DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) Embodiment Hereinafter, an embodiment will be described with an example in which a bidirectional communication system according to the present invention is applied to a satellite communication system.

(A-1) Configuration of First Embodiment and Operation of Each Unit FIG. 5 shows an overall configuration example of a satellite communication system 10 according to the present embodiment. Satellite communication system 10 of the present embodiment
Functions as an online shopping system.

In FIG. 5, the satellite communication system 10
Are client terminals 11A to 11N (where N is a natural number), server 12, communication satellite (or broadcast satellite) 1
3. The Internet 14 is provided.

[0010] Of these, client terminals 11A to 11N
And the server 12 are arranged in each user's house or the like on the ground and are connected by the Internet 14.

The communication satellite 13 is a broadcasting satellite capable of delivering data such as moving images to the client terminals 11A to 11N, and is located on a geosynchronous orbit of about 36,000 km above the sky, for example.

The communication satellite 1 in the satellite communication system 10
3 can be transmitted to the server 12, the server 12 can be transmitted to the client terminals 11A to 11N, and can be transmitted to the client terminals 11A to 11N. Is a communication satellite 13. Then, from the server 12 to the communication satellite 13
A wireless signal DS is used for transmission to the client terminal 11A to 11N, a wired signal ME1 to MEN is used for transmission from the client terminal 11A to the server 12, and a digital broadcast is used for transmission from the communication satellite 13 to the client terminal 11A to 11N. The radio signal DM as a wave is used. This radio signal DM
May be distributed as streaming data, for example, so that normal viewing can be performed immediately even when received from the middle.

Next, the client terminals 11A to 11A
A configuration example of a main part of N will be described with reference to FIG. Since the configurations of the client terminals 11A to 11N may be substantially the same, the description will be made assuming that FIG. 1 mainly shows the client terminal 11A.

(A-1-1) Configuration Example of Client Terminal In FIG. 1, the client terminal 11A includes a BS receiving unit 20, a browser unit 21, and a recording unit 23.

The BS receiver 20 includes a parabolic antenna, a BS tuner, and the like (not shown), and receives a radio signal DM transmitted from the communication satellite 13 by radio. The radio signal DM includes partial signals DM1, DM
2, DM3, etc. may be multiplexed. As this multiplexing multiplexing method, any multiplexing method such as time division multiplexing, frequency division multiplexing, and code division multiplexing may be adopted.

The combination of multiplexed partial signals (DM1, DM2, DM3 in the illustrated example) can be changed every moment.

However, among the multiplexed partial signals, there are further provided a commercial signal for transmitting moving image data and audio data for commercials of a product, and a sub-screen for the server 12 to interact with a user (for example, U1). A dialog signal for transmitting corresponding screen data is multiplexed.

A plurality of commercial signals may be multiplexed on one partial signal (for example, DM1).

The dialogue signal includes a catalog screen signal, a questionnaire screen signal, a purchase guide screen signal, a payment screen signal, and the like.

The catalog screen signal is a signal for displaying the catalog screen. The catalog screen includes an interactive part (a catalog of each product corresponding to each commercial signal multiplexed in the same partial signal (for example, DM1)). For example, a check box, an edit box, a radio button, etc.) are displayed on the screen.

Similarly, the questionnaire screen signal is a signal for displaying the questionnaire screen. The questionnaire screen displays a questionnaire (with interactive parts) related to commercial products, and the purchase guidance screen signal is a purchase guidance screen. In the purchase guidance screen, for example, interactive parts for inputting the type and quantity of the product desired to be purchased are displayed, and the payment screen signal is a signal for displaying the payment screen, For example, payment method (cash transfer, debit card, credit card, service point, etc.)
In the case of the installment payment, selection of the number of payments, selection of a card company, input of a card number, input of an electronic authentication number, desired date and time of delivery (with interactive parts) are displayed.

For example, depending on the payment method in the payment screen, the screen may be changed to a screen in which an address, a name, a contact address, etc. can be input. , You can simply enter your membership number and payment method.

In the illustrated example, three kinds of partial signals are distributed corresponding to the partial signals DM1 to DM3, and these commercial signals and dialogue signals are multiplexed in each partial signal.

