Abstract
According to one embodiment, a signal quality monitoring apparatus includes a signal processor, a comparator and a determiner. The processor obtains output signals from a first transmitter and a second transmitter which are mutually redundant and respectively reproduce digital broadcast signals based on a common origin signal, and generates a first signal based on the output signal from the first transmitter and a second signal based on the output signal from the second transmitter. The comparator compares the first signal and the second signal. The determiner determines a quality of the digital broadcast signal based on a result of the comparison.
