Abstract: 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.

Abstract: A remote operating system including a remote operating device 20 having the transmitting/receiving function and a learning function, a slave unit 30 provided in any of a variety of main body members of the electronic equipment remote-operated by the remote operating device, and a master unit 10 for the slave unit. An identification code generating circuit 11 of the master unit 10 generates an identification code as the identification information. The master unit 10 transmits the identification code from a transmitter 13 to the remote controlling unit 20 by an IR beam, while transmitting the identification code from a sender/receiver 14 over a cable to the slave unit 30. The remote operating unit 20 appends the identification code associated with an operating switch 21 to form a remote operating signal which is transmitted to the slave unit 30.
