The present invention relates to methods, systems, and apparatuses for remote control activity detection.
A typical home entertainment system may consist of a variety of different multimedia devices, such as a television (TV), a cable/satellite set-top box (STB), video game consoles such as Xbox™ or Playstation™, media streaming devices, such as Roku™, AppleTV™, Chromecast™, and a host of other devices, such as Blu-ray™ players, digital video disc (DVD) and compact disc (CD) players. Very often, these devices are connected through an audio-video receiver (AVR). A user's interaction with these devices can be classified into four distinct set of operations: (1) initial setup; (2) switching sources and control of devices; (3) accessing and controlling content playback; and (4) reconfiguration of the system when devices are added or removed.
The initial setup of multimedia devices not only includes wiring and connections, which can be quite intimidating, but also involves setting up a myriad of options in each of the devices. The crow's nest of wires makes it extremely difficult to trace back the connections in case one needs to make any changes. Furthermore, High-Definition Multimedia Interface (HDMI) interfaces require a user to identify which HDMI ports are input ports and which HDMI ports are output ports, thereby making setup even more complicated. Moreover, many TVs today are installed on the wall, which makes finding and reaching HDMI ports on the back of such TVs extremely difficult, let alone aligning the right cable so that it can be inserted into the port properly.
Once devices are connected, it becomes quite difficult to remember which device is connected to which port. Thus, switching between devices accurately becomes quite a struggle. For example, if a user wants to switch to a video game console, the user has to remember the port to which the game console is connected. As described above, devices, such as TVs and AVRs, require HDMI ports to be manually configured using menu options to identify which device is connected to which port. However, this option is quite cumbersome and seldom performed by the user.
In addition, the TV and AVR remote controls are difficult to use, but are essential to control the devices and other functions. For example, the TV or AVR remote control is required for selecting a particular device and other operations, such as volume control. However, due to the limited functionality of the TV or AVR remote control, the user needs to find and operate the device's remote control to start controlling the device (e.g., play, pause, stop, etc.). Thereafter, if the user decides to watch a program on the cable STB, he has to once again find the TV remote, remember which port the set-top box was connected to, switch to that port, and then operate the STB remote control and use it to control the device.
Methods, systems, and apparatuses are described for remote control activity detection, which may be utilized, for example, in the control of home entertainment devices and other connected devices, such as home automation equipment, substantially as shown in and/or described herein in connection with at least one of the figures, as set forth more completely in the claims.

Example embodiments described herein enable a switching device to automatically select one or more AV ports that are coupled to one or more electronic devices that a user would like to use to watch and/or listen to content. The AV port(s) may be automatically selected based on determining that an RF remote control device is being used. Upon determining that an RF remote control device is being used, a source device for providing content is identified from among a plurality of source devices. Thereafter, an AV port from among a plurality of AV ports to which the identified source device is connected is identified. The identified AV port is then selected so that the identified source device becomes connected to one or more AV ports to which one or more sink devices are connected. In this way, the switching device can provide content from the identified source device to the sink device for playback.
In another embodiment, upon determining that an RF remote control device is being used, a source device from among a plurality of source devices or a sink device from among a plurality of sink devices is controlled, for example, by powering on or powering off the source or sink device. In another embodiment, upon determining that an RF remote control device is being used, another device that is neither a source nor a sink device is controlled, such as an electronic device or a home automation device. In this manner, a switching device may automatically control one or more additional devices upon detecting that an RF remote control device is being used.
Electronic devices 102A-102C are configured to provide audio and/or video signals (e.g., audio and/or video signals 108A, 108B, 108C, respectively) for playback and are referred to as “source” devices. Electronic device 102D is configured to receive audio and/or video signals (e.g., audio and/or video signals 112) and is referred to as a “sink” device. As shown in
Switching device 104 is configured to select (e.g., switch between) different audio and/or video source devices that are coupled to AV ports 110A-110C (e.g., electronic device 102A, electronic device 102B or electronic device 102C) and provide an output signal (e.g., audio and/or video signals 112) comprising audio and/or video signals (e.g., audio and/or video signals 108A, audio and/or video signals 108B or audio and/or video signals 108C) provided by the selected audio/video source. Audio and/or video signals 112 are provided to electronic device 102D that is coupled to AV port 110D. Audio and/or video signals 112 may also be provided to any other device capable of playing back audio and/or video signals (e.g., speakers) that may be coupled to AV port 102D and/or other port(s) (not shown) of switching device 104.
Each of AV ports 110A-110D may be configurable to be coupled to either a source device (e.g., electronic device 102A, electronic device 102B, or electronic device 102C) or a sink device (e.g., electronic device 102D). For example, switching device 104 may be configured to automatically determine whether an electronic device coupled to a particular AV port is a source device or a sink device. Based on that determination, switching device 104 may configure that AV port to be a source AV port or a sink AV port. Additional details regarding the auto-configuration of AV ports 110A-110D is described below in Subsection A.
