     FIELD 
     The present disclosure relates generally to video calling. More particularly, the present disclosure relates to the use of ancillary devices with video call devices in video calls. 
     BACKGROUND 
     Most conventional remote control devices for video call devices rely on a simple infrared remote communication device with fixed buttons and a static layout of controls. Such remote control devices are designed in such a way that they can communicate with any and all identical destination devices simultaneously. This is accomplished by broadcasting a one-way stream of data from the remote to any listening devices. 
     A conventional video call device normally consists of one or two video monitors, a video camera, an optional document camera, a microphone array, and an infrared (IR) remote control device. Most video call devices utilize a simple infrared remote control device. Since these remote control devices transmit button presses as broadcasts to all listening devices, they are unable to target specific video call devices to control, and also are unable to receive feedback from the video call devices. 
     Most modern remote control devices do not provide reconfigurable screens that are dictated by the controlled device. This means that even though a remote control device can reconfigure its display or the underlying value for each of its buttons, this reconfiguration is driven by the remote control device itself, and not by the controlled device. The reason for this is the simple one-way communication that most remote control devices have with their controlled device. 
     Applications that have been written for mobile electronic devices such as smart phones to replace dedicated remote control devices tend to function almost identically to the remote control devices they were meant to replace. Such applications broadcast one-way data streams from the remote control device to the controlled device, providing simple button presses that represent the buttons that would have been pressed on a dedicated remote control device. Because these simple applications are merely replacements of existing remote control devices, they tend not to take advantage of other resources that are available on the mobile electronic devices. 
     Current video calling solutions generally require that the cameras and microphones used during the video call be managed by the local video call device. Therefore, alternate camera feeds and audio sources can not easily be added and removed from a video call. Video call devices usually have a fixed number of cameras and microphones for use during a video call. With a static number of cameras available it can be very challenging to coordinate a collaboration session where camera and microphone placement may need to change, or the passing of control of the media streams is needed.

       FIG. 3  shows elements of a smart remote control device  300  according to one embodiment. Although in the described embodiments the elements of the smart remote control device  300  are presented in one arrangement, other embodiments may feature other arrangements. For example, elements of the smart remote control device  300  can be implemented in hardware, software, or combinations thereof. For example, the smart remote control device  300  can be implemented as smartphones, tablets, general purpose computers, specialized devices, and the like. The smart remote control device  300  can be used in place of the remote control device  110  to control the video calling device  102 A of  FIG. 1 . 
     Referring to  FIG. 3 , the smart remote control device  300  includes a processor or central processing unit (CPU)  302 , a memory  304 , a camera  306 , a speaker  308 , a microphone  310 , and a user interface  312 , which can include touch screens, trackballs, rocker switches, buttons, and the like.

In some embodiments, wireless network adapter  314  is compliant with all or part of IEEE standard 802.11, including draft and approved amendments such as 802.11-1997, 802.11a, 802.11b, 802.11g, 802.11-2007, 802.11n, 802.11-2012, and 802.11ac. 
     Beaconing for Simplified Pairing with Video Call Devices 
     By leveraging networking and sensor arrays, the disclosed smart remote control devices  300  can intelligently detect the most logical video call devices  102  to pair with at start up. The user is also allowed to override the default choice, and can choose the particular video call device  102  to pair with the smart remote control device  300 . Beaconing is used to automatically detect the best video call devices  102  to pair with. If the user of the smart remote control device  300  is in a situation where a more ideal video call device  102  is detected, for example if the user walks into a different room with a different video call device  102 , then the smart remote control device  300  will allow the user to re-pair with the new video call device  102 . This allows for a single smart remote control device  300  to fluidly flow between many video call devices  102  and video calls. 
     The disclosed smart remote control devices  300  can use their onboard sensors and communication devices alone or in any combination to detect video call devices  102  to pair with. The smart remote control devices  300  can employ a best effort approach to select a video call device  102  for pairing. For example, a smart remote control device  300  can send network broadcasts and receive responses from the video call devices  102  to identify all available video call devices  102 . If the smart remote control device  300  receives multiple responses, the smart remote control device  300  can command the video call devices  102  to transmit further information. For example, if the video call devices  102  include a piezoelectronic device as a ringer, the smart remote control device  300  can command the video call devices  102  to transmit ultrasonic signals, and can measure the signal strength of the signals to identify the closest video call device  102 . Other examples include the use of signals including Bluetooth signals, near field communication (NFC) signals, infrared pulses, GPS, human-audible pulses, and the like. In addition, several smart remote control devices  300  can pair with a single video call device  102 . 
