Description

Description: TECHNICAL FIELD The present invention relates to program reservation of various electronic devices such as a television receiver and a VTR, and displays reservation contents on a CRT screen. (It is referred to as an on-screen system.) Further, the present invention relates to a device which can easily input and confirm complicated reservation contents with the spread of VTR. (Prior Art) Recently, this type of display has been increasing, but its operation method / display has become complicated, and it is becoming a very difficult function for the user. As an example, in a system in which a cursor or the like is used to guide each location on the screen where a time or a channel number is to be input, when the information to be input increases, the date, time, channel number, ON timer / OFF timer, etc. It is difficult to check a series of information in association with each other. When the reservation input is completed or has already been entered, those that display `` reservation completed '' etc. at a specific position on the screen are difficult to confirm because the character size can not be so large due to the limitation of the screen space, and It was not very desirable in terms of design. (Purpose) The present invention is to eliminate the above-mentioned disadvantages.
In order to input a series of information such as date, time, channel number, on-timer / off-timer, etc. as a single program, the entire program is indicated by a long and thin cursor. It is an object of the present invention to provide a program reservation device having a new function such as a blue stripe pattern at the time of completion of information to make the display easy to see. (Example) Hereinafter, an example in which the present invention is applied to a television receiver will be described. First, a brief description of the present embodiment will be given based on FIG. A television signal from a broadcast station is input from an antenna and received and processed by a television signal receiving circuit 6, and the processed signal is further supplied to a signal mixing circuit 2 as a primary color signal of R, G, and B by a television signal output circuit 5. . A signal for displaying the program reservation content is supplied from the display output control circuit 1 to the signal mixing circuit. The display position of the display signal is determined by the horizontal display position control device 15 and the vertical display position control device 16 in the control section 9. The display position and the like are changed based on various control / data signals from the remote control transmitter. The external data RAM 10 is interposed via the data interface circuit 11.
Is transferred to the decoder circuit 12 and the display data RAM 8. The display data RAM 8 supplies a color data signal used for program reservation display to the display output control circuit 1 and a character and background character call signal used for program reservation display to the character generator 7. . Then, one horizontal character line is input to the shift register 4 and when the program reservation is started, the character character is converted into a serial signal and the display output control circuit 1
Is applied to The above is the outline of the basic system of the present invention. The present invention embodies the background color generator of this system. This will be described in detail below. <Example of Background Color Generating Apparatus for Character Display Unit> Characters and graphics on the display are programmed by a horizontal display position controller 15 and a vertical display position controller 16
Thus, it is possible to freely designate and display each dot and each line. The arrangement on the display which can be displayed at one time can display 21 horizontal characters and 6 vertical lines as shown in FIG. Each line is independent and can be moved to any position on the screen by specifying the display position of the first character. (Fig. 3) As shown in Fig. 4, the dot configuration of one character is 12 dots x 12 dots, and the program counters are also individually set for the vertical and horizontal intervals. it can. The designation of the display position includes a programmable horizontal display position controller 15 and a programmable vertical display position controller.
The vertical position is determined by resetting the vertical display position control device 16 with the vertical synchronization pulse and counting the number of horizontal pulses from that point, the horizontal display position control device 15 is reset by the horizontal pulse and the clock pulse is counted. To determine the horizontal position.
(FIG. 3) The clock pulse is a frequency that is synchronous with a pulse representing one horizontal dot of a character configuration and is in a proportional relationship. By setting the display position frame as described above, data such as characters to be displayed individually correspond to the respective display positions, and “type of display characters, designation of character color, background of display portion” It includes elements such as "color specification, display character size". The method of displaying characters and graphics is performed by sequentially calling the character data from the character generator 7.
(Random access memory). The calling system supplies the position data (memory address data) from the horizontal / vertical display position control devices 15 and 16 to the decoder circuit 12 and the data interface circuit 11 via the control data bus. The display data called from the external data RAM 10 is transferred from the data interface circuit 11 and the decoder circuit 12 to the display data RAM 8. This data transfer does not need to be performed at the same time as the character display, but is performed at an appropriate idle time before the display. As for the character characters sequentially output by the character calling address signal, one horizontal line is input to the shift register 4, and the horizontal / vertical display position control device 15,
When a display start signal is input from 16, the character signal is converted into a serial signal and input to the display output control circuit 1. The display output control circuit 1 can control the R, G, and B outputs of the character signal according to the background color and the character color data according to the "background color data and character color designation data" to color display characters. And The R, G, B output signals are mixed with a television signal in a signal mixing circuit 2 and supplied to a video output circuit 3 to be displayed on a CRT screen. FIG. 5 is a diagram specifically showing a display output control circuit. This control circuit synthesizes the character character, the background color character, the character color data, and the background color data.
The completed character as shown in the figure is projected on the CRT screen. FIG. 6 is a table showing the truth values of the color designation registers of the character color data and the background color data. FIG. 7 is a diagram detailing the relationship between the input and output of the display output control circuit 1, focusing on one horizontal line between a and b for graphics and electric signals. According to this method, various displays can be made by providing various background color characters. As shown in FIG. 8, the system of the present invention comprises (A)
Is a character having a single background color, (B) is a character having a horizontal pattern as a background pattern, (C) is a blank character having no background color / background pattern, and (D) is a vertical character having a background pattern. Characters have four types of characters for convenience. As an example of the use of the four types of characters, for example, the four types of characters are used for distinguishing between “timer reservation mode and timer reservation content confirmation” of the timer reservation function which is a characteristic function of the present system. For example, as shown in FIG. 9, during the timer reservation, all the lines being reserved are displayed in one color, and when confirming the timer reservation contents and when the reservation information input is completed, all the lines are set to a horizontal line background (stripe shape). And so on. The operation at this time is, as shown in FIG. 10, whether or not the reservation information is being input. If the reservation information is being input, one of the specific colors is output as the background image. Depending on whether or not the input is completed, one specific color is striped and output as a background image. (Effect) As described above, according to the present invention, a series of information such as date, time, channel number, on-timer / off-timer is displayed as a program on a screen of a cathode ray tube or the like. In addition to using a specific color such as blue, the background image is displayed in a pattern of the specific color when the reservation information input is completed, so that it is extremely easy and reliably to recognize the input of the reservation information in the reservation mode and the completion of the reservation. Further, since this pattern is the same color as the specific color, the user can use the pattern without feeling discomfort compared to a display such as switching of primary colors such as red, blue, and green. This has the effect of improving comfort during use.
