Devices such as televisions may be shipped with a remote control device which may be a classic hand held remote control device or a mobile smart remote or multiple remote control devices some of which may have display screens and physical or virtual keyboards.
Many televisions capable of being connected to the internet have user interfaces which among other features allow the user to setup wireless options for WiFi. Locating WiFi routers that broadcast their SSID in the clear can be confusing to the average user, especially when the television is located in an environment such as a residential area where multiple residences contain at least one Wifi Router or multiple residences may contain routers with the same SSID name.
This is even more difficult for Wifi Routers that do not broadcast their ID. This scenario requires entering long strings of SSID names or MAC addresses or filling out a form that identifies a WiFi Router. This is even more difficult when using a television based user interface. Other devices such as DVD players and other devices lacking display screens or very limited display screens but with Wifi capability are equally challenging to connect to a wireless router.
The inventor recognized the need for some way to simplify the process of setting up a wireless link between a router and a television.
Another need recognized is for a connection between multiple televisions and a single router.
A simplified way of connecting electronic devices with limited user input capabilities to wireless network routers is disclosed such as a DVD player, Television, microwave oven, etc. A smart device with a user interface and input capabilities is first connected to a Wifi router and has programming to remember the Wifi variables used for the connection. That smart device is then paired with the electronic device and transfers the Wifi connection variables to the electronic device.
The smart device has a user interface, and a first software program. The smart device, such as a tablet computer, laptop, or smart phone with the first software program has a user interface that facilitates the user initially connecting with a local Wifi router. The connection variables used during the connection process are saved by the smart device. The user may then connect the smart device to the electronic device via a paired communications link and the connection variables for the router are passed over the link. The electronic device executes a second software module to connect to the router using the connection variables it received from the smart device.

Embodiments describe a smart remote which may be paired with a television at the factory or may pair automatically when both devices are initially powered on and placed in close proximately to each other. The smart remote may be based on a tablet computer, smart cell phone, PDA, or a purpose built smart remote.
For the present application, it will be assumed that the smart remote will be a hand held tablet computer. The smart remote controls at least one function of the remote device (Television), for example the on-off function, for a television and the channel changing, and for other devices such as ovens and garage doors, controls the their appropriate operations. The tablet user interface being executed on a touch sensitive device allows for a richer experience. In this environment, the user can be presented with a list of discovered Wifi Routers and their names. This functionality allows the user to more easily identify the Wifi Router or to enter the name of a router that does not broadcast its SSID and to enter a password and/or the MAC address of the client device.
Once the Wifi Router is identified, selected, and a password entered, the tablet remote control device can setup the Wifi wireless link between its paired television and the Wifi by passing the credentials for access across a secure link or to the television or on an out of band link. In the event a Wifi wireless enabled handheld remote control device is included with the television, the tablet can pass the Wifi credentials to that device as well.
An embodiment describes operation using Bluetooth, however it should be understood that other formats can be used.
Bluetooth devices may pair with multiple other devices and as such, provisions are made for a tablet remote control device being able to populate Wifi credentials across multiple other devices (televisions, DVD players, Tuners, Home Theater Systems, Game Controllers, Microwave Ovens, etc.) that the tablet is paired with.
In a preferred embodiment, a smart device, such as a desk top computer, tablet computer, smart phone, smart mobile remote, or a PDA has a user interface that has advanced functions (e.g., keyboard and/or touchscreen). This smart device is paired with an electronic device having limited user interface capabilities (such as a television, DVR, microwave ovens, refrigerators, heaters, and other consumer electronic devices). The smart device, e.g. a tablet, will then be connected with a local wireless router. Once the connection process with the wireless router is completed, the tablet transmits the connection variables that will allow the limited capability device to communicate with the wireless router over the paired link.
More generally, the smart device can be any device that has either a full keyboard or a soft keyboard displayed on a touchscreen, and the electronic device having limited user interface capabilities required entry of the information either on a remote control that enters data using arrows to select between options, or using an on-device user interface that again requires the use of navigation arrows.
In a related embodiment, the smart device may be paired with multiple electronic devices either before or after the smart device has been connected to a wireless router. In this embodiment, the smart device can be directed by the user to transmit the connection variables to more than one electronic device over any of the paired links and the connection variables that will allow the electronic device to be linked to the wireless router will be transmitted to the electronic device(s).

