System for broadcasting a selected motion pictures in multi motion pictures of TV}

The present invention relates to a television broadcasting system. More specifically, when a video screen signal is transmitted from a broadcasting station using a plurality of cameras, a viewer can select a screen that he or she wants to watch from among different screens that capture the same situation from different angles. The present invention relates to a television broadcasting system capable of selecting a screen.

Due to the development of modern television technology, digital televisions have been developed and sold from the early black and white to color receivers. Such digital televisions have a function to service various broadcasts through various channels, thus giving viewers various channel choices, but they have fundamentally limited broadcast contents.

In other words, in the case of relaying a sports game such as basketball, a plurality of cameras are arranged up, down, left, and right around the floor where players play and relay or record the play situation of players in various angles in real time. However, the signal transmitted to the viewer is relayed to the television receiver only one screen selected by the PD in charge from among the screens of the cameras captured at various angles. As a result, the viewers were dissatisfied because they did not have the choice of the screen of the situation they wanted.

In addition, since the broadcasting station selects and transmits only one screen from various screens, the intention to deliver it to the viewer is not properly delivered, and there is a problem that a large number of technical personnel must be input for screen selection.

Also, in the 21st century, the tendency of viewers to be more free from time and space, and to change to the leading tendency to choose for themselves rather than given, it is necessary to change the broadcasting form of TV in this era. It is becoming.

The present invention has been made to solve the above problems, an object of the present invention is to transmit a video screen signal from a broadcasting station using a plurality of cameras, viewers to watch from different screens to grasp the same situation from different angles The present invention provides a television broadcasting system that can give a viewer a choice of screen by selecting a desired screen.

Hereinafter, a television broadcasting system capable of selecting a screen according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an embodiment of a television broadcasting system capable of screen selection according to the present invention.

As shown, at least two or more cameras 10, 12, 14, 16 and 18 and image signals output from the cameras 10, 12, 14, 16 and 18 are processed for output. A signal processor 20, a signal modulator 22 for modulating a signal output from the signal processor 20 into a wireless signal, and a signal output from the signal modulator 22 propagates as a wireless signal And an antenna 24 for receiving the signals, and the televisions 30 and 32 that receive the signals are in a reception state as in the prior art.

The first to fifth cameras (10, 12, 14, 16, 18) is composed of at least two or more cameras, essentially arranged with the cameras to hold the screen from various angles up, down, left and right for conventional broadcasts May be similar. Of course, the number of cameras can arbitrarily set at least two or more cameras. The first to fifth cameras 10, 12, 14, 16, and 18 respectively output a signal by grabbing a drama, a talk show, a game relay, etc. in the arranged state.

Such cameras are preferably fixed at all times unlike conventional cameras. By doing this, viewers can concentrate on watching only their favorite scenes. Or in the case of sports relay can be adjusted to move the camera according to the movement of a specific athlete.

The output signal is input to the signal processing device 20. The signal processing apparatus 20 processes and outputs signals input from respective cameras. An important operation of the signal processing device 20 is not to output only one signal from each signal of the cameras input, but to process and output all signals input from the cameras.

In other words, the signals input from the first to fifth cameras 10, 12, 14, 16, and 18 are normally synthesized and modulated and output as in the conventional method, so that audio and video signals are normally output from the television set. Can be a signal.

The video and audio signals normally output from the signal processing device 20 are modulated into radio signals by the signal modulation device 22, respectively. This modulation process goes through essentially the same process as the conventional TV broadcaster. The difference between the present invention and the conventional broadcasting method is that in the conventional broadcasting station, only one camera signal selected by the PD is output from the signals input through the various cameras. The signals are output as different channel frequency signals.

For example, if the channel of the first camera 10 is channel 3, the channel of the second camera 12 is channel 4, the channel of the third camera 14 is channel 5, and the channel of the fourth camera 16 is Channels 6 and 5 of the fifth camera 18 are set to channel 7. This is difficult at present due to the limitation of the number of available channels, but digital broadcasting is popularized, the number of available channels is increased, and also by using digital signal processing technology, time division and frequency division technology in one frequency band. Since a plurality of broadcast signals can be inserted, the conventional technology can be easily solved. Inserting a plurality of broadcast signals into one channel using channels separated from each other or by a digital signal processing method is implemented by the signal processing apparatus 20.

Each of the camera image signals processed by the signal processing device 20 is a radio signal having a different channel frequency through the signal modulator 22, or a radio signal state all contained in one channel. Propagated through the air. It is received in each television similar to conventional over-the-air broadcasting.

