Patent Application
20210046389
This patent document relates to interactive gaming environments. Interactive gaming environments can include multiple users interacting with a main controller. The multiple users can be dispersed across multiple locations. Examples of interactive games include games that interact with video feeds from a football, question-and-answer games, or trivia. The response time of a user's input into the interactive gaming environment can be compared to the other users' response times.
Interactive gaming environments can be provided over various communication pathways such as computer networks, e.g., Internet, wireless networks, or television signal distribution architectures. Television signal distribution architectures have been developed to provide alternatives to traditional over-the-air broadcasting. For example, since the late 1940's, cable television systems have been used to deliver television signals to subscribers. Cable television systems distribute signals over optical fibers and/or electrical cables, such as coaxial cable. Further, wireless-cable systems have been developed using microwave signals as the distribution medium. Cable television systems permit the distribution of both typical over-the-air content, such as broadcast networks, and specialized content, such as pay channels and video on demand.
In a cable television system, television programming representing a number of individual television channels is coordinated at a headend for distribution to subscribers, such as endpoints within a particular geographic region. All of the endpoints serviced by a headend receive a common signal. Television programming representing a plurality of separate frequency bands is multiplexed onto a single cable. The television signal can be encoded as an analog signal or a digital signal. A set-top box (or “cable television tuner”) at the receiving location, such as a subscriber's home or business, provides access to a single channel of the multiplexed signal. Thus, a single channel included in the cable television signal can be tuned and presented on a corresponding device, such as a television or computer monitor.
Direct broadcast satellite television systems also have been developed as an alternative to over-the-air broadcasting. As with cable television, direct broadcast satellite television provides a single, multiplexed signal that is decoded using a set-top box (or “satellite receiver”). The distribution medium between the satellite broadcaster and the set-top box, however, is a radio frequency signal, such as a Ku-band transmission.
Until recently, both cable and satellite television distribution systems were limited to receive-only. Because coaxial cables are capable of bi-directional transmission, however, additional services have been merged with cable television systems. For example, voice and data services have been offered over cable television distribution systems. Similarly, the cable television transmission path can serve as a back-channel for information sent from the set-top box to the cable television provider. Typically the bandwidth upstream from a set-top box to a headend is lower than the downstream bandwidth from the headend to the set-top box. Further, satellite television providers also have implemented bi-directional communication capabilities and are offering additional services, such as internet connectivity, in conjunction with the television signal distribution architecture.

Like reference symbols and designations in the various drawings indicate like elements.
This document describes, among other things, techniques and systems that allow game players to use their mobile devices, such as a mobile phone or a tablet computer, to participate in interactive gaming environments. A mobile device can run a mobile playmaker application that provides access to a gaming network. The gaming network provides connectivity to site servers running gaming instances at respective gaming locations. Further, the gaming network provides a communication pathway between mobile devices and site servers. In some cases, game play can be coordinated between multiple locations via the gaming network.
Game players, such as those without mobile phones that are capable of running the mobile playmaker application, can access the gaming network via controllers that reside at a gaming location. The controllers are connected with a site server associated with the gaming location. A game player, for example, can be matched up and play games against other players that are associated with the same gaming location regardless of how they are accessing the gaming network (e.g., accessing the gaming network by a mobile device or accessing the gaming network by a controller).
Participants of an interactive gaming environment can be located in multiple locations or in a single location. Gaming locations can include public locations such as bars, restaurants, and in general, gaming establishments. These gaming locations can be associated with separate gaming instances. For example, a trivia gaming instance at Joe's Bar is separate from a trivia gaming instance at Jim's Traven. In some cases, however, a gaming instance can be associated with more than one gaming location. For example, participants at Joe's Bar join with the participants at Jim's Traven to play a trivia game.
Interactive gaming environments can include displaying game information at one or more locations. Game information can be synchronized with live feed video.
For example, the QBI game, available from NTN Buzztime of Carlsbad, Calif., can synchronize a gaming environment with a real-time video feed of a football game. Other games can include question-and-answer games such as trivia games. In each of these games, a user at some remote location plays in the game. The game can be played either by itself or can be scored against one or more other players who are playing the game at the same time.
Gaming establishments can provide playmakers so that users can play the game. However, such playmaker devices can be relatively expensive and can be a barrier to entry for many gaming establishments. Thus, it is advantageous for an interactive gaming environment to interface with a user's own mobile device. For example, multiple access points can be used to allow access to a game server to enable the use of a user's own mobile device. Multiple types of devices, including wireless and wired, can be used to interact with the game server. The devices can include mobile phones, personal data assistants, wireless playmaker devices, or wireless tablet computers.
