Description

System and method for broadcasting soccer game, and Televsion set for watching soccer game

The present invention relates to a digital broadcast transmission system and method for watching a soccer game, and more particularly, to a broadcast transmission system and method for viewing a soccer stadium as a whole when watching a soccer game on a digital TV. The present invention also relates to a TV receiver that enables viewing of such a soccer game.

In general, when watching a sports game on a relatively large stadium such as soccer or football, it is very difficult for viewers to get a sense of realism when watching the game directly on the stadium. You can watch the game to see the movement of each player, the pattern of the karate, and the flow of the ball to move quickly, so that you can watch the whole game and watch the game, but the TV viewers project on a narrow TV screen as the camera moves. Because you can see only a part of the playing field.

This limitation of the existing TV is due to the limitation of the existing broadcasting system. This is because the existing broadcasting system captures and transmits an image by using a camera that captures an aspect ratio of 3: 4, and the aspect ratio of an existing TV receiver is 3: 4 which is the same as the aspect ratio of the camera.

Therefore, in order to express a stadium soccer game in a conventional broadcasting system, the screen has to be captured from a long distance, and the reduced soccer game screen, which has a significantly lower visibility, provides only the overall form of the stadium, and provides a realistic sense of realism. It is difficult to provide.

Therefore, the conventional broadcasting method adopts a method of broadcasting while alternating the reduced screen captured from a long distance and the enlarged screen captured from a short distance, but it is not enough to provide a living feeling.

Also, because the capture of the fast moving ball and the continuous shooting of the moving ball are entirely dependent on the cameraman's manual operation, if the cameraman inadvertently misses the flow of the ball, the TV viewer will not be able to You will never know.

In addition, due to the shooting range limitation of the camera, the shooting is made around the moving ball or the player, it is difficult to grasp the overall flow of the game, such as the movement of the players other than the player who handles the ball or the pattern of karate, Will be degraded.

In addition, as the existing analog TV system is converted to digital in the future, the desire of a viewer who wants a more realistic screen will further promote the need to improve the screen limitation due to the shooting limits of such a camera.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a broadcast transmission system and method for transmitting a broadcast signal so that the entire soccer stadium can be displayed on one screen.

Still another object of the present invention is to provide a TV receiver capable of providing a realistic screen by displaying the entire soccer stadium.

Prior to this, terms or words used in the present specification and claims should not be construed as being limited to the common or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

According to the present invention, a broadcast signal for viewing an entire soccer stadium includes a plurality of video signals taken by dividing a soccer field into a plurality of areas, and the video signals are displayed on a plurality of display areas in a TV receiver of the present invention. Each scan constitutes an entire screen.

1 is a view schematically showing the configuration of a broadcast transmission system for watching a soccer game according to the present invention. Referring to the drawings, the broadcasting game broadcasting system for watching soccer game of the present invention includes a plurality of (at least two or more) broadcasting cameras 11 and video and audio signals received from the broadcasting camera 11 installed in a soccer stadium. It is composed of a control station 10 for adjusting and sending.

According to the present invention, at least two or more broadcast cameras 11 are divided and provided in the soccer stadium so as to photograph the entire stadium. The number of installations of such a broadcast camera 11 is not limited by the present invention and in the present embodiment, three broadcast cameras 11 are illustrated for convenience.

The broadcast camera 11 is a digital camera, and the video and audio signals photographed through the broadcast camera 11 are output as digital signals. Preferably, the image photographed by the broadcast camera 11 is set so that the brightness, chromaticity, and illuminance thereof match each other, and more preferably, the broadcast cameras 11 are all connected to a main controller (not shown). The above conditions can be controlled to be the same.

The adjusting station 10 includes a screen adjusting unit 20 for adjusting the captured video signal, a synchronizing unit 14 for transmitting and combining the compressed video signal into packets, and transmitting the packet after compressing the compressed video signal. Part 16 is included.

Preferably, the screen adjustment unit 20 is an area adjustment unit 12 for generating only the actual broadcast area signal by removing the superimposed boundary signal from the signal for each area of the stadium as described below, and the brightness and chromaticity of the image for each area. And a color compensation unit 13 for unifying the back.

The synchronization unit 14 synchronizes the digital image signals photographed for each region to combine them into one composite image data packet, and the packet compression unit 15 compresses the composite image data packet into a signal having a size appropriate for transmission. do.

Next, a digital broadcasting transmission method for watching a soccer game using the above system will be described with reference to the flowchart shown in FIG. 2.

The plurality of broadcast cameras 11 installed in the soccer stadium captures the corresponding broadcast area (step S110). At this time, the screen actually photographed by the broadcast camera 11 will be slightly wider than the boundary of the actually allocated broadcast area, so the broadcast areas actually captured by each broadcast camera 11 include areas overlapping each other. .

