Methods and systems for pairing a mobile device to an output device are disclosed. More particularly, methods and systems for enabling control of an output device by a mobile device are disclosed.
Televisions for providing audio-visual entertainment to guests are commonly available as part of hotel rooms. Often times televisions and other entertainment systems for use in the lodging industry are associated with distribution systems that permit guests to select from a variety of programming. This programming can include regular off-air television programs, pay per view movies, Internet access, and guest services such as video shopping and video checkout. In addition, hotel entertainment systems typically include a headend or property management server that is located within the lodging facility and that is linked to guest terminals in the individual guest rooms by a distribution system. The local client server generally controls the delivery of selected content to the room terminal, and the application of any associated charges to the room bill. In selecting content, the guest typically provides input using a remote control provided as part of the interactive equipment in the room. Similar systems can be deployed in hospitals or other facilities for the delivery of entertainment or other services to patient rooms.
Increasingly, mobile devices, such as mobile telephones or smart phones, are used as a primary interface with communication and entertainment systems. These interactive features are often accessed as or through applications or “apps” that are resident on the mobile device. Although apps can include applications that deliver audio-visual content to the user, the relatively small format of most mobile devices often provides a less than optimum user experience. Therefore, in a hospitality setting, it is desirable to make use of the entertainment equipment provided as part of a room's entertainment system. Although various wireline and wireless communication protocols are available that are capable of supporting communications between a mobile device and a room entertainment system, the hardware required to establish such links is often not a part of existing room entertainment equipment. In addition, simply connecting a user's mobile device to room entertainment devices has the effect of merely substituting a conventional remote control device for the mobile device, and does not itself enable any additional functionality.
Embodiments of the present invention are directed to solving these and other problems and disadvantages of the prior art. In accordance with embodiments of the present invention, systems and methods for associating or pairing a mobile device with an output device included as part of an interactive system are provided. More particularly, the mobile device is provided with a mobile application or mobile app, and is registered with a mobile connect server. In order to initiate pairing, the user enters a request for a pairing code via the interactive system or equipment. In response to the request, the mobile connect server returns a pairing code that is displayed or otherwise output to the user by the output device. The user then enters the pairing code in the mobile app on their mobile device. The mobile app returns the entered pairing code to the mobile connect server. In response to a match between the pairing code provided to the interactive equipment for output to the user and the pairing code entered in the user's mobile device and provided to the mobile connect server, the mobile device is paired to the interactive equipment. The user can then interface with their interactive equipment using the mobile device. In addition, the user can access personalized content, order other available content, and/or authorize payment for content or services.
A system in accordance with embodiments of the present invention can include a mobile device running a mobile application. The mobile device can be capable of operating as an endpoint of a communication link between the mobile device and the mobile connect server. Communications between the mobile device and the mobile connect server can be over various networks, such as a wireless carrier network, a wireline carrier network, a wireless or wireline local area network, and a wireless or wireline wide area network, including but not limited to the Internet. The mobile connect server is interconnected to a plurality of room interactive or entertainment systems that include terminal or output devices. This connection can be established over the Internet, and/or a proprietary network. In accordance with still other embodiments, a local client server can be interposed between the mobile connect server and at least some of the room output devices. As an example, a local client server can comprise a headend system that operates to provide selected programming to interconnected interactive or output devices at a hotel or other property having a number of output devices.
Methods in accordance with embodiments of the present invention include initiating a request for a pairing code for use in association with a selected terminal or output device. The request is sent to a mobile connect server, which responds with a pairing code. The returned pairing code is displayed or otherwise output to a user. The pairing code is then entered into a mobile application running on a user's mobile device. Entering the pairing code in the mobile application can include manual entry of the pairing code by the user in the mobile device. As another example, entering the pairing code can include scanning or photographing a representation of the pairing code comprising, for example a bar code or a quick response (QR) code. The mobile app in turn delivers the entered pairing code to the mobile connect server. Delivery of the pairing code to the mobile connect server can be accomplished using a communication link established between the mobile device and the mobile connect server. The communication link between the mobile device and the mobile connect server can include but is not limited to a carrier wireline or wireless network, a Wi-Fi or wireline Ethernet network, or combinations of network types and protocols. In response to receipt of a pairing code that matches the pairing code output by the terminal device, the mobile device is associated with or paired to the output device. In response to a valid pairing, various information can be displayed to the user by the mobile device, such as menus, channel guides, interactive program guides, and the like. Moreover, selections made by the user through the mobile device with respect to programming and/or other services can control operation of the output device.
