<p><P>PROBLEM TO BE SOLVED: To enable communication quality to be retained, security against intersection to be secured, and a communication path to be switched without any interruption of communication, and to provide a technique for restraining processing time and the number of adjustment parameters. <P>SOLUTION: When communication information is divided into a plurality of communication blocks for coding, the coding is made by such a coding system requiring information blocks at least by a prescribed threshold for decoding the original communication information from the plurality of information blocks. When there are at least two communication paths that can be used when transmitting the information blocks to a communication device of one's other party, the number of information blocks to be transmitted per communication path is assigned to each communication path by a number less than the threshold required for decoding the information blocks, and the assigned number of information blocks are transmitted to each communication path. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
