Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a home voting device that allows pari-mutuel voting via a telephone line. The present invention relates to an at-home voting device that can display previously received data without leaving any data behind, and can reliably display race information, for example.

[Conventional Example] Conventionally, when purchasing a pari-mutuel betting ticket, it is common to go to an off-track betting ticket sales office or the racetrack where the pari-mutuel betting ticket is sold and purchase it with cash at the pari-mutuel betting ticket sales counter. Because it takes time and effort to purchase, for example, as part of fan service, a system has been proposed in which the pari-mutuel betting tickets can be purchased at Den J.

There are two types of telephone voting systems: the ARS method and the CR'L" method. In these systems, system subscribers sign a contract with the organizer, open a savings account in their name at a bank designated by the organizer, and At the same time, time deposits (e.g. face value 100,000, 2
00,000, 300,000, etc.), and on the other hand, the organizers keep the deposit as collateral and set that amount as the purchase limit for pari-mutuel betting. Due to this.

Fans in remote areas who are subscribers can purchase their desired pari-mutuel betting tickets over the phone.

[Problem M to be solved by the invention] By the way, in the above-mentioned telephone voting system, the AR8 method is such that the subscriber operates the buttons on the touch-tone telephone,
After connecting to the ticket-issuing computer for pari-mutuel betting, the details of the vote are input by operating a predetermined button. As a result, there was a problem in that it took a long time to complete the winning and winning voting process, and the telephone line was used for a long time. Moreover, because the number of telephone lines that can be connected to the ticket-issuing computer is fixed, there are times when the ticket-issuing computer cannot be connected, and especially near the race deadline, there may be a rush of purchasers. In some cases, pari-mutuel betting tickets cannot be purchased.

Furthermore, in the CR'r system, subscribers apply to purchase pari-mutuel betting tickets directly by telephone with staff at telephone voting stations. In this case, the staff member responds to the subscriber based on the winning horse data displayed on the cathode ray tube (CR'I'), receives an application for S horse voting, and purchases a voting ticket. However, since it is a verbal purchase, the purchase is more successful than the above ARS method. 6 Mistakes may occur when purchasing voting tickets, or it may take a long time to purchase due to difficulties in hearing, etc.
I had the same problem as above.

On the other hand, for fans when purchasing pari-mutuel betting tickets, information on approximate payout rates (such as odds) as well as horse racing newspapers are extremely important reference materials. However, those who go directly to the racecourse where the race is being held can find out the information on the Otsuzu bulletin board inside the racetrack, but those voting from home can refer to Otsuzu information from radio broadcasts, TV broadcasts, etc. I have no choice but to do it.

However, these broadcasts are often inconvenient for purchasers because they do not always provide necessary information such as the price at the desired time. In this regard, it would be convenient to provide the information necessary for pari-mutuel voting via teletext, but when receiving teletext,
The packet method is used for data transfer efficiency.
When an error occurs in a data packet, a teletext based on the data with the error is displayed, so that a portion of the displayed teletext may be missing. In the case of a horse racing program, for example, part of the race information may disappear and become invisible.

This invention was made in view of the problem described in item 1, and its purpose is to use the previously received teletext data as it is without leaving the data of the page where the data packet error has occurred when receiving teletext. To provide a teletext system capable of reliably displaying teletext messages while maintaining the content of teletext messages.

[Means for Solving the Problems] In order to achieve the above object, the at-home voting device of the present invention receives a teletext signal, stores the teletext data in the liAM section, and has the following functions: The receiving side of the teletext broadcast, which displays the teletext data stored in the meter on the screen of a television, etc., is equipped with a temporary RAM that stores one page of data when receiving the teletext broadcast. If a data packet error occurs during data storage, the data stored in the temporary RAM is not transferred to the RAM section, and the previously received data stored in the 1'lAM section is converted into a video signal. The gist of the system is to output the data to a television or the like.

[Function] The teletext system having the above configuration includes a storage means for storing data of information necessary for winning bets from the horse racing program, etc., and a screen of the television based on the information stored in the storage means. display processing means for displaying the information necessary for the event, the winning horse number of the predetermined winning horse betting, the purchase amount, and the PIN number (
A home voting device having a pari-mutuel betting setting means for setting a pari-mutuel betting ID), etc., and a pari-mutuel betting transmitting means for transmitting a pari-mutuel betting set by the pari-mutuel betting setting means to a pari-mutuel betting ticket sales side via a telephone line. 6 Then, when the teletext receiving means receives a teletext, the program data of the received teletext is stored in the RAM section. At this time, if a packet error occurs due to received data, the page data of the received program is not stored in the RAM section. Therefore, regarding the program page, RAM
The last received data is left in the section. That is, the RAM section always stores only the data of programs with no missing data, and does not store programs with missing data. therefore,
Since a complete image is displayed on the screen of a television or the like, for example, in the case of a horse racing program, part of the race odds display and the approximate payout rate will be missing, which will not interfere with the winning horse voting.

