Abstract
A TV receiver has a tuner and a controller for controlling a tuning operation of the tuner. The controller includes a calculation unit for effecting a calculation of preferred stations using as parameters tuned channels and the times for which the channels are selected. A tuning frequency arrangement storing unit determines the channels that are frequently watched by a user on the basis of the calculation and stores indications of the channels. The channel indications thus stored are read out in ranked order to perform a tuning operation in response to successive actuation of a preferred-station key.
