Abstract

The present invention relates to a method of channel erasing of V-Cal suitable for allowing a user to erase a channel to be erased among a plurality of television channels. When the channel clear message is displayed on a blue back screen according to the related art, a plurality of channels are displayed. Since the actual screen is not visible when the user wants to erase, there is a cumbersome drawback of seeing the actual screen according to the desired channel and entering the channel cree guide screen in the menu screen and repeating the operation of deleting the corresponding channel. When entering the screen, after displaying the actual screen for every channel among the plurality of television channels, the channel to be erased can be easily erased by displaying a channel erase guide on the blue back screen, thereby improving the above-described drawbacks.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a channel erasing method of a video cassette recorder (VCR), and more particularly, to a channel erasing method suitable for allowing a user to erase a channel to be deleted among a plurality of television channels.

Briefly, the principle of VRC is as follows.

We can easily call it VSI, but it was originally called Video Cassette Recorder, which is the correct name. In Korean, it can be called 'self-recording playback'.

It is a device that records video signals from the outside and records them on tape through the head of VRC.

In this case, the head is a kind of electromagnet, which causes a change in the magnetic force according to the electric change, and the head which emits a magnetic signal is recorded by contacting the tape.

At this time, the tape is iron powder coated on the vinyl, the iron powder is magnetized according to the change of the magnetic force of the head.

You can also select the recording speed of VRF.

The recording speed can be divided into standard speed (SP mode) and triple speed (SLP mode or EP mode: two hours of tape can be used for six hours).

If you don't have important recordings, you can record at three times the speed, but the video quality is lower than standard speed recording.

In addition, there are two types of home VRs, β type and VHS (Video Home System) type. The basic concept of the two types is the same, and the tape used is 1/2 inch wide.

In this regard, according to the conventional channel clearing method of VRC, after the Auto Channel Search, a screen called Channel Clear is provided in order to enable the user to delete the channel that he does not want. .

As such a channel cree screen, a channel cree guide is put on a blue back screen and a channel cree guide is displayed on an actual screen according to a corresponding channel so that a user can select a channel to be erased.

However, these conventional techniques have the following drawbacks.

First, when the channel cree guide is displayed on the blue back screen, when the user wants to erase a plurality of channels, the real screen is not displayed. Therefore, the user can enter the channel cree guide screen in the menu screen and delete the corresponding channel. There is a cumbersome drawback that must be repeated.

Second, in the case of displaying the channel cree guide on an actual screen, if the channel to be erased is bad, the sync signal is mixed with noise, and the channel cree guide is also displayed poorly. It is difficult to accurately recognize the channel.

The present invention has been made to solve the drawbacks of the prior art, and when entering the channel clear screen through the menu screen, after displaying the actual screen for every channel of the plurality of TV channels, the channel clearing instructions on the blue back screen It is an object of the present invention to provide a method for erasing a channel of a VCC that can be displayed.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

Referring to FIG. 1, FIG. 1 is a block diagram showing an embodiment of a VRC to which a VRC channel erasing method according to the present invention can be applied, and a key input unit for inputting a key to select a desired function of a VRC. The microcomputer 20 receives a plurality of TV broadcast signals through a micom 20 that controls a corresponding function according to a key input of the key input unit 10, and a preset antenna. Tuner 30, which tunes and outputs a TV broadcast signal of a specific frequency desired by the user, and outputs the intermediate frequency processing, and receives the output of the tuner 30 to the screen under the control of the microcomputer 20. And an image processing unit 40 for converting and outputting a signal for display and a display unit 50 for receiving an output of the image processing unit 40 and displaying an image according to a corresponding channel on a screen. .

The present invention thus made will be described with reference to FIG.

First, the key input unit 10 is composed of a remote control or a key plate key input by the user to select the desired function of the V-Cal, the microcomputer 20 so that the corresponding function is made according to the key input of the key input unit 10 Control each part.

Next, the tuner 30 receives a plurality of television broadcast signals through a predetermined antenna, tunes the TV broadcast signal of a specific frequency desired by the user under the control of the microcomputer 20, and outputs the intermediate frequency processing.

At this time, intermediate frequency processing will be performed using a predetermined local oscillator.

The image processing unit 40 receives the output of the tuning unit 30, converts the signal into a signal for display on the screen under the control of the microcomputer 20, and outputs the output of the image processing unit 40. It is applied to display the image according to the channel on the screen.

2 is a flowchart showing step by step an embodiment of a method of channel erasing of VR in accordance with the present invention.

First, when the channel erasing screen is selected, the actual screen of the corresponding channel is displayed for a predetermined period of time, for example, for 3 seconds, and then the channel erasing guide is displayed on the blue back screen (100, 110).

Next, if the channel is erased by determining whether the channel is erased or the channel number is changed, the channel is erased and the next channel is selected to display the actual screen of the channel for a certain period of time, for example, 3 seconds, and then the blue back screen is displayed. If the channel clearing announcement is displayed and the channel clearing is to be continued, the process returns to step 120 (120, 130, 150).

In addition, in the case of changing the channel number in the above-described step 120, after changing the channel and selecting the corresponding channel, for example, the actual screen of the corresponding channel is displayed for a certain period of time, for example, for 3 seconds, the channel erasure guide message is displayed on the blue back screen. If it is displayed and wants to continue channel erasing, the process returns to step 120 (140 and 150).

As described above, when the user enters the channel clear screen through the menu screen, the present invention displays a real screen for every channel among a plurality of TV channels, and then easily displays the channel to be erased by displaying a channel erase guide on the blue back screen. It has the effect of erasing.

Claims (2)

Displaying a channel erase message on a blue back screen after displaying the actual screen of the corresponding channel for a predetermined period when the channel erase screen is selected; If the channel is deleted by determining whether the channel is deleted or the channel number is changed, the channel is deleted and the next channel is selected to display the actual screen of the channel for a certain period of time. Returning to step 120 if it is desired to continue (120, 130, 150); In the case of changing the channel number in step 120, after changing the channel to select the corresponding channel to display the actual screen of the corresponding channel for a certain period of time, and then to display the channel clearing message on the blue back screen and continue the channel clearing. And a step (140, 150) of returning to the step (120). The method of claim 1, wherein the predetermined period of time is 3 seconds.
