1. Field of the Invention
The present invention relates to a communications concentrator/multiplexer and, more specifically, to a system and method for the safe, secure and reliable transmission of wagering and/or pari-mutuel wagering information between a Central Wagering Hub and a plurality of downstream devices through a Terminal Network Interface system.
2. Description of the Background
The present invention is generally related to wagering/gaming devices, wagering networks and more specifically, to communications systems utilized with gaming devices and gaming device networks that enable and act as an interface between wagering peripherals and/or other downstream devices and processing centers (Hubs). More particularly, this invention relates to methods and apparatus for providing the secure and reliable transmission of wagering information between a plurality of wagering peripherals and/or terminals and at least one central processing center or central wagering hub.
The current state of the art in the industry for this type of product is the Terminal Network Interface One (“TNI-1”) which is a highly versatile, cost effective communications device that is used exclusively to interface serial wagering peripherals (up to 150 terminals) to a localized processing center or hub. The TNI-1 utilizes a high encryption algorithm and can safely use the Internet as an inexpensive communications alternative, while at the same time guaranteeing the secure, non-repudiated transmission of wagering transactions. The reliability of the TNI-1 is achieved through its built-in modem/ISDN dial-up backup along with the secure operating system. At present the technology and methods utilized by the TNI-1 for the safe and secure transmission of wagering information between the wagering peripherals and the central processing centers are limited in the types of peripheral and/or downstream devices that they are capable of connecting to in both type and quantity. For instance, the current technology that is employed by the TNI-1 only has the capability of providing serial type connections to a very limited quantity of serial type peripheral devices.
The TNI-1 is capable of communicating using a variety of protocols including but not limited to, TCP/IP over Ethernet and asynchronous Point-to-Point Protocol. For TCP/IP Connectivity via Ethernet, the TNI-1 supports the use of static IP, DHCP, and PPPOE addressing. The Ethernet port operates over both 10 and 100 Mbps connection rates. For TCP/IP Connectivity via PPP the PPP interface of the TNI-1 can be used to either dial a private modem pool or a public internet ISP. A limitation of this PPP interface on the TNI-1 is that it requires the use of Plain Authentication Password (“PAP”). The TNI-1 does not support the Challenge Handshake Authentication Protocol (“CHAP”). The PPP configuration for the TNI-1 also requires the phone number of the modem pool, the username and password, and the baud rate of connection from the TNI-1 to the modem.

The present invention, the Terminal Network Interface 2 (“TNI-2”) is a communications concentrator or a communications multiplexer that is specifically designed for use in association with wagering and pari-mutuel wagering applications and the secure and reliable transmission of information between a plurality of wagering peripherals and a central wagering hub. The TNI-2 is a highly versatile, cost effective communications device which is used to interface a plurality of wagering peripherals to at least one central processing center (hub). Utilizing the latest high encryption algorithm, the TNI-2 is capable of safely utilizing the Internet as an inexpensive communications alternative, while guaranteeing secure, non-repudiated wagering transactions. The reliability in the TNI-2 is achieved through its built-in intelligent modem/ISDN dial-backup along with a secure operating system.
The TNI-2 was invented to solve a variety of problems that the original TNI-1 was unable to resolve. The original TNI-1 was designed for use in very small locations with very few peripheral terminals (typically less than 30 terminals). Additionally, the only type of terminals that the TNI-1 was capable of supporting are legacy serial terminals. New terminals have been and are currently being developed that rely on the TCP/IP protocol instead of serial. However, the only way for these new TCP/IP devices to communicate with the Central Wagering Hub was through a very expensive server based communications concentrator. Furthermore, this server based communications concentrator required the use of additional expensive networking equipment in order to interface to the communications network. The TNI-2 solves this problem by providing a cost effective method for the new TCP/IP terminals to interface with the central wager processing center.
The TNI-2 also provides the additional capability of addressing the needs of locations that either require or desire racing related television displays to be generated. Prior to the development of the TNI-2, in order to fulfill this need, a separate server was required to convert a data stream from a Central Wagering Hub into a video output for use by peripheral devices. The TNI-2 has solved this problem by integrating this process and thus eliminating the additional expense and complexity involved with an external video generator. The TNI-2 provides the additional advantage of being capable of supporting thousands of TCP/IP devices and serial devices whereas the original TNI could only support 5 downstream serial lines.