The browser unit 21 connected to the BS receiving unit 20 is a part having a Web browser as a main functional element, and is used by being mounted on a television receiver in terms of hardware. It is a so-called set-top box with many. The browser unit 21 has a basic function of being connected to a television receiver and displaying an image corresponding to a Web page on a screen.

The browser unit 21 includes the reception / reproduction processing unit 2
5, a window system 26, a selection unit 27, and an intention display unit 28.

The reception / reproduction processing unit 25 is provided with an interpreter or the like to interpret and execute Web tags,
It has a function of decoding and reproducing each of the partial signals (such as DM1).

The window system 26 has a function of generating and operating a window according to the signal S11 supplied as a reproduction result from the reception / reproduction processing unit 25. The moving image and each control (check box, edit box, etc.) in the window are also generated by the window system 26 in response to the signal S11.

The generated window, moving image, and each control are displayed on a screen of a television receiver incorporated in the display operation unit 22. The display operation unit 22 includes an operation device (for example, a remote control operation device) such as a mouse and a controller in addition to the television receiver, and a user U1 watching the television receiver operates the operation device. Then, signal S13 is transmitted to selection section 27 or signal S15 is transmitted to intention display section 28 in accordance with the content of the operation.

The signal S13 is a signal for designating selection or non-selection of a partial signal (for example, DM1) to be reproduced by the reception / reproduction processing unit 25. The selection unit 27 causes the reception / reproduction processing unit 25 to respond to the received signal S13. Determine the partial signal to be reproduced.

Another signal S15 is a signal indicating the purchase intention of the user U1 who has watched the screen of the television receiver.
A message (wired signal) ME1 in a markup language format compatible with the hypertext system is transmitted according to the HTTP protocol. The message ME1 is
It is delivered to the server 12 via the Internet 14.

As a specific example of the markup language, BM
An extension of L (Broadcast Markup Language) or BML to make it compatible with general HTML can be used.

A recording unit 23 connected to the browser unit 21 by a signal S16 is a recording device such as a video tape recorder, and records a signal (moving image or audio) reproduced by the reception / reproduction processing unit 25. It can be reproduced when the user U1 desires.

However, the recording device transmits the wired signal ME1 in the same manner as when receiving and reproducing in real time, even if the recording is reproduced by the user U1, so that at least information such as a URL designating the server 12 is stored. It is necessary to record tags and extended BML files for using the hypertext system on the Internet 14.

Next, an example of the configuration of a main part of the server 12 capable of communicating with the client terminal 11A via the Internet 14 will be described with reference to FIG. The server 12 is managed and operated by, for example, a mail-order business.

(A-1-2) Configuration Example of Server In FIG. 3, the server 12 is a broadcast data supply unit 4
0, a receiving unit 41, a response processing unit 42, and a transmitting unit 43
And a wireless transmission unit 44.

The broadcast data supply section 40 is a section serving as an output source of broadcast data S33 which is a source of a commercial signal multiplexed in the partial signals DM1 and DM2 described above. Radio signal (DS) including broadcast data S33
1) can be continuously output as needed.

The receiving unit 41 is connected to the Internet 14
This is a part for receiving a wired signal MEX from any communication partner via the communication terminal. For example, the wired signal ME1 transmitted from the intention display unit 28 is finally received by the receiving unit 41 after being transferred on the Internet 14.

The response processing unit 42 connected to the receiving unit 14 by a signal S30 performs a response process according to the received wired signal MEX (eg, ME1), for example, according to the user U1's purchase intention. It is.

For example, when the user U1 indicates his / her intention to purchase the car A on the purchase guidance screen, a search is performed as to whether or not the car A is in stock, and the search result is returned to the user U1.
Is equivalent to the response process.

The database storing the stock information of the products may be installed in the server 12 or another server (not shown) on the Internet 14. However, in general, it is considered that the inventory information of each product is stored in a database on a server (a server different from the server 12) operated by the manufacturer or the seller of each product. In order to search for the presence or absence, the server 12 needs to access another server via the Internet 14.

The wired signal MEY transmitted by the transmitting unit 43 via the Internet 14 may include a wired signal for the access. The search result returned by the server is received by the receiving unit 41 as a wired signal.

