Problems solved by technology

If the file decoding fails, the server needs to rotate multiple times to realize the retransmission of the file, but the repeated reception of the received part of the file cannot be avoided, resulting in the generation of redundant data

Abstract

The present application provides a file transmission method based on a converged transmission system, the method comprising: acquiring the file encoding symbol of the file to be pushed and the file description information corresponding to the file, and storing the file description information and the file description information to be pushed The file coding symbol of the said file is encapsulated into a fusion transport stream and sent to the terminal; after receiving the file source symbol retransmission request sent by the terminal, the file source symbol of the requested file is reacquired, and the file source symbol of the file is The symbol is encapsulated as a file source symbol retransmission response and sent to the terminal. In the file transmission method of the present application, after the terminal fails to decode the file encoding symbol of the file, it sends a file source symbol retransmission request to the server side, and the server encapsulates the requested file source symbol into a file source symbol retransmission response and sends it to the terminal to achieve The terminal decodes all files to ensure the reliability of file transmission.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a file transfer method based on a converged transfer system. Background technique [0002] The satellite mobile broadcasting system uses geosynchronous orbit satellites to provide multimedia information services including audio, video, data, etc. for signal coverage areas (including one or more countries and regions). Satellite mobile broadcasting has the advantages of wide coverage area, stable signal transmission in open areas, and high-speed mobile support for terminals. It is especially suitable for providing information services for vehicle-mounted terminals. [0003] However, during the current process of satellite mobile broadcasting business data transmission, the business can only rely on a single transmission service, such as the transmission service provided solely by the satellite broadcasting network or the Internet transmission service provided ...
