[0030] see figure 1 , the method process of the present invention is as follows:
[0031] 100) Split the data to be sent into multiple data blocks, and calculate the checksum of each data block;
[0032] 200) performing an XOR operation on the multiple data blocks to calculate the protection data block;
[0033] 300) Sending data block content, including protecting data block content;
[0034] 400) Receive the data block, check whether the received data block is correct, and mark it.
[0035] 500) If there is a data error, count the number of error data blocks, and if only one data block has an error and the protection data block is received, perform error correction and restoration of the data block.
[0036] 600) If there is no data error, according to the coding rules, directly splice and restore the data.
[0037] see figure 2 , the inventive method detailed process description is as follows:
[0038] 100) split the data to be played into n data blocks by Y bytes, w...