In this high level depiction, television 14 and smart remote 16 will, when they are first powered on, enter a pairing mode. The pairing mode will be initiated by the user and will allow the two devices to recognize each other and to enable a secure communications link between them. For clarity, secure connection 20 between television 14 and smart remote 16 will be assumed to be Bluetooth. In this scenario, smart remote 16 will be the Master and television 14 will be the Slave. The Master device (smart remote 16) will initiate the connection with the Slave (television 14).
After the pairing mode has completed, smart remote 16 searches for a Wifi AP such as Wifi AP 12. Smart remote 16 then operates, after inventorying the Wifi APs that it can “see”, to display a list of Wifi APs to the user. The user selects one of the Wifi APs and smart remote 16 asks for the password for the selected Wifi AP. The user enters the password for the selected Wifi access point and smart remote 16 attempts to connect to the selected Wifi AP. If the connection attempt times out before the connection is made or the password is rejected by Wifi AP 12, smart remote 16 assumes that the password entered by the user was incorrect and will notify the user that the password was not recognized by the selected Wifi AP. The process then returns to displaying a list of Wifi APs to the user and the user will have the opportunity to reselect a Wifi AP and to enter a password. If the connection attempt is successful, smart remote 16 will send a message to television 14 to launch an application that will attempt to connect to the same Wifi AP that smart remote 16 is currently connected to.
When smart remote 16 sends the message to television 14 to launch the connection application, the connection variables or credentials necessary for the connection to take place are sent as signal 50 (

Smart remote 16 is initially powered on at processing block 28 smart remote initial power on. After being powered on, control falls through to processing block 30 pair with television. In this embodiment, smart remote 16 is designated as a Bluetooth Master. Processing block 30 pair with television and processing block 34 pair with smart remote complete the pairing process for which ever secure protocol is being used for communications link 20 which in this embodiment is Bluetooth.
After communications link 20 has been established between television 14 and smart remote 16, control falls through to call function processing block 36 call function: connect to Wifi AP. This processing block calls the function depicted in
Processing block 36 waits for the called function to return with a return status. After the function has returned to processing block 36, control falls through to decision block 38 connected to Wifi AP? If the return status from the function was “not connected”, control will transfer to result processing block 40 NO after which control will fall through to display processing block 42 display: not connected to Wifi AP which informs the user that the connection process failed. Control then falls through to terminate processing block 44 terminate session.
If the return status from the function was “connected”, control will transfer to result processing block 46 YES after which control will fall through to display processing block 48 launch connection application. This processing bock sends a “launch application” (connection variables 50) request to television 14 over communications link 20. The launch application request to television 14 will be sent via signal 50 connection variables to television 14 processing block 52 attempt to connect to Wifi AP. This processing block will receive connection variables 50 including the SSID of the Wifi AP and the password, if any, used by remote control device 16 to gain access to the targeted Wifi AP. This process block will contact Wifi AP 12 using the provided SSID and if prompted by Wifi AP 12 for the password it will send the password after which control will fall through to decision processing block 54 connected to Wifi AP? The decision processing block waits for a predetermined period of time for an acknowledgement from Wifi AP 12 that television 14 is connected or that the password was rejected or the connection request timed out. If the password was rejected or the connection request timed out, control is transferred to results processing block 56 NO after which control will fall through to display processing block 58 display: not connected to Wifi AP after which control will fall through to processing block 60 terminate session. If decision processing block 54 received an acknowledgement of “connected” control is transferred to results processing block 62 YES after which control will fall through to display processing block display: connected to Wifi AP.
At this point, both television 14 and smart remote 16 are both connected to Wifi AP 12 and to each other via secure communications link 20.

