Title: Control of large screen display using wireless portable computer and facilitating selection of audio on a headphone

Description:
FIELD OF THE INVENTION 
     The application relates generally to controlling a large screen display using a wireless portable computer such as a tablet or laptop computer interfacing with a display controller such as a game console. 
     BACKGROUND OF THE INVENTION 
     A computer ecosystem, or digital ecosystem, is an adaptive and distributed socio-technical system that is characterized by its sustainability, self-organization, and scalability. Inspired by environmental ecosystems, which consist of biotic and abiotic components that interact through nutrient cycles and energy flows, complete computer ecosystems consist of hardware, software, and services that in some cases may be provided by one company, such as Sony. The goal of each computer ecosystem is to provide consumers with everything that may be desired, at least in part services and/or software that may be exchanged via the Internet. Moreover, interconnectedness and sharing among elements of an ecosystem, such as applications within, a computing cloud, provides consumers with increased capability to organize and access data and presents itself as the future characteristic of efficient integrative ecosystems. 
     Two general types of computer ecosystems exist: vertical and horizontal computer ecosystems. In the vertical approach, virtually all aspects of the ecosystem are owned and controlled by one company, and are specifically designed to seamlessly interact with one another. Horizontal ecosystems, one the other hand, integrate aspects such as hardware and software that are created by other entities into one unified ecosystem. The horizontal approach allows for greater variety of input from consumers and manufactures, increasing the capacity for novel innovations and adaptations to changing demands. 
     SUMMARY OF THE INVENTION 
     An example ecosystem that is pertinent here is an entertainment ecosystem in the home or in a luxury suite at a stadium that includes a large screen high definition display controlled by a controller such as a personal computer (PC) or game console which receives commands from a portable control device such as a tablet computer. 
     Accordingly, a monitoring device includes at least one computer readable storage medium bearing instructions executable by a processor, and at least one processor configured for accessing the computer readable storage medium to execute the instructions to configure the processor for receiving at least one software application executable by the processor. The instructions when executed by the processor configure the processor for executing the application to present on the monitoring device a list of plural audio feeds, with each audio feed corresponding to a respective video content being simultaneously provided to a display device separate from the monitoring device. In this way, the display device can simultaneously present at least first and second video contents on a display thereof but play only first audio associated with only the first video content. The instructions when executed by the processor configure the processor for receiving selection of an audio feed from the list, and responsive to the selection, playing the audio feed on the monitoring device. 
     In some examples, the selection is such that a user of the monitoring device can view the display device and listen to the second audio on the monitoring device while viewing the second video content on the display device with the display device playing the first audio. The playing of the audio feed may be executed by playing the audio feed on headphones. The monitoring device may be established by a wireless telephone. 
     In examples, the processor when executing the instructions is configured for receiving the software application by imaging a bar code disposed on or near the display device and correlating the bar code to a network address at which the software application is available. The processor when executing die instructions may be configured for playing the audio feed on the monitoring device responsive to downloading the audio feed from a computer network. 
     In another aspect, a system includes a display device configured for presenting plural video contents in respective windows of the display device and for playing first audio associated with a first one of the video contents. The system includes a controller configured for controlling the display device, and a control device configured for communicating commands to the controller to control presentation on the display device. A monitoring device is configured for playing second audio associated with a second one of the video contents on the display device while the display device plays the first audio and presents the first and second video contents simultaneously. 
     In another aspect, a method includes providing plural video contents to a display device for simultaneous presentation thereof on the display device. The method includes providing plural audio streams to the display device for presentation of a user-selected one of the audio streams on the display device, the audio streams corresponding to respective ones of the video contents. Also, the method includes providing a list of the audio streams to a monitoring device for selection of one of the audio streams for play on the monitoring device, such that a user of the monitoring device can view the display device and listen to a first audio stream on the monitoring device while viewing a respective first video content on the display device with the display device playing a second audio stream associated with a second video content. 
     The details of the present invention, both as to its structure and operation, can be best understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

     Components included in one embodiment can be used in other embodiments in any appropriate combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged or excluded from other embodiments. 
     “A system having at least one of A, B, and C” (likewise “a system having at least one of A, B, or C” and “a system having at least one of A, B, C”) includes systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B and C together, etc. 