An exemplary method for using the TNI-2 to facilitate the processing and acknowledgement of wagering information between a plurality of peripheral devices and a central wagering hub involves an end user inputting a message into a peripheral device. The peripheral device then transmits this message to the TNI-2 where the TNI-2 inserts an appropriate data field into the message which will later allow the Central Wagering Hub to identify the specific source peripheral device from where the message originated. The TNI-2 then proceeds to transmit this message, now with the additional data field inserted, to the Central Wagering Hub via a TCP/IP network. Upon receipt of this message, the Central Wagering Hub processes this message and generates an acknowledgment message to be transmitted back to the TNI-2 via a TCP/IP network. The Central Wagering Hub then transmits the acknowledgment message back to the TNI-2. The TNI-2 then processes the acknowledgment message from the Central Wagering Hub in order to determine from which specific peripheral device the transmission originated. Upon determination of the appropriate downstream device, the TNI-2 then transmits the acknowledgment message back to the peripheral device from which the message originated. The originating peripheral device then processes the returned data.
A second exemplary method for using the TNI-2 to facilitate the processing and acknowledgement of information between a plurality of peripheral devices and a central wagering hub involves a peripheral device generating a message independently without any end user input. The peripheral device then transmits the message to the TNI-2 where the TNI-2 inserts an appropriate data field into the message which will later allow the Central Wagering Hub to identify the specific source device from where the message originated from. The TNI-2 then proceeds to transmit the message, with the additional data field, to the Central Wagering Hub via a TCP/IP network. Upon receipt of the message, the Central Wagering Hub processes the message and generates an acknowledgment message to be transmitted back to the TNI-2 via a TCP/IP network. The Central Wagering Hub then transmits the acknowledgment message back to the TNI-2. The TNI-2 then processes the acknowledgment message from the Central Wagering Hub in order to determine from which specific peripheral device the transmission originated. Upon determination of the appropriate downstream device, he TNI-2 then transmits the acknowledgment message back to the peripheral device from which the message originated. The originating peripheral device then processes the returned data.
A third method for using the TNI-2 to facilitate the processing and acknowledgement of wagering information between a plurality of peripheral devices and a central wagering hub involves a message originating at the Central Wagering Hub either independently or as a result of some user input. The Central Wagering Hub then transmits the message to the TNI-2 where the TNI-2. The TNI-2 then determines which specific downstream peripheral device the message is intended for and proceeds to transmit the message to said specific device. Upon receipt of the message, the peripheral device processes the message. If necessary, the peripheral device will generate an acknowledgement message to be sent back to the Central Wagering Hub through the TNI-2 via the same pathway.

One advantage of the present invention is that it provides the ability to connect to and communicate with a variety of downstream peripheral devices, requiring a variety of connection types, through a single terminal network interface. For example, the TNI-2 is capable of total connectivity, meaning that through a single TNI-2 the Central Wagering Hub can communicate with serial, Ethernet and wireless peripheral devices. Another advantage of the TNI-2 is that it is placed, on site, at the location where the peripheral devices are located and remote from the location where the Central Wagering Hub is located. The types of downstream devices that the TNI-2 is capable of providing connectivity to include but are in no manner limited to legacy serial devices such as Ticket Issuing Machines (TIMS), Display Processors, Infield Display Controllers, Inter-Track Wagering (“ITW”) lines, DecWriters, Printers, administrative devices, etc.

The LCD/Keypad User Interface 117 is the method by which the user of the TNI-2 205 monitors and configures the TNI-2 205.
The Video Card(s) 106 may be used to generate the graphics from a frame buffer to display on multiple televisions or monitors 119. The multiple televisions or monitors 119 attach to the TNI-2 205 via a standard video cable and display video output.
The USB to video converters 122 allow for a less expensive solution for supporting video graphics displays, and provide the ability to increase in the number of monitors that can be connected through the TNI-2. The video cards 106 can only support 2 monitors while the USB to video converters are capable of supporting 16 monitors.
The Internal Hard Drive 108 may be used for the storage of large amounts of files for use by downstream devices.
The Power Supply 102 may be capable of working on either 110 or 120 volts. The TNI-2 205 converts the power into 5 volt power for the TNI-2 205 to use.
The TCP/IP network 203 can be any IP compatible network. Examples of this include, but are not limited to, Ethernet (10, 100, 1000 Mbps), serial/modem connections via the point-to-point protocol (PPP), 56k DDS, T1, Frame-relay, MPLS, Internet VPN's or any combination of the above. The TNI-2 205 is an intelligent concentrator or multiplexer. The TNI-2 205 processes messages from a Central Wagering Hub 201 and determines which downstream device to send the message to. When a downstream device sends a message to the Central Wagering Hub 201, the TNI-2 205 inserts a proper data field into the message so that the Central Wagering Hub 201 knows the source device the message originated from. The upstream connection to the system is a TCP socket to a server within the Central Wagering Hub 201. The connection can be initiated over an integrated Ethernet connection 204A in the TNI-2 205 or via a PPP connection 204B by an attached modem or terminal adapter. The downstream devices on the TNI-2 205 may include, among other devices, serial devices 207A-207C via a RS232/422/485 interfaces 206A-206C, TCP/IP devices 211A-211B (wired and/or wireless) via an Ethernet interface 208 and attached video display devices 213 via any standard video connector.
