Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, unique characters, character patterns, colors, and display positions provided by the manufacturer are forced onto the user, ignoring the user's preferences. For example, there may be inconveniences such as users not being able to select if they prefer English text over Japanese text on the display screen, or being unable to change the display color if they do not like it. ing.

The present invention solves the above-mentioned conventional problems, and provides an on-screen display method and device that allows on-screen display information such as characters, character patterns, colors, and display positions to be selected according to the user's preference. The purpose is to

Means for Solving the Problems In order to solve the above problems, the on-screen display method of the present invention uses a screen display setting signal from the user to display on-screen display characters, patterns, etc. stored in advance in a storage unit. The user selects and sets desired on-screen display information from display information such as color and display position, and displays the information.

Further, the on-screen display device of the present invention includes a storage section that stores in advance a plurality of display information such as on-screen display characters, patterns, their colors, and display positions, and a screen display setting signal from the user. The apparatus includes a determination section for selecting and setting on-screen display information desired by the user from a plurality of display information stored in each section, and a display section for displaying the on-screen display information set by the determination section. be.

Operation With the above configuration, display information such as on-screen display characters, patterns, their colors, and display positions, which are stored in multiple numbers in the memory section, can be displayed by screen display setting signals from the user such as remote control signals and key input signals. The determination section selects and sets the desired display information, and the display information desired by the set user is displayed via the display section, making it possible to easily display on-screen display information according to the user's preferences, unlike conventional methods. In addition, the inconvenience of having the manufacturer unilaterally decide on-screen display information and forcing it on the user is eliminated.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an on-screen display device showing an embodiment of the present invention. Components that have the same functions and effects as those of the conventional example are given the same reference numerals and their explanations will be omitted. In FIG. 1, the remote control 11 has an on-screen display selection key in addition to a channel selection key, and when the on-screen display selection key is operated, an on-screen display selection code is transmitted to the television receiver. A nonvolatile memory 12 that stores a plurality of display information such as channel selection information, on-screen display characters, character patterns and colors, and display positions is connected to the V/S microcomputer 13, and the on-screen display information is stored in the V/S microcomputer 13. Input to S microcomputer 13.

The V/S microcomputer 13 includes an O3D circuit 4 for displaying on-screen display information on the screen, a D/A converter circuit 5 for channel selection, and a plurality of data in the nonvolatile memory 12 according to a screen display setting signal from the user. The device includes a determination unit 14 that selects and sets desired on-screen display information desired by the user from the stored on-screen display information.

The operation of the above configuration will be explained below. First, the user operates the on-screen display selection key on the remote control 11 to transmit an on-screen display selection code to the television receiver, and the television receiver receives this code. As a result, a screen display setting signal from the user is input to the V/S microcomputer 13, and based on this screen display setting signal, the V/S microcomputer 13 selects an on-screen display prepared in advance in the non-volatile memory 12. The user selects and sets the desired on-screen display information from the display information, and the SD circuit 4 of the V/S microcomputer 13 displays this on the screen. Note that the screen display setting signal from the user may be a remote control signal from the remote controller 11 or may be a manual key input from a television receiver or the like.

Next, an example of software control of a V/S microcomputer as a microcontroller in a television channel selection system will be described. First, Figure 2 (
Figure 2(b) (C) is displayed by the user making selections and settings on the "display selection menu" screen as shown in a).
The user's desired on-screen display as shown is displayed. In other words, the user can select "Channel number position", "Channel number color", "Message type (Japanese/English)", "Message type (Japanese/English)", "Message type (Japanese/English)", etc. by using the "Display selection menu" screen shown in FIG. 2 (al).
・“Digital to analog converter bar (hereinafter referred to as DAC)
The user can select and set 5 items of ``color of bar'' according to the user's desired preference.

The algorithm in this selection mode is shown in FIG.

In FIG. 3, color flag 1 is the color of the channel number, color flag 2 is the color of the message, and color flag 3 is a software flag indicating the color of the DAC bar. Additionally, the location flag indicates the location of the channel number, and the language flag indicates the type of message (Japanese/English). In the flowchart of FIG. 3, a series of selection settings are performed. Then, once the on-screen display selection settings are made, the on-screen display will be performed accordingly.In Figure 2 (b), the channel number is located at the top left, its color or yellow, and the type of message. In Japanese, the color is green, and the DAC bar color is set to blue. In addition, Figure 2 (C) shows a screen in which the channel number is set to the upper right corner, the color is green, the message type is English and the color is green, and the DAC bar color is set to cyan. ing.

Furthermore, the algorithm for the above display is shown in FIG. Fourth
In the figure, in step 21, the position and color of the channel number are determined using a position flag and a color flag, and in step 22, the channel number is displayed. Furthermore, in step 23, the language flag determines the type of message, Japanese or English, in step 24, the color of the message is determined with color flag 2, and in step 25, the message is displayed on the screen. Further, in step 26, the color of the DAC bar is determined using color flag 3, and in step 27, the DAC bar is displayed.

As described above, the present invention can be easily realized as a channel selection system using such a V/S microcomputer 11. In other words, the key point of the present invention is what kind of software and character generator patterns to control this system should be loaded on the ROM (read only memory). Also,
Nowadays, large-capacity ROMs are available at low prices, so
By performing such control, the amount of ROM for the software can be increased, or by having a rich variety of character generator patterns for on-screen display information, even if the amount of ROM is increased, there is almost no cost increase, and the desired preference of the user can be achieved. It is possible to display an on-screen display according to the

Effects of the Invention As described above, according to the present invention, display information such as characters, patterns, colors, and display positions of on-screen displays was previously determined unilaterally by the manufacturer, or the user's desired preference. It is possible to easily select and display on-screen display information according to the market, and this has a great effect on the market.
