Abstract:
A digital broadcast receiver for receiving digital broadcast signals in which control data are multiplexed with a plurality of sets of program data, comprising:means for receiving the digital broadcast signals and outputting a status signal indicating whether the signals are receivable or unreceivable and a bit error rate signal obtained by arithmetic operation, and control means for controlling the receiver so that, when the bit error rate signal has risen in level to a first value, the status signal that is outputted changes from indicating a state of possibility of reception to indicating a state of impossibility of reception; when the bit error rate signal has dropped in level to the first value, the status signal that is outputted changes from indicating a state of impossibility of reception to indicating a state of possibility of reception; and when the bit error rate signal has further dropped in level to a second value less than the first value, the control data are acquired.
