Television tuner for controlling directivity of an antenna

摘要

Disclosed is a television tuner for receiving television broadcast signals with a smart antenna, which is equipped with an auto-scan unit that causes a channel storing section to automatically stores a receiving channel and the corresponding receiving direction at the time when the signal condition from a tuner section matches the predetermined signal condition matches the predetermined signal condition. The auto-scan unit causes a directivity control section to perform a variable directivity control for every direction and to detect the signal condition for each direction, and switches the receiving channel in the tuner section when a receiving direction is stored. This improves the convenience in adjusting the antenna directivity for each receiving channel.
