The present invention relates to a method for automatically guiding a broadcast program of a TV, and more particularly, to a method for automatically guiding a broadcast program of a TV for automatically displaying a program of all broadcasts other than the broadcast currently selected and displayed on a screen for a predetermined time. It is about.

Broadcast channel selection in other video receivers, including TVs, has been manually selected via remotely controlled remote controls or key controls. In order to know the broadcast programs of all channels other than the broadcast currently displayed on the screen due to such a change of the broadcast channel, the preceding general video receiver may determine the broadcast program of each channel according to the number of channels currently being broadcast. This is very inconvenient because it has to be selected manually once.

Therefore, in the present invention, when a user wants to know a program currently being broadcast on all channels other than the currently broadcast channel, the user selects a 'scanning key' to broadcast the currently broadcast channel for a predetermined time. The purpose is to provide automatic program guidance.

Other objects and advantages other than the above-described objects and advantages of the present invention will be more clearly described through preferred embodiments of the present invention with reference to the accompanying drawings.

In the method for automatically guiding a broadcast program of a TV according to the present invention, when it is desired to know a current program broadcast through a broadcast channel other than the broadcast channel displayed on the screen, first, it is determined whether a 'scanning key' is input. And storing a channel number currently displayed on the screen when the 'scanning key' is input, changing the channel by increasing the channel to the next channel after the step, and Determining whether the channel changed in the step is the channel stored in the step; and in the step, if the channel changed in the channel change step is not the channel stored in the step, is the last channel among all broadcast channels currently receivable And determining if the changed channel is the last channel in the step. After changing to the first channel among the channels, it is determined whether the channel is a desired broadcast channel for which a program for broadcasting a normal broadcast signal is desired, and if the changed channel is not the last channel, the desired broadcast for which the program is to be immediately known. Determining whether the channel is a channel, and if it is a desired broadcast channel in the step, delaying the change of the broadcast channel so that the broadcast is displayed for a predetermined time; otherwise, returning to the channel increasing step; It is determined whether the 'scanning key' is input again, and when the 'scanning key' is not input, the process returns to the channel increment step, and when the 'scanning key' is input, the method returns to the first step.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram schematically showing an internal circuit of a general TV receiver applied to a TV program automatic guidance method according to the present invention. The TV receiver 100 includes a synchronization separator 10, a controller 20, and tuning. It consists of a circuit part 30 and a key array part 40.

The sync separator 10 receives vertical and horizontal sync signals, i.e., a composite video signal including a composite sync signal, and separates the vertical and horizontal sync signals into vertical and horizontal sync signals, and outputs them to the controller 20. Is provided. The controller 20 receives the vertical and horizontal synchronization signals provided from the synchronization separator 10 and counts the duty ratio thereof using a counter to determine whether a normal broadcast signal is received through the corresponding channel. In addition, when the 'scanning key' of the present invention is input from the key array unit 40, the control circuit 30 is generated by generating a control signal according to the output of the tuning circuit unit 30 and Each is provided to the key array portion 40.

The key array unit 40 is composed of keys for selecting various functions. In particular, a key input signal corresponding to the scanning key of the present invention is selected and provided to the controller unit 20.

The tuning circuit unit 30 tunes each channel currently being broadcast in response to a control signal from the controller 20 corresponding to the scanning key, and outputs the channel to be sequentially displayed for a predetermined time.

In other words, when the user presses the 'scanning key' of the key array unit 40 to provide the scanning key signal to the controller unit 20, the controller unit 20 sends the control signal accordingly to the tuning circuit unit 30. In response, the tuning circuit 30 selects, ie tunes, a broadcast signal of a corresponding channel while sequentially increasing the tuning channel, and outputs the signal to a signal processor (not shown), as is well known in the art. The signal processing unit processes and outputs a broadcast signal of each channel provided from the tuning circuit unit 30 so as to be displayed. Then, a screen such as a monitor, that is, a display unit (not shown) receives this and sequentially displays a broadcast signal for each channel until the next channel change is made.

