Abstract

본 발명은 채널 자동 선국시 채널 중복 방지 방법에 관한 것으로서, 이를 위하여, 자동 채널 선국시 수신되는 영상 신호의 세기를 일정하게 유지하기 위한 자동 이득 조정 신호를 이용하여 동일한 방송신호가 중복되어 선국되는 것을 방지하는 방법으로, 자동 채널 선국이 종료되면 선국된 각 채널을 상호 비교하여 국부 발진 주파수가 동일한 채널이 있는지 체크하는 과정과; 상기 체크 과정에서 국부 발진 주파수가 동일한 채널이 있으면 두채널의 상기 자동 이득 조정 신호의 세기를 비교하는 과정과; 상기 비교 과정에서 자동 이득 조정 신호의 세기가 큰 채널과 작은 채널을 구분하여 디스플레이하고, 자동 이득 조정 신호의 세기가 같을 경우 채널과 채널 대역을 디스플레이하는 과정과; 상기 선국된 채널중 사용자가 선택한 채널을 지우고 채널 비교가 종로될 때까지 상기 채널 비교 과정과; 상기 선국된 채널중 사용자가 선택한 선택한 채널을 지우고 채널 비교가 종료될 때까지 상기 채널 비교 과정을 반복하는 과정을 포함하는 채널 자동 선국시 채널 중복 방지 방법을 제공하므로서, 채널 중복을 방지한 것이다.(선택도 : 제2도)The present invention relates to a method of preventing channel duplication during automatic channel tuning. To this end, the same broadcast signal is repeatedly tuned using an automatic gain adjustment signal for maintaining a constant intensity of a video signal received during automatic channel tuning. As a method of preventing, when automatic channel tuning is terminated, comparing each channel tuned to each other and checking whether there are channels having the same local oscillation frequency; Comparing the strengths of the automatic gain adjustment signals of the two channels if there is a channel having the same local oscillation frequency in the checking process; Displaying a channel with a large intensity of the automatic gain adjustment signal and a small channel in the comparison process, and displaying a channel and a channel band when the strength of the automatic gain adjustment signal is the same; The channel comparison process until the channel selected by the user among the tuned channels is deleted and channel comparison is terminated; It is possible to prevent channel duplication by providing a channel duplication prevention method for channel auto-tuning including the step of deleting the selected channel selected by the user among the tuned channels and repeating the channel comparison process until the channel comparison is completed.

Claims (1)

자동 채널 선국시 수신되는 영상 신호의 세기를 일정하게 유지하기 위한 자동 이득 조정 신호를 이용하여 동일한 방송 신호가 중복되어 선국되는 것을 방지하는 방법으로서, 자동 채널 선국이 종료되면 선국된 각 채널을 상호 비교하여 국부 발진 주파수가 동일한 채널이 있는지 체크하는 과정과; 상기 체크 과정에서 국부 발진 주파수가 동일한 채널이 있으면 두채널의 상기 자동 이득 조정 신호의 세기를 비교하는 과정과; 상기 비교 과정에서 자동 이득 조정 신호의 세기가 큰 채널과 작은 채널을 구분하여 디스플레이하고, 자동 이득 조정 신호의 세기가 같을 경우 채널과 채널 대역을 디스플레이하는 과정과; 상기 선국된 채널중 사용자가 선택한 채널을 지우고 채널 비교가 종료될 때까지 상기 채널 비교 과정을 반복하는 과정을 포함하는 채널 자동 선국시 채널 중복 방지 방법.A method for preventing duplication of the same broadcast signal by using an automatic gain adjustment signal for maintaining a constant intensity of a video signal received during automatic channel tuning.At the end of automatic channel tuning, the channels tuned to each other are compared with each other. Checking whether there are channels having the same local oscillation frequency; Comparing the strengths of the automatic gain adjustment signals of the two channels if there is a channel having the same local oscillation frequency in the checking process; Displaying a channel with a large intensity of the automatic gain adjustment signal and a small channel in the comparison process, and displaying a channel and a channel band when the strength of the automatic gain adjustment signal is the same; And erasing the channel selected by the user from the tuned channels and repeating the channel comparison process until the channel comparison is completed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
