본 발명은 방송선국장치에 관한 것으로서, 특히, 일반적인 무선조정장치나 방송선택버튼을 사용하여 다수개의 수신방송을 간단히 조사할 수 있도록한 방송선국장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast tuning device, and more particularly, to a broadcast tuning device that enables a simple survey of a plurality of received broadcasts using a general radio control device or a broadcast selection button.

일반적인 방송수신장비의 하나인 텔레비젼은 수신회로와 동기편향회로와 전원장치와 출력장치인 스피커 및 수상관으로 이루어진다. 상기 수신회로는 튜너회로를 포함하여 구성되며 공중파인 다수개의 전파를 수신하여 원하는 방송만을 선택하여 출력한다.A television, which is one of the general broadcasting receivers, is composed of a receiver circuit, a synchronous deflection circuit, a power supply unit, an output device, a speaker, and a water pipe. The receiving circuit includes a tuner circuit and receives and outputs a desired broadcast by receiving a plurality of radio waves which are aerial waves.

도 1은 종래의 방송선국장치의 블록도이다.1 is a block diagram of a conventional broadcasting station.

종래의 방송선국장치는 시청자가 원하는 방송을 선택 입력하는방송선택버튼(10)과 상기 방송선택버튼(10)의 출력신호를 입력받아 다수개의 수신 주파수에서 하나의 주파수만을 선택증폭하여 출력하는 튜너회로(20)를 포함한다.Conventional broadcasting tuning apparatus is a tuner circuit for receiving a broadcast selection button 10 for selecting and inputting a broadcast desired by the viewer and the output signal of the broadcast selection button 10 to selectively amplify and output only one frequency from a plurality of reception frequencies. And 20.

시청자가 원하는 방송을 선택하여 방송선택버튼(10)의 숫자버튼이나 채널 업/다운 버튼을 누르면 튜너회로(20)에서는 입력된 다수개의 수신 주파수에서 하나의 주파수만을 동조하여 선택한후 증폭하고 상기 증폭된 신호를 중간주파 신호로 변환하여 출력한다.When a viewer selects a desired broadcast and presses a number button or a channel up / down button of the broadcast selection button 10, the tuner circuit 20 tunes and selects only one frequency from a plurality of input frequencies, and then amplifies the amplified signal. The signal is converted into an intermediate frequency signal and output.

그러나 종래의 방송선국장치에서는 방송선택버튼의 숫자버튼이나 채널 업/다운 버튼을 누르면 한 번에 한 방송만을 선택된다. 그러므로 방송의 선택의 폭이 점점 넓어지는 케이블 텔레비젼이나 위성방송 등 방송을 채널이 많은 경우 모두 조사하여 원하는 방송을 선택하기 위해서는 방송선택버튼를 여러번 눌러야 하는 문제점을 가진다.However, in the conventional broadcast channeling apparatus, when a number button or a channel up / down button of a broadcast selection button is pressed, only one broadcast is selected at a time. Therefore, there is a problem of pressing the broadcast selection button several times in order to select a desired broadcast by investigating all broadcasts such as cable TV and satellite broadcast, which have a wider selection of broadcasts.

따라서, 본 발명의 목적은 기능버튼의 추가 없이 채널 업/다운 버튼을 사용하여 많은 채널의 방송을 조사하여 선택할 수 있는 방송선국장치를 제공하는데 있다.Accordingly, it is an object of the present invention to provide a broadcasting station apparatus capable of irradiating and selecting broadcasts of many channels using channel up / down buttons without adding a function button.

상기 목적을 달성하기 위한 본 발명에 따른 방송선국장치는 시청자가 원하는 방송을 선택 입력면 방송선택신호를 출력하는 방송선택버튼과 상기 방송선택신호를 입력받아 다수개의 수신 주파수에서 하나의 주파수만을 선택증폭하여 출력하는 튜너회로를 가지는 방송선국장치에 있어서, 상기 방송선택신호의 입력시간을 판단하여 다수개의 방송을 순차적으로 선택하는 조사선국신호 또는 일반방송선택신호를 출력하는 조사선국장치를 포함한다,In accordance with an aspect of the present invention, a broadcast channel selection device selects a broadcast desired by a viewer, and selects and broadcasts a broadcast selection button for outputting a broadcast selection signal and the broadcast selection signal. A broadcasting channel tuning device having a tuner circuit for outputting a radio frequency signal, comprising: an irradiation channel tuning signal for sequentially selecting a plurality of broadcasts by judging an input time of the broadcasting selection signal or a general broadcasting selection signal;

상기 조사선국장치는 조사선국판단부와, 조사선국신호발생부를 포함한다.The irradiation tuning device includes an irradiation tuning decision unit and an irradiation tuning signal generator.

