Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of operating a television signal during broadcasting, and more particularly to a television program during broadcasting, not from a broadcasting station such as a studio or a relay station where broadcasting programs are produced and broadcast. From the place where the program can be monitored, for example, while monitoring the program being sent, by sending a signal indicating the position on the screen by a specialist or general viewer about the program content to the broadcasting site using a personal computer, It enables real-time operation of various television signals by automatically superimposing an arrow or a finger mark on the indicated position of the television signal being broadcast and broadcasting.

[0002]

2. Description of the Related Art In television programs, program contents are often easy to understand when a position pointing mark such as an arrow pointing to a part of the screen or a finger is displayed on the screen for the sake of production. Has been put into practice.

As a practical method, for example, in a studio or a relay site, a person uses a pointing stick to explain a drawing and takes it with a television camera, or an arrow is electronically used by using a personal computer or the like. In a device that is designed to generate, a method has been adopted in which the arrow of the generated device is moved with a mouse or the like, and the image of the generated arrow is electronically superimposed on a television screen and displayed.

[0004]

However, all of these methods are possible only when the person who operates the position pointing mark is at the broadcasting site (studio, relay site, etc.). Therefore, it is unavoidable that an outsider, etc. cannot point to any point on the television screen that is being broadcast from a place away from the place where it is being broadcast. There was no way.

An object of the present invention is to provide a television signal being broadcast, at a point far away from the broadcasting site, not from a studio or a relay site broadcasting the television signal. It is an object of the present invention to provide a method of operating a television signal on the air, which allows a person watching a program to display a position indication mark indicating an arbitrary point on the screen in real time in a superimposed manner on the television signal on the air. .

[0006]

In order to achieve the above object, the present invention provides a position on a television screen using a position input means at a place other than a broadcasting site where a television received image during broadcasting can be monitored. Is transmitted to the broadcasting site via a wired or wireless communication line, and the transmitted data signal is received at the broadcasting site, and the received data signal is It is characterized in that a video operation signal related to the position on the television screen is generated, and the television signal being broadcast is operated by the generated video operation signal.

[0007]

According to the present invention, the position indicating mark can be displayed at a specified position on the television screen during broadcasting in real time. However, the present invention is not limited to this, and the specified position is continuously shifted. , Or draw a line on the TV screen by specifying the start and end points, draw an arbitrary line drawing, and select which of the several selection targets displayed on the TV screen. It is also possible to display, etc. Therefore, various applications of the present invention are conceivable. For example, regarding a professional program, ask a specialist in the way to explain it, or in a quiz program, a viewer You will be able to easily perform productions such as having people participate in.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a block diagram conceptually showing a method of operating a television signal during broadcasting according to the present invention. Here, a case will be described in which a professional television program is being broadcast, and a commentator puts an arrow in place of a pointer on the television screen being broadcast at home to increase the degree of understanding of the viewer.

In the commentator's house 1, in addition to the television receiver 2, a notebook type personal computer (including special software) 3 with a mouse 4 is installed in order to achieve the present invention. This personal computer 3 is connected to a telephone line 7 through a modem (modulator / demodulator) 5 and dialed to make a notebook personal computer 3.
Is transmitted to the broadcasting station 8.

On the other hand, in the broadcasting station 8 as a broadcasting site, a personal computer 9, an NTSC converter 10 and a super imposer 11 are provided as permanent equipment especially for the present invention, and other notes transmitted from the commentator's house 1 A modem 6 for receiving and demodulating the output of the personal computer 3 and a conventional image adjusting device 12 are installed. In the case where the present invention is not applied, the output of the video adjusting device 12 is directly broadcast to the general audience by the broadcast device 13 installed in the broadcast station.

