A receivable service is selected from each ensemble of a digital broadcast, and the error rate of the selected service is measured. Only a service belonging to an ensemble containing a service which satisfies a predetermined reference value is searched and preset. A service belonging to an ensemble containing a service with a low error rate is searched and preset, with priority over a service belonging to an ensemble containing a service with a high error rate. The reception level of a receivable service may be used instead of the error rate as the selection reference for processing.