The video signal for each area photographed by each broadcasting camera 11 is a digital video signal as shown in FIG. 3 (a), which is immediately transmitted to the adjusting station 10, and the screen is adjusted by the screen adjusting unit 20 (step S120).

As described above, the screen adjustment is an area adjustment for removing overlapping portions of each area and a color for unifying brightness, color, etc. of the screen, which may differ due to the specificity and signal transmission of each broadcasting camera 11. It can be divided into adjustments, which are performed in the area adjustment unit 12 and the color adjustment unit 13, respectively.

Specifically, the area adjusting unit 12 extracts only the broadcast screen by removing the overlapping portions near the boundary from the captured screen actually photographed by each broadcast camera 11. For example, as a method of adjusting the area, since the video signal of each area is a digital signal, the screen boundary can be adjusted by searching for the presence of the overlapped signal nodes at the boundary and removing one of the overlapped signal nodes. This area adjustment technique is not limited by the present invention and may be variously applied by those skilled in the art at the time of filing the present invention.

The color adjusting unit 13 adjusts colors such as luminance and chromaticity of the image for each area provided by the area adjusting unit 12 to be unified. Color adjustment is primarily made to some extent in the broadcast camera 11, but the color adjustment unit 13 makes finer color adjustments, so that each image is displayed on an individual display area of the TV receiver 20 as described below. This is to prevent the difference in image quality even if it is displayed.

As described above, the image signal for each region (13a of FIG. 3) in which the screen region adjustment and the color adjustment are completed are all transmitted to the synchronization unit 14 and combined into one, thereby packetizing the composite image signal (step S130).

For example, the synchronizer 14 adds the head signal (H in FIG. 3), which is a field separator, to the head of the image signal data for each region, and combines each region signal to which the head signal H is added. The head unit adds a synchronous control signal S to generate a composite video signal packet composed of a plurality of area-specific video signals.

In the present invention, the video signal for each region may be data corresponding to one scan line or data corresponding to one frame in the display area of a TV receiver described later according to the present invention. In this case, the synchronization control signal S plays a role of synchronizing so that an image of each region is displayed as a matched image when scanned in the display region of the TV receiver.

Subsequently, the composite video signal as described above is compressed to a size suitable for transmission by the packet compression unit 15, thereby reducing the capacity of the transmitted broadcast signal and at the same time losing data due to inflow and interference of external signals during transmission or To prevent fouling (step S140).

The compressed composite video signal packet is transmitted through the transmitter 16 as described above. The transmission unit modulates the composite video signal and loads it on a carrier to be transmitted through the transmission tower 17 or the like, which is received by the antenna 21a and input to the TV receiver 100. In the case of satellite broadcasting, it is received by the satellite antenna 21b via the satellite 18 and then transmitted to the TV receiver 100.

Although not described in the present embodiment, it should be understood that the audio signal is also packetized and transmitted together with the composite video signal. The audio signal may be encoded by a microphone (not shown) attached to a digital broadcasting camera or a separate microphone and output as a digital signal. In this case, the audio signal may be processed to be synchronized with the video signal to form an audio signal field as part of a composite video signal. can do. However, since the processing method of the voice signal is not a characteristic configuration of the present invention, the voice processing method in the existing broadcasting system can be applied. In this case, the voice may be frequency-modulated as before and may be transmitted separately from the video signal. Hereinafter, in the present specification, a voice signal is also processed into a digital signal and described as packetizing in the same manner as an image, but the present invention should not be construed as being limited thereto.

Then, a TV receiver for watching soccer matches according to another embodiment of the present invention will be described. As described above, the TV receiver for watching a soccer game receives a composite video signal in which a plurality of video signals for each area are combined, and displays the composite video signal for each display area of the monitor so that the entire soccer stadium can be viewed at a glance.

4 is a diagram showing the configuration of such a soccer game watching TV receiver. Referring to the drawings, the TV receiver 100 of the present invention includes a tuner unit 30 for selecting a broadcast signal corresponding to a desired broadcast channel, a detector 35 for extracting a composite video signal packet from the received broadcast signal, A packet restoring unit 40 for restoring the extracted composite video signal packet, an image processing unit 50 for processing the image signal obtained as a result of the restoration, and a screen reproducing unit 80 for reproducing and outputting the processed final image to the display unit; Include.

The TV receiver 100 of the present invention is connected to receiving means for receiving a desired digital broadcast signal, which is not only a terrestrial wave and satellite signal which is a conventional broadcast signal transmission method, but also a wired network such as an internet network and a cable. A broadcast signal provided in various forms, such as a signal transmitted through 21c, may be received. For example, terrestrial waves are received using a general TV antenna 21a, signals transmitted from satellites are received using a satellite antenna 21b, and signals transmitted through a wired network 21c are network connection devices (not shown). Can be received.

The tuner 30 selects a broadcast signal of a desired channel from the broadcast signals received by the receiver, and the tuner 30 amplifies the received broadcast signal having a small size.