Interactive gaming environments can be of a time sensitive nature. For example, game scoring can include determining when a user made a response, e.g., pushed the “send” button, to a game event and comparing that time with response times of other users. Time sensitive gaming environments can require game information to be displayed on a playmaker within specific time frames. A game event, for example, can include a question presented to players of the game, or sport players preparing to start a play. Timing can be an important element when scoring game responses.
Time sensitive gaming environments can require a user to make a response at a specified time or before a specified time. For example, a sports-based game can be played in sync with a real-life game such as football. In one such sports-based game, the users can attempt to guess the play that will be made by the team at the next play time. A game response can include a type of play. As the offense approaches the line of scrimmage, the players can guess the contents of the play. For example, a user can make a guess based on the way the offense approaches, body language, line up positions, etc. Game responses can be locked out before the play starts to avoid any game player receiving an unfair advantage. However, it can be advantageous to allow players to see the sport's players up to the last second, at the line of scrimmage, so that the game players can make the best guesses. The user with the most correct guesses wins the game. Therefore, such a sports based game can attempt to synchronize with the football “snap” to allow game responses up until the moment of the snap. In another example, in a question-and-answer game, a user can receive more points when answering the questions sooner, and/or can receive hints at different times. Therefore, compensating for latency can be important for such time sensitive games.
In an interactive gaming environment where game responses are received from multiple disparate physical networks, the different latencies between the disparate networks to the game server can become an issue. These disparate networks can include local area wireless networks, such as those based on IEEE 802.11 standards, wide area wireless networks, and cellular networks by multiple service providers. In addition, the mode of communication within these disparate sources can include IP-based packets and text messages using a protocol such as Short Message Service (SMS). Further, poor signal strength in a wireless network can increase the latency of an individual mobile device used in the network. Latency can vary greatly between these disparate networks. Such variations in latency can impact the scoring of a game if the timing of the receipt of the game response at the main controller is used to determine when a user made the game response.
Interactive gaming environments can include one or more server systems. A server system can include one or more servers such as a game server that coordinates game play. In some implementations, a game server can control a site server to coordinate game play at a gaming location. A server system can include one or more remote processing units (e.g. set-top box or other embedded systems, programmed general purpose computers) that act together with the game server or independently.
A gaming server system 104 can contain, receive, integrate and execute video data, game data, and game applications. In some implementations, a gaming server system 104 includes a game server 115 that runs gaming related processes. In some implementations, a gaming server system 104 can include one or more servers such as headend servers or headend collocated servers. A web server 110, included in the gaming server system 104, can be configured to match a mobile device's 101 physical location to a gaming location associated with a site server 105. For example, the mobile device 101 can send the web server 110 a request for information about any gaming instances at a gaming location that is in proximity with a phone's physical location. The web server 110 can identify a gaming instance and can send information on how to communicate with the gaming instance to the mobile device 101.
A game control application, running on a mobile device 101, can encode and send a mobile device's physical location to a gaming server system 104 via one or more networks 103. In some implementations, a game control application causes a mobile device 101 to determine geographical coordinates of the mobile device 101 based on receiving signals from one or more satellites in a global positioning system (GPS). In some implementations, a mobile device 101 can send GPS signals to a server which determines the geographical coordinates and sends the geographical coordinates to the mobile device 101.
In some implementations, a game control application can retrieve, from a mobile device 101 communication process, one or more identifiers of base stations in a wireless communication system that is serving the mobile device 101. The game control application can send information such as one or more base station identifiers to the gaming server system 104. The gaming server system 104 can determine an approximate physical location of the mobile device 101 based on the base station identifiers. In some implementations, a gaming server system 104 can determine an approximate area of a mobile device 101 based on a network address, such as an IP address, associated with the mobile device 101.
A game server 115 of a gaming server system 104 can run one or more game applications that build and run game contests among players. The game server 115 can provide communication between different local game experiences that are created by site servers 105. A player can be connected via his mobile device 101 to a site server 105 to play a game. Alternatively, a player can be connected via a local controller 107 to play the game. A local controller 107 can be connected to a site server 105 via a local wireless connection or wired connection. In some implementations, a mobile playmaker application, running on a mobile device 101, can request a list of game sites that are associated with a mobile device's physical location. A gaming server system can send gaming information to the mobile playmaker application. Gaming information can include a game instance identifier and a network address of a proxy for communicating with a corresponding game instance.
A video feed can include one or more advertisements. A game control application can switch from an interactive game mode to a video display mode. In a video display mode, the game control application can receive a video feed from the video server and synchronize a display of the video feed on the mobile device to a display of the video feed at a monitor located in a gaming establishment where the device is currently located. Once a play of the advertisement is finished, the mobile device can switch to an interactive game mode.