The response data S32 to be transmitted to the user (for example, U1), such as the final search result, is not transmitted via the Internet 14, but is transmitted by the wireless transmission unit 44.
Is connected to the client terminal (for example, 11
A). The service quality is not guaranteed, and the response is made using the communication satellite 13 (for example, the purchase guide screen signal), rather than using the Internet, whose transmission speed fluctuates in accordance with the ever-changing communication traffic. Returning the data S32 to the client terminal (for example, 11A) is superior in terms of immediate response and communication quality (in the worst case, via the Internet 14 where quality is not guaranteed, packet loss during congestion). As a result, the response data S32 may not reach the destination client terminal (for example, 11A).

The moving image data and audio data output from the broadcast data supply unit 40 are data in the extended BML format corresponding to the hypertext system, and contain the purchase intention that the reception unit 41 receives from the client terminal (for example, 11A). Since the wired signal (for example, ME1) is also data in the extended BML format, the server 12 is a kind of Web.
You can think of it as a server.

In the present embodiment, the broadcast data supply unit 40 and the response processing unit 42 are mounted in the same server 12, but they may be mounted separately on separate servers. . In this case, broadcast data (for example, S33) and response data (for example, S32) wirelessly transmitted from separate servers are multiplexed in the communication satellite 13.

Next, the server 12 sends the broadcast data S3
3 and a radio signal (for example, DS
The configuration example of the main part of the communication satellite 13 for receiving 1) is shown in FIG.
It is as shown in FIG.

(A-1-3) Configuration Example of Communication Satellite In FIG. 2, the communication satellite 13 includes a receiving unit 30, a relay processing unit 31, a multiplexing processing unit 33, and a transmitting unit 32. I have.

The receiving section 30 receives the radio signals DS1 to DS3 transmitted from the server 12 by radio.

[0048] The received broadcast data and response data undergo predetermined relay processing in relay processing section 31 and are multiplexed.
After being subjected to the multiplexing process, the transmission unit 32 transmits the radio signal DM. The relay processing performed by the relay processing unit 31 may correspond to, for example, a so-called 3R function.

The server 12 sends the radio signal (DS1
, Etc.), the wireless signal DM (such as DM1) can be always delivered to each of the client terminals 11A to 11N.

Although only the server 12 is shown here as a server for transmitting to the communication satellite 13, the communication satellite 13 transmits radio signals (broadcast data and response data) from a plurality of servers as necessary. You may make it receive supply.

Hereinafter, the overall operation of this embodiment having the above configuration will be described.

(A-2) Overall Operation of First Embodiment In the satellite communication system 10 shown in FIG. 5, for example, the user U1 views a commercial signal corresponding to the partial signal DM3 using the television receiver of the client terminal 11A. It is assumed that At this time, the reception / reproduction processing unit 25 outputs the partial signal D of the multiplexed partial signals DM1 to DM3.
Only M3 is selectively reproduced.

Next, the user U1 operates the display operation unit 2
The signal S13 is output using the operating device 2 and the selecting unit 27
Causes the selected partial signal to be switched.

The selected partial signal is transmitted from the DM3 to the DM1.
, The reception / reproduction processing unit 25 outputs the partial signal DM1
To play.

At this time, what is first displayed on the screen of the television receiver is, for example, the catalog screen. On this catalog screen, several candidate product categories are displayed by, for example, still images or character strings, and the user U1 is allowed to select a desired product category by using the interactive parts and the operation device. ing. Here, when the user U1 selects an automobile as a candidate commodity classification, this selection is reflected in the signal S13, and the reception / reproduction processing unit 25 outputs a signal of each automobile (automobile A is one of them) multiplexed in the partial signal DM1. The commercial signal and the dialogue signal are sequentially reproduced.

An example of the screen display of the television receiver at that time is as follows.
For example, as shown in FIG. 4, a scene (moving image) in which the car A is running is displayed on a large main screen (window) F10, and purchased as a sub-screen (window) SF10 at a lower right position of the main screen F10. A guidance screen is displayed. At this time, as the sound, a sound such as a traveling sound of the car A or BGM, or a sound that conveys the performance or characteristics of the car A is output.

Of course, the position of the sub-screen SF10 does not need to be limited to the lower right position. The user U1 can change the position according to the operation of the operation device, or can change the position of the sub-screen SF1.
The display or non-display of 0 may be selected, and the size of the displayed sub-screen SF10 may be changed, or the main screen F10 may be erased to display only the sub-screen SF10. Is also good.

