<p><P>PROBLEM TO BE SOLVED: To provide a broadcast communication system for performing transmission in accordance with the reception state of a receiver when transmitting one piece of information from a transmitter to a plurality of receivers by broadcast communication. <P>SOLUTION: Each broadcast communication client 23 sets a value of a bit corresponding to post-division data received by itself to "1", and a value of a bit corresponding to post-division data not received by itself to "0" concerning the post-division data transmitted from a broadcast communication server 21. When the broadcast communication server 21 receives the reception state information of such bit strings as "11101101", "11001101", and "11000101" from the broadcast communication clients 23-1 to 3, the broadcast communication server 21 obtains a logical product of each bit in each bit string so as to acquire a bit string of "11000101". Then, it is determined that post-division data with sequence numbers "2", "3", "4", "6" are not received by any of the broadcast communication clients 23. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
