Abstract

텔레비젼 수상기의 방송신호 자동검출방법을 개시한다.A method for automatically detecting a broadcast signal of a television receiver is disclosed.

존재하는 방송사 채널의 개수를 k로 설정하고, 임의의 변수 n을 1로 초기치 설정하는 단계(100단계); 각 방송사의 방송신호를 수신하는 복수의 채널을 저장하는 단계(102단계); 현재 동조된 채널을 통하여 무선신호를 수신하는 단계(104단계); 상기 104단계에서 수신된 무선신호를 디스플레이하는 단계(106단계); 상기 106단계에서 수신되고 있는 채널에 방송신호의 존재여부를 판단하는 단계(108단계); 상기 108단계에서 판단된 결과가 수신되는 방송신호가 소정의 시간 간격동안 존재하지 않으면 상기 102단계에서 저장된 채널중 현재 채널의 다음 채널을 검색하는 단계 (110단계); 임의의 변수 n과 상기 100단계에서 정의된 변수 k의 관계가 'n k' 인가를 판단하는 단계(112단계); 상기 112단계의 판단이 'n k'이면 임의의 변수 n에 '1'을 가산하고 상기 106단계를 수행하는 단계(114단계); 및 상기 112단계의 판단이 'n k' 가 아니면 전원을 오프시키는 단계(116단계)를 포함한다. 따라서, 사용자의 번거로운 제어 동작이 필요하지 않고 자동적으로 채널 전환되므로 제어의 편의성을 향상시키는 효과를 제공한다.Setting the number of existing broadcasting channels to k and setting an arbitrary variable n to 1 as an initial value (step 100); Storing a plurality of channels for receiving broadcasting signals of each broadcasting company (step 102); Receiving a radio signal through the currently tuned channel (step 104); Displaying the radio signal received in step 104 (step 106); Determining whether a broadcast signal is present in the channel received in operation 106; If the broadcast signal received in step 108 does not exist for a predetermined time interval, searching for the next channel of the current channel among the stored channels in step 110; Determining whether a relation between an arbitrary variable n and a variable k defined in the step 100 is 'n k' (operation 112); If the determination in step 112 is 'n k', adding '1' to an arbitrary variable n and performing step 106 (step 114); And turning off the power if the determination in step 112 is not 'n k' (step 116). Therefore, the user does not need troublesome control operation and is automatically switched to the channel, so that the convenience of control is improved.

Description

Automatic detection method of broadcasting signal of TV receiver

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 본 발명에 따른 텔레비젼 수상기의 방송신호 자동검출방법을 설명하는 흐름도이다.FIG. 1 is a flowchart illustrating a method of automatically detecting a broadcast signal of a television receiver according to the present invention.

Claims

A method for automatically detecting a broadcast signal of a television receiver, the method comprising: setting a number of existing broadcasting channels to k and setting an arbitrary variable n to 1 as an initial value (step 100); A step (102) of setting a plurality of channels for receiving broadcast signals of respective broadcasting companies; Receiving a radio signal through the currently tuned channel (step 104); Displaying the radio signal received in step 104 (step 106); Determining whether a broadcast signal is present in the channel received in operation 106; If the received broadcast signal is present in step 108, step 106 is performed. If the received broadcast signal does not exist for a predetermined time interval, the next channel of the current channel, which is stored in step 102, Searching (step 110); Determining whether a relation between an arbitrary variable n and a variable k defined in the step 100 is 'n k' (operation 112); If the determination in step 112 is 'n k', adding '1' to an arbitrary variable n and performing step 106 (step 114); And turning off the power of the television receiver if the determination in step 112 is not 'n k' (step 116).
