Abstract

텔레비전에서 시청자가 채널저장모드에서 채널 업/다운키를 조작하여 채널을 선국하면 PIP기능을 이용하여 선국한 채널과 다음 저장된 채널을 한 화면상에 출력시키는 텔레비전의 채널 선국장치및 그 방법이 개시된다. 본 발명은 PIP기능이 내장되고, 자동채널저장모드에 의하여 채널의 선국하는 채널선국방법에 있어서, 시청자가 다수의 방송채널을 선국하고, 저장하였나를 판단하여, 저장된 채널중에 현재 출력되는 채널을 확인하는 단계; 상기 단계후에 시청자가 채널 업키는 입력하였는지를 판단하고, 채널 업키가 입력되면 PIP모화면에 선국채널을 출력시킴과 동시에 저장채널중 PIP모화면에 출력되는 채널보다 상승된 채널을 PIP자화면으로 출력시키는 단계; 상기단계후에 시청자가 채널 다운키를 입력하였는지를 판단하고, 채널 다운키가 입력되면 PIP모화면에 선국채널을 출력시킴과 동시에 저장 채널중 PIP모화면에 출력되는 채널보다 하강된 채널을 PIP자화면으로 출력시키는 단계; 그리고, 상기 단계에서, 시청자가 채널선국키를 입력시키면 상기 채널선국키 입력확인단계 복귀하여 선국동작을 수행하는 단계로 이루어지는 것이다. 따라서 본 발명은 텔레비전에서 채널탐색에 소요되는 시간이 경감되어 다수의 채널을 저장하는 텔레비전에서 채널 선국의 효율성을 증가시키는 효과가 있다.When a viewer tunes a channel by operating a channel up / down key in a channel storage mode in a television, a channel tuning device for a television and a method for outputting a channel tuned using a PIP function and the next stored channel on one screen are disclosed. . According to the present invention, in the channel tuning method in which a channel is tuned by the automatic channel storage mode with a built-in PIP function, it is determined whether a viewer has tuned and stored a plurality of broadcast channels, so as to identify a channel currently output among the stored channels. Doing; After the above step, the viewer judges whether the channel up key is input, and when the channel up key is inputted, outputs a channel selected on the PIP screen and outputs a channel higher than the channel output on the PIP screen on the PIP screen. step; After the above step, it is determined whether the viewer inputs the channel down key, and when the channel down key is inputted, the channel is output to the PIP mode screen and the channel lowered than the channel output on the PIP mode screen among the stored channels is displayed as the PIP screen. Outputting; In this step, when the viewer inputs the channel tuning key, the channel tuning key input confirmation step returns to perform the tuning operation. Therefore, the present invention reduces the time required for channel searching in a television, thereby increasing the efficiency of channel selection in a television storing a plurality of channels.

Description

Channel Tuning Device and Method of Television

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 텔레비전의 채널 선국장치의 구성을 보여주기 위한 블럭도이다.1 is a block diagram showing the configuration of a channel selecting apparatus of a television according to the present invention.

Claims

A first tuner 20 and a second tuner 25, the first tuner 20 and a second tuner 25, which are connected to an output terminal of the antenna 10 for receiving a television signal transmitted from a broadcasting station and tune to a specific frequency; IF circuit 30, which is connected to an output terminal of the TV signal, detects, amplifies and outputs an intermediate frequency of the tuned television signal, and is connected to an output terminal of the IF circuit 30 to switch the output of a video signal and an audio signal in a television. A voice signal output unit 50 connected to an output terminal of the setting unit 40, a mode setting unit 40 to amplify and output an audio signal, and an amplification of a video signal by being connected to an output terminal of the mode setting unit 40 In the television having a video signal output unit 60 for outputting and a function setting unit 80 for receiving an operation signal of a viewer and having a built-in PIP function, when the channel selection function is input in the function setting unit 80, First tuner 20 and second tuner 25 and mode Outputs a control signal to the unit (40) is selected channel is output to the PIP display mode, characters received by PIP control unit 70 for controlling so that the output on the screen, the other channel; And a storage unit 90 connected to the control unit 70 for inputting and outputting data on a channel stored by the viewer.

In the channel selection method of a television channel having a built-in PIP function and tuning a channel by an automatic channel storage mode, the method includes: I) determining whether a viewer has tuned and stored a plurality of broadcast channels and checking the currently output channel among the stored channels. Steps 101-102; Ⅱ) After step I, it is determined whether the viewer inputs the channel up key, and when the channel up key is input, the channel is outputted to the PIP mode screen and the channel that is higher than the channel output on the PIP mode screen among the storage channels is displayed. Outputting steps 103-105; Ⅲ) After step I, it is determined whether the viewer inputs the channel down key, and when the channel down key is input, the channel is outputted to the PIP mode screen and the PIP channel is lower than the channel output on the PIP mode screen. Outputting to the own screen (106-108); And (iv) after step II to III, if the viewer inputs a channel tuning key, returning to step II and performing a tuning operation (109).
