<p><P>PROBLEM TO BE SOLVED: To perform error correction in a synchronous network simultaneously operated with an asynchronous network, by comparing random data for error detection received from the synchronous network with a random data generated by using an identical rule to the above random data for error correction, and by inverting the corresponding bit value of media data synchronized with the random data for error detection when the above random data are different. <P>SOLUTION: A communication apparatus 10 includes a receiving means 10a for receiving from a synchronous network 31 the random data for error detection generated in conformity with the predetermined rule, and for receiving from an asynchronous network 32 the media data synchronized with the random data for error detection; a random data generating means 10b for generating the random data according to the identical rule to the random data for error detection; a comparing means 10c for comparing the generated random data with the random data for error detection received from the synchronous network 31; and an error data inverting means 10d for inverting the corresponding bit value of the media data synchronized with the random data for error detection, when the above random data are different. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