Additional features and advantages of embodiments of the present invention will become more readily apparent from the following detailed description, particularly when taken together with the accompanying drawings.
The central server system 104 generally includes a mobile connect server 124. As described in greater detail elsewhere herein, the mobile connect server 124 operates as a central or control node in pairing a terminal or output device, hereinafter referred to as an output device 136 with a mobile device 112 and with enabling control of aspects of the operation of the output device 136 in response to input provided at the mobile device 112. Optionally, the central server system 104 can also include a data server 128. The data server 128 can provide various data and information to other components or nodes of the system 100, for example via the mobile connect server 124. Examples of such data include channel lists, TV program data and interactive program guide information.
The local client system 108 is typically associated with a physical location, or a group of related physical location, such as a lodging or healthcare facility. Thus, in one exemplary application, the local client system 108 can be associated with a hotel having any number of guest rooms. The local client system 108 generally includes a site or local client server 132. The local client server 132 generally functions as a headend for data and information provided by or in association with the central server system 104. Moreover, the local client server 132 connects the local client system 108 to the central server system 104. Although for ease of illustration a single local client system 108 is illustrated in
In addition to delivering content to an output device 136 and to handling input associated with requests for content, the local client server 132 can perform various administrative tasks. These administrative tasks can include associating charges, for example in connection with lodging, healthcare or other guest based services, for pay per view content or other content or services associated with specific charges to a room containing the output device 136 to which the content or service is delivered. In accordance with embodiments of the present invention, the local client network 140 can comprise an Internet protocol network, some other digital network, and/or an analog network.

In addition, an output device 136 can include an integrated terminal processor, a computer, and/or can be associated with a set top box or other separate component, to support two-way communications between the output device 136 and the local client server 132. Accordingly, the output device 136 can support the display of interactive menus and program guides, and the receipt of selections provided by a user or other user input that is relayed to the local client server 132. User input can be provided through keypads, touch screen displays, remote control devices or the like provided as part of the output device 136, for example as part of a set top box, game console, or television.
The mobile or user device 112 generally includes a device that is associated with a particular user 116. Examples of a mobile device 112 include a smart phone, tablet computer, laptop computer, or other mobile computing device. Moreover, the mobile device 112 generally supports execution of a mobile application, as described in greater detail elsewhere herein. Although for ease of illustration and description a single mobile device 112 and user 116 pair is illustrated in
The optional mobile application server 120 can handle various duties, such as the delivery or download of a mobile application to the mobile device 112 to facilitate interconnection and interoperability of the mobile device 112 with the remainder of the system 100. If provided, a mobile application server 120 can also handle registration of a particular mobile device 112 and/or user 116 with the system 100. Other operations that can be provided or supported by a mobile application server 120 include providing information concerning the programming or other amenities available at properties having compatible property management systems 108, for example in the vicinity of the mobile devices 112 current location, or at a location selected by the user 116. The mobile application server can also provide content for display on the mobile device 112, including audio-video content, such as promotional materials, advertisements, video on demand, or other content. Alternatively, such functionality and features can be provided by, for example, the mobile connect server 124.
In general, operation of the system 100 includes action by a user 116 to download a mobile application on their mobile device 112. Downloading the mobile application can be through establishing a connection between the mobile device 112 and a mobile application server 120 and/or a mobile connect server 124. Downloading can include registration with a mobile application server 120 and/or a mobile connect server 124. After installing and, if required by the particular implementation of the system 100, registering the mobile application, the user 116 has the option of pairing their mobile device 112 with an output device 136, to enable control of the output device 136 using the mobile device 112, where such control interaction involves commands entered in the mobile device 116 that are passed through and/or processed by the central server system 104.