, a 21-bin connector +2d for video output, a connector 13a for RF output of the RF modulator 13, and a connector 16a for connecting a telephone line. As a result, the video signal from the ID1 section 12 is sent to the television via the video output connector 12b or the video output 21-bin connector 12d, and the video is displayed on the screen of the television. .

Next, the operation of the at-home voting device having the above configuration will be explained based on the flowchart of FIG.

First, the operator of the at-home voting device has already entered into a contract with the horse race organizer, and the at-home voting device and the organizer's pari-mutuel betting ticket sales center are connected via a telephone line. It is also assumed that the at-home voting device is connected to a telephone line and a television.

Here, when the 'I'It source switch 30 is turned on and the "power" key of the TV/character operation key group 27 is operated, and the "text broadcast" key is further operated, the remote control signal is used to control the pari-mutuel voting. The light is input manually via the light receiving section of the section 3 and the I/F section 14. The CPU 18 of the pari-mutuel betting control unit 3 outputs an instruction to receive teletext, and the instruction signal is sent to the L/F.
part 21, 1F part 2, part 2, and manual input to the teletext receiving part 2. Then, the tuner unit 5 selects teletext No. 43 of the channel corresponding to the operation of RKI) 4, and the 08
7 section 6 is inputted. 1) The teletext signal is reproduced into a data packet (tuning, data, check code) in the 87 unit 6, and the program data (program management data, page data) according to the data packet is stored in the internal buffer RAM. Furthermore, under the control of the CPU 9, the program data in the buffer RAM is read out.

The reception process of the teletext broadcast is performed (step correction 1), and the data of the first page of a predetermined program of the teletext broadcast, for example, a horse racing program, is stored in Tenbora January+AM7a (step 5T2).
). At this time, the CPU 9 monitors the flag of the 087 unit 6 to see if an error has occurred in the data packet (step 5T3). If the error has not occurred, one page of data stored in the temporary RAM 7a is transferred to the RAM section 7 (step 5T4).
Then, it is determined whether or not the transfer ends all pages of the teletext broadcast (step 5T5). For example, if the transfer process has not been completed for all pages of the horse racing program, the process returns to step ST2, the data of the second page of the horse racing program is stored in the temporary RAM 7a, and the same process as described above is performed.

Further, in step ST3, the temporary RAM 7a
If a data packet error occurs while the first page data is being stored in the temporary RAM,
The first page data stored in the RAM 7a is not transferred to the RAM section 7, and the process returns to step ST2, where the second page data of the horse racing program is stored in the temporary RAM 7a, and the same processing as described above is performed. In other words, the data of the page where the data packet error occurred is not stored in the RAM section 7, but
The data of the first page of the horse racing program received last time remains in the address corresponding to that page.

It is assumed that the first page of the horse racing program contains data on the odds information for the first loose horse.

Then, when a horse racing program is received, the first chance data is output from the DRT unit 6 and stored in the temporary RAM 7.
While it is stored in the DRT section 6 in the CPLI 9.
packet error flags are monitored.

If the flag is raised, temporary RAM 7a
The data on the first page of the horse racing program that was previously received is not transferred to the RAM section 7. Therefore, the data on the first page of the horse racing program that was received last time (the odds on the first page) is not transferred to the RAM section 7. It is left as it is.

Here, when an instruction to display the first page of the horse racing program is issued at I[P4, the cputg of the pari-mutuel betting control section 3 issues a request to import the data of the first page stored in the RAM section 7. The transferred data is stored in the RAM AlB 12, and the data is displayed. Subsequently, one display command is sent to the CPU of the teletext receiving unit 2 together with the display data.
9, the display data and the display command for the ID1 section 12 are sent to the CPU 9 in the shared memory section 8.
is memorized. As a result, the second loose number is displayed on the screen of a television or the like, but the displayed number is based on the previously received data due to a data packet error. In other words, the screen does not display the data from the first page where the data packet error occurred, and for example, part of the first page is missing, making it impossible to see the approximate refund rate. Nor.

[Effects of the Invention] As explained above, according to the at-home voting device of the present invention, when receiving a teletext broadcast, there is a temporary RAM that stores one page of the teletext broadcast, and a data packet error does not occur during storage. Sometimes, the teletext receiving means has a RAM section for storing data in the temporary RAM, and converts the teletext data stored in the RAM section into a video signal and outputs it to a television or the like; Race information from the horse racing program is displayed on the screen of the above television.

The pari-mutuel betting means has a function of outputting the pari-mutuel betting data of a predetermined race to the pari-mutuel ticket sales center via a telephone line and purchasing a single-win betting ticket. If no error occurs,
The data stored in the temporary RAM is transferred to City Records HAM.
If an error occurs in that data packet, the data stored in that Tenbola January+AM will not be transferred to the RAM section, so the data of the page at the time of the error will not be stored in the RAM section. Since the previously received data is left as is, text broadcasting can be reliably displayed on the screen of a television or the like without any portions of the teletext being missing.
