Channel selection apparatus

摘要

A channel selection apparatus for sorting broadcast signals detects parity errors of plural broadcast signals transmitted from the same broadcasting station. The tuned frequency of the broadcast signal is shifted from the frequency of a normal broadcast signal by a predetermined value. As a result, field intensity of the broadcast signal correlates more closely with a parity error rate. The channel selection apparatus thus can sort broadcast signals in the order of fewer error rates and assign them to tuning buttons in the order of easier selecting operation.
