Description

[Detailed Description of the Invention] [Industrial application field] The present invention is intended to transmit text broadcast to an unspecified number of recipients so that specific text information can be viewed only by specific recipients. The present invention relates to a teletext system and a winning betting ticket home voting apparatus via a telephone line using the teletext system.

[Conventional example] Conventionally, when purchasing a winning betting ticket (winning betting ticket), it is common practice to go to the host racecourse or the off-site betting ticket office and purchase it in cash at the window of the winning horse betting ticket office. However, since it takes time to purchase the winning betting ticket, a system has been proposed in which the winning betting ticket can be purchased by telephone, for example, as part of fan service.

This phone voting system has ARS method and CRT method.
For these, the system subscriber makes a contract with the organizer side, for example, opens an ordinary deposit in the name of the person at the bank designated by the organizer side, and at the same time, time deposits (for example, 100,000, 200,000, 300,000 face value)
On the other hand, the organizer deposits the deposit as collateral and decides the amount as the purchase limit for the winning voting. This allows the subscriber, a remote fan, to purchase the desired winning betting ticket over the telephone.

[Problems to be Solved by the Invention] By the way, in the above-mentioned telephone voting system, when purchasing a winning betting ticket, information on a horse racing specialty paper and an approximate refund rate (odds and the like) are important reference materials. However, those who go directly to the racecourse that is being held can always know the odds information on the odds bulletin board in the hall, but those who are at home vote, for example, the odds information by radio broadcasting, television broadcasting, etc. I have no choice but to refer to.

However, these broadcasts do not always provide information such as odds necessary at a desired time, and thus have many inconveniences.

Further, upon purchasing the winning horse voting ticket, the fans refer not only to the forecast of the specialty paper, but also to, for example, the forecast of a forecaster. To receive such an expectation, you have to match the prospector, which is not possible for fans in remote areas. Incidentally, for example, such race prediction information (specific information) is valuable reference information that a purchaser of a winning horse ticket wants to obtain even by paying money, so that the general unspecified majority does not know. Is preferable. The same can be said for not only horse race prediction information but also fluctuation prediction information such as stock prices and futures trading prices.

Thereby, the video signal from the IDT unit 12 is sent to the television via the video output connector 12b or the video output 21-pin connector 12d, and the video is displayed on the screen of the television. .

Next, the operation of the home voting system having the above configuration will be described with reference to the flowcharts of FIGS. 5 to 7 and the display state diagrams of the television screen of FIGS. 8 to 10.

First, on the television broadcast transmitting side, specific character information is added to a predetermined teletext broadcast program to be superimposed on a television broadcast signal. The data of the specific character information is specified at the same address on the same page of the predetermined program. The home voting apparatus is connected to a telephone line and a television, and is connected to the horse race voting ticket sales center of the horse race organizer via the telephone line.

Here, in the flowchart of FIG. 5, when the power switch 30 is turned on, the “power” key of the TV / character operation key group 27 is operated, and further the “text broadcast” key is operated, The remote control signal is input via the light receiving section of the winning voting control section 3 and the I / F section 14. Then, an instruction to receive a text broadcast is output from the CPU 18 of the winning voting control unit 3, and the instruction signal is input to the teletext reception unit 2 via the I / F unit 21 and the I / F unit 22. Step 1
, A reception process of a teletext signal is performed. Then, the tuner unit 5 selects a teletext signal of a channel corresponding to the operation of the PRK 4 and inputs the channel to the DRT unit 6. The DRT unit 6 reproduces the teletext signal into data packets (tuning unit, data, check code), and program data (program management data, page data) based on the data packets is stored in an internal buffer RAM. Further, under the control of the CPU 9, the program data in the buffer RAM is read and the RAM
It is stored in the program RAM of the unit 7.

As described above, when the teletext data is received and stored in teletext receiving section 2 (step ST2), for example, RKP
It is determined whether or not an instruction to receive specific character information has been issued by operating the “specific information” key in step 4 (step ST
3). If the instruction is issued in RKP4, for example, CPU9
The interrupt signal stored in the internal register or in a predetermined area of the RAM unit 7 is output to the CPU 18 of the winning voting control unit 3. The command for generating the interrupt signal is transmitted by the winning voting control unit 3 when receiving the specific character information.
Output from CPU18, the internal register of CPU9 or R
It is stored in a predetermined area of the AM unit 7.