Next, the operation of the present invention will be described. It is assumed that the commentator views the target program on the television receiver 2 and answers the question from the announcer, for example, and inserts an arrow at the position shown in the figure on the television screen. In this case, the commentator first uses the notebook computer 3 set in the same frame as the screen of the television screen to move the mouse 4 so that characters and symbols (including arrows) can be displayed at desired positions on the screen. The position setting button of the mouse 4 is pressed when the arrow is at the position shown in the figure. As a result, a data signal (coordinate signal) representing the position is output from the notebook computer 3 and the telephone line 7 to the broadcasting station 8 is connected.
Is already connected, the coordinate signal is input to the personal computer 9 of the broadcasting station 8 via the modem 5, the telephone line 7 and the modem 6.

In the personal computer 9, an arrow is displayed on the screen of the personal computer 9 according to the input coordinate signal. The arrow created by this personal computer 9 is the NTSC converter 10
Is converted into an NTSC television signal by the superimposer 11 and superposed by the superimposer 11 on the video output from the video adjustment device 12 and broadcast from the broadcasting device 13. As described above, the commentator can superimpose, in real time, a position indication mark such as an arrow at any desired position on the television screen while monitoring the broadcast television program.

Although the method of operating the television signal during broadcasting according to the present invention has been described above in the case where the position indicating mark such as an arrow is superimposed on the television screen during broadcasting, the present invention calls from a place other than the broadcasting site. Since the coordinate signal consisting of a digital signal is transmitted via the line, not the position indication mark (video signal) itself,
Based on this coordinate signal, various operations can be performed on the video signal displayed at the coordinate position on the television screen without being limited to superimposing the arrow or the like on the desired position.

For example, a circuit configuration such as drawing a line on a television screen during broadcasting, drawing an arbitrary line drawing, or selecting one of several selection objects displayed on the screen at the broadcasting site. Will also be possible. In order to select a desired function from among these multiple functions, first display the function menu on the screen of the laptop computer and then select a specific menu from the menu to broadcast the corresponding menu data. It is transmitted to the site, and at the broadcast site, the necessary circuit configuration is automatically taken.

Now, it is assumed that the menu for drawing a line drawing is selected by the above-mentioned method and the circuit configuration for that is taken at the broadcasting site. At this stage, if the commentator moves the mouse while pressing the position setting button of the mouse, the coordinate data representing the locus of movement is sequentially taken out from the notebook computer and transmitted to the broadcasting site. The personal computer at the broadcasting site operates, for example, by drawing a straight line between two points of the coordinate data that are sequentially transmitted. By performing this continuously, a line drawing can be drawn. In this case, if the transmission frequency of data per unit length is high, it is possible to draw a curve approximately, and it is also possible to connect two points with a cubic spline curve regardless of the transmission frequency.

The above-mentioned plurality of functions include a function of erasing a drawn line drawing. To delete the drawn line drawing, for example, it is assumed that the space key of the notebook computer is pressed between the commentator side and the broadcasting site. When the commentator presses the space key, the information is transmitted to the PC at the broadcasting site, and the PC is configured to erase the screen.

On the commentator side, the mouse for specifying the position of the television screen can be replaced with various position input means such as a touch panel. In addition, a television screen (single color may be used) on the laptop computer screen.
The usability is further improved by configuring so that can be displayed simultaneously.

[0018]

According to the present invention, if the commentator is in a state where he / she can watch the television program being broadcast even if he / she is not at the broadcasting site, for example, a laptop computer (with a mouse and special software) ), A modem and a telephone line are prepared so that any desired position on the television screen during broadcasting can be pointed by the position indicating mark. In addition to displaying the position indication mark, an image such as drawing a line on the screen, drawing an arbitrary line drawing, or displaying which one is selected from several selection targets displayed on the television screen is displayed. It is also possible to perform the operation in real time.

Further, according to the present invention, since the signal transmitted from the place which is not the broadcasting site to the broadcasting site is not the video signal but the coordinate signal, a telephone line which can be used anywhere without a special transmission line may be used. This facilitates the practice of the invention, which is a great practical advantage.
