By the method provided by the invention, the playing of videos within a certain range on mobile equipment can be realized; and the method has a high commercial value.
