Description

Method for displaying country name by country code in televisions}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a country name marking method using a country code in a television, and more particularly, to a country name marking method using a country code displayed on an OSD using a country code that is prescribed and input.

Recently, with the improvement of television quality, the sharing of broadcasting channels around the world is progressing. To this end, recently, televisions switch various methods classified according to color methods by switching to correspond to each color method.

The terrestrial broadcasting television transmission system is classified into NTSC system, PAL system and SECAM system according to the color system. In the NTSC method, two chroma signals (I signal and Q signal) are generated by expressing the contrast of the screen by the luminance signal (Y signal) included in the composite video signal, and the color is transmitted using a carrier wave of a predetermined frequency. I use it. The PAL method uses a method of transmitting and detecting the phase of any one of the I report and the Q signal, which are chroma signals, by inverting the phase by 180 degrees for each scan line. Unlike the NTSC and PAL methods, the SECAM method transmits a color difference signal by FM modulation of a color carrier and requires two different color carrier carriers to simultaneously transmit two color difference signals. In addition, the typical difference according to the characteristics of the NTSC / PAL / SECAM method is the difference between the video band, the voice carrier and the color carrier, the NTSC video band is 4.2MHz, the voice carrier is 4.5MHz color The subcarrier is 3.579545 MHz. In the PAL method, the video band is 5 MHz, the voice carrier is 5.5 MHz, and the color carrier is 4.433618 MHz. Finally, the video band is 6MHz, voice carrier is 6.5MHz and color carrier is 4.40625MHz and 4.25MHz.

As such, televisions that can use various methods are being released, but there is a problem that immediate recognition of each broadcasting channel is difficult for viewers watching satellite broadcasts. That is, the recognition of which country's broadcast channel can be understood through language and the like. Even in Europe, a number of channels in neighboring countries are failing to recognize whether they are from one country or another.

This means that a television has a visible area and an invisible area. The visible area means a normal image processing area that can be viewed by a viewer, and the invisible area means an area that does not appear in the image processing area. In fact, the code designated for each country in the invisible region is textized, but the viewer cannot grasp this. As a result, there is a difficulty that the viewer can not immediately determine which country the current broadcast channel is watching.

Accordingly, an object of the present invention, if the user selects the country name display mode to solve the existing problems, includes displaying a country code prescribed in the OSD generation unit under the control of the microprocessor in a partial region of the CRT The present invention provides a method of writing a country name using a country code in a television.

According to the present invention for achieving the above object of the present invention, a country name display method using a country code in the television, the broadcasting channel corresponding to the selection of the broadcast channel is selected; Reading a country code of a corresponding broadcasting channel to read a country name matching the country code; Generating an OSD for the read country name; And displaying the country name in an area of the image processing means. At this time, it may be desirable to further include a message generating step of selecting whether to display the country name.

On the other hand, the television using the country code method using the country code of the present invention, the micro reads the country code for the selected broadcast channel, and generates a control signal for reading and displaying the country name corresponding to the read country code A processor; A memory storing a country name corresponding to the country code; And an OSD generator for controlling the display on the OSD in the region of the image processing means. At this time, the country-specific number and the country-specific number in the memory is divided by the corresponding broadcasting method of the broadcast method, and the data for the selectable broadcast channel for each country is also tabled in advance. Would be preferred.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a diagram schematically showing a basic configuration for performing a country name marking method using a country code in a television according to an embodiment of the present invention. Referring to FIG. 1, a basic configuration for carrying out the present invention includes an antenna 1, a tuner 2, a P / S separation unit 3, an image detector 4, an image processor 5, and a CRT driver. 6, the CRT 7, the microprocessor 8, the OSD generator 9, and the memory 10.

A broadcast signal of airwaves is received by the antenna 1, and the broadcast signal received by the tuner 2 controlled by the microprocessor 8 is tuned. The tuned broadcast signal is detected by the tuner 2 and then modulated, amplified and output into an intermediate frequency (IF) signal. The intermediate frequency (IF) signal is separated into an image intermediate frequency (PIF) and an acoustic intermediate frequency (SIF) by the P / S separation unit 3. The P / S separation unit 3 usually includes a surface acoustic wave (SAW) filter. When the image detection unit 4 detects and outputs an image signal from the image intermediate frequency PIF, the image processing unit 5 separates the detected image signal into RGB signals to the control signal of the microprocessor 8, respectively, and CRT. Output to the drive unit 6. Accordingly, the CRT driver 6 performs signal processing for each RGB signal region. The image is scanned by the CRT 7. Although the CRT 7 is described in the present invention, in the case of a digital television, for example, the X-axis driving and the Y-axis driving are controlled separately for the pixels arranged in a matrix form, thereby implementing a display. Since this is a conventional known process, a detailed description thereof will be omitted.

At this time, in order to carry out the present invention, a switching means for basically switching the broadcasting method is provided, and the current broadcasting signal is a three-broadcasting method based on the video signal output from the video detector (NTSC / PAL). / SECAM method) detects which broadcast method is the signal of the broadcast method to set the operation of the broadcast method. The broadcast method is selected in response to the switching control signal of the microprocessor (8), NTSC filter, PAL filter, SECAM filter, etc. corresponding to the broadcasting method are further provided.

On the other hand, the OSD generator 9, one of the most important elements for carrying out the present invention generates an input window on the OSD for the country information stored in the memory 10 to display on the part of the CRT 111 currently being broadcast. . The memory 10 matches and stores a country code and a country name corresponding to the country code.

That is, when the broadcasting channel selected by the user is selected and the country code inputted by the microprocessor 8 reads from the memory 10 and transmits the corresponding country name to the OSD generator 9, the OSD generator 9 The image is transferred to the image processor and displayed on a part of the CRT.

The process of the country name notation using the country code to be performed in the present invention using the television configured as described above will be described.

2 is a flow chart showing a country name notation using a country code according to an embodiment of the present invention. Referring to FIG. 2, when a user selects a broadcast channel using a remote controller or the like, the tuner searches for a corresponding frequency and tunes in the corresponding broadcast channel. Subsequently, video output of the corresponding broadcast channel is performed. At this time, the microprocessor 8 reads the text of the country code transmitted while the broadcast channel is received. The microprocessor 8 reads out a country name matching the country code from the memory 10. The read country name is transmitted to the OSD generator 9, and then the OSD generator 9 transmits it to the image processor to output an image control signal for display in the corresponding location area. Accordingly, the country corresponding to the CRT driving unit and the CRT is displayed in a partial region. Through this, the user can immediately identify which country's broadcasting channel.

Here, in the memory 10, the country-specific number and the country-specific number are divided by the corresponding broadcasting method among the three-broadcasting methods, and data on selectable broadcast channels for each country are preliminarily tabled. It is mad.

In addition, it would be desirable to set a button for displaying a country in a remote controller or the like so as to selectively use the button.