A Serial Terminal 207A is an end-user device for which a teller at a remote site may place a wager or an unattended device where a patron may place a wager without interacting with a teller. Serial terminals 207A are polled protocols over a RS422/485 4 wire connection 206A. Up to 30 polled protocols may exist on one serial port on the TNI-2 205.
A Serial Administrative Device 207B is a computer located on-site at a remote location and is used to monitor, control and report on the operations of the wagering devices at the location. Examples of such control include allowing the terminals to accept wagers, creating reports for the mutual department and other such interactions required to operate a wagering location. The administrative device is connected to a TNI-2 205 over a serial connection 206B.
There are often requirements of a plurality of miscellaneous serial devices 207C at a wagering location. These miscellaneous serial devices 207C may include printers; an external odds feed for third party entities to process, and various other types of serial devices. These miscellaneous serial devices 207C are connected to a TNI-2 205 over a serial connection 206C.
For a plurality of downstream TCP/IP terminals 211A to interface to the TNI-2 205, an Ethernet Network 209 interconnects the TCP/IP Terminals 211A and the TCP/IP Administrative Devices 211B to the TNI-2 205. These TCP/IP Devices 211A-211B are connected to the Ethernet Network over Ethernet connections 210A-210B where connections 210A-210B can be either wired or wireless Ethernet connections.
A TCP/IP Terminal 211A is typically an end-user device for which a teller at a remote site may place a wager or an unattended device where the patron may place the wager without interacting with a teller. Peripheral TCP/IP terminals 211A communicate with the TNI-2 205 over a TCP socket, wherein the TCP/IP terminal 211A is the TCP client and the TNI-2 205 is the TCP server.
A TCP/IP Administrative Device 211B is a computer at a remote location which is used to monitor, control and report on the operations of the wagering devices at the location. Examples of such control include, but are not limited to, allowing the terminals to accept wagers, creating reports for the mutual department and other such interactions that are required to operate a wagering location. The TCP/IP Administrative Device 211B is connected to a TNI-2 205 over a TCP socket, where the TCP/IP Administrative Device 211B is a TCP client and the TNI-2 205 is a TCP server.
One of the optional interfaces available on the TNI-2 205 is the ability for the TNI-2 205 to generate a dynamic video image such as an odds display which is then outputted to a Video Display Device 213. The Video Display Device 213 can be a television, a monitor or any other device capable of displaying video. The TNI-2 205 has an integrated internal character generator 703 that is able to process a data stream from the Central Wagering Hub 201 and generate a dynamic video image to be displayed on the Video Display Device 213. Numerous video display devices 213 can exist on the TNI-2 205, each displaying an independent dynamic video image.
The Ethernet IP Interface 301 handles the IP addressing of the Ethernet Interface 109. Depending on the mode of the configuration, this process handles the assignment of IP addressing information for Static IP, Dynamic Host Configuration Protocol (DHCP) or the Point-to-Point Over Ethernet (PPPOE) IP addressing methods.
The Ethernet Interface Monitor 302 controls the Ethernet Interface 109 by regularly monitoring the Ethernet Interface 109 to determine its state. If the state of the Ethernet Interface 109 is not suitable for use (i.e., no IP address or no connection to an Ethernet Network) then the Ethernet Interface Monitor 302 signals the Serial/PPP Interface Monitor 305, if present, to attempt to establish a connection via the Modem/Terminal Adapter 303.
A Modem or ISDN Terminal Adapter 303 can also be attached to the TNI-2 205 to provide a dial-up connection to a remote Central Wagering Hub 201. The modem 303 communicates to the TNI-2 205 over a serial connection. The Serial/PPP Interface 304 handles the lower level communications layer of running TCP/IP over a serial connection.
The Serial/PPP Interface Monitor 305 monitors the status of the Serial/PPP Interface 304 to a remote network. If a link is broken (i.e. the modem disconnects), this module will attempt to reconnect the modem 303 to the remote network. If the Ethernet Interface Monitor 302 determines the Ethernet IP Interface 301 is not suitable for network connections, then the Serial/PPP Interface Monitor 305 can initiate a dial-up connection automatically in order to try to establish a connection. This method of automatic dial-up backup is used to keep the modem 303 connected as little as possible in order to reduce costs.
