Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to program reservation for a television receiver, and displays reservation details on a cathode ray tube screen. (On-screen method % type %) Furthermore, with the spread of TR, the present invention relates to a device that can easily manually enter and confirm complex reservation details.

(Prior Art) Recently, this type of display has been increasing in number, but the operation method/display has become complicated and the function is becoming extremely difficult for users to use.

-For example, if a system uses a cursor to guide you to each location on the screen where you need to input the 0 time or channel number, if there is a lot of information to input, the date 5 time will be displayed.

A series of information such as channel number, on-timer/off-timer, etc. is linked and becomes difficult to check.

■For those that display "Reservation Completed J" in a specific position on the screen when the reservation entry is completed or has already been entered, the font size cannot be made that large due to screen space constraints, so please check << Well, I didn't really like the design either.

(Purpose) The present invention eliminates the above-mentioned drawbacks. For example, in order to collectively input a series of information such as date, time, channel number, on timer/off timer, etc. as one program, one program is made into a long and narrow Indicate with cursor, 1
When you finish inputting a program, the cursor is moved to the next program line, and the background image turns blue while inputting, and when the reservation is completed, it changes to a blue striped pattern for easy viewing. The purpose is to provide a program reservation device with functions.

(Example ) An outline of this system will be explained based on FIG.

Television radio waves from a broadcasting station are input through an antenna, received and processed by a television signal receiving circuit 6, and this processed signal is further supplied to a signal mixing circuit 2 as primary color signals of R, G, and H by a television signal output circuit 5. .

I This signal mixing circuit is supplied with a signal for displaying program reservation contents from the display output control circuit 1. The display position of the display signal is determined by a horizontal display position control device 16 and a vertical display position control device in the controller unit 9.

Variation of the display position, etc. is performed based on various control/data signals from the remote control transmitter. Data of display characters/display figures obtained from the external data RAMIO is transferred to the display data RAM 8 of the decoder circuit 129 via the data interface circuit 11.

From the display data RAM 8, (1) color data signals used in program reservation display are sent to the display output control circuit 1; (2) call signals for characters and background characters used in program reservation display are sent to the character generator 7;・Supply each.

Then, the character is horizontally 1 on shift reno star 4.
The line is entered and the program reservation starts.
l The character is converted into a serial signal and applied to the display output control circuit 1.

Additionally, a tarok generator 14. The melody generator 15 notifies the program reservation timer operation end time etc. by voice.

Embodiments of the present invention will be described below with reference to other drawings.

(Embodiment of background color generator for character display section) Characters and figures on the display can be freely specified and displayed on a dot-by-dot and line-by-line basis using a programmable horizontal display position control device 16 and a vertical display position control device 17. It is possible to do so.

As shown in FIG. 2, the display can display 21 horizontal characters and 6 vertical lines at one time.

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) The dot structure of one character is 12 dots x 12 dots as shown in Fig. 4, and the vertical and horizontal spacing can be freely specified with individual program counters. can.

The display position is designated by a programmable horizontal display position control device 16 and a programmable vertical display position control device 17, and the vertical display position control device 17 is reset by a vertical synchronization pulse and the number of horizontal pulses is counted from that point on. The vertical position is determined by this, and the horizontal position is determined by resetting the horizontal display position control device 16 with the horizontal pulse and turning the tarok pulse. (FIG. 3) The clock pulse has a frequency that is synchronized with and proportional to the pulse representing one horizontal dot of the character structure.

By determining the display position frame as described above, data such as characters to be displayed individually corresponds to each display position.
It includes elements such as "designation of background color of display part, 2. display font size", etc.

The display method of characters and figures is carried out by being sequentially called from the character generator 7 according to the character data, but the data is stored in the external data RAM10.
(random access memory).

The calling system transfers the position data (memory address data) of the horizontal/vertical display position control device 16 and 17 to the decoder circuit 12 via the control data bus.
and data interface circuit J1.

Then, the display data called from the external data RAM10 is sent to the data interface and the chair circuit J1,
The display data RA Ni 8 is transferred from the decoder circuit 12.

This data transfer need not be performed at the same time as character display, but is performed at an appropriate free time before display.

The character characters sequentially outputted by the character call address signal are input to the shift register 4 for one horizontal line, and then are input to the horizontal/vertical display position control device 16.1.
When a display start signal is input from 7, the character signal is converted into a serial signal and input to the display output control circuit 1.

The display output control circuit 1 colors the displayed characters by individually rolling R, G, and B outputs to the character signal according to the background color and character color data using [background color data and character color specification data]. is possible.

The R, G, and B output signals are mixed with a television signal in a signal mixing circuit 2, supplied to a video output circuit 3, and displayed on a cathode ray tube screen.

Figure $5 is a diagram specifically showing the display output control circuit.

This control circuit synthesizes the character character, background color character, character color data, and background color data, and the completed character as shown in FIG. 7 is displayed on the cathode ray tube screen.

