Periodical refreshing for radio channels quality indicator

摘要

This method for receiving a data stream transmitted over several radiofrequency (RF) channels, each with a different frequency, comprises:
- scanning (2) the bandwidth to identify available radiofrequency channels;
- determining (4) a quality indicator for each available radiofrequency channel;
- selecting (6) a channel for receiving the data stream depending upon said quality indicators; and
- refreshing (10) periodically the quality indicators of the selected channel. The method further comprises determining (20) the refreshing period of at least said selected channel based upon the corresponding quality indicator.
