ABSTRACT:
A broadcast receiver which detects the reception status of radio waves from other stations without deteriorating the reception status of a currently-receiving station, in digital broadcasting where consecutive time series data is transmitted. The amount of time-based interleave applied to the currently-receiving data is determined so that the reception status of the radio waves from other stations is detected while the reception of the currently-receiving broadcast station is interrupted within the extent where missing data can be recovered by such interleave and error correction processing on demodulation.