     Now specifically referring to  FIG. 1 , an example ecosystem  10  is shown, which may include one or more of the example devices mentioned above and described further below in accordance with present principles. The first of the example devices included in the system  10  is an example primary display device, and in the embodiment shown is an audio video display device (AVDD)  12  such as but not limited to an Internet-enabled TV. Thus, the AVDD  12  alternatively may be an appliance or household item, e.g. computerized Internet enabled refrigerator, washer, or dryer. The AVDD  12  alternatively may also be a computerized Internet enabled (“smart”) telephone, a tablet computer, a notebook computer, a wearable computerized device such as e.g. computerized Internet-enabled watch, a computerized Internet-enabled bracelet, other computerized Internet-enabled devices, a computerized Internet-enabled music player, computerized Internet-enabled head phones, a computerized Internet-enabled implantable device such as an implantable skin device, etc. Regardless, it is to be understood that the AVDD  12  is configured to undertake present principles (e.g. communicate with other CE devices to undertake present principles, execute the logic described herein, and perform any other functions and/or operations described herein). 
     Accordingly, to undertake such principles the AVDD  12  can be established by some or all of the components shown in  FIG. 1 . For example, the AVDD  12  can include one or more displays  14  that may be implemented by a high definition or ultra-high definition “4K” flat screen and that may be touch-enabled for receiving user input signals via touches on the display. The AVDD  12  may include one or more speakers  16  for outputting audio in accordance with present principles, and at least one additional input device  18  such as e.g. an audio receiver/microphone for e.g. entering audible commands to the AVDD  12  to control the AVDD  12 . The example AVDD  12  may also include one or more network interfaces  20  for communication over at least one network  22  such as the Internet, an WAN, an LAN, etc. under control of one or more processors  24 . Thus, the interface  20  may be, without limitation, a Wi-Fi transceiver, which is an example of a wireless computer network interface. It is to be understood that the processor  24  controls the AVDD  12  to undertake present principles, including the other elements of the AVDD  12  described herein such as e.g. controlling the display  14  to present images thereon and receiving input therefrom. Furthermore, note the network interface  20  may be, e.g., a wired or wireless modem or router, or other appropriate interface such as, e.g., a wireless telephony transceiver, or Wi-Fi transceiver as mentioned above, etc. 
     In addition to the foregoing, the AVDD  12  may also include one or more input ports  26  such as, e.g., a USB port to physically connect (e.g. using a wired connection) to another CE device and/or a headphone port to connect headphones to the AVDD  12  for presentation of audio from the AVDD  12  to a user through the headphones. The AVDD  12  may further include one or more tangible computer readable storage medium  28  such as disk-based or solid state storage. Also in some embodiments, the AVDD  12  can include a position or location receiver such as but not limited to a cellphone receiver, GPS receiver and/or altimeter  30  that is configured to e.g. receive geographic position information from at least one satellite or cellphone tower and provide the information to the processor  24  and/or determine an altitude at which the AVDD  12  is disposed in conjunction with the processor  24 . However, it is to be understood that that another suitable position receiver other than a cellphone receiver, GPS receiver and/or altimeter may be used in accordance with present principles to e.g. determine the location of the AVDD  12  in e.g. all three dimensions. 
     Continuing the description of the AVDD  12 , in some embodiments the AVDD  12  may include one or more cameras  32  that may be, e.g., a thermal imaging camera, a digital camera such as a webcam, and/or a camera integrated into the AVDD  12  and controllable by the processor  24  to gather pictures/images and/or video in accordance with present principles. Also included on the AVDD  12  may be a Bluetooth transceiver  34  and other Near Field Communication (NFC) element  36  for communication with other devices using Bluetooth and/or NFC technology, respectively. An example NFC element can be a radio frequency identification (RFID) element. 
     Further still, the AVDD  12  may include one or more auxiliary sensors  37  (e.g., a motion sensor such as an accelerometer, gyroscope, cyclometer, or a magnetic sensor, an infrared (IR) sensor, an optical sensor, a speed and/or cadence sensor, a gesture sensor (e.g. for sensing gesture command), etc.) providing input to the processor  24 . The AVDD  12  may include still other sensors such as e.g. one or more climate sensors  38  (e.g. barometers, humidity sensors, wind sensors, light sensors, temperature sensors, etc.) and/or one or more biometric sensors  40  providing input to the processor  24 . In addition to the foregoing, it is noted that the AVDD  12  may also include an infrared (IR) transmitter and/or IR receiver and/or IR transceiver  42  such as an IR data association (IRDA) device. A battery (not shown) may be provided for powering the AVDD  12 . 