     Stateful Remote Control of Video Call Devices 
     The disclosed smart remote control devices  300  enable stateful control of video call devices  102  including visual feedback and multiple input modes (including touch screen, gestures, virtual keyboard, virtual mouse, voice recognition and the like). The described smart remote control devices  300  also provide dynamic instrumentation screens. The video call device  102  provides contextual information to the smart remote control device  300  about the current state of the video call device  102 . The smart remote control device  300  uses this feedback stream to modify the user&#39;s experience by reconfiguring the screen and available options of the smart remote control device  300  to show only the most relevant choices. The display format may change based on the type of data to be input, such as a text string, a number, or a graphical list of contacts, etc. The display may also change based on the current mode of the system. For example, if the video call device  102  is currently in a call, the video and audio streams can be rendered on the smart remote control device  300  as well. 
     The smart remote control device  300  software can be updated based on the version of the paired video call device  102 . So if a smart remote control device  300  pairs with an older video call device  102 , the smart remote control device  300  can automatically configure its software to the version of the video call device  102  to remain compatible with all versions of the video call devices  102  even in a heterogeneous video conferencing environment. 
       FIGS. 4-8  show displays shown by a smart remote control device  300  for five different states according to one embodiment. Of course, other states are contemplated.

To the right of the touchpad  410  are a mouse button  414  and a gears button  416 . The mouse button  414  toggles a virtual mouse state. In the virtual mouse state, gestures on the touchpad  410  control a mouse cursor on the display device connected to the video call device  102  being controlled by the smart remote control device  300 . The gears button  416  changes the state of the smart remote control device  300  to a connection state where a user can choose the video call device  102  to be controlled by the smart remote control device  300 . 
     Above the touchpad  410  are a menu button  418 , a home button  420 , a keyboard button  422 , and a hang-up/back button  424 . The menu button  418  changes the state of the smart remote control device  300  to a menu state where a menu of options is displayed. The home button  420  changes the state of the smart remote control device  300  to a home state where a home screen is displayed. The keyboard button  422  toggles an on-screen keyboard state. The hang-up/back button  424  can be used to end a video call or to return to a previous state. 
       FIG. 5  shows a display  500  for an active video call devices state.

Each video call device  102  can be assigned a name. The video call devices  102  are listed by name at  502 . At  504 , next to each name is a button for calling or disconnecting the respective video call device  102 . The appearance of each button  504  indicates whether the video call device  102  is part of the current video call. For example, the button next to the video call device name “Engineering” is cross-hatched, indicating that video call device  102  is part of the current video call. If the list is too long to display, scroll buttons appear at  506 A,B for scrolling the list. 
       FIG. 6  shows a display  600  for an incoming call state. The incoming call state display  600  is shown when the controlled smart remote control device  300  receives an incoming call.

Although in the described embodiments the elements of process  900  are presented in one arrangement, other embodiments may feature other arrangements. For example, in various embodiments, some or all of the elements of process  900  can be executed in a different order, concurrently, and the like. Also some elements of process  900  may not be performed, and may not be executed immediately after each other. For clarity, only one smart remote control device  300  and two video call devices  102 A,B are shown in  FIG. 9 . However, it should be understood that more than one smart remote control device  300 , and/or more than two video call devices  102 , can participate in process  900 . In addition, while the embodiment of  FIG. 9  employs stateful control of a video call device  102  during a video call, it should be understood that such stateful control can be employed outside of a video call as well. 