With reference now to
A device 112, 124 or 132 can also include data storage 212. In accordance with embodiments of the present invention, data storage 212 can contain program code or instructions implementing various applications or functions executed by the associated device 112, 124 or 132. Like the memory 208, the data storage 212 can comprise a solid state memory device. In addition, in certain applications, the data storage 212 can be integrated with and/or indistinguishable from the memory 208, for instance on certain mobile devices 112. Alternatively or in addition, the data storage 212 may comprise a hard disk drive or other random access memory, and can be integral to the associated device 112, 124 or 132, or can be interconnected to the device, for example as network attached storage.
A device or node 112, 124 or 132 can also be associated with one or more user input devices 216. Examples of user input devices 216 can include keyboards, touch screen displays, position encoders such as a touchpad, mouse, or track ball, associated with a display, switches, or any other device capable of receiving input from a user 116. In addition, a device 112, 124 or 132 can be associated with one or more user output devices 220. Examples of user output devices 220 include displays, speakers, and indicator lamps.
In addition, each node 112, 124 or 132 can include one or more communication interfaces 224. The type of communication interface or interfaces 224 associated with a particular node 112, 124 or 132 is typically determined by the type of communication network 122 over which the associated node 112, 124 or 132 communicates. For example, in the case of a mobile device 112, a communication interface 224 can include an interface to a wireline or wireless carrier network, including but not limited to a cellular network, the public switched telephony network (PSTN), a satellite telephony network, or a wireline or wireless Internet protocol network. Moreover, different communication interfaces 224 can be used in different situations. For example, a mobile device 112 can include a relatively short range wireless communication interface 224, such as a Bluetooth or Wi-Fi network interface 224, for interfacing with an Internet protocol network 122. As another example, a mobile device 112 can include one or more relatively long range wireless communication interfaces 224, such as a cellular voice and/or data network or other wireless carrier network communication interface 224. Moreover, some or all of the available communication interfaces 224 can be used to interconnect a mobile device 112 including the communication interfaces 224 to a mobile connect server 124 or other node in the system 100. With respect to a mobile connect server 124 and/or a local client server 132, a communication interface 224 can include an Ethernet or other Internet protocol communication interface 224, for example for interconnecting to a network 122 comprising the Internet. As another example, a communication interface 224 associated with a mobile connect server 124 and/or a local client server 132 can include an interface to a proprietary satellite communication system. As can be appreciated by one of skill in the art after consideration of the present disclosure, different communication interfaces 224 can be used for different data and/or situations. For instance, a broadband communication interface 224 can interconnect a mobile connect server 124 to a telephony carrier's communication server for communicating with mobile devices 112 over a carrier wireless network. A broadband communication interface 224 to an Internet protocol network 122 connecting a mobile connect server 124 to one or more local client servers 132 can also be provided. As yet another example, a communication interface 224 that enables satellite communications between a mobile connect server 124 and one or more local client servers 132 can be provided.
Each node 112, 124 and 132 of a system 100 can be associated with different applications or application programming. These different applications can be stored in the data storage 212 of the associated node 112, 124 or 132. For instance, in the case of a mobile device 112, application programming can include a mobile app 228. As disclosed herein, the mobile app 228 can function to receive a pairing code that the mobile app 228 delivers to the mobile server system 124. In addition, the mobile app 228 can operate to display menus, channel guides, and interactive program guides or other information to a user 116, and to receive input from a user 116 that is relayed to the mobile connect server 124 for further action, such as to control the operation of a paired output device 136.
