Abstract
A control data transmission and reception period of, for example, 1 ms is provided for each frame of a digital broadcast signal. The digital broadcast signal is intermittently transmitted. In the intermittent transmission, the transmitting device stops the digital broadcast signal from being sent during the control data transmission and reception period. At the same time, control data is transmitted during the control data transmission and reception period. In other words, a beacon signal is sent from a transmitting device to a wireless television receiver as control data, between the intermittent transmissions of the digital broadcast signal. Having received the beacon signal, the wireless television receiver returns a request signal to the transmitting device. As a result, communication between the transmitting device and the wireless television receiver can be established.
