<P>PROBLEM TO BE SOLVED: To transmit content just after starting even when restarting is performed. <P>SOLUTION: This data broadcast transmitter 5 is provided with: a self-running mode processing part 14 for transmitting content on the basis of an internal device clock corrected to a broadcasting station time and broadcast progress data supplied from a data broadcast controller 4, and an external control mode processing part 15 for transmitting content according to a transmission control signal input from an automatic program controller (APC). A mode switching part 16 determines types (self-running mode/external control mode) of operation modes adopted at starting under the control of a CPU 11. When the determination determines that the external control mode is adopted, the CPU 11 once makes switching to the self-running mode to transmit content on the basis of the broadcast progress data by the self-running mode processing part 14, and makes switching to the external control mode when content transmission starting is confirmed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