     Still referring to  FIG. 1 , in addition to the AVDD  12 , the system  10  may include one or more other CE device types. In one example, a first CE device  44  may be used to control the display via commands sent through the below-described server while a second CE device  46  ma include similar components as the first CE device  44  and hence will not be discussed in detail. In the example shown, only two CE devices  44 ,  46  are shown, it being understood that fewer or greater devices may be used. 
     In the example shown, to illustrate present principles all three devices  12 ,  44 ,  46  are assumed to be members of an entertainment network in, e.g., a luxury suite of the stadium, or in a home, or at least to be present in proximity to each other in a location such as a house. However, for illustrating present principles the first CE device  44  is assumed to be in the same room as the AVDD  12 , bounded by walls illustrated by dashed lines  48 . 
     The example non-limiting first CE device  44  may be established by any one of the above-mentioned devices, for example, a portable wireless laptop computer or notebook computer, and accordingly may have one or more of the components described below. The second CE device  46  without limitation may be established by a wireless telephone. 
     The first CE device  44  may include one or more displays  50  that may be touch-enabled for receiving user input signals via touches on the display. The first CE device  44  may include one or more speakers  52  for outputting audio in accordance with present principles, and at least one additional input device  54  such as e.g. an audio receiver/microphone for e.g. entering audible commands to the first CE device  44  to control the device  44 . The example first CE device  44  may also include one or more network interfaces  56  for communication over the network  22  under control of one or more CE device processors  58 . Thus, the interface  56  may be, without limitation, a Wi-Fi transceiver, which is an example of a wireless computer network interface. It is to be understood that the processor  58  controls the first CE device  44  to undertake present principles, including the other elements of the first CE device  44  described herein such as e.g. controlling the display  50  to present images thereon and receiving input therefrom. Furthermore, note the network interface  56  may be, e.g., a wired or wireless modem or router, or other appropriate interface such as, e.g., a wireless telephony transceiver, or Wi-Fi transceiver as mentioned above, etc. 
     In addition to the foregoing, the first CE device  44  may also include one or more input ports  60  such as, e.g., a USB port to physically connect (e.g. using a wired connection) to another CE device and/or a headphone port to connect headphones to the first CE device  44  for presentation, of audio from the first CE device  44  to a user through the headphones. The first CE device  44  may further include one or more tangible computer readable storage medium  62  such as disk-based or solid state storage. Also in some embodiments, the first CE device  44  can include a position or location receiver such as but not limited to a cellphone and/or GPS receiver and/or altimeter  64  that is configured to e.g. receive geographic position information from at least one satellite and/or cell tower, using triangulation, and provide the information to the CE device processor  58  and/or determine an altitude at which the first CE device  44  is disposed in conjunction with the CE device processor  58 . However, it is to be understood that that another suitable position receiver other than a cellphone and/or GPS receiver and/or altimeter may be used in accordance with present principles to e.g. determine the location of the first CE device  44  in e.g. all three dimensions. 
     Continuing the description of the first CE device  44 , in some embodiments the first CE device  44  may include one or more cameras  66  that may be, e.g., a thermal imaging camera, a digital camera such as a webcam, and/or a camera integrated into the first CE device  44  and controllable by the CE device processor  58  to gather pictures/images and/or video in accordance with present principles. Also included on the first CE device  44  may be a Bluetooth transceiver  68  and other Near Field Communication (NEC) element  70  for communication with other devices using Bluetooth and/or NFC technology, respectively. An example NFC element can be a radio frequency identification (RFID) element. 
     Further still, the first CE device  44  may include one or more auxiliary sensors  72  (e.g., a motion sensor such as an accelerometer, gyroscope, cyclometer, or a magnetic sensor, an infrared (IR) sensor, an optical sensor, a speed and/or cadence sensor, a gesture sensor (e.g. for sensing gesture command), etc.) providing input to the CE device processor  58 . The first CE device  44  may include still other sensors such as e.g. one or more climate sensors  74  (e.g. barometers, humidity sensors, wind sensors, light sensors, temperature sensors, etc.) and/or one or more biometric sensors  76  providing input to the CE device processor  58 . In addition to the foregoing, it is noted that in some embodiments the first CE device  44  may also include an infrared (IR) transmitter and/or IR receiver and/or IR transceiver  78  such as an IR data association (IRDA) device. A battery (not shown) may be provided for powering the first CE device  44 . 
