Patent ID: 7711076

Claim:
A method for controlling a digital broadcast receiving terminal, comprising: initially activating a first receiving unit and a second receiving unit; receiving a digital broadcast signal at the first and second receiving units; determining a reception environment based upon said digital broadcast signal; and selectively operating said first and said second receiving units based upon said reception environment; wherein said determining said reception environment comprises: determining a signal-to-noise ratio (SNR) for an antenna associated with at least one of said first or said second receiving units; detecting bit error rate (BER), prior to decoding, of said digital broadcast signal, wherein if said BER does not exceed a first threshold value, then said determining said reception environment further comprises: determining an activated receiving unit, said activated receiving unit being defined as one of said first or said second receiving units that is assigned to a reference finger; and determining a signal-to-noise ratio (SNR) for an antenna associated with said activated receiving unit, wherein if said SNR exceeds a second threshold value, then said method further comprises: applying power to said activated receiving unit; and discontinuing power to a discontinued receiving unit, said discontinued receiving unit being defined as one of said first or said second receiving units that is not assigned to said reference finger.
