BACKGROUND OF THE INVENTION
The present invention relates to a display system for competition vote information installed in public stadiums such as horse races, and more particularly to a display screen control system of an information display device that provides competition voting information to visitors by text broadcasting means and video broadcasting means.
[0002]
[Prior art]
FIG. 3 is a schematic system configuration diagram of a display screen control system of an information display device according to the prior art. For public stadiums such as racetracks, bicycle racetracks, and racetracks, it is a fan service that participates in voting. Many types of information display terminal devices are installed. The center device 1 introduces the running horses by video devices 11 such as a plurality of cameras, the introduction of the competitors, the actual situation information by the video means such as the actual situation of the competition, the running horses created by the teletext production section 2, The game voting information such as the participating players and odds is displayed and output on the display device 6 connected to the information display terminal device 5.
The operation will be described in detail. Video signals picked up by a large number of cameras 11a to 11n and the like are modulated into carrier signals having different carrier frequencies by a plurality of MODs (television signal modulators), and mixed and output by a mixer & transmission unit. This form is equivalent to a television broadcast channel forming a transmission channel for each carrier frequency. On the other hand, the teletext program production unit 2 creates a teletext voting information program in the teletext format based on the competition data received via the in-field communication line 7 in the stadium. The competition voting information program is superimposed on the video signal selected by the selecting unit 13 by the superimposing unit 14 and sent out as a carrier signal of a predetermined channel.
[0003]
A plurality of channels of carrier signals are sent to a large number of information display terminal devices 5 via a broadcast communication line 4 such as CATV (cable television).
The reception unit 51 of the information display terminal device 5 selectively receives the reception channel designated by the channel selection unit 56. The received signal is demodulated into a video signal and a teletext signal by the demodulator 52 and output to the display device 6.

[0016]
The detailed operation of the teletext program production unit 2 will be described along the information flow.
Various competition voting information necessary for the production of the teletext program is communicated and input from the competition management system (not shown) installed in the center via the local communication line 7, and a competition management data file (not shown). Is stored and input as competition management data. At the same time, the program control unit 30 instructs a competition voting information data creation unit (not shown) to create competition voting information data for teletext, and stores the competition voting information data in the teletext data file 21.

Designated color display control mode for controlling the display output of the display device so that it becomes the designated color screen during display preparation, etc.
A sleep display control mode for controlling the display output of the display device to be a sleep state screen is used.
[0018]
Further, the center device is provided with a time display generating unit that generates an elapsed time image of a game or the like not shown in the figure, and the elapsed time image generated by the time display generating unit is superimposed on the video signal by the superimposing unit 14 and output. . By inserting the elapsed time into the live broadcast screen of the competition, it is possible to display the elapsed time in real time without the time delay like the teletext means.
[0019]
A flow of signals in the display terminal device 5 will be described.
The receiver 51 selectively receives a plurality of carrier signals from the broadcast communication line 4, and the demodulator 52 separates and demodulates the video signal Video and the teletext signal TXT. The teletext signal is decoded by the teletext decoder 53 and temporarily stored in the received data memory 54. In the teletext system, a large number of teletext programs are sent cyclically, so the data update is relatively slow, and it takes time to display the data when it is received whenever necessary. Not suitable for. For this reason, the reception data of all programs are temporarily stored and input into the reception data memory 54 and read out locally from the reception data memory 54 as necessary.
The teletext program is selectively read from the reception data memory 54 by the control data separated by the control data separation unit 55. The display data generation unit 27 generates display data for character programs. The display data and the video signal Video are subjected to processing such as screen switching and screen superposition in the switching composition unit 61 whose display screen is controlled by the display screen control unit 59, and are output to the display device 6.
[0020]
The display screen control unit 59 controls the display screen of the display device 6 and the like via the display data generation unit 59, the switching composition unit 61, and the external control terminal based on the program control data.
The switching composition unit 61
Switching function between video screen and display screen for text programs,
Superimposing function of video screen and display screen for text programs,
Fade function that fades in and out video screen and display screen for character program,
Flash display function such as blinking the video screen and the display screen for character programs or inserting the specified color alternately,
A sleep display function that displays that the video screen and the display screen screen for text programs are in a sleep state,
Designated color display function that displays the designated color in place of the video screen signal and the display screen for text programs
It has a guide display function for displaying internally generated guide information and the like in place of a video screen signal and a display screen for character programs.
[0021]
The control data separation unit 55 separates the control data from the decoded teletext data and inputs it to the display program selection unit 57, and inputs the reception channel selection data to the channel selection unit 56 via the control unit 62. The channel selection unit 56 issues a reception channel selection command to the reception unit 51 based on the reception channel selection data. Display control of the actual situation information of the competition is remotely controlled by sending out teletext data to which predetermined reception channel data is added from the center device 1.
[0022]
The display device 6 displays a large image such as a large flat display device such as a PDP or a liquid crystal projector in order to appropriately display a moving image such as live broadcast information and game character information such as odds to a large number of competition voting participants. Type display devices are deployed at various locations in the stadium.
[0023]
【The invention's effect】
The present invention is implemented in the form described above, and has the following effects.
The center device controls the information display screen that generates live information by video means from multiple cameras, etc., and the event ballot information necessary for voting by the attendees to be broadcast, and displays both information on the display device. The display terminal device selectively reads out the character broadcast program from the reception data memory by the control data separated by the control data separation unit, and the display data generation unit generates display data for the character program. The display data and the video signal are subjected to display screen control based on the separated program control data.
