Abstract

PURPOSE: A method and circuit for searching a television broadcasting channel are provided to display the channel currently broadcasting on a liquid crystal monitor to allow a user to easily confirm the current broadcasting channel. CONSTITUTION: A user searches broadcasting channels in order to watch a broadcasting program he/she wants. When the user pushes a search key, data stored in a microcomputer is read. The read data is output. It is checked whether or not a stop key is inputted. When the stop key is inputted, the broadcasting channel at that time is output. When the stop key is not inputted, a timer is counted up to check whether or not timer is over. When the timer is over, a memory counter is counted up. It is checked whether or not the memory counter is over. When the memory counter is over, the memory counter is set to an initial value.

Description

텔레비젼방송채널 탐색 제어방법 및 회로TV broadcasting channel search control method and circuit

본 발명은 탐색키를 누르면 마이컴에 순차적으로 메모리되어 있는 방송채널이 수초간 모니터에 디스플레이하여 사용자가 원하는 방송에서 채널(CH)이 멈추게 함으로써 시청자가 방송채널을 일일이 돌려서 확인해야 하는 번거로움과 불편함을 해소시킬 수 있도록 하는 텔레비전방송채널 탐색제어방법 및 회로에 관한 것이다.According to the present invention, when a search key is pressed, a broadcasting channel sequentially stored in the microcomputer is displayed on a monitor for several seconds so that the channel (CH) stops at a desired broadcasting, and the viewer has to check the broadcasting channel by turning the broadcasting channel one by one. The present invention relates to a television broadcast channel search control method and circuit for solving the problem.

현재 일반가정용 텔레비전이나, 차량용 텔레비전에서는 각 지역에 따라 방송채널이 다르기 때문에 시청자가 현재의 방송을 시청하다가 타 방송채널에서 무엇이 방송되는지 확인하려면 방송채널을 일일이 돌려야 하는 문제점이 있었다.In general home televisions and car televisions, since broadcasting channels are different according to regions, viewers have to turn the broadcasting channels one by one to check what is being broadcasted in other broadcasting channels while watching the current broadcasting.

그런데 텔레비전 시청자가 타 방송국의 방송상태를 확인하려면 일일이 방송채널을 확인해야 하는 불편함과, 또한 사용자가 각 방송채널을 기억해야 하고, 또한 그 방송채널을 직접 눌려가면서 확인해야만 하였던 것이다. 특히 차량용 텔레비전은 자동차가 타 지역으로 이동하기 때문에 그 지역의 방송채널을 몰라 시청자가 방송채널을 찾기가 매우 어려웠던 것이다.However, in order for the television viewer to check the broadcasting state of another broadcasting station, the inconvenience of having to check the broadcasting channel one by one, and the user had to remember each broadcasting channel, and also had to confirm while pressing the broadcasting channel directly. In particular, in the case of car television, because the car moves to another region, it was very difficult for viewers to find the broadcasting channel because they did not know the broadcasting channel of the region.

본발명은 상기와 같은 종래의 문제점을 해결하고자 이루어진 것으로서, 그 목적은 마이컴에 현 방송채널을 자동메모리 시킨 후 탐색키가 눌려졌을 때 마이컴에서는 순차적으로 메모리된 채널 데이터를 모니터에 수초간 디스플레이하여 시청자가 원하는 방송에서 채널을 멈추게 함으로써 현재 어떤 채널에서 어떤 방송을 하고 있는지를 확인시켜 주므로써 방송채널을 일일이 돌려서 확인해야 하는 번거로움과 불편함을 해소시킬 수 있도록 하는 데 있다.The present invention has been made to solve the conventional problems as described above, and its purpose is to automatically display the current broadcast channel in the microcomputer, and then when the search key is pressed, the microcomputer sequentially displays the memorized channel data on the monitor for several seconds. By stopping the channel in the desired broadcast to confirm which channel is currently broadcasting in which channel by eliminating the hassle and inconvenience of having to check by turning the broadcast channel one by one.

이를 첨부도면에 의거하여 본발명을 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings as follows.

제 1 도는 텔레비전방송채널을 탐색하기 위한 본발명의 블록구성도로서, 제 1 도에 도시한 바와같이, 안테나(ANT)로부터 수신된 방송신호를 검파하는 텔레비전튜너부(10)와, 검파된 방송신호를 영상화 또는 음성화하는 영상부(20) 및 음성부(30)와, 영상신호를 디스플레이시키는 액정모니터(40)와, 음성신호를 증폭시켜 스피커(SP)로 출력하는 증폭기(50)를 구성한 것에 있어서,FIG. 1 is a block diagram of the present invention for searching for a television broadcast channel. As shown in FIG. 1, a television tuner unit 10 for detecting a broadcast signal received from an antenna ANT, and detected broadcast. A video unit 20 and an audio unit 30 for imaging or sounding a signal, a liquid crystal monitor 40 for displaying a video signal, and an amplifier 50 for amplifying an audio signal and outputting the audio signal to the speaker SP. In

상기 텔레비전튜너부(10)에 사용자가 방송채널을 탐색하여 원하는 방송을 시청할 수 있게 하는 탐색키(60)와, 시청자가 원하는 방송이면 채널을 정지시키는 정지키(70)와, 현 방송채널을 모두 메모리시키는 마이컴(80)과, 그 방송채널에 맞는튜닝전압을 출력하는 튜닝시스템부(90)로 이루어진 방송채널제어회로부(100)를 연결하여서 구성한 것이다.In the television tuner unit 10, a search key 60 for allowing a user to search for a broadcast channel to watch a desired broadcast, a stop key 70 for stopping the channel if the viewer wants the broadcast channel, and a current broadcast channel The broadcasting channel control circuit unit 100 is configured by connecting a microcomputer 80 to be stored in memory and a tuning system unit 90 for outputting a tuning voltage for the broadcasting channel.