     The second CE device  46  may include some or all of the components shown for the CE device  44 . 
     Now in reference to the afore-mentioned at least one server  80 , it includes at least one server processor  82 , at least one tangible computer readable storage medium  84  such as dish-based or solid state storage, and at least one network interface  86  that, under control of the server processor  82 , allows for communication with the other devices of  FIG. 1  over the network  22 , and indeed may facilitate communication between servers and client devices in accordance with present principles. Note that the network interface  86  may be, e.g., a wired or wireless modem or router, Wi-Fi transceiver, or other appropriate interface such as, e.g., a wireless telephony transceiver. 
     Accordingly, in some embodiments the server  80  may be an Internet server, and may include and perform “cloud” functions such that the devices of the system  10  may access a “cloud” environment via the server  80  in example embodiments. Or, the server  80  may be implemented by a game console or other computer in the same room as the other devices shown in  FIG. 1  or nearby. 
       FIG. 2  shows an example system  100  in which first and second ultra high definition (UHD) displays  102 ,  104  are mounted on a wall e.g., a wall of a home or a luxury stadium box. The UHD displays  102 ,  104  may be 4K displays. One or more control devices control presentation of the displays by sending commands wirelessly and/or over wired paths to one or more controllers. In the non-limiting example shown, a controller  106  controls the displays  102 ,  104 , it being understood that a separate controller may be provided for each display. In the non-limiting example shown, content control on the first display  102  is established by a first control device  108  while content control an the second display  104  is established by a second control device  110 , it being understood that a single control device may be used to establish control on both displays. 
     The control devices  108 ,  110  may be, without limitation, portable computers such as tablet computers or laptop computers (also including notebook computers) or other devices with one or more of the CE device  44  components shown in  FIG. 1 . The displays  102 ,  104  may be monitors only and/or may include one or more of the primary display  14  components show in  FIG. 1 . The controller  106  may be a personal computer (PC) or game console or server that contains one or more of the components variously shown in  FIG. 1 . In the non-limiting example shown, the control devices  108 ,  110  communicate directly with the controller  106  using, e.g., WiFi or Bluetooth; the control devices  108 ,  110  do not communicate directly with the displays  102 ,  104 . Instead, the controller  106  communicates with the displays  102 ,  104  to establish presentation thereon in accordance with commands received from the control devices. It is to be understood that while the controller  106  is shown physically separate from the displays in  FIG. 2 , it may be incorporated within the chassis of a display. As also shown, the displays may present plural contents in respective content windows  112 . 
     The controller  106  may receive video from plural video cameras  114 . In the stadium context, a first camera  114  may image a first half of a sports field, racetrack, or other action venue whereas as second camera  114  may image tire other half of the action venue, with the feeds from the two cameras being combined before being sent to the controller  106  or combined by the controller  106  and “stitched” to present a single video view of both halves of the action venue on one or both of the displays  102 ,  104 . That is, the combined feed from both cameras may be presented on a single display in an 8K mode, or the combined feed may be spread across the juxtaposed displays such that one display shows one half of the action venue and the other display shows the other half. It will be appreciated that the feeds sent to the controller preferably are HD or more preferably UHD. 
     As well, the cameras  114  (through appropriate image processing down-resolution components) can present the same video feeds albeit at a lower resolution to the control devices  108 ,  110 . The UHD feeds may be sent to the controller  106  over a network from a network address while the lower resolution feeds of the same content may be simultaneously sent to the control devices  108 ,  110  over the network from the same or a different network address, such that the video content on the control devices is the same as the video content presentable on the displays, albeit typically of a lower resolution. 
     Note that a dedicated local server or PS4 may not be required in some embodiments to manage the 4K and thumbnail feeds as well as analyze the commands coming from the tablet. Instead, this can happen in the cloud with the 4K TV and tablet having their own MAC address and the cloud server acting as though it were local to permit control of 4K monitors in remote locations as well. 
     A location sensing system such as any of those described above may be used to determine where the control device is relative multiple 4K display locations to allow the user to roam and have the 4K content follow him. This provides for multiple 4K clusters in a stadium suite, each showing the same or different content. In this case what is showing on a particular 4K TV cluster can drive the UI on the tablet, or the other way around. 
