Description

Station name recognition method according to channel movement in edit mode

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TV system. In particular, when there is a channel shift in the edit mode, the station name recognition is performed according to the channel shift in the edit mode to improve user convenience by appropriately updating the station name using PDC / VPS data. It is about a method.

One of the functions generally used in TV systems is the Automatic Tuning System (ATS).

The ATS function is one of the basic functions used in a TV system. The ATS function automatically tunes a channel using an ATS code assigned to each broadcasting station.

Broadcasting stations that do not implement the ATS function have also registered the ATS code in the broadcasting associations of the region.

Hereinafter, a TV system according to the related art will be described with reference to the accompanying drawings.

1 is a schematic configuration diagram of a TV system of the prior art.

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.

In the TV system of the prior art, there is no function of detecting the station name properly in the automatic setup mode and detecting the station name properly when there is a channel shift in the edit mode. It was difficult for the user to recognize whether or not the station.

That is, even though the channel moves frequently in the edit mode, there is a problem in that an up date of a station name having a representative character among various broadcast information is not properly made.

The present invention has been made to solve the problems of the conventional TV system, and when there is a channel shift in the edit mode, the user can conveniently update the broadcasting station name using PDC / VPS data to improve user convenience. An object of the present invention is to provide a method for recognizing a broadcasting station name according to channel movement in a mode.

If there is a channel shift in the edit mode, the station name recognition method according to the channel shift in the edit mode that improves the user's convenience by appropriately updating the station name using the PDC / VPS data can be edited and edited in the edit mode. And continuously determining whether there is a channel movement while performing a program editing function such as detecting and storing and displaying a broadcast station name in the PDC code of the selected channel when there is a channel movement in the edit mode. It is done.

Hereinafter, a method of recognizing a broadcasting station name according to channel movement in an 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 centered on a reception block of 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 the system to detect the channel movement in the edit mode using the PDC / VPS data and to accurately recognize the data related to the broadcast station name.

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.

Such a method of recognizing a broadcasting station name according to channel movement in the edit mode according to the present invention will be described below.

3 is a flowchart illustrating a method for recognizing a broadcasting station name according to channel movement in an edit mode according to the present invention.

If the TV is turned on by the user's selection (301S), it is determined (302S) to determine whether the current operation mode is the edit mode (303S).

Subsequently, it is determined whether there is a movement of the channel while performing a program editing function such as image editing or sound editing in the editing mode.

If there is a channel shift in the edit mode, the PDC code of the selected channel is detected (305S).

When the detection of the PDC code is completed (306S), the station name is detected from the detected PDC code, and stored and displayed. (307S)

The station name update continues according to the channel movement in the edit mode. (308S)

In this way, if there is a channel shift in the edit mode using the PDC / VPS data, it is detected using the PDC data to accurately recognize and store the name of the broadcasting station of the current channel.

The broadcasting station name recognition method according to the channel movement in the edit mode according to the present invention has the effect of accurately detecting the channel movement in the edit mode to update the broadcasting station name to increase user convenience.