Subsequently, various program data stored in the RAM unit 7 is sequentially read out, and it is determined whether or not there is a plurality of data at the same address on the same page of the predetermined program (step ST).
Four). When a plurality of data at the same address is detected in the same page, an interrupt signal is output to the CPU 18 (step ST6), and the last of the plurality of data at the same address in the same page stored in the RAM unit 7 is output. Transfer processing of data (data of specific character information) other than data (text broadcast data) is performed (step ST7). When the transfer of all the specific character information data is completed, step ST1
Return to step ST8.

On the other hand, in the winning voting control section 3, an interrupt routine shown in FIG. 6 is started based on an interrupt signal from the teletext receiving section 2.

First, the CPU 18 performs a process of inputting specific character information data transferred from the teletext receiving unit 2 via the I / F unit 21 (step ST10). Processing for displaying on the screen is performed (step ST11). The display processing, for example, the specific character information data whose display position on the screen is determined is sequentially RA
It is stored in the M unit 15 (step ST12). When all of the specific character information data transferred from the teletext receiving unit 2 is stored in the RAM unit 15 in this way, the interrupt routine ends (step ST13).

Next, when an instruction to display the specific character is issued by operating the RKP4, a remote control signal corresponding to the operation is transmitted to the light receiving unit and the light receiving unit.
The data is input via the I / F unit 14, and the display routine shown in FIG. 7 is started.

Then, the CPU 18 of the winning voting control unit 3 performs a process for displaying the specific character information stored in the RAM unit 15, and outputs an interrupt signal to the teletext receiving unit 2 (step ST20). ). Then, the specific character information data subjected to the display processing is transferred to the teletext receiver 2 (step ST21), and the transfer is performed until the transfer of the stored specific character information is completed (step ST22).

On the other hand, in teletext receiving section 2, interrupt processing and display control processing are performed by the interrupt signal, and control for storing the transferred specific character information data (and display command) in shared memory section 8 is performed. . Then, the ID unit 21 converts the specific character information data stored in the shared memory unit 8 into a video signal or R, G, B signals (for 21 pins) and outputs them. Thereby, as shown in FIG. 8, the specific character information, for example, "01234567 ..." is displayed on the screen of the television.

On the other hand, when the predetermined program of the teletext reception is selected by the operation of RKP4, and when the specific character information data is included in the same address on the same page of the predetermined program, as shown in FIG. Assuming that data “0” as specific character information data and data “A” as normal text broadcast data are overwritten at the same address on the same page, Is transmitted, and then the data "A" is transmitted,
On the screen of the television, only the character "A" can be seen, and the specific character information "0 ..." cannot be seen. That is, as shown in FIG. 10, a normal teletext adapter displays only "ABCDEF ..." by teletext, and cannot see the specific text information "012345 ...".

As described above, by adding the specific character information signal and the like to the same address on the same page of the predetermined program of the teletext signal on the television broadcast transmitting side, the specific character information can be received only by the specific teletext receiver. As a result, it is possible to supply the specific information only to the specific person, and it is also possible to supply only an ordinary teletext to the unspecified majority.

Therefore, when the present invention is applied to the home voting apparatus, the television transmission transmitting side transmits, for example, a television broadcast signal in which specific character information (race prediction) is included in a text-based horse racing program. At this time, the specific character information data is included in the same address on the same page of the horse racing program. Note that the last data of the same address (data transmitted later at the same address) is a teletext program, the other data is specific character information, and the data of the same address may be two or more.

As a result, in the teletext receiving apparatus receiving the horse racing program, display processing is performed based on the last data (horse racing program), so that the specific character information cannot be viewed. On the other hand, in the home voting apparatus, when an instruction for specific character information is issued by RKP4, the specific character information data included in the same address on the same page of the horse racing program is detected, and the specific character information data is stored. In addition, display processing based on the data is performed by a predetermined operation. Therefore, the specific character information can be provided only to the user of the home voting device. This is convenient when used for the purpose of supplying information to a specific person as in the case of a race prediction. Can be purchased.

The at-home voting apparatus can perform a winning voting to a winning voting ticket sales center for horse racing through a telephone line.

[Effects of the Invention] As described above, according to the present invention, a predetermined program of a teletext signal includes a plurality of data (specific character information, etc.) at the same address on the same page of the program on the television broadcast transmitting side. The teletext system has a function of receiving teletext, detecting a plurality of data (specific character information) having the same address on the same page, and storing the detected specific information data. And a function of controlling the display of the specific information data, so that when the teletext is received, the specific character information can be obtained in addition to the normal teletext when the teletext includes the specific character information. There is an effect that the specific character information cannot be obtained on the ordinary teletext receiving side of the unspecified majority.
Therefore, when the teletext system is applied to a home voting device, for example, a race prediction of a prospective trader can be added to a horse racing program of a teletext broadcast. You can get the race prediction.