At the same time, the sync separator 10 separates the vertical and horizontal sync signals from the composite video signal provided from the signal processor and provides them to the controller 20, and the controller 20 is tuned in the manner described above. It is determined whether a normal broadcast signal is loaded on the channel tuned and received by the circuit unit 30. At this time, if the normal broadcast signal is not loaded on the broadcast signal of the currently received channel, the controller unit 20 immediately generates a control signal for changing the channel to the next channel to the tuning circuit unit 30 so that the tuning circuit unit 30 Tunes the broadcast signal of the next channel to the currently tuned channel. On the other hand, if a normal broadcast signal is loaded on the broadcast signal of the currently received channel, the controller unit 20 does not generate a control signal for changing the channel for a predetermined time, thereby delaying the channel change and thereby broadcasting the broadcast signal of the currently tuned channel. To be displayed for a preset predetermined time.

Thereafter, i.e., after a predetermined predetermined time has elapsed, the controller unit 20 again generates a control signal to the tuning circuit unit 30 to tune the broadcast signal of the next channel.

After the scanning to the last channel is completed through this process, the controller unit 20 performs tuning until the tuning circuit unit 30 reaches the channel when the 'scanning key' is initially input from the first channel of the broadcasting channel. In order to perform the above-described process, the control signal according to the output signal of the synchronization separating unit 10 is provided to the tuning circuit unit 30.

Meanwhile, while performing this process, a broadcast program desired by the user is displayed, and when the user wants to watch it, the user can view the program by re-entering the 'scanning key' again.

2 is a flowchart illustrating a method for automatically guiding a broadcast program of a TV according to the present invention.

First, in step S10, a 'scanning key' is selected by the user to determine whether the key signal is input. In this case, when the 'scanning key' is not input, the flow is returned, and when the 'scanning key' is input, the flow proceeds to step S20.

Then, in step S20, the channel number currently being displayed, for example, the seventh channel, is stored.

After step S20, in step S30, the channel is increased to the next channel with a larger number than the current channel, for example, the seventh channel, and the flow proceeds to step S40.

At this time, in step S40, the increased channel, that is, the channel increased and increased in step S30, is compared with the channel stored in step S20, and the channel increased in step S30 is stored in step S20. If it is the same as the seventh channel previously broadcasted, the flow is returned, and if it is not the seventh channel, the flow proceeds to step S50 to determine whether the channel is the last channel among the channels currently being broadcasted. If the process proceeds to step S60 and changes the tuning channel of the tuning circuit unit 30 to the first channel of which the channel number is the smallest among the broadcasting channels, and proceeds to step S70. Proceed to S70.

Then, in step S70, it is determined whether the received broadcast channel is a broadcast channel that broadcasts a predetermined program, that is, a normal broadcast signal. At this time, if the received broadcast channel is not a channel for broadcasting a predetermined program, the process returns to step S30 and is performed again from the channel increasing step S30, and the received broadcasting channel is a broadcast channel for broadcasting the predetermined program. In the case where the process proceeds to step S80, the broadcast signal of the channel changed in step S30 is delayed to be displayed for a predetermined time.

When the step S80 is completed, in step S90 it is determined whether the 'scanning key' is input again, and when the 'scanning key' is not input, the flow returns to step S30 to perform the flow again and the 'scan' In case Ningkey is inputted, an operation is performed to return.

On the other hand, in the present invention, the channel increased in step S40, that is, the changed channel is the channel stored in step S20, for example, the seventh channel, means that the flow according to the present invention is performed to all channels. Indicates channel change and display is complete.

Further, in the present invention, the channel lower than the initially broadcast channel memorized in step S20 is the first channel after the execution to the last channel is completed, as described in steps S50 and S60. It returns and performs the flow for each channel sequentially.

In addition, whether or not the key is pressed in step S90 is an example of programming in consideration of the case where the user finds a program that he / she wants to watch in the previous step S80. In this case, when the 'scanning key' is selected again, Returning to S30), it is made by returning to the first step without increasing the channel.

As described above, according to the present invention, when the 'scanning key' newly added to the key array unit is used, the program currently being broadcast on all other channels other than the channel currently being broadcasted through the TV broadcast program automatic guide method program of the present invention. The automatic display of a predetermined time has the advantage that the user can receive a higher quality service.