Such a change based on the wishes of the user U1 can be realized by the function of only the browser unit 21 without communicating with the server 12, but the user U1 has
It can be recognized as an effect of two-way communication.

In the example shown, the sub-screen SF10
Inside, the edit box EB as the dialogue component mentioned above
1, check boxes CB1 to CB3, send button PB
1, character strings ST1 to ST4 for transmitting the meaning of the interactive component to the user U1 are added to each interactive component.

The edit box EB1 is an area for inputting a character string. In the area, all functions necessary for editing a document can be used in principle.

Check boxes CB1 to CB3 are boxes that indicate selection by checking, and indicate non-selection by not checking. Unlike the radio buttons, the selection by the check box can be performed repeatedly.

Lastly, the transmission button PB1 is a kind of push button control. By operating the transmission button PB1, the wired signal ME1 containing the contents entered by the user U1 in each interactive part in the sub-screen SF10 is transmitted to the intention display section. 28
From the Internet 14.

The character string ST1 is a character string prompting entry of an address, a name, and the like in a nearby edit box EB1, and the character string ST2 is a character string indicating a car A as a product to be purchased. The character string ST3 is a character string indicating a car B as a product desired to be purchased, and
T4 is a character string indicating the car C as the product to be purchased.

Note that if it is difficult to convey information to the user U1 using such a character string in a normal television receiver whose resolution is lower than that of a display device such as a personal computer, use a sound. Or by increasing the size of each character string in the sub screen SF10.

When the user U1 enters necessary items such as an address and a name and checks the check box CB1 and operates the transmission button PB1 to transmit the wire signal ME1 indicating the desire to purchase the car A, the Internet The wired signal ME <b> 1 is transmitted via the server 14 and received by the server 12.

The server 12 receiving the wired signal ME1
Then, as described above, whether or not the vehicle A is in stock is searched, and response data S32 corresponding to the search result is returned to the client terminal 11A. Since the response data S32 is to be reproduced only by the client terminal 11A and must not be reproduced by another client terminal (for example, 11B), the reception / reproduction processing unit 25 provided in the browser unit 21 in the client terminal 11A. Only you should be able to play. This can be realized by using encryption technology. An example of such an encryption technique is, for example, SSL.

If the response data S32 indicates that the car A is out of stock, the purchase guide screen or the like is used to visually
Aurally, this is communicated to the user U1. in this case,
The procedure may proceed to a procedure such as a purchase reservation.

On the other hand, when the response data S32 indicates that there is stock, or when a deposit is paid for the purchase reservation procedure or the like, money must be transferred. here,
The above-described payment screen may be displayed in the main screen F10.

Thereafter, using the payment screen, for example, selection of a payment method, selection of the number of payments in the case of installment payment, selection of a card company, input of a card number, input of an electronic authentication number, and the like are performed online. Be executed. The confidentiality of the communication in this part can also be enhanced by using the above-described SSL or the like.

When the electronic settlement is completed normally, the delivery of the goods is performed.

In this example, since the product is a large car, it is considered that it is necessary to deliver the product directly to the user U1's house. However, if the product is small, the nearest convenience store or the pickup and delivery station of a transportation company is considered. Or the like, and the user U1 may receive it at any time after the desired date and time.

In the above example, the user U1 purchases the car A in real time while the radio signal DM1 is being distributed. However, if the recording unit 23 is used, the user U1 can always purchase the automobile A after the distribution. , Will be available for purchase online.

In this case, the operation of the client terminal 11A is described above in that the reception / reproduction processing unit 25 uses the signal S16 supplied from the recording unit 23 instead of the signal S10 supplied from the BS reception unit 20 as described above. After obtaining a commercial signal or a dialogue signal, for example, a main screen F1 as shown in FIG.
The only difference from the above is that 0 and the sub-screen SF10 are displayed on the screen of the television receiver.

Further, in the server 12 which receives the wired signal ME1 transmitted from the client terminal 11A, the wireless transmission of the commercial signal of the car A or the like has already ended at that time, and the commercial signal of another product is transmitted by the wireless signal (for example, DS1 ′), the response data S32 corresponding to the wired signal ME1 may be multiplexed and transmitted in the wireless signal DS1 ′. In order to enable such multiplexing, it is preferable that the line capacity of the radio signal DS1 'be given a margin in advance.

