Patent ID: 7734946

Claim:
A transmission/reception system, comprising: a transmission apparatus for transmitting transmission data; and a reception apparatus for receiving the transmission data transmitted from the transmission apparatus; the transmission apparatus being operable to: produce first data by dividing the transmission data into blocks having a predetermined size, select a plurality of the blocks of first data, produce second data based on results of an exclusive OR operation on the selected plurality of blocks of first data, add to the first data first relating information for enabling the reception apparatus to restore the first data, add second relating information to the second data, packetize the first data and the second data, and transmit the resulting packets to the reception apparatus; and the reception apparatus being operable to: receive both of the first data and the second data, decide, based on the first relating information, whether the reception apparatus fails to receive some of the first data, produce, when it is decided that the reception apparatus fails to receive some of the first data, an exclusive OR operation-based determinant for restoring the first data by using the second relating information, and solve the produced determinant to restore the first data.
