First Claim
Patent Images
1. A receiver system of broadcasting in an operation area comprising:
- a first receiver for receiving a first signal sent out from a satellite;
a second receiver for receiving the second signal sent out from a ground facility;
a signal selection data acquisition unit for acquiring signal selection data that controls selection of one of the first and second signals for broadcasting reception in a current operation area; and
a control unit for controlling execution of a predetermined process that utilizes ones of the first and second signals based on the signal selection data that is acquired by the signal selection data acquisition unit,wherein when a selected one of the first and second signals is utilized, the control unit is configured to continue to utilize the selected signal throughout the current operation area until the selected signal cannot be acquired, regardless of whether later signal selection data indicates a non-selected signal to be preferable to the selected signal.

Abstract
A receiver system equipped with a first and second reception units for receiving a satellite radio broadcasting prevents a reception unit switching operations by using signal selection data that provides satellite availability for respective operation areas. The satellite radio broadcasting reception quality in each of the respective operation areas is improved because of the reduced chance of dropout or the like in the broadcasted contents of the satellite radio broadcasting received by the receiver system.
