Patent ID: 7369826

Claim:
A method for monitoring DRM broadcast signals at alternative frequencies during reception of a DRM broadcast signal at a present frequency, said DRM broadcast signals including static data symbols during time slots and radio program data during time intervals, said time slots and said time intervals being arranged in a sequence, in which one time slot is followed by one time interval and vice versa, said method comprising: receiving radio program data at a present frequency during a first time interval with a receiver gain of a present gain value; switching to an alternative frequency during a first time slot, wherein during said first time slot said receiver's gain settles to a second gain value; switching to said present frequency during a second time interval; receiving further radio program data at said present frequency during said second time interval with a receiver gain of said present gain value; switching to said alternative frequency during a second time slot to check a broadcast signal; instantaneously switching the receiver's gain from said present gain value to said second gain value; and checking said broadcast signal at said alternative frequency during said second time slot.