The mobile connect server 124 can store or maintain various applications and/or data in associated data storage 212. For example, global property data 232, including information received from interconnected local client servers 132 regarding programming available from particular local client servers 132 can be stored in data storage 212. As another example, mobile server data 236 can include information regarding registered mobile applications 228, and the current status of registered mobile apps 228. Mobile server data 236 can also include information identifying pairings between output devices 136 and mobile devices 112. As yet another example, mobile server data 236 can include channel guides, interactive program guides, movie schedules, TV show schedules, and the like in a format suitable for handling by a mobile app 228. Mobile server data 236 can additionally include output device 136 location information and/or location information for output devices 136 that have been paired to mobile devices 112. This location information can be stored as a latitude and longitude, an address of a property at which an output device 136 is located, and/or using other location identifying information. An example of an acceptable format of mobile server data 236 is an XML (extensible markup language) file. As another example, the data storage 212 of a mobile connect server 124 can include stored content 240. Stored content 240 can comprise generally available on demand content. As another example, stored content 240 can comprise content that is stored or recorded at the specific request of a user 116, for example for personal time shifting purposes. Accordingly, embodiments of the present invention can provide a virtual digital video recorder (DVR) service. As another example, the data storage 212 of the mobile connect server 124 can include a mobile server application 244. The mobile server application 244 can control various aspects and features of the functionality of the mobile connect server 124 with respect to interconnected mobile devices 112 and local client servers 132. For instance, the mobile server application 244 can respond to requests for pairing codes, and can associate a particular output device 136 with a particular mobile device 112 in response to receiving a pairing code from the mobile device 112 that matches the pairing code output by the output device 136. In addition, the mobile server application 244 can operate to receive commands input at the mobile device 112, and to control a paired output device 136 and/or cause content or other material to be delivered to an output device 136 and/or a mobile device 112 in response to such input. Other examples of programming and data that can be maintained in the data storage 212 of a mobile connect server 124 includes accounting data 248 that can track transactions and charges associated with a particular pairing and/or mobile device 112.
Examples of application programming and content that can be stored in the data storage 212 associated with a local client server 132 includes local property data 252. Local property data can include information regarding interconnected output devices 136, listings of stored and/or available content, location information related to the property or properties with which the local client server 132 is associated, and/or location information related to individual output devices 136 associated with the local client server 132. In addition, stored content 256, such as movies or other audio-visual content, can be maintained in the data storage 212. The data storage 212 of the local client server 132 also generally includes a local client server application 260. The local client server application 260 can handle interaction between the local client server 132 and the mobile or central server 124. In accordance with embodiments of the present invention, the local client server application 260 can also handle the delivery of pairing code information to an output device 136, and the delivery of content and/or control signals to connected output devices 136 in response to commands received from the mobile or central server 124. The data storage 212 of the local client server 132 can also include user stay information 264. Examples of user stay information 264 include records of transaction identifiers assigned to guests and associations of such transaction identifiers with one or more output devices 136, pairing codes, or subsequent identification codes.
With reference now to
At step 308, the user 116 enters a selection to pair an output device 136 with the user's mobile device 112. As an example, once opened, the mobile app 228 can instruct the user 116 to turn on the output device 136 (e.g., a television in a hotel room) push menu, and select mobile application from the menu. Selection of the mobile app 228 item from the menu displayed by the output device 136 can cause a request for a pairing code to be passed to the central server system 104. More particularly, the output device 136 can send a signal to the local client server 132, via the local client network 140. The local client server application 260 running on the local client server 132 associates the request with a transaction identifier, also referred to as a LodgeNet™ stay ID, that is assigned by the local client system 108 for use in tracking transactions related to a particular room and/or guest (i.e., user) 116. The local client server 132 can then pass the request to the mobile connect server 124 of the central server system 104 via a communication channel established using an interconnecting communication network 122 or a direct communication link.
