Kanalwählendes Gerät

摘要

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