BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an on-screen circuit in a television receiver, and more particularly to an on-screen scroll circuit and a method in a television receiver having a scroll function for allowing an on-screen display device to allow a consumer to compare and select a current program. will be.

The on-screen function of the conventional television receiver is adapted to display characters on a given block of the TV screen. However, if the number of characters is large, the on-screen characters are written in units of pages. For example, when there are four programs in the 10th time in KBS1, all of them cannot be displayed on one screen as shown in FIG. 3 (3a), so they are divided and displayed on the screen as shown in FIG. However, the program is displayed on one screen as shown in FIG. 3C to 3D in FIG. 3C, so that it can be changed from FIG. 3A to FIG. 3B and compared with other programs. There is no problem.

Accordingly, an object of the present invention is to provide a method and a circuit for allowing a user to compare and select a current program with another program by placing a scroll function on the on-screen function.

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

1 is a view referred to for explaining an embodiment of the present invention, a font memory 106 storing font data for on-screen characters, an OSD memory 104 storing OSD control data, and A CPU which receives input from an external input terminal 107 and reads font data for each character from the font memory 106 so as to display the font data at a desired position of on-screen data output from the OSD memory 104. And an OSD controller which controls to provide luminance (Y) and color (C) signals to a display unit by reading data output from the OSD memory 104 according to a desired position output from the CPU 100. It consists of 102.

2 is a flowchart according to the present invention, which includes a first step of checking which broadcast program and at what time (3) program location the current cursor is located, and the specific second of what time in the first step; A second step of checking whether another program of the present time is being broadcast when there is a kerus in the program, and a third step of displaying the second-fourth program on the screen and the position of the chercher in the third position when the second step is present. In the third process, if there is no other program after the current program, if the program is finished, the third to fifth programs are displayed on the screen, and the cursor position is performed by the fourth process to allow the third position.

4 is an exemplary view of OSD display in the present invention.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4, and the present invention has a cursor in the 10th time of KBS1, as shown in FIG. If the wind blows in 10 minutes or TV novels in 30 minutes, the cursor is displayed to display 3 programs in the designated block when the wind blows in 10 minutes. To be displayed as

To this end, the central processing unit 100 checks the state of the OSD controller 102 from the input of the external input terminal 107, checks which broadcaster the current cursor is at which position, and at what time in step (2b). Check if there is a cursor position in the third program of. In step (2c), check whether there is another program in the current time. When there is another program in the current time in step (2c), the OSD controller 102 reads the data in the font memory 106 to determine the OSD memory 104. The OSD controller 102 is controlled according to the control program to display the second, third, and fourth programs on the screen in step 2d, and to position the cursor 3rd as shown in FIG. In step 2e, the CPU 100 checks whether there is another program after the current program. When in step (2c), the third, fourth, and fifth programs are displayed on the screen in step (2f), and the position of the cursor is placed in the third position.

As described above, many programs can be displayed only in the 10th age of KBS1 without affecting other parts, and there is an advantage that it can be used in DBSs and teletexts that have more OSD information than in existing TVs.

Claims (3)

1. An OSD method of a television receiver, comprising: a first step of checking which broadcast program and at what time of a particular program position a current cursor is located in the television receiver; and the specific second program at what time in the first step; A second step of checking whether another program of the current time zone is being broadcast when there is a chercher, and a second step of displaying a second-fourth program on the screen when the second step is present, and the chercher's position And, if there is no other program after the current program in the third process, displays the third to fifth programs on the screen, and moves the cursor to the third position by positioning the third to fifth positions. The method of claim 1, wherein the display of the program on the screen is scrolled to allow comparison with other programs. In the OSD circuit of a television receiver, first detection means for detecting which broadcast program position is located at which specific program position and at what time, and the third program of which time is used in the first detection means. Second detection means for detecting whether another program in the current time is being broadcasted, and a second-fourth program on the screen when the second detection means is present, and the position of the cursor to the specific first position. Means and a second cursor position control means for displaying a third to fifth program on the screen and ending the third position if there is no other program after the current program in the first cursor position control means. On-screen scroll circuit in television receiver.