In response to receiving a request to pair at the central server system 104, a pairing code is generated and returned to the local client system 108 (step 312). In particular, the mobile server application 244 can operate to generate a temporary code or pairing code that is associated with the transaction identifier provided with the request, and that is returned back to the local client server 132. The local client server 132 then operates to provide the pairing code to the output device 136 from which the request was initiated, via the property distribution network 140. In addition, the mobile server application 244 can cause a record to be created associating the pairing code and the transaction and identifier and that is stored as part of mobile server data 236. Notably, neither the local client system 108 nor the central server system 104 is required to have information regarding the identity of the user 116 or mobile device 112, at least at this point in the transaction. The output device 136 displays or otherwise outputs the pairing code to the user 116 (step 316). The pairing code can be displayed as a user friendly series of characters. As an example, and without limitation, the pairing code can comprise a six digit number. Alternatively or in addition, a pairing code can comprise a computer readable code, such as a barcode or a quick response (QR) code that can be captured by a camera or scanner provided as part of or in association with the mobile device 112. As yet another example, a camera included in the mobile device 112 can capture the pairing code and apply optical character recognition. At step 320, the pairing code is entered in the mobile device 112, and is sent to the central server system 104 via a communication network 122. Accordingly, entry of a pairing code can include manual entry of that pairing code by the user 116 into the mobile device 112 via a user input 216 provided as part of the mobile device 112. Alternatively, entry of the pairing code in the mobile device 112 can include the capture of a machine readable code through operation of a suitable capture facility provided by the mobile device 112 in response to commands entered by the user 116. Notably, the provision of a pairing code by the output device 136 that is entered or caused to be entered in a mobile device 112 by a user 116 is the only direct communication required between the output device 136 and the mobile device 112. Moreover, the pairing code can be transmitted from the mobile device 112 to the mobile connect server 124 of the central server system 104 using a network 122 that is separate from the network 122 interconnecting the central server system 104 to the local client system 108. Accordingly, a communication channel interconnecting the mobile device 112 to the mobile connect server 124 can be completely separate from a communication channel interconnecting the mobile connect server to the local client server 132 and/or the output device 136.
At step 324, a determination is made by the mobile connect server 124 as to whether a valid pairing code has been received. If a valid pairing code has not been received, the system can return to step 308, to wait for a further request to pair an output device 136 to a mobile device 112. If a valid pairing code is received, the mobile connect server 124 pairs the mobile device 112 from which the pairing code was received with the output device 136 that displayed the pairing code (step 328). A record of this pairing or association can be maintained in the mobile server data 236.
After a mobile device 112 has been paired to an output device or room terminal 136, the mobile device 112 can be used to control aspects of the operation of the output device 136. For example, the programming or other content or information displayed by the output device 136 can be controlled in response to input entered by the user 116 at the mobile device 112. In accordance with further embodiments, volume and other operating parameters of the output device 136 can be controlled through input entered at the mobile device 112.
The central server system 104 can continually monitor for input received from the mobile device 112, and in particular the mobile application 228 running on the mobile device 112 (step 332). Where input received from a paired mobile device 112 affects the output of the output device 136, for example in the form of a request to view a particular channel or item of content, the mobile connect server 124 can provide the requested content, for example a program from stored content 240 or an interactive program guide, from content stored on the central server system 104. Alternatively, the mobile connect server 124 can command the local client server 132 to stream content 256 stored by or in association with the local client server 132 to the output device 136, or to “tune” the output device 136 to a particular broadcast channel, etc. As yet another example, the input from the paired mobile device 112 can include input directing the output device 136 to output content provided by the mobile device 112 that is passed to the output device 136 through the mobile connect server 124 (step 336). After providing requested content or after determining that the input is not received from the mobile device 112, a determination can be made as to whether a new request to pair the mobile device 112 with an output device 136 is received (step 340). In general, a new request is received when a new pairing code is entered in the mobile application 228 of a mobile device 112, and where the new pairing code was generated in connection with a request from a new output device 136. In response to the receipt of a new pairing code from a previously paired mobile device 112, the original pairing can be terminated (step 344).
At step 348, a determination may be made as to whether a request to terminate pairing has been received by the mobile connect server 124. A request to terminate pairing can be initiated by a user 116 via the mobile app 228 running on the mobile device 112. A pairing can also be terminated when the user associated with a pairing checks out of or leaves the property at which the paired output device 136 is located. A request to terminate pairing can also be in the form of a request for a pairing code associated with the output device 136 that is also associated with a new transaction identifier. For example, a new transaction identifier can be used for a room that the output device 136 is associated with when the room is assigned to a new guest. As yet another example, termination of pairing can result from revocation of the transaction identifier associated with a pairing. If a request to terminate pairing is received, that previous pairing is terminated (step 344). The process may then end. So long as a condition resulting in the termination of an established pairing is not received, the process can continually check for input from a mobile device (step 332) and can provide content (step 336) as appropriate in response to received input.