제 2 도는 본발명에 따른 플로우차트로서, 제 1 도과 제 2 도에 따라 본 발명의 작용효과를 설명하면 다음과 같다.2 is a flowchart according to the present invention, the operation and effect of the present invention according to the first and second views as follows.

우선 안테나(ANT)로부터 방송신호가 수신되면 텔레비전 튜너부(10)에서는 방송신호를 검파하여 검파한 신로를 영상신호부(20)로 보낸다.First, when a broadcast signal is received from the antenna ANT, the television tuner unit 10 detects the broadcast signal and sends the detected signal to the video signal unit 20.

그럼 영상신호부(20)에서는 검파된 방송신호를 영상화하여 액정모니터(40)에 디스플레이시키고, 따라서 음성부(30)에서는 영상신호를 음성화하여 음성화한 신호를 증폭기(50)로 증폭시킨 다음 스피커(SP)로 증폭된 음성신호를 출력한다.Then, the video signal unit 20 visualizes the detected broadcast signal and displays it on the liquid crystal monitor 40. Therefore, the audio unit 30 amplifies the voiced signal by amplifying the video signal by the amplifier 50 and then the speaker ( A voice signal amplified by SP) is output.

이와 동시에 방송되는 채널은 마이컴(110)내의 프로그램에 의해 메모리되어 사용자가 원하는 방송을 시청하게 된다.At the same time, the broadcast channel is memorized by the program in the microcomputer 110 to watch the broadcast desired by the user.

그러나 본발명은 마이컴(80)에 현재 방송채널이 모두 메모리되어 있는 상태에서 사용자가 원하는 방송을 시청하기 위해 탐색키(60)를 누르면 마이컴(80)에서는 그 방송채널에 맞는 튜닝전압데이터가 도면에 도시 생략된 피-엘-엘(PLL)회로부에 의해 펄스폭변조(PWM)신호를 튜닝시스템부(90)에 전송한다.However, according to the present invention, when the current broadcast channel is all stored in the microcomputer 80, the user presses the search key 60 to watch the desired broadcast. In the microcomputer 80, the tuning voltage data corresponding to the broadcast channel is shown in the figure. A pulse width modulated (PWM) signal is transmitted to the tuning system unit 90 by a P-L-L circuit unit (not shown).

그러면 튜닝시스템부(90)에서는 그 방송채널에 맞는 튜닝전압데이터를 텔레비전튜너부(10)에 보내면 영상부(20)에서는 튜닝전압을 영상화하여 액정모니터(40)에 순차적으로 수초간 디스플레이시켜 사용자가 원하고자 하는 방송채널을 확인할 수 있게 된다.Then, the tuning system unit 90 transmits the tuning voltage data corresponding to the broadcast channel to the television tuner unit 10, and the image unit 20 images the tuning voltage and sequentially displays it on the liquid crystal monitor 40 for several seconds. The desired broadcast channel can be identified.

또한 액정모니터(40)에 순차적으로 수초간 방송채널이 디스플레이 될때 사용자가 원하는 방송채널에서 정지키(70)를 누르면 사용자가 원하는 방송을 시청할 수 있고, 또한 순차적으로 수초간 방송채널이 모니터에 디스플레이될 때 방송채널의 프로그램도 확인할 수 있게 되는 것이다.In addition, when the broadcasting channel is sequentially displayed on the LCD monitor 40 for several seconds, pressing the stop key 70 on the desired broadcasting channel enables the user to watch the desired broadcasting, and the broadcasting channel is sequentially displayed on the monitor for several seconds. When the program of the broadcast channel can also be confirmed.

정지키입력이 아니면 마이컴(80)내의 타이머를 업시켜 타이머오버인가를 체크한다. 타이머오버이면 다시 메모리카운터를 업시키고, 메모리카운터 오버인가를 체크하여 오버이면 메모리카운터를 초기치로 설정한다.If the stop key is not input, the timer in the microcomputer 80 is turned up to check whether the timer is over. If the timer is over, the memory counter is increased again. Check if the memory counter is over. If the timer is over, set the memory counter to the initial value.

이상에서와 같이 본발명은 현 방송채널을 마이컴에 메모리 시킨 후 사용자가 탐색키를 누르면 마이컴에 메모리된 방송채널데이터가 순차적으로 수초간 출력되어 현재 방송되고 있는 채널을 액정모니터에 디스플레이시킴으로써 방송채널을 확인하려는 번거로움과 불편함을 해소시켜 주는 효과가 있다.As described above, according to the present invention, when a user presses a navigation key after storing a current broadcasting channel in a microcomputer, the broadcasting channel data stored in the microcomputer is sequentially output for several seconds, thereby displaying a broadcasting channel by displaying the currently broadcasting channel on a liquid crystal monitor. There is an effect that eliminates the hassle and inconvenience to check.