In a time period during which no commercial signal is broadcast, the response data S
Since there is a possibility that 32 will occur, if necessary, an independent channel may be prepared in advance exclusively for transmission of the response data S32 relating to a product other than the product being broadcast.

In any case, in the present embodiment, digital broadcasting from the communication satellite 13 is used for transmission of large-capacity data such as moving image data and data requiring immediacy such as response data. Low wired signal (eg, ME
By utilizing the inexpensive Internet 14 for the transmission of 1), good bidirectional communication can be realized.

In the case where not much immediacy is required, or when retransmission processing is executed if the data cannot be correctly transmitted to the client terminal (for example, 11A), the Internet 14 is also used for transmitting the response data S32. You may do so.

In this case, the dynamically generated response data S3
2 does not need to be accommodated in the digital broadcasting line, so that the processing in the wireless transmission unit 44 in the server 12
The processing in the multiplex processing unit 33 in the communication satellite 13 is simplified, and the load is reduced.

When the structure of the purchase guidance screen or the payment screen (arrangement of dialog components, contents of character strings, etc.) is a predetermined static one, the purchase guidance screen signal for displaying these is displayed on the screen. And the payment screen signal may be stored in a ROM mounted on the browser unit 21 or the like. This eliminates the need to multiplex a purchase guidance screen signal, a payment screen signal, and the like in a partial signal (for example, DM1).

The BS receiving section (excluding the parabolic antenna) 20 may be mounted in the same set-top box as the browser section 21.

(A-3) Effect of First Embodiment As described above, according to the present embodiment, it is possible to provide a satellite communication system having a high communication quality from the viewpoint of temporal fidelity of moving image reproduction. Can be.

Further, in the present embodiment, the communication quality can be improved from the viewpoint of the immediateness of the reaction, and a user-friendly interactive service can be realized.

(B) Second Embodiment Hereinafter, only the points of the present embodiment different from the first embodiment will be described.

In this embodiment, the satellite communication system is applied to a system for executing a voting-type game.

A voting-type game is a type of game in which a participant predicts a competitor who will win a race or the like, makes a voting ticket, and pays a dividend according to the voting situation and the actual game win / loss. There are horse racing, bicycle racing, and boat racing.

The payout may or may not be actually made or paid, but in this case, it is assumed that money is transferred using electronic payment, and a horse race (horse racing game) is assumed. This embodiment will be described with reference to FIG.

(B-1) Configuration and Operation of the Second Embodiment In this embodiment, instead of the commercial signal, a CG image (moving image) and a voice simulating an actual horse race relay are distributed, and the dialogue is performed. Instead of the traffic light, a frame order introduction screen, a race history screen of a running horse, a today's race result screen, an expected data screen, a betting ticket purchase screen, and the like are distributed.

The betting ticket purchase screen may be basically the same screen as the purchase guidance screen (SF10). When actually purchasing the betting ticket, the payment screen similar to the payment screen of the first embodiment is displayed. It may be used.

However, due to the nature of the voting-type game, a payout is paid to a participant depending on the game result. In this case, the payout is also executed by electronic payment.

In the horse racing game, the participant is a user (for example, U1) of each client terminal (11A to 11N).
The voting status according to each user's betting ticket purchase behavior is totaled on the server 12 side in real time and transmitted to each client terminal (for example, 11A) via the communication satellite 13.

The CG image simulating the relay of the horse race distributed in the present embodiment is, for example, a video similar to a video that can be seen in various places of an actual racetrack, such as a paddock, the first corner, and the front. It is preferable to distribute a plurality of images and display a video image selected according to the user's preference on the screen.

When the voting time ends, a winning determination table such as the determination table T2 in FIG. 6 is created based on the final total odds. This sets a random number range (0 to FFFF) according to the voting rate for each frame number and horse number. When creating the determination table T2, the area (for example, E1) on the table T2 is widened so that a horse with a higher voting rate and a lower dividend rate is more likely to win a prize. The area is narrowed so that the winning is difficult.

In the example shown in the figure, the horse of the third horse with the smallest payout ratio of 2.1 is associated with the area E3 on the determination table T2, but the area E3 is the largest area on the determination table T2. is there.

The determination of the race result is made in accordance with which area on the determination table T2 the random number value selected by the random number selection is located. For example, the numerical value EV31
If a random number value less than EV32 is selected as described above, it indicates that the horse with the horse number 3 has finished first.

