Digital television receiver and antenna control method therein
First Claim
1. A digital television receiver comprising:
- a receiving section for receiving and processing a channel signal for digital television broadcasting through an antenna having a directivity in dependence upon a control signal for switching patterns of the antenna;
an antenna control section for generating the control signal for switching the patterns of the antenna based on channel information according to the received channel signal; and
an antenna switching control section for switching the patterns of the antenna during a sync signal period of the received channel signal if the control signal is generated.

Abstract
A digital television receiver and antenna control method in the digital television receiver are disclosed. The digital television receiver includes and antenna having directivity according to a control signal for switching patterns of the antenna. A receiving section receives and processes channel signals for digital television broadcasting through the antenna. An antenna control section generates the control signal for switching the patterns of the antenna based on channel information according to the received channel signal. An antenna switching control section switches the patterns of the antenna during a sync signal period of the received channel signal when the control signal is generated.

6. A digital television receiver comprising:
-
an antenna having a directivity in dependence upon a control signal for receiving channel signals for digital television broadcasting, and switching patterns of the antenna;
a signal processing section for tuning the desired channel signal among the broadcasting channel signals, and obtaining a sync signal, channel information for switching the patterns of the antenna, and audio and video signals for display by processing the tuned channel signal;
an antenna control section for generating a control signal for switching the patterns of the antenna according to the channel information; and
an antenna switching control section for switching the patterns of the antenna during a sync signal period of the tuned channel signal in response to an antenna-switching-related signal provided from the antenna control section when the control signal is generated. - View Dependent Claims (7, 8, 9, 10)

11. An antenna control method in a digital television receiver having a signal processing section provided with a direction-adjustable antenna and an equalizer, and an antenna control section for generating a control signal for controlling patterns of an antenna, the method comprising the steps of:
-
(a) receiving a channel signal through the antenna as rotating the antenna;
(b) storing in a storage device the pattern of the antenna and channel information corresponding to the pattern of the antenna when the channel signal is received; and
(c) switching the pattern of the antenna during a sync signal period of the channel signal if an antenna switching request is received from the antenna control section. - View Dependent Claims (12, 13, 14, 15, 16, 17)
