When the reception apparatus 13 receives the first control information, the reception apparatus 13 generates second control information indicating whether or not to receive the information transmitted by the transmission apparatus 11 - 1 , and transmits the second control information to the transmission apparatus 11 - 1 via the network 12 . When the received second control information is information indicating that the information is not received, the transmission apparatus 11 - 1 prohibits the transmission of the information to the reception apparatus 13 .
