Preferably, Video coding adopts H.264 standard in described video/speech processing module, and speech coding adopts G.729/G.71 1 standard.
Preferably, the data that source node is processed video/voice module in the described real-time control module are carried out RTP and IP encapsulation.
The present invention compared with prior art, its remarkable advantage is:
1. Ad Hoc network is a kind of distributed mobile radio network, and it does not rely on fixing basic communications facility, does not have Centroid, has self organization ability, and survivability is strong, and each node in the network is equal, and has the function that E-Packets.Can avoid in the impaired problem that affects communication efficiency of some emergency networks.
2. by video communication, can vividly represent picture, make communication efficiency more lively.
3. can save communications cost based on Ad Hoc network.