     Referring to  FIG. 9 , the video call devices  102 A,B conduct a video call. In particular, the first video call device  102 A receives first audio information and first video information AV 1  at  902 , for example from a local camera  232  and microphone  234 . The second video call device  102 B receives second audio information and second video information AV 2  at  904 . The video call devices  102 A,B exchange the first and second audio and video information AV 1  and AV 2  at  906 . The first video call device  102 A renders the second audio and video information AV 2  at  908 , for example on television set  106 A. The second video call device  102 B renders the first audio and video information AV 1  at  910 , for example on television set  106 B. This exchange can continue for the remainder of process  900 . 
     At  912 , the first video call device  102 A provides contextual information to the smart remote control device  300 . The contextual information indicates an operating state of the video call device  102 A. The operating states of the video call devices  102  can include any operating state, for example including the states described with reference to  FIGS. 4-8 . 
     In response to receiving the contextual information, at  914  the smart remote control device  300  displays state-specific information. For example, in response to the contextual information indicating an incoming call state for the video call device  102 A, the smart remote control device  300  shows display  600  of  FIG. 6  for an incoming call state. The state-specific display can includes state-specific commands. For the incoming call state, the commands can include the commands represented by the video button  606 , the audio button  608 , and the decline button  610 . At  916  the user selects one of the commands, for example by touching one of the buttons  606 ,  608 , and  610 . Responsive to the user selecting a command button, the smart remote control device  300  sends the corresponding command to the video call device  102 A at  918 . Responsive to receiving the command, the video call device  102 A processes the command at  920 . For example, responsive to receiving the command associated with the user touching the video button  606 , the video call device  102 A accepts the incoming call as a video call. 
     Media Content Source and Broker 
     The disclosed smart remote control devices  300  can act as media content sources and brokers.  FIG. 10  shows a video calling system  1000  where three smart remote control devices (SRCD)  300 A,B,C act as media content sources for a video call device (VCD)  102 A while the video call device  102 A is engaged in a video call according to one embodiment. Although in the described embodiments the elements of the video calling system  1000  are presented in one arrangement, other embodiments may feature other arrangements. For example, elements of the video calling system  1000  can be implemented in hardware, software, or combinations thereof. 
     Referring to  FIG. 10 , the smart remote control devices  300 A,B,C communicate with the video call device  102 A over a local network  1002  such as a WiFi local area network. Video call device  102 A is engaged in a video call with one or more other video call devices  102 B-N over a network  108  such as the Internet. 
     In  FIG. 10 , the smart remote control devices  300 A,B,C share media content with the video call device  102 A during a video call between the video call device  102 A and one or more other video call devices  102 B-N, thereby enabling the video call device  102 A to share that media content with the other video call devices  102 B-N. However, the smart remote control devices  300 A,B,C can share media content with the video call device  102 A outside a video call, for example to support local collaboration. For example, a group of engineers in a conference room can use their local video call device  102 A to collaborate using the attached TV set  106 A. 
     In  FIG. 10 , a first smart remote control device  300 A shares its microphone (MIC)  310 A, a second smart remote control device  300 B shares its camera (CAM)  306 B, while a third smart remote control device  300 C shares both its camera  306 C and microphone  310 C. The video call device  102 A shares its camera  232 A and microphone  234 A as well. The video call device  102 A renders the shared media content on TV set  106 A, and provides the shared media content to the other video call devices  102 B-N in the video call, which render the shared media content on TV sets  106 B-N. Sharing media content during a video call is disclosed in U.S. Provisional Patent Application Ser. No. 61/485,229 entitled “MEDIA SHARING DURING A VIDEO CALL,” filed May 12, 2011, and U.S. patent application Ser. No. (to be assigned), entitled “MEDIA SHARING DURING A VIDEO CALL,” filed TBD, the disclosures thereof incorporated by reference herein in their entirety. 
       FIG. 11  shows a process  1100  for the video calling system  1000  of  FIG. 10  according to an embodiment where a smart remote control device  300  acts as a media content source for a first video call device  102 A during a video call with a second video call device  102 B. Although in the described embodiments the elements of process  1100  are presented in one arrangement, other embodiments may feature other arrangements. For example, in various embodiments, some or all of the elements of process  1100  can be executed in a different order, concurrently, and the like. Also some elements of process  1100  may not be performed, and may not be executed immediately after each other. For clarity, only one smart remote control device  300  and two video call devices  102 A,B are shown in  FIG. 11 . However, it should be understood that more than one smart remote control device  300 , and/or more than two video call devices  102 , can participate in process  1100 . In addition, while in the embodiment of  FIG. 11  the smart remote control device  300  acts as a media source during a video call, it should be understood that the smart remote control device  300  can act as a media source outside of a video call as well. 
