Problems solved by technology

[0003] Despite the rapid development of wireless networks, wireless video transmission still faces enormous challenges, such as the dynamics and heterogeneity of wireless networks, high error rates, unpredictability of transmission links, and the impact of highly compressed video streams on transmission. The characteristics of being very sensitive to errors have a great impact on the quality of wireless video transmission

[0004] At present, layered network protocols are used, and layers communicate in a fixed way. Although they also have certain adaptive capabilities, such as using adaptive signal processing to adjust channel parameters, update routing tables, and change traffic loads, etc., these The adjustment update is irrelevant to the network level, and there is no information exchange between layers. In the changing wireless mobile environment, this fixed communication method cannot effectively use the limited spectrum and power resources, and cannot be used well. Meet the requirements of different businesses for Quality of Service (QoS)

In addition, although this method can use a variety of networks to transmit data, users need to manually configure and switch networks according to network conditions, and there are interruptions and delays

[0005] In the process of realizing the present invention, the inventor found that there are at least defects such as low reliability, poor real-time performance and large amount of manual labor in the prior art