The detector 35 removes the carrier from the modulated broadcast signal and separates the original composite video signal. The detection unit of a conventional TV receiver separates a single video signal from a carrier wave, but in the present invention, separates a packet signal in which a video signal and a synchronization signal (and a voice signal, if necessary) for each region are combined.

The packet restorer 40 decompresses the received composite video signal packet and restores the received composite video signal packet to the video signal for each region. At this time, the synchronization control signal S is also restored.

The image processor 50 processes reconstructed image signals of respective regions, extracts and amplifies signals necessary for image reproduction such as horizontal and vertical signals, luminance signals, color signals, and color burst signals, and outputs them. According to the present invention, the image processing unit 50 includes a plurality of processing units 51, 52, and 53 for processing image signals of respective regions.

The screen reproducing unit 80 is a screen driving device that displays a screen on the display unit 90 such as a monitor according to signal information for each region obtained from the image processing unit 50. Here, the display unit 90 is preferably a flat display element such as an LCD or a PDP, and more preferably, the ratio of the horizontal length to the vertical length is, for example, about 1: 6.

According to the present invention, the display unit 90 has a plurality of display regions 91, 92 and 93, which are preferably driven independently and correspond to the image signals of the respective regions. The display areas 91, 92, and 93 are preferably combined such that there are no discontinuities at the boundary or as few as possible. The reason is that even when the luminance and chromaticity of each screen area 71 exactly match, If present, the sense of unity of the screen is impaired, and the effect of watching a soccer game intended by the present invention is reduced.

Hereinafter, the operation of the TV receiver according to the present invention having the above configuration will be described with reference to FIG. 5.

First, the broadcast signal transmitted by the broadcast transmitting system of the above-described embodiment reaches a receiving means such as the antenna 21a, and the user selects a broadcast signal of a desired channel by operating the tuner unit 30 (step S210). As described above, the broadcast signal is a signal in which a composite video signal (see 14a of FIG. 3) is modulated by a carrier wave, and the composite video signal includes a packet signal in which a plurality of region-specific video signals are combined.

The broadcast signal is amplified and transmitted to the detector 35 while passing through the tuner 30. The detector 35 removes the carrier from the modulated broadcast signal, extracts the original composite video signal packet, and transmits the original composite video signal packet to the packet restorer 40 (step S220).

Subsequently, when the extracted composite video signal packet is applied to the packet restorer 40, the packet restorer 40 decompresses the compressed video signal, and then separates the plurality of region-specific video signals and the synchronization control signal S therefrom. (Step S230). The region-specific image signals may be divided according to their field head signals H. At this time, if the voice packet is included in the signal packet, this is also separated and extracted.

Then, each of the reconstructed signals is transmitted to a corresponding processor. The image signals for each area are sent to an image processor 50 having respective processors 51, 52, and 53 corresponding thereto, and the synchronous control signal ( S) is sent to the synchronous control unit 70. The synchronization control unit 70 synchronizes a plurality of area images reproduced by the screen reproducing unit 80, which will be described later, by using the synchronization control signal at the same time.

The image processor 50 processes image signals of respective regions, extracts signals necessary for image reproduction such as horizontal and vertical signals, luminance signals, color signals, and color burst signals, and outputs them to the screen reproducing unit 80.

On the other hand, the voice signal extracted from the packet restorer 40 is transmitted to the voice processor 60 is output to the speaker 61 through the digital / analog conversion. Preferably, this audio output is set to be synchronized with screen reproduction as described later.

The screen reproducing unit 80 is used in each of the reproducing units 81, 82 and 83 in each display area 91, 92 and 93 of the display unit 90 according to the image signal received from the image processing unit 50. Images are reproduced and output for each area. The screen reproducing unit 80 displays a color image according to a matrix (not shown) and a color signal for determining a scanning area (eg, an on / off driving point in the case of an LCD) according to pixels of the display areas 91, 92, and 93. It includes a color reproduction unit (not shown) to reproduce.

According to the present invention, a plurality of region-specific image signals are scanned in respective display regions corresponding thereto. That is, the first area video signal is scanned in the first display area 91, the second area video signal in the second display area 91, and the third area video signal is scanned in the third display area 91. Preferably, the first area image signal is scanned from the first scan point 91a of the first display area 91, and the second area image signal is scanned from the second scan point 92a of the first display area 92. The third region image signal is scanned from the third scan point 93a of the third display region 91.

At this time, scanning at the scanning points is synchronized and made simultaneously, which is made possible by the synchronization control unit 70 controlling the scanning according to the synchronization control signal. Thus, the viewer can display three display areas 91, 92, and 93. At the same time, the screen being played at the same time feels like a single image, so that the entire soccer stadium can be viewed.

Although the present invention has been described with reference to specific embodiments and drawings, the present invention is not limited thereto and the technical spirit of the present invention and claims to be described below by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents.