     Referring to  FIG. 11 , the video call devices  102 A,B conduct a video call. In particular, the first video call device  102 A receives first audio information and first video information AV 1  at  1102 , for example from a local camera  232  and microphone  234 . The second video call device  102 B receives second audio information and second video information AV 2  at  1104 . The video call devices  102 A,B exchange the first and second audio and video information AV 1  and AV 2  at  1106 . The first video call device  102 A renders the second audio and video information AV 2  at  1108 , for example on television set  106 A. The second video call device  102 B renders the first audio and video information AV 1  at  1110 , for example on television set  106 B. This exchange can continue for the remainder of process  1100 . 
     At  1112 , the smart remote control device  300  provides media content to the first video call device  102 A. The media content can be any sort of media content. For example, the media content can be generated by the camera  306  and microphone  310  of the smart remote control device  300 , received by the smart remote control device  300  over a communication interface, retrieved from the memory  304  of the smart remote control device  300 , or the like. At  1114 , the first video call device  102 A sends the media content to the second video call device  102 B. While the media content is being transferred, the displays at both ends of the video call can show the status of the transfer. 
     The video call devices  102  render the media content. In particular, video call device  102 A renders the media content on TV set  106 A at  1116 , and video call device  102 B renders the media content on TV set  106 B at  1118 . In some embodiments, the rendering of the media content is synchronized, for example through the exchange of synchronization commands, so that the video call devices  102  render the media content at the same time. For example, the video call devices  102  can render a photo simultaneously. As another example, the video call devices  102  can begin playback of a video file simultaneously. Such synchronization is described in U.S. Provisional Patent Application Ser. No. 61/485,229 entitled “MEDIA SHARING DURING A VIDEO CALL,” filed May 12, 2011, and U.S. patent application Ser. No. (to be assigned), entitled “MEDIA SHARING DURING A VIDEO CALL,” filed TBD, the disclosures thereof incorporated by reference herein in their entirety. 
     As media content sources, the described embodiments allow users to take advantage of existing smart phones, tablets, and multimedia-capable computers, and to make these resources available to participants in a video call. Resources on the smart remote control device  300  can be utilized as if they were local resources of the video call device  102 , for example by using the virtual interface  256  of the video call device  102 . Such resources can include, for example, wireless microphones, wireless speakers, video playback, cameras, camera functions, web page views, orientation sensors, GPS, wireless management of remote devices, touch screens, pointing devices, high resolution displays, high speed networking, video decoders, video encoders, audio recording, audio playback, web browsing, and the like. 
       FIG. 12  shows a video calling system  1200  where one smart remote control device (SRCD)  300 A acts as a media content source for a video call device (VCD)  102 A and another smart remote control device  300 B acts as a media content broker while the video call device  102 A is engaged in a video call according to one embodiment. Although in the described embodiments the elements of the video calling system  1200  are presented in one arrangement, other embodiments may feature other arrangements. For example, elements of the video calling system  1200  can be implemented in hardware, software, or combinations thereof. 
     Referring to  FIG. 12 , the smart remote control devices  300 A,B communicate with the video call device  102 A over a local network  1002  such as a WiFi local area network. Video call device  102 A is engaged in a video call with one or more other video call devices  102 B-N over a network  108  such as the Internet. 
     In  FIG. 12 , smart remote control device  300 A,B share and broker media content with the video call device  102 A during a video call between the video call device  102 A and one or more other video call devices  102 B-N, thereby enabling the video call device  102 A to share that media content with the other video call devices  102 B-N. However, the smart remote control devices  300 A,B can share and broker media content with the video call device  102 A outside a video call, for example to support local collaboration. 
     In  FIG. 12 , a first smart remote control device  300 A shares media content  1204 A with video call device  102 A, for example as described with reference to  FIGS. 10 and 11 .

