BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver (hereinafter referred to as a TV) receiver for receiving programs transmitted from various broadcasting stations, and in particular so that the name of a broadcasting station transmitting a program that is currently being watched (or received through a channel of a tuner) can be easily known. A display station name display apparatus.

Currently, various TV stations offer various programs (or broadcasts), but as the information needs of viewers are diversified, cable TVs (CATV), which provide local information in the future, are expected to be activated. do. In this way, when CATV broadcasting is activated, the number of broadcasting stations will increase, and when the number of broadcasting stations increases, it becomes difficult to determine which broadcasting station the program currently being viewed is provided only by the function of on-screen display of the channel number when changing the currently used channel. .

That is, when the number of broadcasting stations is small, the viewer can easily remember the broadcasting station name corresponding to the channel number. As described above, only the channel number displayed at the time of changing the channel can be enough to know the broadcasting station name. In this case, since it is difficult for a viewer to memorize the broadcasting station name corresponding to the channel number, it is difficult to determine the broadcasting station name only by the displayed channel number.

Accordingly, an object of the present invention is to display a broadcast station name that displays a broadcast station name using an On Screen Display (OSD) function so that viewers can easily know which broadcasting station the program being watched is provided in the TV receiver. To provide a device.

In order to achieve the above object, an apparatus according to the present invention comprises: input means for applying a control command of a user; When a predetermined channel is selected through the input means, the station name corresponding to the channel is detected, and the station name is displayed to continuously output the display control signal for the channel number and the station name until the predetermined control signal is applied through the input means. Control means; An on-screen generator for outputting on-screen data of the display control signal output from the broadcast station name display control means as an analog signal represented by a signal level of red, green, and blue; A video signal processor which processes the received video signal to be displayed and outputs it as an analog signal represented by a red, green, and blue signal level, and outputs the on-screen data output from the on-screen generator and the video signal output from the video signal processor. And an overlapping mixer and a CRT driver for driving the CRT so that the signal output from the mixer can be displayed on the CRT.

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

1 is a block diagram of an apparatus for displaying a name of a broadcasting station according to the present invention, in which a video signal of a composite video signal (NTSC signal) tuned in a tuner (not shown) is displayed through a not shown CRT (Cathode Ray Tube). The image signal processing unit 10 processes and outputs the signal as red, green, and blue signal levels, an input means 1 for applying a user's control command, and a control signal applied through the input means 1. Broadcast station name display control means (2) for setting a channel number that can be received and a broadcast station name corresponding to the channel number, and controlling the display of the broadcast station name of the program currently being corrected based on the set data, and the broadcast station name display control means (2). The on-screen generator (4) and the video signal processor (10) outputting the on-screen data read by the control signal output from the red, green, and blue signal levels; A mixer 6 for mixing on-screen data output from the screen generator 4, and a CRT driving unit for driving a CRT (not shown) by mixing a video signal and an on-screen data output from the mixer 6; It consists of (8).

The operation of FIG. 1 configured as described above is performed as follows.

First, the input means 1 is directly operated by the user, and consists of a remote control (REMOCON) or a control key located on the front panel, if any key is controlled by the user, data on the controlled key ( Or user's control command). The output data is transmitted to the broadcast station name display control means (2).

The broadcasting station name display control means (2) is implemented as a microcomputer that preprograms the broadcasting station name according to the channel number, but the user can directly set the broadcasting station name corresponding to the channel number (or broadcasting channel) using the input means (1). It can also be implemented as a microcomputer.

In other words, in the case of implementing a microcomputer in which a broadcasting station name corresponding to the channel number is programmed in advance, the broadcasting station name display control means 2 is programmed so that the display control signal for each channel number and the broadcasting station name are associated with each other. For example, CH9 indicates KBS1, CH11 indicates MBC, CH6, and so on. The display control signals are linked to each other so that the user selects a predetermined channel through the input means 1. The control means 2 detects the broadcast station name corresponding to the selected channel and simultaneously outputs the display control signal for the selected channel and the display control signal for the corresponding broadcast station name. For example, when the user controls 'CH 6' through the input means 1, the broadcast station name display control means 2 detects the broadcast station name 'SBS' corresponding to 'CH 6', and controls each display. Output the signal at the same time. The output display control signals are transmitted to the on-screen generator 4.

On the other hand, when the broadcasting station name display control means 2 is implemented by a microcomputer programmed so that a user can input and change the broadcasting station name corresponding to the channel number (or broadcasting channel), the broadcasting station name corresponding to the channel number Prior to being set in the broadcast station name display control means 2, if a predetermined channel is selected through the input means 1, only the posi- tion control signal capable of displaying the number of the selected channel is output. However, when a control signal for setting a broadcast station name corresponding to the channel number is applied by the user, a message for inputting the broadcast station name (for example, the cursor is displayed at a predetermined position on a CRT not shown to display the broadcast station name) is displayed. After outputting), the station name input through the input means 1 is set to correspond to the selected channel number, and when the setting completion signal is applied through the input means 1, the station name display control means 2 In the above-described setting process, the channel numbers matched with the broadcasting station names are matched with each other, and if a predetermined channel is selected through the input means 1, the display control signal for the channel number is changed as in the former case. The display control signal for the corresponding broadcast station name is output to the on-screen generator 4. In this case, the broadcast station name display control means 2 may continue to display the broadcast station name corresponding to the above-described channel number on the CRT (not shown) until the display release signal or other control signal is applied through the input means 1. Output a control signal.

The on-screen generator 4 is composed of a room table containing various letters, numbers, and special symbols. When the display control signal of the channel number and the station name is transmitted from the station name display control means 2, the on-screen generator 4 is built in the room table. The data is converted into an analog signal represented by R, G, and B color levels in accordance with the synchronization signal applied from the synchronization separator (not shown), and output to the mixer 6. Here, the on-screen is a function to display an image composed of a picture, such as a character or a figure, superimposed on a TV program screen or to display the picture independently by a predetermined control, such as a broadcast reception channel, a volume, a current time, and the like. It is used to display. In particular, as the functions of the TV receiver become more and more diverse, various types of on-screen data are pre-stored in the on-screen generator 4 so that the user can easily recognize each function state. By using the Custom Design method to produce the software of Mycom according to the specifications of the company, it is possible to store a wide variety of data to perform unique functions.

The mixer 6 processes the video signal received by the video signal processor 10 into a video signal that can be displayed on a CRT (not shown), and outputs the video signal and the channel number and broadcast station name output from the on-screen generator 4. The on-screen data for the two signals are superimposed and transmitted to the CRT driver 6.

The CRT driver 6 drives the CRT so that the mixed image and the on-screen data can be displayed on the CRT (not shown). The channel and broadcast station names displayed on-screen as described above are continuously displayed on the CRT until a predetermined control signal is input by the user as described in the station name display control means 2.

As described above, the present invention enables the display of the broadcasting station name corresponding to the broadcasting channel number of the program currently being viewed by using the on-screen display function, so that the name of the broadcasting station providing the correcting program can be easily known. There is.
