<p>A communication device (1) transmits to a relaying device (2) a transmission right grant request for requesting a grant of a transmission right to a transmitting device (3), and the relaying device (2) determines whether the received transmission right grant request is a command associated with the transmission right of the communication device (1) or a command associated with the transmitting device (3), and if it determines that it is the command associated with the transmitting device (3), it grants the transmission right to the transmitting device (3), and starts broadcasting of data being transmitted from the transmitting device (3). In addition, when receiving from the communication device (1) an operation command for operating the transmitting device (3), the relaying device (2) determines a type of the command and transmits it to the transmitting device (3). The device may allow, for example, respective users of PoC-capable mobile telephones to share usage of a digital camera.</p> |