     Additionally, each camera typically is associated with one or more microphones for capturing audio associated with the video to establish respective audio video (AV) streams. As more fully described below in reference to  FIG. 8 , the audio from the AV streams as well as other audio may be separately provided to a tertiary monitoring device such as a headphone-equipped wireless phone to enable a user of the monitoring device to monitor any audio associated with any of the videos shown in the various windows of the display regardless of which audio the speakers of the display itself are playing. 
     In  FIG. 3 , a control device such as the control device  108  shown in  FIG. 2  presents on its display a user interface (UI)  116  of a user interface (UI) presenting a video image of content and a border  118  superimposed on a portion  120  of the video image which is smaller than the video image as shown. For illustration, assume the video image in  FIG. 3  is of a football game, with “Os” representing offensive players and “Xs” representing defensive players. 
     When a user has instantiated the border  118  (by, e.g., selecting a “pan and zoom” selector  122 ), the control device in response sends a command to the controller to cause a large display such the display  102  in  FIG. 2  to present on the display  102  only the (higher definition) portion of the content enclosed in the border  118  on the control device  108 . In the illustration shown, the user has positioned the border  118  on the control device  108  over two offensive players and two defensive players with subscripts “1” to distinguish them from the other player symbols in the figure. In response, the control device, as indicated by the arrow  124 , has commanded the controller to present on the display device  102  only the content enclosed by the border on the control device, in the example shown, to present only the two offensive players and two defensive players with subscripts “1”. It will readily be appreciated that the controller further has zoomed the video presentation on the demanded portion to substantially fill the entire screen of the display device  102 . 
     In one example, the screen of the control device  108  is a touch screen display, and a user may touch the border  118  and/or portion enclosed thereby and drag (as indicated by the arrow  126 ) the border to a new portion of the video as indicated by the dotted line box  128 , releasing the user touch once the border has been dragged to the desired part of the video shown on the control device. In the new portion  128 , two defensive players “X” are shown, denoted by subscripts “ 2 ” to distinguish them. As indicated by the arrow  130 , this drag and drop causes the controller to pan the zoomed video from the first portion to the second portion in the direction of the drag until the second portion of the (higher definition) video substantially fills the screen of the display device  102  as shown at  132  in the figure. 
     Thus, responsive to the drag and drop of the border  118  on the control device  108 , the content related to the video image on the display device  102  is entirely established, in temporal sequence, by a zoomed presentation of the first portion, then a moving pan across at least part of the video image on the display device in concert with the user input to move the border to the second portion of the video image on the control device, to end at a zoomed presentation on the display device of the second portion. During the drag and drop process, the control device presents both the entire video image of the content and the border  118  superimposed on the portion  120  of the video image as the user input causes the border to move across the video image of the content, whereas the display device  102  is caused to present only content from the video image corresponding to content  120  within the border  118  on the control device. 
     HTML5 may be used along with JavaScript (including some JavaScript libraries), and CSS in one implementation. Video files may be stored locally on the control device and played in the browser using the video tag of HTML5. Live streaming files from a local streaming server, streaming files from internet and live tuner signal can also be used as the source. To select a different file, a user drags and drops a tile; based on the id of the tile, the path of the video in the quad portion (on which the tile id dropped) of the display presenting video in four quadrants selected is changed to the correct video and this new video is played. A full screen API may not be used since it requires user interaction to allow full screen on the control device. Accordingly, as a workaround for full screen, all videos can be paused, then the video selected can be scaled by the browser to 4K resolution. If a 4K file is present, the 4K file is used, then no browser scaling is needed. Websocket may be used to communicate through IP from the control device to the controller to control the display device. Messages may be broadcast to all the display devices, then each display device browser can use the message it needs. Drag and drop can be done using the jQuery UI library, and scrolling can be done using CSS position updating. The stitch image zoom effect can be done by drawing video on the HTML5 canvas, sending coordinates from control device to the controller so the controller knows which portion of the video to zoom on in the display device. 