If the user response at user response block 80 was yes, then query processing block 76 would have transferred control to results processing block 94 YES after which control will fall through to processing block 96 search for Wifi AP. This processing block listens on all of the Wifi channels for Wifi access points (AP) that broadcast their Service Set Identifier (SSID) which is a 32-character string (the characters can be anything a computer can type, such as a letter, number, symbol, punctuation mark, and even a blank space). A wireless network can be either hidden or visible. If the SSID is broadcast (visible), then anyone can find that network access point and connect if they have the password.
Once processing block search for Wifi AP 96 has collected the SSIDs of all broadcasting Wifi Aps, control falls through to processing block 98 display list of Wifi APs to user. This processing block displays an ordered list of Wifi APs along with their SSIDs. The user is prompted to select one of the Wifi APs after which control will fall through to processing block 100 wait for user to pick Wifi AP.
This processing block waits until the user selects one of the Wifi APs listed in the displayed list; after which control will fall through to processing block 102 ask user for Wifi password. At this point, control will fall through to processing block 104 request Wifi AP to connect. This processing block will contact targeted Wifi AP 12 using the provided SSID for targeted Wifi AP 12. Targeted Wifi AP 12 will, if it is secured with encryption, request a password. Control will at this point fall through to processing block 106 send PW to Wifi AP.
This processing block sends the user entered password to Wifi access point 12 after which control will fall through to decision processing block 108 connected with Wifi AP?.
This decision block waits for a predetermined period of time for Wifi AP 12 to respond to the connection request. If Wifi AP 12 responds within the predetermined period of time verifying the connection, control transfers to results processing block 110 YES after which control falls through to return processing block 112 return: connected. This processing block returns to the caller with a return status of “connected”.
Similar operations can be carried out, for example, to connect the tablet to the access point using an automatic, e.g. button connection such as WPS, and then to transfer that WPS-obtained connection to the television. In the case of WPS, the password is received wirelessly, where the term password refers to any kind of connection variable received as part of the automatic connection. If the automatic connection is MAC ID's sensitive, that is the automatic connection made from the tablet would not work on the electronic device, then the tablet can be used to initiate the automatic connection with the television so that the automatic connection is creating with and using the MAC ID of the television.
If decision processing block 108 determines that the response from connected request was rejected or timed out, control is transferred to results processing block 114 NO after which control falls through to return processing block 116 return: not connected. This processing block will return to the caller with a return status of “not connected”.

First scenario, smart remote 16 communicates with each television regardless of where televisions 14 and 15 are placed and the location of smart remote 16. Smart remote in this instance of the invention has a television selection application which allows the user to quickly select which television (14 or 15) smart remote 16 will control. The connection can be via Wi-Fi, or the like, so that the smart remote can control any television that has network access.
Second scenario, as smart remote 16 moves away from one television the paired secure communications link (20 or 21) stops and as the user approaches the physical location of the other television, the paired communications link for that television connects and communications are established. In this scenario, the user does not need to manually select which television (14 or 15) to communicate with.
Other embodiments are possible.
The present application has described use with only a few different kinds of formats, such as Bluetooth, but it should be understood that other formats can be used. The disclosed device and techniques could be used with any control device and any controlling device.
The system describes connecting with a network device, wirelessly Wi-Fi access point, however it should be understood that this can also use WPS to make the connection, and then transfer the credentials from the connection to the television.
The above has described special program as running in both the television and the tablet. However, a program such as an app can run in the tablet, and carry out all operations which are necessary to connect to the access point, and then use one or more techniques to communicate with the existing user interface in the television, that is without running a special program and the television. For example, this can send remote control commands to the television via Bluetooth, Wi-Fi, or via infrared commands. Once the tablet has been connected with the access point, the tablet can run a simulation program that simulates the actions that the user might carry out on an infrared remote, thus sending all the necessary infrared codes to the television, without the user needing to enter those codes.
The number of televisions that can be controlled with the smart remote is larger than two which is used in
Any consumer device with Wifi capability may benefit from the disclosed invention. These can include microwave ovens, normal kitchen ovens, refrigerators, household air conditioning and heating systems, home theater sound systems, security devices such as lights and opening sensors, swimming pool heaters and pumps, etc.
