The invention provides a broadcast receiver having a single tuner that can be tuned away from a first frequency, from which a first broadcast signal is being received, to a second frequency to detect alternative broadcast signals and tuned back to the first frequency to continue receiving the first broadcast signal without an interruption to the received service. This utilises the fact that, in systems such as OFDM systems, not all broadcast data packets within a received frame are required to be decoded in order to receive a desired broadcast service. As such, the tuner can be tuned away, detect alternative services and tuned back to the original frequency to continue receiving the first broadcast service without any perceivable break (to the user) in the reception of the first broadcast service. |