Also some elements of process  1300  may not be performed, and may not be executed immediately after each other. For clarity, only one smart remote control device  300  and two video call devices  102 A,B are shown in  FIG. 13 . However, it should be understood that more than one smart remote control device  300 , and/or more than two video call devices  102 , can participate in process  1300 . In addition, while in the embodiment of  FIG. 13  the smart remote control device  300  acts as a media broker during a video call, it should be understood that the smart remote control device  300  can act as a media broker outside of a video call as well. Furthermore, while in the embodiment of  FIG. 13  the smart remote control device  300  obtains the media content to be brokered from a PC  1202 , it should be understood that the smart remote control device  300  can obtain the media content to be brokered from any device capable of providing the media content. 
     Referring to  FIG. 13 , the video call devices  102 A,B conduct a video call. In particular, the first video call device  102 A receives first audio information and first video information AV 1  at  1302 , for example from a local camera  232  and microphone  234 . The second video call device  102 B receives second audio information and second video information AV 2  at  1304 . The video call devices  102 A,B exchange the first and second audio and video information AV 1  and AV 2  at  1306 . The first video call device  102 A renders the second audio and video information AV 2  at  1308 , for example on television set  106 A. The second video call device  102 B renders the first audio and video information AV 1  at  1310 , for example on television set  106 B. This exchange can continue for the remainder of process  1300 . 
     At  1312 , the smart remote control device  300  obtains the media content from PC  1202 . The media content can be any sort of media content. At  1314 , the smart remote control device  300  sends the media content to the first video call device  102 A. At  1316 , the first video call device  102 A sends the media content to the second video call device  102 B. While the media content is being transferred, the displays at both ends of the video call can show the status of the transfer. 
     The video call devices  102  render the media content. In particular, video call device  102 A renders the media content at  1318 , and video call device  102 B renders the media content at  1320 . In some embodiments, the rendering of the media content is synchronized, for example through the exchange of synchronization commands, so that the video call devices  102  render the media content at the same time. Such synchronization is described in U.S. Provisional Patent Application Ser. No. 61/485,229 entitled “MEDIA SHARING DURING A VIDEO CALL,” filed May 12, 2011, and U.S. patent application Ser. No. (to be assigned), entitled “MEDIA SHARING DURING A VIDEO CALL,” filed TBD, the disclosures thereof incorporated by reference herein in their entirety. 
     It should be understood that media content can be brokered from any device capable of supplying the media content to a smart remote control device  300 . The media content can be supplied to a smart remote control device  300  by any means, for example by a direct wired or wireless link, as shown in  FIG. 12 , by a wired or wireless network, and the like. The media content can include any sort of media content, for example including a desktop, an application display, or the like. Sharing media content during a video call is disclosed in U.S. Provisional Patent Application Ser. No. 61/485,229 entitled “MEDIA SHARING DURING A VIDEO CALL,” filed May 12, 2011, and U.S. patent application Ser. No. (to be assigned), entitled “MEDIA SHARING DURING A VIDEO CALL,” filed TBD, the disclosures thereof incorporated by reference herein in their entirety. 
     Current video conferencing solutions do not allow for indirect media streams to pass through a constellation of networked devices. In contrast, as media content brokers, the described smart remote control devices  300  can manage such media streams to allow indirect, and offline, configuration and management separate from the video call device  102 . Devices and streams that can be managed by the smart remote control device  300  include wireless microphones, wireless cameras, screen sharing of the displays of smart remote control devices  300 , and screen sharing of a network desktop and/or application. A wireless microphone can be shared, for example, by using the on-board microphone  310  of a smart remote control device  300  or by leveraging other wireless microphone arrays, and unifying the feeds to a video call device  102 . A wireless camera can be shared, for example, by using the on-board camera  306  of the smart remote control device  300  or by leveraging other wireless cameras (for example on other smart remote control devices  300 ) and unifying the feeds to a video call device  102 . The smart remote control devices  300  can also broker media content from other smart remote control devices  300  and other video call devices  102 . The smart remote control devices  300  can also perform media transcoding to match video call device  102  resources if necessary, thereby relieving the video call device  102  of the processing burden.
