## Title
System and method for relaying race information

## Abstract

A system and method for relaying race information related to a plurality of races, such as horse or greyhound races, typically held at racetracks. The system includes a computer system that receives and stores current race information from the plurality of races. The system also includes a remote device coupled to the computer system. A user operating the remote device can view race information and place wagers on the races. The method begins by the computer system sending initial race information to the remote device. As current race information is received from the racetracks, the computer system compares current race information with the initial race information sent to the remote device. The computer system then sends updated race information to the remote device. This updated race information includes only race information that has changed since the initial race information was sent from the computer system to the remote device.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the Figures, wherein like numerals indicate like parts throughout the several views, a system for relaying race information related to a plurality of races is shown at 10 in FIG. 1.
Each race of the plurality of races is typically located on a racetrack 12. Commonly, these races are contests between horses driven by jockeys or between greyhounds chasing an artificial rabbit lure. However, other types of races may be utilized by the system, such as races between humans, automobiles, etc., with or without a racetrack.
Each race typically has a plurality of entrants. It is routine, especially with horse and greyhound racing, for spectators to place wagers on the performance of the entrants. This wagering typically occurs before each race begins or before a series of races begin. Therefore, the term “race”, as used herein, may be extended to include a next race to be run. The race information relayed by the system 10 may include, but is not limited to, one of more of the following: odds of winning associated with each entrant, track conditions, changes related to the race, exotic odds information, wager pool totals, combination wager odds, will pays information, race results, and exotic results.
Wagering on horse and greyhound races most often follows a pari-mutuel gambling model. In pari-mutuel gambling, the winners divide, in proportion to their wagers, the total amount bet, minus a percentage for track operators, taxes, etc. As betting on the several entrants progresses, the total mount bet, as well as the amount bet on each entrant changes. Thus, the payout odds for each entrant changes as well.
Various bet types are common in pari-mutuel horse and greyhound gambling. For example, a “win” bet will pay off if the entrant wins (finishes first) the race, a “place” bet pays if the entrant comes in first or second, and a “show” bet pays if the entrant finishes in the top three. Other exotic odds bet types are also commonly available to pari-mutuel gamblers. Examples of exotic odds bets types include a “daily double” bet where the object is to pick the winners of two consecutive races (typically the first two races of the day), an “exacta” (or “perfecta”) in which the top two finishers, in finishing order, must be picked, or a “trifecta” where the top three finishers are picked in finishing order.
To accomplish the complex calculation of odds and payout amounts for the multitude of available bet types, each racetrack 12 employs a calculating system known as a totalisator 13, commonly abbreviated as a tote 13. Each tote 13 tracks the amount of money wagered on each entrant in each race and the form of each wager (win, place, show, part of a trifecta, etc.).
The system 10 of the present invention includes a computer system 14 in operative communication with a tote 13 associated with each racetrack 12. In one embodiment of the present invention, the computer system 14 includes at least one server computer 16 located at a central location 18. However, those skilled in the art will realize that the computer system 14 may include more than one server computer 16 at the central location 18 or multiple computers 16 spread out at a plurality of locations.
A remote device 20 is coupled to the computer system 14. The remote device 20 may be implemented as a computer terminal, a personal computer, a telephone, a laptop computer, a notebook computer, a portable gaming device, a personal digital assistant, or any other suitable device. The remote device 20 includes an output interface 44 to deliver information to a user 48 and an input interface 46 for the user 48 to input commands or selections. The output interface, in one embodiment, includes a display 24 for viewing the information. The input interface 46 may include a keyboard, keypad, mouse, touchscreen, etc. The remote device 20 allows the user 48, via the input interface 46, to select at least one race to view from a larger set of races. The user 48 can also select a plurality of races to view simultaneously.
