The mechanisms of network transport and its management were put forward on the basis of analyzing the characteristics of multi transport. A set of data packet format which meets the requirements of the system was designed and the model of the receiving queues was described. The whole structure of the system and the primary functions acted by each unit were given. The theory of decoding in real time was expounded, and the structures and realization methods of the decoders were also described. The ideas of saving in sections in real time and querying were expressed. Tests and comparisons were made between the performances of systems.
