Abstract

The invention relates to an RTP-based anti-weak network transmission method. The method includes: backing up and storing streaming media data to be transmitted in blocks to a sending end; loading the block-blocked streaming media data into an RTP protocol header for network transmission ; Receive the streaming media data transmitted by the network, and obtain the block number of the streaming media data. If the data block of the streaming media data received does not match the streaming media data block number in the RTP protocol header, the receiving end sends a request message to The sending end; the sending end selects the data block with the same number corresponding to the backup storage according to the number of the streaming media data block, and selects the transmission channel that receives the request information first to transmit the data block to the receiving end. By sending request information to the data sender, and determining the transmission channel with the best network condition according to the time when the request information arrives at the sender, when resending lost data, the transmission channel with the best network condition is selected, and the receiver receives the complete After the data block, the data is integrated and then played.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to an RTP-based anti-weak network transmission method. 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. , the purpose is to provide time information and achieve stream synchronization, which is the basic technology of widely used streaming media transmission. [0003] RTP includes data and control parts, the former has a time stamp and a mechanism to control the synchronization characteristics of different data streams in a unified session, allowing the receiving end to reassemble the received data packets. The protocol focuses on the real-time nature of data transmission, and can realize multicast and unicast data...