In accordance with further embodiments of the present invention, pairing codes can expire after some predetermined period of time. In addition, the relatively short pairing code can be replaced by a longer pairing key that is exchanged automatically (i.e., without requiring manual entry or action by the user 116) after a successful pairing event, to enable the use of user friendly pairing codes, while providing an ability of the system 100 to service a large number of output device 136 and mobile device 112 pairings.
Although examples have been described in which a mobile device 112 is paired to a single output device 136, embodiments of the present invention can support simultaneous pairing of a mobile device 112 to multiple output devices 136. For example, with respect to a room or a suite having multiple televisions or other output devices 136, a mobile device 112 can be paired to those output devices 136 simultaneously. In accordance with still other embodiments, a pairing code output by a first output device 136 in a room or an associated room can be used to pair a mobile device 112 to a second output device 136 in the room or an associated room.
In response to a selection of the option to pair the mobile device 112 to a TV 424, the mobile app 428 can display a pairing screen 428. The pairing screen can provide instructions for completing pairing between the mobile device 112 and an output device 136. In addition, a field 432 can be provided in which a pairing code displayed to the user 116 by an output device 136 can be entered by the user 116. After the successful entry of a valid pairing code, additional features or options can be enabled. For example, in response to entry of a valid pairing code, the mobile device 112 can again display the initial or welcome screen 404, and certain options that were previously inactive, such as a browse movies option 408 is now active. Alternatively or in addition, additional categories or options can be presented.
In response to a selection of the browse movies item 416, movie listings 436 can be presented. The movies included in the movie listings are generally movies available from the local client server 132 associated with the output device 136 to which the mobile device 112 is paired. In response to a selection of the free mobile content option 412, a listing of mobile content 440 can include listings of content available for viewing on the mobile device 112. In response to the selection of the programming guide option 416, a programming guide page 444 can be presented to the user 116. The programming guide 444 generally contains programming that is accessible through the paired output device 136. The selection of the other services option 420 presents another services page 448 to the user 116. Examples of other services include content that has been recorded for personal time shifting purposes by the user 116. In connection with recorded material, the user 116 can order or otherwise arrange for the recording of selected content, for example through a request that is provided to the central server system 104. Moreover, such a request can be made via an interface provided by the mobile app 228. The interface for ordering the recording of specified content can be provided by the other services page 448. Moreover, that content can be ordered through the other services page 448. The recorded content can be maintained at the central server system 104, and can be delivered to the local client server 132 associated with the output device 136 to which the mobile device 112 is paired. Moreover, the delivery to the local client server 132 of recorded content can be initiated after the appropriate local client server 132 for delivery of the recorded content to the user 116 has been identified, for example in connection with a successful pairing operation, or in response to a request for that content, for example through a command entered using the mobile app 228.
In accordance with other embodiments, a mobile connect server 124 may comprise a server having a well known address that can be contacted by a mobile app 228. In accordance with further embodiments of the present invention, a mobile app 228 can establish communication with a local client server 132 directly, rather than through a mobile connect server 124. In accordance with still other embodiments, a mobile connect server 124 can communicate with output devices 136 without requiring an intervening local client server 132.
In accordance with embodiments of the present invention and as described herein, information regarding the location of a mobile device 112 and/or an output device 136 paired to a mobile device 112 can be used to provide relevant information to a user. For example, a set of movie listings 436 and/or a programming guide 444 can be tailored to include only those listing available at the current location of the mobile device 112 and/or the location of the property including the output device 136 with which the mobile device 112 is paired. In addition, the location of a mobile device 112 can be used to provide that mobile device 112 with other services 448 that require or that can benefit from the location information. In accordance with embodiments of the present invention, the location of the mobile device 112 can be determined based on the pairing of the mobile device 112 with an output device 136. In particular, embodiments of the present invention include a mobile server application 244 that has or can access the location of an output device 136 paired with a mobile device 112. From the location of the output device 136, the location of the mobile device 112 can be inferred, even if the user of the mobile device has disabled conventional location services or has otherwise declined to provide location information. In accordance with still other embodiments, the location information derived from the location of a paired output device 136 can be provided to the mobile app 228 running on or associated with the mobile device 112 paired with that output device 136. The mobile app 228 can then use the location information in connection with location based services, even if the user of the mobile device 112 has disabled other location services.
