<P>PROBLEM TO BE SOLVED: To provide a radio transmittal system for simplifying procedure of viewing fee collection while a restriction in location at viewing and listening a charged content can be reduced. <P>SOLUTION: The radio transmittal system includes a radio transmittal video image transmitting device 3 for converting an entered source signal to an electric wave and transmitting it, and a radio transmittal video image receiving device 4 for converting the electric wave generated from the radio transmittal video image transmitting device 3 to the original source signal as an outer output signal. The radio transmittal system includes a timer circuit 30, a memory 31, and a control circuit 29 in which information of radio connection time between the radio transmittal video image transmitting device 3 and the radio transmittal video image receiving device 4 is formed by using the timer circuit 30 and the formed information is stored in the memory 31 under control. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