Each of the televisions 30 and 32 can select a specific screen by changing a channel or changing a frequency in one channel when video and audio signals are input through the antennas 24a and 24b.

Alternatively, instead of setting the channels to different channels, a plurality of camera signals may be simultaneously synthesized and transmitted using time division or frequency division techniques. In this case, a tuner specially designed to tune a specific signal among the signals modulated by the television receiver is required.

4 is a diagram for one embodiment in which a menu for selecting a camera signal is displayed at the bottom of a screen while watching TV.

As shown, with the channel fixed, menus such as "1. Front", "2. Side", "3. Far Front", "4. Rear", and the like are output. Of course, it is obvious that the menu can be appropriately changed according to the position of the camera or the broadcasting condition. In addition, the menu selection may be a signal indicating another channel change, which is changed according to the type of the signal processing apparatus 20. The numbers displayed in the menu are set to correspond to the cameras, respectively.

When the viewer changes the number displayed on the screen (channel change or screen signal change), this is to select the signal of the camera, and if the screen shown in Fig. 4 is the front view, select "2. Side" In this case, the side rather than the front of the person is displayed on the screen. Also, if "4. rear" is displayed, the back of the person is visible. Such screen selection is advantageous in that the viewer can freely select the screen he or she wants to view. This also has the advantage that when the viewer wants to edit the screen, he or she can arbitrarily select the desired content, so that the content can be edited more effectively by manipulating the editing state.

Looking at this from an educational point of view, when watching the educational content for language learning, recording the three-dimensional state holding the screen from various angles rather than the flat state as in the prior art increases the effect of memorization and role-playing, resulting in an educational effect. There is a rising advantage. This process is shown in the flowchart of FIG.

Fig. 2 shows a system that can be applied to the case of cable television as another embodiment of the present invention.

As shown, at least two cameras 10, 12, 14, 16 and 18 for photographing, and a signal processing device 20 for modulating a signal input from the cameras 10, 12, 14, 16 and 18. ), A signal relay device 26 for relaying at least one or more camera output signals output from the signal processing device 20, and each camera 10 from a signal relayed through the signal relay device 26. And a signal tuning device 28 for selecting and outputting one of signals 12, 14, 16, and 18. The signal relay device 26 and the signal channel device 28 are connected by a cable.

This is applied to a conventional cable TV, the signal processing device 20 processes and outputs a signal input from each camera. An important operation of the signal processing device 20 is not only to output one signal from each signal of the input cameras, but to signal-process and output all of them. In other words, since the signals input from the first to fifth cameras 10, 12, 14, 16, and 18 are all processed and output as in the conventional method, the receiver is a signal capable of normally outputting audio and video signals. .

The signal output from the signal processing device 20 is transmitted through a cable through the signal relay device 26. The signal relay 26 may, for example, include functions for amplifying the magnitude of a signal transmitted through a cable. The signal relay device 26 transmits a signal to the subscriber television. The signal transmitted through the signal relay 26 includes all video signals captured by the cameras 10, 12, 14, 16, and 18.

The transmission method of the camera video signal can be simultaneously transmitted by allocating the bandwidth of each camera video signal to different frequency bands, which can be achieved by conventional digital technology or analog technology.

As described above, the camera video signal transmitted by the signal relay device 26 to each subscriber television via a cable is input to the signal tuning device 28. The signal relay device 26 is a device for selecting a specific video signal from a plurality of video signals. The television viewer can select a screen to be viewed by pressing a specific number on the menu screen displayed on the screens of the televisions 30 and 32 using the remote controller.

This will be described again with reference to FIG. 4. In a state where the channel is fixed, menus such as “1. front”, “2. side”, “3. remote front”, “4. rear”, and the like are output. Of course, it is obvious that the menu can be appropriately changed according to the position of the camera or the broadcasting condition.

As described above, the user selects the menu and presses the corresponding number while the menu is displayed at the bottom of the screen. The control unit (not shown) of the television is connected to the control unit of the signal relay device 26 so that the signal relay device 26 selects an output of a specific video signal. Therefore, the television 30, 32 outputs the screen selected by the viewer. With the VCRs connected to the televisions 30 and 32, the viewer can select and record a screen captured at a specific position, so that the contents can be recorded according to his or her taste.

In addition, even when the language education broadcast (a broadcast that outputs a plurality of camera image signals simultaneously) is output from a TV, the education effect can be increased because the video signal can be recorded at a desired position.

As described above, according to the present invention, when a video screen signal is transmitted from a broadcasting station using a plurality of cameras, the viewer has an advantage of selecting a screen to be viewed from different screens having the same situation at various angles.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