Regarding the second place, except for the first place horse,
What is necessary is just to create the determination table T2 and perform the same processing as above.

The third and subsequent clothes can be determined by repeating the same operation.

Finally, the order of arrival of all the horses is determined,
The frame order is also determined.

As described above, the condition closer to the actual race can be obtained by counting and reflecting the condition of the horse, the weather, the compatibility of the riding ground, the rest period, and the expected value, not simply based on the dividend rate. Can be reproduced.

[0099] Accidents such as falling horses and early arrivals are also determined in the areas E8 and E1 shown in the determination table T2.
It is possible to reproduce using 0.

[0100] After all the elements constituting the race result are determined as described above, the development of the race and the production for the user (U1 or the like) to visually observe are determined. The race development may be selected from a plurality of development patterns by another random number lottery, or the horses in each finishing order may be sequentially applied to the development of each race determined in advance. Good.

When all the elements such as the race result, the race development, and the production are determined, the running time in the game is reached, and the CG and audio corresponding to the race result, the race development, and the production are distributed to the user (U1 or the like). And let them watch.

When the race watched by the user is completed, the voting result data corresponding to the race result is distributed to each user, and the settlement result after the race is displayed based on the distributed voting result data. .

As a result of the race, the winning user may pay the amount of money online to the financial institution to which the money is to be paid, or may use the money for the next race. For example, when U1) finally stops the race, it is necessary to settle the amount. For the settlement, electronic settlement is performed using the settlement screen described above.

In the case of a game that imitates public gambling in which money is exchanged as in the present embodiment, there is a problem of restriction on participation of voting participants. If the age of the child is checked, such a problem can be avoided.

(B-2) Effect of Second Embodiment According to the present embodiment, an effect equivalent to the effect of the first embodiment can be obtained in a voting-type game.

Therefore, in the present embodiment, it is possible to implement a voting-type game that is excellent in communication quality and immediacy and that allows many users to comfortably view and participate.

(C) Other Embodiments In the second embodiment, a voting-type game has been described as an example, but the present invention can be applied to an open prize or the like.

The system configuration of the open prize is basically the same as the above-mentioned voting-type game.

In other words, instead of the commercial signal, a sweepstakes program for providing a product attractive to the user (for example, U1) is broadcast via the communication satellite 13, and during the broadcast, each user is displayed using the sub-screen of the interactive signal. Apply for a sweepstakes. Then, on the server 12 side, each user terminal (for example, 1
Using the wired signal (for example, ME1) transmitted from 1A), the application contents of each user are processed and totaled.

[0110] If necessary, the realism may be enhanced by reflecting the application status or the like corresponding to the tally result in the broadcast content in real time.

After the end of the application time, the server 12 performs a lottery using the same random numbers as in the second embodiment, and announces the winner during the broadcast of the program. Announcing during the broadcast of a program can raise expectations.

In the voting-type game such as the above-mentioned horse racing game, the number of horses running is fixed statically in advance, but in the case of the open prize, an unspecified number of people watching the prize program are displayed. The number of applicants can fluctuate dynamically because the number of applicants arises from among viewers, and it is difficult to predict in advance how many applications will be applied. Is a problem.

In order to cope with this, a tentative predicted value regarding the number of applicants is set in advance and the predicted value is set in a numerical range (FIG.
The determination table T2 is set to 0 to FFFF in the case of
Is generated in advance, and if the actual number of applicants is smaller than the predicted value, after assigning each random number on the determination table to each actual applicant, The remaining area is a re-lottery area.

The random number lottery is repeated until a predetermined number of winners is reached. At this time, if the result of one random number lottery becomes the random number value in the re-lottery area, another random number lottery is unconditionally performed.
Once again, random number lottery will be executed.

On the other hand, when the number of actual applicants is larger than the predicted value, a plurality of applicants are assigned to one random number value and random number lottery is executed.

In this case, the number of winners may exceed a predetermined number of winners. In this case, for example, the random number lottery may be started again from assigning an applicant to a random number value, or the last random number lottery may be performed. The random number assignment and the random number lottery may be performed once again for the winners (plurality) who have won the random number lottery, and fine adjustment may be performed so that the number of winners and the number of winners completely match.