FIG. 6 is a table showing color specification register truth values of character color data and background color data.

FIG. 7 shows the relationship between the input and output of the display output control circuit 1.
Figures and ■Electrical signals are described by focusing on one horizontal line between a and b. According to this method, by providing various background color characters, various displays are possible. 1 The system of the present invention is as shown in FIG. 8, (A) is a character whose background color is a single color, (B) is a character whose background pattern is a horizontal line, and (C) is a character whose background color/background pattern is The blank character (D) is a character whose background pattern is a vertical line, and has the above four types of characters.

The above four types of usage are used to distinguish between "timer reservation mode and timer reservation content confirmation" of the timer reservation function, which is a characteristic function of this system.

For example, as shown in Figure 9, when the timer is reserved, the reserved 1
The feature is that the strokes are displayed in one color, and all lines have a horizontal line background when confirming the timer reservation details.

Line break function based on background color> In the background color composition system, the vertical display position control device 17 configures the background color character calling timing. The countdown number data of the programmable counter for background color characters is changed, the display position is changed, and a line break is performed.

In this series of operations, the background color display position change data inputted from the data interface circuit 11 passes through the decoder circuit 12 and enters the control section 9, and the data increases the countdown number of the vertical position program counter by 12 counts at present. , the number of horizontal lines has increased by 12, and the background will be added, so it will actually be shifted down by one line. Therefore, it can be seen as a line break on the display screen. Furthermore, when the count increases by 12, the background moves to the third line.

Next, when the same operation is performed, the series of counts is returned to the original count number displayed on the first line.

In this way, by changing the data of the counter, it is possible to display a line break in the background in synchronization with the line in which the timer reservation is being input.

The above-mentioned line feed system uses a programmable counter, but it can also be implemented by arranging a necessary number of counters with fixed display positions and turning them on and off individually.

<Short-time timer function> When the short-time timer is set to 120 minutes, the first
This will be explained based on Figure 0.

First, the initial value of the Priscella type down counter 20 is set as “
12'' and operates the short-time timer, the 10-minute open reference timer 19 receives the reference pulse from the reference clock generator 14 a predetermined number of times, and supplies a pulse to the counter 20 every 10 minutes. A count operation of -1 is performed by the comparator 18, and a count signal is supplied to the filter unit 9 through the comparator 18. The roll unit 9 receives the count signal, horizontal pulses, and vertical pulses, and projects 12 approximately trapezoidal yellow bars in a wine glass-shaped character in response to the remaining time of the short timer. , the remaining time is displayed by sequentially changing the color to cyan one by one.

To explain this procedure in more detail, in order to display the character, the horizontal display position control circuit 16 and the vertical display position control circuit 1 are stored in the display data RAM 18.
The remaining time display key, character display position address, and color switching data are supplied through the circuit 17.

In response to this, the display data RAM 8 is transferred to the character generator 7 as a character code, and
Color switching data is also transferred to the display output control circuit 1. The character generator 7 sends display character data to a shift register 4, and the register 4 sends a display signal to the display output control circuit 1.

This display output control circuit 1 obtains an RGB signal from the display signal and the color switching data, sends it to a signal mixing circuit 2, and supplies a display signal to display means via a video output circuit 3.

As a result, in response to the remaining time of the short-time timer, for example, if the set time is 20 minutes, the display will initially display a roughly trapezoidal remaining time display character in yellow within the wine glass-shaped character. The winding time is announced in 10 minute increments corresponding to the elapsed time of the timer, and this operation is repeated until the counter reaches zero.

Further, when the counter 20 becomes zero, the control section 9
supplies control data to the melody generator 15;
The melody generator 15 generates audio. This notifies the end of the short timer operation.

<Example of melody generation upon completion of timer operation> When the melody selection means 21 is operated repeatedly, a character code signal and a melody selection signal corresponding to the selected melody are generated.

The character code signal is sent to the external data RAM 10, and the melody selection signal is sent to the melody generator 15. A character code is stored in the external data RAM10.

A particular melody is selected from among the melody generators 15 by a selection signal.

When the timer operation end time comes, the controller 9 detects by the comparator 24 that the contents of the set time register 22 and the reference timer 23 match, outputs a timer end signal, and inputs the star 1 input to the melody generator 15. Supplied.

Then, the melody signal is sent to the audio output circuit, the selected melody is uttered, and the melody stops after a certain period of time has elapsed.

(Effects) As described above, in the present invention, a series of information such as date and time, channel number, on timer/off timer, etc. is set as one program, and the entire one program is indicated with a long and thin cursor. Programs with new functions such as moving the cursor to the line where the next program is located, and (1) changing the background image to a blue color while inputting, and changing it to a blue striped pattern when the reservation is completed for easy viewing. It is a reservation device, and it is easy for the user to operate and check the status.
