A schematic configuration of a TV system of the prior art is first composed of a TV system control unit 3 which controls the entire TV system and outputs a TV broadcast signal on the screen, and a TV body configured to receive a user's selection signal. The external input signal processor 4 for processing, the OSD unit 5 for outputting an OSD (On Screen Display) signal under the control of the TV system controller 3, and the tuning control signal of the TV system controller 3 A tuner unit 1 for selectively outputting a broadcast signal, a TV image processor 2 for receiving and outputting TV image data and OSD data of the tuner unit 1, and outputting the image data to the TV image processor 2 It is largely comprised of the external display part 6 which displays an output signal to the exterior.

The TV system configured as described above is controlled by the TV system control unit 3 which controls the whole of the TV system. When the user inputs a control signal such as TV o / off and channel selection, the user inputs a selection control signal using a remote controller. The external input signal processing unit 4 processes this, and the TV image data selected by the tuner unit 1 and the OSD data of the OSD unit 5 are processed by the TV image processing unit 2 according to the processed signal. Displayed in section 6.

In such a TV system, various services have been attempted using various information including broadcast information transmitted between program signals.

For example, there is KBPS (Korean Broadcasting Program System) in Korea.

KBPS refers to a system that transmits various information data about a program by carrying about 2 bytes per horizontal section in a vertical synchronization section of a composite video signal.

A broadcast method using broadcast information data includes a VPS (Video Programmable System) and a PDC (Program Delivery Code).

The VPS mainly includes information on broadcast programs, and the PDC includes program information and time information.

Such a conventional TV system has the following problems.

When a channel is deleted in the edit mode at the time of channel classification according to the ATS operation, a channel related to time correction may be deleted, and the user must perform the ATS function again.

This increases the user's inconvenience and the possibility of malfunction, thereby lowering the reliability of the product.

The present invention has been made to solve such a problem of the TV system of the prior art, TV channel in the edit mode to selectively delete the channel for time correction when the channel classification using PDC / VPS data The purpose is to provide a deletion method.

The TV channel deletion method in the editing mode of the present invention, which allows selective deletion of a channel for time correction when classifying a channel using PDC / VPS data, changes the channel editing mode when the TV system is turned on by a user's selection. Executing; Detecting a PDC code by determining a channel delete key when a channel delete key is input by a user in a channel edit mode; Determining whether a country code and a broadcasting station ID match in the detected PDC code; Performing a channel deletion function if the country code and the station ID do not match, and displaying the warning data for a time for which the channel to be deleted is a channel related to time correction if the country code and the station ID match; Determining whether there is a separate key input for canceling channel deletion for a predetermined time, and if there is a separate key input, stopping the channel deletion function, otherwise deleting the corresponding channel.

Hereinafter, a TV channel deletion method in the edit mode according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic configuration diagram of a TV system for performing an ATS operation using broadcast information data.

Broadcasting methods using broadcast information data may be classified into a VPS (Video Programmable System) and a PDC (Program Delivery Code).

The VPS transmits broadcast program information data on a 16th line existing on an equalized pulse section that does not appear on the screen among broadcast signals, and receives the VPS signal from a receiver (TV / VCR). It is possible to recognize the information of the broadcast signal being received.

In addition, the PDC is developed and used in Europe, such as Germany, the United Kingdom, Australia, and the difference from the VPS transmits the Teletext information data, and similarly, the teletext data information is loaded on the equalization pulse section. To give.

At this time, the 16th line on the equalization pulse interval is not used because of the relationship with the VPS.

Here, the teletext information data of the PDC includes program information and visual information.

FIG. 2 is a block related to performance of an operation mode using broadcast information data. The microcomputer 20 controls a TV function, and inputs data of the corresponding signal according to a preset mode. PDC / VPS decoder 22 for storing the data in the microcomputer 20 or reading from the microcomputer 20, and receiving the tuning data from the microcomputer 20 and received through the antenna ANT. Tuner 21 for tuning to any one of the broadcast radio waves and applying the video signal formed at that time to the PDC / VPS decoder 22, and the tuning data of the program, and the microcomputer 20 when the program is changed. The memory unit 23 stores the data so that the data can be read.

The PDC / VPS data detection operation in the TV system configured as described above is as follows.

In an ATS (Auto Tuning System) operation using PDC / VPS data in a TV system, the microcomputer 20 applies the data to the tuner 21 while gradually increasing its value from the lowest value of the tuning data.

The tuner 21 receives data from the microcomputer 20 and tunes the corresponding frequency, and sends the video signal formed at this time to the PDC / VPS decoder 22 through a data transmission line. AFT data is output to the microcomputer 20.

The PDC / VPS decoder 22 detects PDC / VPS data from a video signal input from the tuner 21 and stores the PDC / VPS data in an internal register so that the PDC / VPS decoder 22 can read at any time from the microcomputer 20. Make

In addition, the microcomputer 20 has the H-syncnose and AFT data of the input video, controls the value of the tuning data, and finds the right tuning point of the received broadcast.

At this time, the microcomputer 20 controls to selectively delete the channel related to time correction at the time of channel classification using the PDC / VPS data.

That is, it is determined whether the country code of the PDC data and the broadcasting station ID match, and the channel deletion or channel deletion according to the user's selection is performed according to the match.

Such a TV system performs various functions by using information data transmitted between video signals.

The most representative of these is the ATS function.

Another function is the ACSS (Auto Clock Setting System) function, which automatically matches the time of the broadcasting station with the time of the TV system.

In the ACSS operation, the microcomputer 20 transmits the clock data through the clock mode such that the PDC / VPS decoder 22 stores the clock data in an internal register.

The PDC / VPS decoder 22 detects only data corresponding to a clock from an input video signal and stores the data corresponding to a clock in an internal register.

After the operation of storing the data corresponding to the detected clock in the internal register is finished, the microcomputer unit 22 reads the clock data stored in the internal register of the PDC / VPS decoder 22 to set or correct the current time.

The TV channel deletion method in the edit mode in the TV system according to the present invention will be described below.

3 is a flowchart illustrating a method of deleting a TV channel in an edit mode according to the present invention.

The TV channel deletion method in the edit mode of the present invention allows the deletion of a channel related to time correction at the time of performing the channel delete function in the edit mode by the user's selection. The processing sequence is as follows.

First, the TV system is turned on by the user's selection (301S), and when the execution of the ATS operation is completed, the channel editing mode is executed (302S).

If the channel deletion key is input by the user's selection in the channel editing mode (304S), it is determined (304S) and the PDC / VPS code is detected (305S).

Then, it is determined whether the country code and the broadcasting station ID match in the detected PDC code (306S).

Here, if the country code and the station ID do not match, the channel deletion function is performed (310S). If the country code and the station ID match, the time for setting data to inform the user that the channel to be deleted is a 'time correction channel' is set. (307S)

In operation 308S, if there is a separate key input for canceling channel deletion, the channel deletion function is stopped.

If there is no separate key input for canceling channel deletion within the set time, the channel deletion function is performed (309S).

As described above, in the ATS operation using the PDC / VPS data, it is determined whether the country code of the PDC data and the broadcasting station ID match, and the channel deletion is performed according to the user's selection according to the match.

The TV channel deletion method in the edit mode according to the present invention, when the channel is deleted in the edit mode at the time of channel classification, the deletion of the channel related to the time correction proceeds by the user's selection so that the condition of the channel related to the time correction Prevent deletion
