Audio and video anti-weak network transmission method and system

Abstract

The invention discloses an audio and video anti-weak network transmission method and system. The system comprises a sending end, a receiving end and a server. The sending end comprises a data coding unit, an intelligent sending unit and a backup data unit; the sending end establishes a network state model according to the real-time data statistical feedback of the receiving end, dynamically adjusts data coding and data sending strategies according to the network state model, so that the data coding strategies and the data sending strategies are more intelligent, meanwhile, rapid correction is performed according to the real-time feedback of the receiving end, the self-learning capability is achieved, and the user experience is improved. Weak network data transmission under a complex network condition can be adapted; by deleting the successfully sent backup data, the utilization rate of the storage space is increased, and long-term occupation of the backup data is avoided; after the data is lost in the weak network environment, the number and the checking unit are set, so that the lacking data can be found in time, the targeted transmission is realized, the processing efficiency is improved, the occupied time in the re-transmission process is short, the data time delay is reduced, and the weak network resistance is improved.

Description

technical field [0001] The invention belongs to the technical field of data processing, in particular to an audio and video anti-weak network transmission method and system. Background technique [0002] The Real-time Transport Protocol (Real-timeTransportProtocol, RTP) is a network protocol for processing multimedia data streams on the Internet. It can be used to realize end-to-end real-time transmission of streaming media data in a one-to-one or one-to-many network environment. , is the basic technology of streaming media transmission widely adopted. RTP contains data and control sections that allow the receiver to reassemble received data packets. The protocol focuses on the real-time performance of data transmission, and can realize multicast and unicast data transmission. [0003] However, due to factors such as delay and volatility of network transmission, problems such as packet loss, out-of-order, and congestion are often encountered in the process of real-time dat...

Problems solved by technology

[0003] However, due to factors such as delay and volatility of network transmission, problems such as packet loss, out-of-order, and congestion are often encountered in the process of real-time data communication, which has become an important factor restricting user experience.

Therefore, there is an urgent need to propose an audio and video anti-weak network transmission method and system to solve the problem of packet loss often encountered in the process of real-time data communication
