The present invention relates to a method and apparatus for displaying an elapsed broadcast time of a broadcast program on a television screen when a viewer desires it.

1 is a block diagram of a conventional television circuit generally used, which is a tuner 2 for tuning a broadcast signal received from an antenna 1 and an intermediate frequency for amplifying an output signal of the tuner 2; An amplifying section 3, a detector 4 for receiving and outputting an output signal thereof, an image processor 5 connected to a detector 4 and an OSD processing apparatus 8 and controlled by a microcomputer 7; And an image amplifier 6 for amplifying and outputting the output signal from the apparatus 5.

Referring to the operation of this circuit, first, the signal received by the antenna 1 is input to the tuner 2, and the connected data lines and clock lines of the tuner 2 are controlled by the microcomputer 7. The output signal of the tuner 2 is input to the image detector 4 via the intermediate frequency amplifier 3, and the output of the detector 4 is input to the image processing apparatus 5. The image processing apparatus 5 is controlled by the connected microcomputer 7. The output signal from the image processing apparatus 5 is passed through the image amplifier 6 so that the R, G, and B image signals are displayed on the television CRT.

When the viewer inputs a channel change, a volume control, or a color control of a television through a remote controller, the microcomputer 7 sends data and a clock signal to the OSD processing unit 8 to display such a change or adjustment display on the television screen.

The conventional OSD display device of this type has a function of displaying information on volume control, image control, or channel change on the screen. However, when a user watches a program such as a feature film or a soccer game broadcast, the viewer operates the remote control. This program was uncomfortable because I did not know the elapsed broadcast time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for a viewer to operate a remote controller to display an elapsed time of a corresponding program on a screen using an OSD device of a television.

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

2 is a block diagram of a television circuit implementing the method of the present invention. The dotted line portion in the drawings is a portion newly added in the present invention.

Description of the overlapping part of FIG. 1 is abbreviate | omitted, and the same code | symbol is attached | subjected to the same code | symbol of FIG. 1 and FIG.

As shown in FIG. 2, the novel part of the present invention includes a remote controller 9 for adjusting a television operating state, a preamplifier 10 for receiving and amplifying a signal of the remote controller 9, and a preamplifier 10. As shown in FIG. Is a timer generator 11 under control of the microcomputer 7 and a memory 12 storing screen display information.

When the TV signal is input to the tuner 2 through the antenna 1, the tuner 2 sends a data signal and a clock signal to the microcomputer 7.

The signal output under the control of the microcomputer 7 is input to the intermediate frequency amplifier 3, amplified, and then enters the detector 4.

The detection output signal from the detector 4 is input to the image processing apparatus 5, and the necessary image information controls the image processing apparatus 5 through the data and the clock signal with the information stored in the microcomputer 7. . The signal from the image processing apparatus 5 is amplified by a signal required by the image amplifier 6 to output an image signal.

When a desired one is selected for TV operation and input by the remote controller 9, it is recognized by the microcomputer 7 via the preamplifier 10. The signal recognized by the microcomputer 7 recognizes the information initially designated by the OSD processing apparatus 8 and is displayed at the designated screen position.

When a specific key of the remote controller 9 is input to display the broadcast elapsed time, the preamplifier 10 is amplified by the preamplifier 10 to recognize the signal and sends a signal to the timer generator 11, and the information necessary for the timer. For example, when information is obtained from a memory 12 that stores character size and shape, display position, minute data, time data, and display form information, a timer is operated to send a signal to the OSD processing apparatus 8, and the existing OSD is displayed. By using the display method, the conveyance elapsed time display to be displayed at the desired position on the TV screen is performed.

Next, an OSD display device 8 for displaying a program broadcast elapsed time will be described.

In the method of forming characters for OSD display on the screen, the conventional channel display is the same as other OSD characters, but when the OSD character is displayed for a long time, if the character is too large, it may interfere with viewing, so it is appropriately sized.

4 shows an embodiment of a character to be displayed on the screen.

In this embodiment, the font (FONT) to be formed is composed of 8 x 10 dots, and one character occupies one byte (8 bits), so that the memory 12 includes (00000100), (00011000), (00000100)... Save it in the way.

As shown in FIG. 5, the positions of displaying the characters stored on the TV screen are varied, but as shown in FIG. 5, the TV screen is divided into 8 horizontal lines and 6 vertical lines.

Fig. 5a consists of a line of 1 line and a line of 1, b line of 1 line, 6 lines, c line of 8 lines, 1 line, and d of 8 lines, 6 lines The character position information on the TV screen is stored in the screen display position of the memory 12.

The format of displaying the elapsed time of the program on the TV screen is determined in the form of □□: □□ as shown in Fig. 12:34 of Fig. 5 and stored in the designated place of the screen display form of the memory 12.

The method of implementing the apparatus of the present invention first assumes that the screen display form is XY: WZ, and the data relating to Z, which is one digit of the number of digits in the minute data storage location of the memory 12, is represented by starting point data = 0, end point data = It is set at 10, and the data regarding W which is the tenth digit is set to start point data = 0 and end point data = 6.

In the time data storage location of the memory 12, the start point data of Y, which is one digit of time, is set as 0 and the end point data = 10, and the start point data of X, which is the ten digits of time, is set as 0 and the end point data = 10, respectively. Put it.

3 is a flowchart illustrating an operation in which the elapsed program time is displayed on the TV screen. When the execution command is input to the preamplifier 10 of the television via the remote controller a (S1), the microcomputer 7 recognizes the command and sends a command signal to the timer generator 11.

Recognizing this signal, the timer generator 11 initializes the time data of the minute data of the memory 11 to the viewpoint data (S2), and operates the timer generator 11 (S3).

At the same time, data and a clock signal are sent to the OSD processing unit 8 to display the current data at a predetermined position on the TV screen (S4). At this time, the counter is continuously performed (S6) to recognize the Z value and continue to display on the screen. If the Z value is greater than or equal to 10, which is the end point data (S6), and if the value is greater than or equal to (S6), the W value representing 10 digits of the minute data is increased by one (S7), and if the W value is less than 6 (S8). ), And repeat the current data display. If the W value is greater than or equal to 6, the Y value representing one digit of the time data is increased by 1 (S9), and the above process is repeated than when the Y value is less than 10.

If the value of Y is greater than or equal to 10 (S10), the X value of 10 digits of the time data is increased by 1 (S11), and the above process is repeated until the X value is less than 10. If the X value is greater than or equal to 10, the time becomes three digits, so only the time is performed up to this point, and the minute and time data are initialized to 0 to be repeated.

If you want to cancel the broadcast elapsed time while the operation is being performed, input through the remote control unit 9, the microcomputer 7 recognizes and sends a signal to the timer generator 11, the timer generator 11 is the OSD processing device (8) and the clock and data signals are sent to stop the OSD display immediately, and the minute and time data in the memory 12 are initialized to time data = 0 and the operation is stopped (S13-S15).

As described above, the television of the present invention can display the time on the TV screen by a simple operation of the remote controller 9 when the elapsed time of the specific broadcast program is to be known, and can also function as a stopwatch, which is very convenient.