     A phone application may also be implemented in HTML5, allowing audio files from the server to be played on a speaker, e.g., of the display device or other device, through IP. The phone application audio matches the audio for the four videos played in the quad view, and each audio file can be selected for playback. When selecting an external device connected to a different HDMI input of the display device (such as video disk player, a satellite feed, etc.), when a user drags the appropriate tile for the external device, the control device may send IP commands to the display device (via the controller) to change input. If a tile corresponding to a video is drag and dropped, another IP command can be sent to the display device (via the controller) to change input back to PC and/or controller and the video file selected is played from the PC and/or controller. 
       FIGS. 4-7  illustrate additional principles that may be used according to present principles. On the left side of  FIG. 4 , one of the display devices  102  from  FIG. 2  and one of the control devices  108  are shown schematically, and on the right side of  FIG. 4  the same devices are shown schematically after an operation. As shown on the left side of  FIG. 4 , a multi-view channel has been launched on the display device  102 , resulting in four video windows  400  (“quad view”) being presented on the display device  102 . Each window  400  presents a video stream from a respective audio video (AV) program P 1 -P 4  from an Internet or broadcast source (cable, satellite, etc.). The audio from only one of the AV programs is played by the display device. The windows  400  may be substantially identical in size if desired, as shown. 
     A UI  402  is presented on the display of the control device  108 . As shown, the UI  402  includes plural main selectors  404  arranged in a layout, preferably the same layout as the windows  400  on the display device  102  as shown. Each main selector  404  is established by a respective video feed, in the example shown, the same content albeit perhaps in lower resolution as the four videos in the quad view of the display device  102 , as duly indicated by use of the same video program designators P 1 -P 4 . 
     The UI  402  may further include a row  406  of additional content selectors  408  apart from the programs P 1 -P 4  shown in the main selectors  404 , although in the embodiment shown, for ease of disclosure, the same four programs P 1 -P 4  establish the first four content selectors  408  in the row  406 , while the last two content selectors indicate they may be selected to present content from two additional programs P 5  and P 6 . In some embodiments, unlike the main selectors  404 , which recall are established by moving video, the content selectors  408  in the row  406  may be established by still image thumbnails. 
     Furthermore, a column  410  of audio selectors  412  may be presented on the UI  402 . Each volume selector  412  in the column  410  may correspond to a respective content in the content selectors  408  in the row  406 . Each audio selector  412  may include a respective audio on/off symbol  414 , with all of the symbols  414  except one having a line through them indicating that the audio represented by those selectors is not being played on the display device  102 . In contrast, in the example shown the symbol  414  of the top audio selector  412  does not have a line through it, indicating that the audio from the program associated with the top selector, in the example shown, program P 1 , is being played on the display device  102 . Touching an audio selector  412  on the control device  108  causes the control device to command the controller to switch audio play on the display device  102  to the audio represented by the touched audio selector on the control device  108 . This also causes the line through the respective symbol  414  of the touched selector to be removed, and a line placed onto the symbol  414  of the selector  412  representing the replaced audio. 
     The right side of  FIG. 4  illustrates the dragging and dropping one of the content selectors  408  onto a main selector  404  changes the video in that main selector  404  to the video represented by the dragged and dropped content selector  408 . Not only does the UI  402  on the control device  108  thus change, but also, as indicated in the top right portion of  FIG. 4 , the video presented in the window  400  (in this, the top left window) of the display device  102  is also caused to change to the video represented by the dragged and dropped content selector  408 . This may be done by the control device  108 , responsive to the drag and drop, obtaining the network address or channel number of the video represented by the dragged and dropped content selector  408  and commanding the controller to present video from that network address in the window  400  corresponding to the main selector  404  onto which the content selector  408  was dragged and dropped. In any case, it will readily be appreciated that the main selectors  404  on the control device  108  mirror the windows  400  on the display device  102 . A user may move his hand left or right on the row  406  of content selectors to cause selectors for additional content to scroll onto the display of the control device. The new content typically includes additional program channels or Internet content related to the theme of the programming presented on the display device  102 , including, for example, sports statistics related to a sporting event in one of the windows  400 . 
     The left side of  FIG. 5  illustrates that “throwing” one of the main selectors  404  on the control device  108  “to” the display device  102  causes the display device to switch to a full screen presentation  500  (shown on the right of  FIG. 5 ) of the content represented by the “thrown” main selector  404 . The processor of the control device  108  may infer that a main selector  404  has been “thrown” by a user dragging the main selector upwards toward the top of the control device, responsive to which the control device  108  sends a command to the controller to present the associated content full screen on the display device  102 . 
