    • PROBLEM TO BE SOLVED: To provide a reception method and a receiver more suitable for a mobile environment. SOLUTION: The method of receiving a data stream to be transmitted via some radio frequency (RF) channels each having different frequency includes the process 2 of identifying a radio frequency channel capable of being used by scanning a band width, the process 4 of determining a quality indicator relating to each usable radio frequency channel, and the process 6 of selecting a channel for receiving the data stream in response to the quality indicator. The above method further includes the process 20 of determining a refreshing period relating to the quality indicator of each usable channel, and of weighting each predetermined refreshing period in response to a value of the quality indicator of the channel which is now received.
