摘要

The present invention relates to an information distribution system that can reliably distribute an image transmitted from each of two or more transmission apparatuses to a reception apparatus. A transmission apparatus 11 - 1 transmits to a reception apparatus 13 via a network 12 first control information for making a request for transmission of a result of a determination as to whether or not the reception apparatus 13 can receive information. 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 . The present invention can be applied to an information distribution system for distributing image signals.
