The present invention relates to a channel tuning method, and more particularly, to a sequential channel tuning method for displaying a screen of each channel selected for a predetermined time to tune a channel. In a video apparatus such as a television or a video cassette recorder, the conventional channel tuning method tunes a desired channel by pressing the channel number to be tuned. Therefore, in order to select a channel to be watched, a lot of troublesome manual work is required and accordingly, it is inconvenient to grasp the contents being broadcast for each channel.

That is, in order to grasp the contents of a program broadcast in other channels while the user is currently watching a predetermined channel, the channel up / down attached to the remote controller or the main body of the video device is tuned until the channel where the desired program is broadcast is tuned. The channel (Channel UP / DOWN KEY) was pressed repeatedly to select the channel of the broadcast program to watch. As described above, in the conventional channel tuning method, if a user wants to watch a desired program by selecting another channel from the channel currently being watched, the channel to be selected can be tuned by pressing a key for selecting each channel. In addition, in order to grasp the contents of the program being broadcast for each channel, a separate circuit such as a multi-screen display circuit had to be added. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to select a channel sequentially by pressing a channel index key, display a program being broadcast on the selected channel for a predetermined time, and display the channel index key by the user. When is pressed again, the present invention provides a sequential channel tuning method for facilitating channel tuning by tuning the currently displayed channel.

A feature of the present invention for achieving the above object, in the method of sequentially tuning each channel stored from the minimum channel to the maximum channel by the channel index key attached to the remote control or the main body, by the channel index key A first step of determining whether to input a channel selection signal; A second step of tuning a minimum channel when it is determined that the input of the channel tuning signal is determined as the result of the first step; A third step of displaying a broadcast program of the minimum channel selected in the second step on a screen for a predetermined waiting time; A fourth step of tuning the channel being displayed in the third step if the signal for the channel index key is input again within the predetermined predetermined waiting time of the third step; And a fifth step of performing the process for each channel stored from the next channel to the maximum channel after the minimum channel if the signal for the channel index key is not input again within the predetermined predetermined waiting time of the third step. do. Hereinafter, with reference to the accompanying drawings will be described in detail the present invention. 1 is a block diagram showing the configuration of a channel tuning apparatus according to the present invention. The channel tuning apparatus shown in FIG. 1 includes a remote controller 10 that provides a signal for a channel index key pressed by a user, and a key signal that receives and provides a signal for a channel index key provided from the remote controller 10. When a signal for a channel index key provided by the receiver 110 and the key signal receiver 110 is provided, a control signal for performing a tuning operation for each stored channel and displaying a program of the tuned channel on a screen for a predetermined time is provided. Predetermined broadcast program of the channel selected by the channel selection unit 120 under the control of the microcomputer 150, the channel selection unit 120 to tune the corresponding channel under the control of the microcomputer 150, the microcomputer 150 The display unit 140 to display on the screen for a time, and the timer 130 for checking the screen display time of the display unit 140. A detailed description of the operation of the channel tuning apparatus according to the present invention configured as described above is as follows.

The key signal receiving unit 110 receives a signal for a channel index key attached to the remote controller 10 or the main body 100 and provides the signal to the microcomputer 150. At this time, when the signal for the channel index key is provided from the key signal receiving unit 110, the microcomputer 150 performs channel tuning operations from each channel stored in the internal memory (not shown), that is, the minimum channel to the maximum channel. Perform. That is, when the signal for the channel index key is provided from the key signal receiving unit 110, the microcomputer 150 controls the channel selecting unit 120 to perform channel tuning from the minimum channel stored in the internal memory. The display unit 140 controls the program of the channel selected by the tuner 120 to be displayed on the screen for a time set in the timer 130. Accordingly, the channel selecting unit 120 selects the minimum channel under the control of the microcomputer 150, and the display unit 140 selects the channel for the predetermined time set in the timer 130 under the control of the microcomputer 150. The program of the channel selected by the local unit 120 is displayed on the screen. In this case, the screen display time of the tuned channel is preset in the timer 130. When the time count control signal is provided from the microcomputer 150, the time count is started. In response, the microcomputer 150 outputs a channel tuning signal for the next channel. That is, when the signal for the channel index key is again provided by the key signal input unit 110 before the screen display time set in the timer 130 has elapsed, the microcomputer 150 selects the channel selection unit to tune to the channel currently displayed on the screen. If the signal for the channel index key is not provided, the channel selector 120 is controlled to sequentially tune the next channel of the current channel selected in the internal memory. 2 is a flowchart for performing a sequential channel tuning method according to the present invention, which will be described in detail with reference to the block diagram shown in FIG. The microcomputer 150 determines whether a signal for the channel index key is input from the key signal receiver 110 in step 100. As a result of the determination, when a signal for the channel index key is input from the key signal receiving unit 110, the flow proceeds to step 200, and ends if the signal for the channel index key is not input from the key signal receiving unit 110. The microcomputer 150 proceeds to step 200 and proceeds with the channel sequential tuning mode for performing the tuning operation from the minimum channel among the channels stored in the internal memory. At this time, the microcomputer 150 outputs the minimum channel tuning control path to the channel selecting unit 120 to tune the minimum channel (step 300).

Accordingly, the channel selector 120 tunes the minimum channel corresponding to the minimum channel tuning control signal provided by the microcomputer 150, and accordingly, the microcomputer 150 proceeds to step 400 and is preset in the timer 130. The predetermined screen display time, for example, delays the tuning operation of the next channel, i.e., the next channel, for 5 seconds, and displays the program of the currently tuned channel, i.e., the minimum channel, on the screen.

At this time, the microcomputer 150 proceeds to step 500 and determines whether the signal for the channel index key is input again from the key signal input unit 110 within the program display time of the tuned channel, that is, within 5 seconds. As a result, if a signal for the channel index key is input from the key signal input unit 110 within 5 seconds, the program of the channel currently displayed on the screen is tuned (step 600), and from within 5 seconds from the key signal input unit 110. If a signal for the channel index key is not input, the process proceeds to step 700 and the channel selector 120 is controlled to perform the tuning operation of the channel next to the minimum channel currently selected. On the other hand, the microcomputer 150 sequentially performs the above process for each channel, and then returns to the 300th step if the channel tuned by the channel selecting unit 120 is the maximum channel (step 800). That is, the microcomputer 150 selects channels sequentially by repeating the above process for each channel stored in the internal memory. As described above, in the sequential channel tuning method according to the present invention, when a signal for the channel index key is provided from the remote controller or the main body, the channel tuning operation is performed sequentially from the minimum channel and the program of the tuned channel is performed for a predetermined time. If the signal for the channel index key is provided again within the time displayed on the screen, the channel currently displayed on the screen is tuned. If the signal for the channel index key is not provided, the next channel tuning operation is performed. By repeating the above process for the next channel, the channel can be tuned more easily than the conventional channel tuning process of tuning each channel using the channel up / down keys.
