Problems solved by technology

[0004] However, for a single block, if the loss rate of the data received by the receiving end exceeds its redundancy rate, the block cannot be recovered, and the entire file cannot be recovered directly.
When the network is abnormal, the method of sending file block data in the above natural order will easily lead to the data loss rate of a certain file block exceeding its redundancy rate, resulting in the failure of the file block to be restored, and ultimately the failure of the entire file recovery
Therefore, the existing broadcast data transmission method based on the forward error correction function still needs to be optimized

Embodiment Construction

[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049]The main solution of the embodiment of the present invention is: divide the original broadcast file to be sent into several file blocks; add corresponding forward error correction codes respectively in each divided file block, and the forward error correction codes are used Forward error correction is performed on the broadcast data of the original broadcast file at the broadcast receiving end; each file block added with the forward error correction code is divided into N fragments, wherein N is a positive integer and N≧ 2; Divide the broadcast data of the original broadcast file into N data packets and send them to the broadcast receiving end in turn, wherein each data packet is selected by selecting a fragment from each file block and the selected fragment obtained by encapsulation.

[0050] In the existing f...

Abstract

The invention discloses a broadcasting data transmission method. The method comprises steps: a to-be-transmitted original broadcasting file is divided to a plurality of file blocks; a corresponding forward error correction code is added to each divided file block respectively, wherein the forward error correction code is used for enabling a broadcasting receiving end to carry out forward error correction on the broadcasting data of the original broadcasting file; each file block with the forward error correction code added is divided to N fragments respectively, wherein N is a positive integerand N is no smaller than 2; and the broadcasting data of the original broadcasting file are divided to N data packets, and the N data packets are transmitted to the broadcasting receiving end sequentially, wherein one fragment is selected from each file block and the selected fragment is packaged to form each data packet. The invention also discloses a broadcasting data transmission device, equipment and a computer readable storage medium. Thus, the influence of network anomaly on data loss of a single file block can be reduced, and the reliability of broadcasting data transmission is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a broadcast data sending method, device, equipment and computer-readable storage medium. Background technique [0002] The Flute protocol is a one-way file transfer protocol widely used in mobile multimedia broadcasting systems, and is used to support point-to-multipoint audio and video streams and one-way broadcasting of data files. The Flute protocol has forward error correction (Forward ErrorCorrectmon, referred to as FEC) function, by adding redundant error correction codes in the transmission code column, under certain conditions, the receiving end can automatically correct the transmission error code by decoding, so that To a certain extent, the reliability of data one-way transmission is guaranteed. Due to the one-way transmission of broadcast data, the forward error correction capability of Flute protocol data is very important, which directly affects t...
