Abstract
When error correction data, which is to be inserted into transmission data at specific intervals, is generated by calculating exclusive-OR of the transmission data, cumulative exclusive-OR of the transmission data is continuously calculated independent of the error correction data insertion intervals. Exclusive-OR between a calculation of the exclusive-OR at the time of the previous error correction data insertion and a calculation of the exclusive-OR at the time of the current error correction data insertion is calculated, thereby generating error correction data to be inserted at the present time. This provides efficient error correction data calculation.
