Abstract (en)
A programme switching method of switching a radio tuner between frequencies on which related radio stations broadcast, the method comprising: tuning the radio tuner to a first frequency on which a first radio station broadcasts so as to receive a first programme signal of the first radio station; detecting, in the first programme signal, an information code indicating a second frequency on which a second, related radio station broadcasts; periodically monitoring at least one quality indicator of a second programme signal of the second frequency; detecting, in the first programme signal, a transmission code indicating transmission of a particular type of programme in the second programme signal on the second frequency; determining, from the monitored at least one quality indicator of the second programme signal, whether the second programme signal is receivable; and switching the radio tuner to the second frequency to receive the said second programme signal if it is determined that the second programme signal is receivable, and keeping the radio tuner tuned to the first frequency to continue receiving the first programme signal if it is determined that the second programme signal is not receivable.