The system 10 further includes a communication network 22 for coupling the computer system 14 and the remote device 20. The network 22 utilizes hard-wired transmission of data, wireless transmission of data, or a combination of hard-wired and wireless transmission of data. Examples of networks with hard-wired transmission of data include, but are not limited to, the plain-old telephone service (POTS), fiber-optic communication cables, and Ethernet cables. Examples of networks with wireless transmission of data include, but are not limited to cellular telephone networks, personal communication system (PCS) networks, Wi-Fi networks, or Bluetooth.
Referring to FIG. 2, in one embodiment, the computer system 14 includes a customer account manager (CAM) 30 implemented in software. The CAM 30 manages all financial activities associated with a wagering account associated with the user 48. The CAM 30 is in operative communication with a risk management system 32 and a funding system 34. The risk management system 32 assists the CAM 30 in determining whether to accept a wager. The funding system 34 acts as an interface between funding agents 36, such as banks and other financial institutions.
The computer system 14 may also include a database 38 and a wager manager 40 in operative communication with each other and the CAM 30. In one embodiment, the database 38 is a structured query language (SQL) server. However, other types of databases are well known to those skilled in the art and can be implemented instead of the SQL server. The database 38 stores data related to the wager account of the user 48.
The wager manager 40 operatively communicates with a tote interface 42, which is in operative communication with the tote 13 at each racetrack 12. In one embodiment, only wager-related data is sent from the wager manager 40 to the tote interface 42. No user-specification information, such as an identity of the user 48, is sent to the tote interface 42. Therefore, the totes 13 at the various racetracks 12 never know the identity of the user 48 placing the wager and the wager is treated as an anonymous cash transaction.
Referring now to FIG. 3, in a first step 50, the computer system 14 continuously receives and stores current race information from the race tracks 12. This race information includes, but is not limited to, the odds of winning associated with each entrant, track conditions, changes related to the race (scratched entrants, etc.), exotic odds information, wager pool totals, combination wager odds, will pays information, race results, and exotic results.
In a second step 52, the computer system 14 sends initial race information to the remote device 20 and in a third step 54, the remote device 20 receives the initial race information. The initial race information is a first transmission of race information. As the wagering prior to a race proceeds and the race progresses, the race information changes. For example, odds for each entrant typically changes, some entrants may be scratched, the weather conditions at the racetrack 12 may change, etc. In a fourth step 56, the computer system 14 compares the initial race information sent to the remote device 20 with the current race information. Based on this comparison, the computer system 14 generates updated race information The updated race information includes only race information that has changed since the initial race information was sent. The computer system 14 may filter the updated race information based on what races have been chosen by the user to view at the remote device 20. The computer system 14 then prepares a data package containing the updated race information at periodic intervals. The data package includes a data message sequence which identifies the race information which has been updated. In a fifth step 58, the data package containing the updated race information is then transmitted to the remote device 20. The updated race information is received by the remote device 20 in a sixth step 60.
The computer system 14 continues repeatedly in this fashion. In a seventh step 62, the updated race information is compared with the current race information. Further updated race information, including only the race information that has changed, is generated. The further updated information is sent from the computer system 14 to the remote device 20 in an eighth step 64. In a ninth step 66, the remote device 20 receives the further updated race information. By only sending the race information that has changed since the transmission of the data package, bandwidth of the network 22 is conserved.
Some race information may be more critical to the user 48 than other race information. For instance, the odds of winning for each entrant may be of greater importance than track conditions. Therefore, the race information may be broken into more than one piece of data, such as first and second pieces of data. The first piece of data is sent at a first periodic interval and the second piece of data at a second periodic interval. For example, the first piece of data (e.g. odds of winning for each entrant) is sent every 5 seconds, while the second piece of data (e.g. track conditions) is sent every 60 seconds. Even when breaking the race information down into more than one piece of data, the computer system 14 still sends only race information that has changed since the last transmission of data.
