Patent abstract
Disclosed is a television tuner which receives television signals using a smart antenna. It includes an auto-scan unit which makes a channel storing section store receiving channel numbers and receiving directions for a plurality of receiving channels automatically. It also has a channel change unit whereby a receiving direction in which the state of a signal from a tuner section becomes a predetermined one is not stored. When a command to change channels is given, the smart antenna directivity is changed while the signal state is detected, and when the signal state becomes a predetermined one, the smart antenna directivity is retained. This increases the auto-scan processing speed.