     Although not shown in  FIG. 5 , commanding the display device  102  into the full screen mode as described above may result in the main selectors  404  on the control device  108  merging into a single large selector with the same content shown full screen on the display device. However, the row  406  of content selectors  406  and column  410  of audio selectors  412  can remain unchanged. This single large main selector in the area formerly occupied by the four main selectors may be touched to cause the display device (pursuant to a command from the control device) to revert to the quad view shown on the left side of  FIG. 5  and to also cause the main selectors  404  on the control device  108  to mirror the display device views. In this case, to resume the four main selector quad view show on the bottom left of  FIG. 4 . 
     Alternatively, throwing a main selector  404  to cause the display device to enter full screen mode as described may not alter the appearance of the main, selectors  404 , which can remain in the quad view shown on the control device. Subsequently touching any one of the main selectors  404  on the control device may result in the control device commanding the controller to resume the quad view presentation on the display device. Or, if desired, as shown on the bottom right of  FIG. 5 , when the control device has been configured to command the display device to enter full screen mode, with the four main selectors  404  remaining on the control device UI, touching one of the main selectors may cause the corresponding content to be presented full screen on the control device. The content presented full screen on the display device may be the same or different than the content presented full screen on the control device, depending on what main selector  404  was thrown to the display device and what main selector  404  subsequently was touched by a user. A subsequent touch anywhere on the control device screen may cause the control device and display device to resume the layouts shown on the left side of  FIG. 5 . 
     To view the details of any content represented by a content selector  408 , as shown in the left side of  FIG. 6  a user may simply touch the content selector  408 . This may cause a detail screen  600  to appear on the control device  108  (but not on the display device  102 ), so that a person controlling presentation on the display device by means of the control device  108  can observe the detailed information about content prior to presenting the content (or information about the content) on the display device  102 . 
       FIG. 7  is a series of screen shots on the control device  108  to illustrate further optional details. A remote control selector  702  may be presented which if touched as indicated at  704  can cause a remote-control like presentation  706  to be presented on the control device  108 . The presentation  706  emulates a standard remote control, with alpha-numeric touch-enabled input selectors, channel and volume up/down selectors, and cursor arrow selectors as shown. Touching the selector  702  again causes the initial presentation (upper right panel in  FIG. 7 ) to resume on the control device. 
     When a single control device  108  is used to control both display device  102  shown in  FIG. 2 , as shown at  708  in  FIG. 7  main selectors  710  corresponding to the quad view of a first one of the display devices  102  may be presented and used to control that display device according to principles above. Also, a smaller quad view of alternate main selectors  712  may be presented, representing content being presented on the second display device  102 . To enable control of the second display device  102  using the control device  108 , a user need only touch the smaller quad view of alternate main selectors  712  as shown at  714 , causing the smaller quad view of alternate main selectors  712  to animate to an enlarged configuration  716  and the quad view of main selectors corresponding to the first one of the display devices  102  to animate to become smaller in size as shown at  718 . The enlarged configuration of main selectors on the control device  108  appertaining to the second display device  102  may then be used to control the presentation on the second display device according to principles above. 
     The bottom two screen shots in  FIG. 7  show that tapping  720  on a content selector can cause a detail presentation  722  to be shown on the control device, showing the details of the content represented by the tapped content selector. Also, as shown at  724 , instead of a column of audio selectors as described previously, respective audio on/off symbols analogous to the symbols  414  in  FIG. 4  may be presented on each main selector  726  and if touched cause the control device to command the controller to replace the associated audio with the touched symbol to replace the audio currently being played on the display device being controlled. 
     While a four screen quad view is discussed and shown, any number of windows in a multi-window arrangements may be used. 
       FIG. 8  shows a dual display device system similar to the system shown in  FIG. 2  and described above, with the following additional features. Two display devices  800  may be controlled by respective controllers  802  responsive to commands input from respective control devices  804 . Additionally, an audio control device  806  may be provided that may be substantially identical in construction to the control devices  804  for controlling which audio is played on the speakers of the display devices  800 . Thus, each of the control devices  804 ,  806  may have some or all of the components of one of the CE devices shown in  FIG. 1 . 
