In order to achieve the above object, there is provided a method of displaying a visual display of a character display system, comprising the steps of: receiving input character information data, deciphering the received character information data and storing the decoded data in a memory S1); A second step (S2) of reading data from the memory when an on-screen display (OSD) display command is input; A third step (S3) of determining whether the data read in the second step is an on-screen display mode related to time; Screen display mode if the mode is not related to the time in the third step and calculates the start time and the end time of the program and the start time and the end time of the program in the related on- (S4); A fifth step (S5) of determining a vertical position of each on-screen display line based on the start time and the end time calculated in the fourth step; And a sixth step (S6) of writing the vertical position value determined in the fifth step in the vertical position control register and using it to display the on-screen display (OSD).

Hereinafter, the operation and operation of the present invention will be described in detail.

If the system is activated, it receives character information data, for example Korean reserved recording data (aka KBPS), reserved recording program, teletext data, or starsite / index flux, The data is decrypted and stored in the memory (S1).

At this time, if an instruction to display the on-screen display (OSD) is input, data to be displayed is read from the memory (S2), and it is determined whether the read information is on-screen display mode related to time (S3).

As a result of the determination, if it is determined that the on-screen display mode is not related to the time, the corresponding on-screen display mode is processed and then terminated.

Next, the start time and end time of each program are calculated, and the calculated value (end time-start time) is calculated and stored in the RAM (S4).

And determines the vertical position of each on-screen display line based on the calculated (end time-start time) value (S5).

The determined vertical position value is written in the vertical position control register of the video RAM for controlling the on-screen display, and is used to display the on-screen display (OSD) and then terminated (S6).

A case of using an external signal in the screen display method operating as described above will be described with reference to FIG.

4, when the end time of the program (the start time of the next program) - the start time of the program (the start time of the program) is within a predetermined time, it is displayed as in the conventional manner without a blank in the vertical line, If the program is over time (for example, over 1 hour), the vertical line will be blank, and for longer programs (for example, if it's a 2-3 hour special) Give it as a blank.

Therefore, it is displayed as in Fig.

5, the date of the input reservation program is stored in the RAM. When the program is displayed, the displayed program is sequentially displayed in comparison with other stored programs.

The start time and the end time of the scheduled recording are calculated, and the calculated time is used to calculate the end time of the program (the start time of the next program) - the start time of the program (the start time of the program) , A blank is displayed on a vertical line as in the conventional case. When the program is over a certain time (for example, over 1 hour), one vertical line is used as a blank, In case (for example 2-3 hours), give the vertical line 2 squares as a blank.

Thus, it is displayed as in Fig.

As shown in FIG. 4 and FIG. 5, a time zone of each program may be displayed as a distance of a screen, and a broadcast length may be displayed in a size or a color by placing a bar on each program line as shown in FIG.

As described above, according to the present invention, when displaying a program to be scheduled to be scheduled to be recorded, the length of the program is adjusted to the length of the screen to give a visual difference to the user so that the user can easily know the length of the program, So that it is suitable for execution without the need.