본 발명에 따른 방송선국장치는 시청자가 원하는 방송을 선택 입력하면 방송선택신호를 출력하는 방송선택버튼(10)과, 상기 방송선택신호의 입력시간을 판단하여 다수개의 방송을 순차적으로 선택하는 조사선국신호 또는 일반방송선택신호를 출력하는 조사선국장치(30)와, 상기 조사선국신호 또는 일반방송선택신호를 입력받아 다수개의 수신 주파수에서 하나의 주파수만을 선택증폭하여 출력하는 튜너회로(20)로 구성된다.The broadcasting channel selection apparatus according to the present invention has a broadcast selection button 10 which outputs a broadcast selection signal when the viewer selects and inputs a desired broadcast, and a irradiation selection station that sequentially selects a plurality of broadcasts by determining an input time of the broadcast selection signal. And a tuner circuit 20 which receives the irradiation selection signal or the general broadcast selection signal and selectively amplifies and outputs only one frequency from a plurality of reception frequencies. do.

상기 조사선국장치(30)는 상기 출력되는 방송선택신호의 입력시간에 따라 조사선국선택신호 또는 일반방송선택신호인지를 판단하여 조사선국구동신호를 출력하거나 일반방송선택신호를 출력하는 조사선국판단부(32)와, 상기 조사선국구동신호를 입력받아 일정한 시간간격으로 방송주파수를 선택하는 조사선국신호를 발생시키는 조사선국신호발생부(31)로 구성된다.The irradiation selection device 30 determines whether the irradiation selection signal or the general broadcast selection signal is output according to the input time of the output broadcast selection signal, and outputs the irradiation selection drive signal or the general broadcast selection signal. 32, and an irradiation station signal generator 31 for generating an irradiation station signal for selecting a broadcasting frequency at a predetermined time interval by receiving the irradiation station driving signal.

상기 본 발명에 따른 방송선국장치는 다음과 같이 동작한다.The broadcasting station apparatus according to the present invention operates as follows.

시청자가 원하는 방송을 선택하여 방송선택버튼(10)의 숫자버튼을 누르거나 채널 업/다운 버튼을 일정시간(2초)이하로 누르면 조사선국판단부(32)에서는 일반방송선택신호를 튜너회로(20)에 출력한다. 상기 튜너회로에서는 입력된 다수개의 수신 주파수에서 선택된 하나의 주파수만을 동조하여 선택한후 증폭하고 상기 증폭된 신호를 중간주파 신호로 변환하여 출력한다.When the viewer selects a desired broadcast and presses the number button of the broadcast selection button 10 or presses the channel up / down button for a predetermined time or less (2 seconds), the irradiation selection judgment unit 32 sends a general broadcast selection signal to the tuner circuit ( 20). The tuner circuit tunes and selects only one frequency selected from a plurality of input frequencies, and then amplifies and converts the amplified signal into an intermediate frequency signal.

시청자가 방송선택버튼(10)의 채널 업/다운 버튼을 일정시간(2초)이상으로 누르면 상기 방송선택버튼(10)의 출력을 조사선국판단부(32)에서 조사선국선택신호로 판단하여 조사선국구동신호를 출력한다. 상기 조사선국구동신호를 입력받은 사선국신호발생부(31)는 일정한 시간간격으로 조사선국신호를 발생시킨다. 상기 조사선국신호를 입력받은 튜너회로(20)는 입력된 다수개의 수신 주파수를 일정한 시간간격으로 동조 선택한후 증폭하고, 상기 증폭된 신호를 중간주파 신호로 변환하여 출력한다.When the viewer presses the channel up / down button of the broadcast selection button 10 for more than a predetermined time (2 seconds), the output of the broadcast selection button 10 is determined by the irradiation selection decision unit 32 as the irradiation selection selection signal and is irradiated. Outputs the tuning drive signal. The diagonal station signal generator 31 receiving the irradiation station driving signal generates the irradiation station signal at a predetermined time interval. The tuner circuit 20 receiving the irradiation selection signal tunes and selects a plurality of inputted reception frequencies at a predetermined time interval, converts the amplified signal into an intermediate frequency signal, and outputs the amplified signal.

시청자가 원하는 방송이 출력될 경우 다시 한 번 채널 업/다운 버튼을 일정시간(2초)이상으로 누르면 조사선국구동신호의 출력이 중지되어 현재 출력되는 방송에서 선국동작은 중지하게 된다.When the viewer wants to output the broadcast, if the channel up / down button is pressed again for a predetermined time (2 seconds or more), the output of the irradiation tuning drive signal is stopped and the tuning operation is stopped in the currently output broadcast.

따라서 본 발명에 따른 방송선국장치는 특별한 조사선국버튼을 추가하지 않고 채널 업/다운 버튼을 누르는 시간만을 조정하여 다수개의 방송을 조사선택 할 수 있는 잇점을 가진다.Therefore, the broadcast tuning apparatus according to the present invention has an advantage of allowing the selection of a plurality of broadcasts by adjusting only the time for pressing a channel up / down button without adding a special irradiation tuning button.