In some implementations, a wireless capability 331 can communicate directly with a user's personal mobile device 335. For example, the mobile device 335 can be a cell phone, Blackberry, or PDA. The mobile device 335 can include a WiFi module. The WiFi module can transmit and receive signals in accordance with a protocol such as the IEEE 802.11 family of protocols. The mobile device 335 can search for wireless signals and connect to other mobile devices. The WiFi module of the mobile device 335 can communicate with the RPU 325 over a wireless link, when the mobile device 335 is in range of the wireless capability 331 of the RPU 325.
In some implementations, a mobile phone 340 can be used in a cellular network to communicate directly with the main controller 300. The mobile phone 340 can use resources of a cellular network, such as a wireless communication tower 341 via a wireless link, to communicate with the main controller 300. The cellular network can use a communication path 307 to establish a connection between the tower 341 and the main controller 300. The communication path can include private networks of the cellular network provider and the Internet.
The mobile device 340 can use software such as a native web browser or a custom downloadable program to enable communications with main controller 300. The software can render game stimuli and capture game responses. The program can be written in C, C++, Java, BREW (R), or any other programming language. For example, the program can be written in the device's operating system and can allow direct communication to the main controller 300. The communication can be over regular cellular airwaves or over Short Message Service (SMS).
Another device, such as a mobile phone 350, can use a different wireless network to communication with the main controller 300. The mobile phone 350 can use resources of a wireless network, such as a wireless communication tower 351 via a wireless link, to communicate with the main controller 300. The wireless network can use a communication path 306 to establish a connection between the tower 351 and the main controller 300.
A mobile device 336 can include a Bluetooth™ wireless module 337. In some implementations, the wireless capability 331 of the RPU 325 can include Bluetooth™ capabilities. Therefore, the mobile device 336 can communicate with the wireless capability 331 of the RPU 325 via the Bluetooth™ wireless module 337.\
The mobile device 336 can use software such as a native web browser or a custom downloadable program to enable communications with the RPU 325. The software can capture game responses such as a user pressing a button on the mobile device 336. The software can send the response to the RPU 325. In turn, the RPU 325 can process the game response and/or forward the response to the main controller 300.
The latencies between mobile devices 335, 336, 340, 350 and the main controller 300 can vary. Further, latency can vary widely between different cellular networks and wireless networks. In order to compensate for the varying latencies, a mobile device 335, 336, 340, 350 can send, in addition to the game response, a timestamp indicative of the time when the game response was made. For example, a device can capture the time when a user presses a button that generates the game response. The main controller 300 can receive a response from a mobile device at some later time, perhaps as long as 2 to 15 seconds later. The main controller 360 can look at the timestamp in the response, rather than looking at the response's actual received time. In this way, the latency in the network can be compensated in non-real time.
In some implementations, a mobile device can be a laptop computer. Some implementations can distribute the functional components of the main controller amongst other gaming components such as a RPU. Other implementations can include multiple RPUs. Alternatively, an implementation can include a main controller and mobile devices without the use of a RPU.
A mobile device 420, which can be referred to as a mobile playmaker, can communicate with the geolocation web server 405 to retrieve information about one or more gaming instances. In some implementations, the mobile device 420 transmits geographical coordinates to the geolocation web server 405, and the geolocation web server 405 identifies one or more gaming locations based on a proximity with the mobile device 420.
The mobile device 420 can communicate with a selected gaming instance via the multiplayer server 410. The multiplayer server 410 can provide a duplex connection between the mobile device 420 and a site server 415. Providing a duplex connection can include routing gaming messages between the mobile device 420 and at least one of the site servers 415. The site server 415 can provide gaming video output to respective monitors 430, 435.
A system for game play, in some implementations, can include two or more site servers; a gaming server system that is configured to contain, receive, integrate and execute video data, game data and game application; and a mobile device running a game control application which encodes and sends the mobile device's physical location to the gaming server system. In some implementations, a gaming server system is capable of matching a mobile device's physical location to at least one of the two or more site servers. In some implementations, the gaming server system is configured to run one or more game applications that build and run game contests among players connected via respective mobile devices in a given physical location and players connected via a site server at the same physical location. In some implementations, the gaming server system includes a video server to provide a video feed.
In some implementations, a system for game play can include a television distribution system. For example, an interactive gaming service involving one or more subscribers (or players/users) can be provided over a television distribution system. Game play can be initiated from a client device, such as a mobile device or a set-top box included in the television distribution system. Further, execution and coordination of a game instance can be controlled by a server system included in the television distribution system. For example, the server system can be configured to control access to a game, to manage game play, to record game scores, and to facilitate communication and interaction between subscribers participating in one or more game instances. Other interactive services also can be provided such as shopping, weather forecasts, and chatting.

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for performing actions in accordance with instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), to name just a few.

Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks). The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In some embodiments, a server transmits data (e.g., an HTML page) to a client device (e.g., for purposes of displaying data to and receiving user input from a user interacting with the client device). Data generated at the client device (e.g., a result of the user interaction) can be received from the client device at the server.