     Only a single audio preferably is selected for play because, recall, the display devices as shown have multiple video windows, but it is desired to play only audio associated with video in a single one of the windows to avoid distracting overlapping audio. When the displays are side by side or otherwise positioned near each other, both display devices may play the same audio regardless of whether the accompanying video is shown on only one or both of the display devices. 
     As shown, the audio control device  806  may present a list, e.g., in a column, of thumbnail-like audio selectors  808 , each being selectable to cause the audio control device  806  to command, e.g., wirelessly, the controllers  820 ,  804  to play on the display devices  800  the audio represented by the selected audio selector  808 . 
     In one non-limiting example, a user of the audio control device  806  may use the camera of the device  806  to image a bar code  810  on a substrate  812  located in the same room as the other devices shown in  FIG. 8 . The bar code may include, e.g., a network address of a web site that the processor of the audio control device  806  reads and in response invokes a browser to navigate to the web site. Of course, other means for the audio control device  806  to obtain the address of the web site hosting the audio selector UI may be used. The web site may download an application such as an application programming interface (API) to the audio control device  806 , or may otherwise provide the UI with the audio selectors  808  as shown to the audio control device  806 . It is to be appreciated that the web site associated with the network address from which the UI with the audio selectors  808  is obtained is typically associated with the network sources of the various video streams presented in the windows of the display devices  800 , so that for each video stream presented in a window of a display device  800 , the audio web site provides a respective audio selector in the list presented on the audio control device  806  that may be selected to cause audio associated with the video stream to be played on speakers of the display device(s)  800  according to discussion above. 
     It will now be appreciated that while multiple video streams can be presented on the display device(s)  800 , to avoid distracting overlapping audio, the display device(s) play only a single audio stream associated with one of the videos. As recognized herein, however, when multiple people are in the room, one or more of them may wish to unobtrusively listen to an audio stream that is associated with one the video streams being presented on the display device(s)  800  but that is not the audio stream selected for play by the display device(s)  800 . Accordingly, a tertiary or monitoring device  814  that can receive audio and play it on headphones  816  that are connected to the monitoring device  814  wired or wirelessly may be employed as described below. In an example, the monitoring device  814  may be the wireless smart phone of the user and thus may incorporate some or all of the components shown in the CE devices of  FIG. 1 . Note that “headphones” includes any private listening apparatus including, for example, ear buds. 
     As shown in  FIG. 8 , the monitoring device  814  can present a list  818  of plural audio feeds, with each audio feed corresponding to a respective video content being simultaneously provided to a display device  800  that is separate from the monitoring device  814 . The list  818  includes plural audio selectors  820 , and selecting an audio selector  820  causes the monitoring device  814  to play an audio feed associated with the selected audio selector  820  on the monitoring device, and preferably to play the audio on the headphones  816  of the monitoring device. In this way, a user of the monitoring device  814  can view the display device(s)  800  and listen to audio on the monitoring device  814  that is associated with video content being presented in one of the windows of the display device  800  but that is not the audio being played on the display device(s)  800 . 
     In one non-limiting example, a user of the monitoring device  814  may use the camera of the device  814  to image the bar code  810  which, recall, may include, e.g., a network address of a web site that the processor of the monitoring device  814  reads and in response invokes a browser to navigate to the web site. Of course, other means for the monitoring device  814  to obtain the address of the web site hosting the audio selector UI may be used. The web site may download an application such as an application programming interface (API) to the monitoring device  814 , or may otherwise provide the UI with the audio selectors  820  as shown to the monitoring device  814 . It is to be appreciated that the web site associated with the network address from which the UI with the audio selectors  820  is obtained is typically associated with the network sources of the various video streams presented in the windows of the display devices  800 , so that for each video stream presented in a window of a display device  800 , the audio web site provides a respective audio selector in the list presented on the monitoring device  814  that may be selected to cause audio associated with the video stream to be downloaded from the web site and played on the headphones  816 . 
     Without limitation, the audio provided from the web site to the monitoring device may be extracted from the AV streams provided by the cameras with associated microphones. This extraction may be effected using an extraction tool such as “FFmpeg” and/or may extract the audio file from an AV object by recognizing and extracting audio file extensions such as but not limited to “mp3”, “aac”, etc. 
     While the particular CONTROL OF LARGE SCREEN DISPLAY USING WIRELESS PORTABLE COMPUTER AND FACILITATING SELECTION OF AUDIO ON A HEADPHONE is herein shown and described in detail, It is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