As shown in FIGS. 4-17, the display 24 of the remote device 20 displays a unified user interface 26 for simultaneously showing the race information for each of the plurality of races. The unified user interface 26 allows the user 48 to select the plurality of races that are to be displayed from a larger set of races. The unified user interface 26 also allows the user 48 to select a plurality of racetracks 12. Each of the plurality of races is located at one of the plurality of racetracks 12. In one embodiment, the unified user interface 26 includes a plurality of strips 28. Each strip 28 corresponds to one of the plurality of racetracks and displays the updated race information pertaining to at least one race located at the corresponding racetrack 12. As shown in the FIG. 4, each strip 28 includes each entrant's current odds of winning the next race, the current track conditions, and the payouts for win, place and show. However, the strips 28 of the unified user interface 26 may be configured to display other race information.
The unified user interface 26 allows the user 48 to quickly access all previous race results from any particular racetrack 12. Each strip 28 includes an “ALL” button adjacent the payouts. In one embodiment, when the “ALL” button is selected via the input interface 46, an “all results” popup window appears, as shown in FIG. 5. The “all results” popup includes, among other things, the winner of the race and where the other horses placed, the payouts for a win, place and show and the payouts for the exotics.
Referring to FIG. 6, the unified user interface 26 allows the user 48 to review exotic results from previous races at each racetrack 12 by selecting the “ER” button adjacent the payouts. After a particular race is selected, an “exotic results” popup window appears, as shown in FIG. 7. The information in the “exotic results” popup includes the results/payouts for the exotics.
The “exotic menu” feature, as shown in FIG. 8, is accessed by selecting the “EX” button adjacent each entrant's current win odds. The “exotic menu” allows the user 48 to access specific exotics (i.e., wagers typically involve the user selecting a combination of horses in one or more races such as so-called Exactas, Trifectas, Quinellas, Daily Doubles, etc.) information for the associated racetrack 12 and race(s). Referring to FIG. 9, in one embodiment, an “exotics” popup window allows the user to access to view the amounts wagered for a particular exotic wagering category (e.g. the so-called Exacta).
FIG. 10 shows a “changes” popup window accessed through the “LC” button adjacent the track conditions on each strip 28. The “changes” popup window allows the user 48 to review information that has recently changed before a race, such as race conditions and whether an entrant is scratched before the race.
The unified user interface 26 also allows the user 48 to view pool totals for win, place, and show. As shown in FIG. 11, the user 48 selects the “PT” button adjacent each entrant's current win odds. The user 48 can then select whether to view pool totals for win, place, or show. Once selected an appropriate popup window is opened. FIG. 12 shows a “win pool totals” popup displaying allowing the win pool totals for the race including the amount bet on each entrant in the race.
A “program” popup window, as shown in FIG. 13, is accessed when the user 48 selects the entrant's current win odds section of the strip 28. The “program” popup allows the user 48 to view the specific, detailed information that would normally be available in a race program. For example, the user can see the number of horses racing, their names, their win percentage, any concessions or allowances (weight allowances, apprentice allowances, etc.), the jockeys, their weights, etc., for each race.
Referring now to FIG. 14, the user 48 can access a “will pays” by selecting the “WP” button adjacent each entrant's current win odds on strip 28. The “will pays” menu, shown in FIG. 15, allows the user 48 to view and select various pay features such as, but not limited to, daily doubles. For example, the user 48 can access the payout for a second race of a daily double after the first race has been run.
The remote device 20 allows the user 48 to place a wager on at least one of the races being viewed on the display 24. As shown in FIG. 16, a “wager pad” popup window is available via the unified user interface 26. Wager information is sent from the remote device 20 to the computer system 14. The computer system 14 then registers the wager with the tote 13 at the appropriate racetrack 12.
Racetracks 12 typically provide live video and audio feeds of their races, which are broadcast throughout the facility of the racetrack 12. These video and audio feeds are usually simulcast at other racetracks 12, off-track betting facilities, casinos, etc. The remote device 20 also allows the user 48 to view these live video feed and/or audio feeds of a selected race.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. The invention may be practiced otherwise than as specifically described within the scope of the appended claims.
