PROBLEM TO BE SOLVED: To provide a receiver that can prevent setting of an erroneous parameter even when a received TMCC(transmission and multiplexing configuration control) signal has an error due to a deteriorated reception environment. SOLUTION: A count down signal from a count down generating circuit 16 is inserted to a TMCC signal outputted from a TMCC mask circuit 18, and the count down signal is forcibly set to a usual value '15' because an error flag is set to '1' in the case that the received TMCC signal has an error due to fading or the like. When the error flag is set to '0', a count down signal that is cyclicly decremented by one each for each input of a frame pulse from '15' until '0', can be obtained. Thus, even when an error is caused in the received TMCC signal due to fading or the like, mis-setting of a parameter to the receiver can be prevented and the setting can be restored to a regular value. |