The TCP/IP Subsystem 306 handles the OSI layers 3 through 4 of the TCP/IP communications protocol.
The Central Hub TCP Socket Client 307 establishes a TCP socket connection to the TCP server which is located in the Central Wagering Hub 201. If a TCP session becomes disconnected, then the Central Hub TCP Socket Client 307 automatically attempts to reconnect.
The TCP Message Processor 308 converts the data stream that TCP provides into datagram oriented messages. This is accomplished by using the SOH/EOT/ETX/DLE datastream break characters to interpret incoming stream data into independent data blocks.
The Encryption and Decryption engine 309 decrypts incoming packets and encrypts outgoing packets. The TNI-2 205 can be configured to use any encryption protocol such as the Advanced Encryption Standard (AES), Secure Socket Layer (SSL) or the Transport Layer Security (TLS) encryption protocols.
The Downstream Device Message Router 403 contains a routing table that knows the location of each type of downstream device, whether it is a Serial device 207A-207C, an Ethernet device 211A-211B, an Internal Character Generator 406 or some other type of device. This module assures the messages are routed to the proper device.

A Serial Polled Terminal 207A is a device from which wagers are placed. The Serial Polled Terminal 207A interfaces to the TNI-2 205 over a serial connection.
The Serial Administrative Device Interface 502 formats messages from the Downstream Device Message Router 403 in order to communicate to a Serial Administrative Device 207B. This communications protocol includes adding data windowing capability as well as checksums in order to make the communications to the Serial Administrative Device 207B quicker and more reliable.
The Serial Administrative Device 207B is a computer which runs a program to interface to the TNI-2 205 over a communications link. The Serial Administrative Device 207B is used to control racing as well as to process reports.
The Serial Stream Line Interface 503 is a raw serial stream message switcher. Any message from the system Central Wagering System is directly transmitted on a local serial interface on the TNI-2 205. Likewise, any data received on the serial port is directly forwarded to the Downstream Device Message Router 403, and ultimately to the Central Wagering Hub 201.
The Downstream Serial Device 207C can be any serial device that communicates in a raw manor to the Central Wagering Hub 201 system. An example of this could be a serial printer.
The Ethernet Administrative Device Message Processor 602 formats the data messages received from the Downstream Device Message Controller 403 into a format intended for the Downstream Ethernet Administrative Device 211B to understand.
The Encryptor/Decryptor 603 optionally decrypts data coming from the Downstream Ethernet Devices 211A-211B and encrypts data going to the Downstream Ethernet Devices 211A-211B.
The Downstream Ethernet Device Message Router 604 keeps track of all of the incoming TCP/IP connections and associates each connection with the appropriate Ethernet Terminal 211A or Ethernet Administrative Device 211B.
The TCP Socket Server 605 makes the TNI-2 205 a TCP server. The TNI-2 205 listens for incoming connections from remote Ethernet devices 211A-211B.
The TCP/IP Subsystem 606 is the TCP/IP interface between the TNI-2 205 software and the operating system.
The Downstream Ethernet Interface 607 is the physical interface to the Ethernet Network 209. All downstream Ethernet devices 211A-211B initiate connections through this Downstream Ethernet Interface 607.
The Dynamic Host Configuration Protocol (DHCP) Server 609 is responsible for assigning dynamic TCP/IP addresses for the Downstream Ethernet Devices 211A-211B connected to the Downstream Ethernet Interface 607.
Optionally, the TNI-2 205 can contain an Internal Large Storage Device 611 for files that are required by downstream Ethernet devices 211A-211B. The File/Web Server 610 is responsible for sending these files to the appropriate downstream device requesting the file.
The Internal Large Storage Device 611 is usually a hard drive used to store files, but could be any data storage device.
The TNI-2 205 can optionally contain an Internal Wireless Ethernet Interface 608 for communicating with the downstream Ethernet devices 211A-211B.
The frame buffer then stores the video output that was created in the Internal Character Generator 701. Multiple Frame buffers exist because there can be multiple independent video output devices 704A-704B, each independent video output device 704A-704B displaying a unique display created from the Internal Character Generator 701.
The Hardware Video Card/USB 703A-703B is the physical interface between the Frame Buffer 702A-702B and the video output of the TNI-2 205.
The Video Output Device 704A-704B is how the image generated in the TNI-2 205 is displayed. The Video Output Device 704A-704B could be a monitor, television, or any other device capable of displaying a video output.