Switching device 104 may also be configured to automatically identify (e.g., determine) the electronic device coupled to each of AV ports 110A-110D. For example, for each electronic device coupled to a particular AV port, switching device 104 may be configured to determine one or more identifiers of the electronic device, such as, but not limited to, a type of the electronic device (e.g., a DVD player, a Blu-ray player, a video game console, a streaming media device, a TV, an HDTV, a projector, etc.), a brand name of the electronic device, a manufacturer of the electronic device, a model number of the electronic device, etc. The identifier(s) may be determined according to various techniques, such as, but not limited to: techniques based on HDMI consumer electronics control (CEC), identification via video data, identification via audio data, identification via IP network, remote control operation by a user, voice input from a user, and explicit device selection by a user. Upon determining the identifier(s), switching device 104 may be configured to map the identified electronic device to the AV port to which that electronic device is connected. This process may be referred to as “device-to-port mapping.” Additional details regarding device-to-port mapping is described below in Subsection B.
Switching device 104 may be further configured to automatically select or switch between AV ports 110A-110C based on determining which electronic device(s) a user would like to use for providing and/or presenting content. For example, in accordance with an embodiment, switching device 104 is configured to automatically select one or more of AV port(s) 110A-110C based on determining that an RF remote control device is being used. For instance, if a user would like to view content from electronic device 102B (e.g., a STB), the user may interact with an RF remote control device associated with electronic device 102B. Upon the user's interaction with the RF remote control device, the remote control device may transmit an RF signal to electronic device 102B, as well as a non-RF signal that is received by switching device 104. Upon receipt of the RF or non-RF signal, switching device 104 determines that the RF remote control device associated with electronic device 102B is being used. Once this determination is made, switching device 104 may determine which AV port is coupled to electronic device 102B using the device-to-port mapping described above. After determining that electronic device 102B is connected to AV port 110B, switching device 104 may automatically select (or switch to) AV port 110B, thereby enabling electronic device 110B to provide audio and/or video signals 108B to electronic device 102D for playback. Additional details regarding automatically selecting an AV port based on determining that an RF remote control device is being used are described below in Subsection C.1.
In accordance with another embodiment, switching device 104 may be configured to automatically control one or more source devices, and one or more sink devices. For example, when a user is using an RF remote control device associated with an electronic device (e.g., electronic device 102B), switching device 104 may detect an RF or non-RF signal transmitted by the RF remote control device and thereby determine that the RF control device is being used. Upon making the determination that an RF remote control device associated with electronic device 102B is being used, switching device 104 may transmit a control signal to one or more source devices or one or more sink devices coupled to switching device 104. For instance, if switching device 104 determines that an RF control device associated with electronic device 102B is being used, switching device 104 may transmit a signal to power off electronic devices 102A and/or 102C. Switching device 104 may also determine that one or more sink devices are associated with electronic device 102B, and transmit a signal to power on each of the associated sink device(s) (e.g., electronic device 102D). Additional details regarding automatically controlling one or more source or sink devices based on an RF remote control detection are described below in Subsection C.2.
In accordance with another embodiment, switching device 104 may be configured to automatically control one or more other devices that are not source or sink devices. For instance, when a user is using an RF remote control device associated with an electronic device (e.g., electronic device 102B), switching device may detect an RF or non-RF signal transmitted by the RF remote control device and thereby determine that the RF control device is being used. Upon making the determination that an RF remote control device associated with electronic device 102B is being used, switching device 104 may transmit a control signal to one or more other devices that are not source devices or sink devices. For instance, if switching device 104 determines that an RF control device associated with electronic device 102B is being used, switching device 104 may determine that one or more other devices (e.g., such as an electronic device or a home automation device) should automatically be controlled in response. Additional details regarding automatically controlling one or more devices that is not a source or sink device based on an RF remote control detection are described below in Subsection C.3.
Control device(s) 106 may be operable to control any or all of electronic devices 102A-102D and/or switching device 104. Control device(s) 106 may include a display screen and/or one or more physical interface elements (e.g., buttons, sliders, jog shuttles, etc.). In accordance with an embodiment, the display screen (or a portion thereof) may be a capacitive touch display screen. The display screen may be configured to display one or more virtual interface elements (e.g., icons, buttons, search boxes, etc.). The display screen may be configured to enable a user to interact, view, search, and/or select content for viewing via any of electronic device 102A-102D and switching device 104. In embodiments, control device(s) 106 may be configured to transmit both an RF signal and a non-RF signal upon a user interaction with the control device(s). For example, the RF signal may be transmitted to any of electronic devices 102A-102D, and the non-RF signal may be transmitted to switching device 104. By transmitting the non-RF signal in addition to the RF signal, switching device 104 may determine when any one of control device(s) 106 are being used to control electronic device(s) 102A-102D. Additional details regarding one exemplary implementation of control device 106 are provided below in reference to
In accordance with an embodiment, control device(s) 106 may be operable to control any or all of electronic devices 102A-102D by transmitting control signals thereto. In embodiments, the RF signal may be transmitted via any suitable type of RF communication (e.g., Bluetooth™, as described in the various standards developed and licensed by the Bluetooth™ Special Interest Group, technologies such as ZigBee® that are based on the IEEE 802.15.4 standard for wireless personal area networks, near field communication (NFC), other RF-based or internet protocol (IP)-based communication technologies such as any of the well-known IEEE 802.11 protocols, etc.), and/or the like. In accordance with an embodiment, the non-RF signal may comprise, for example, an IR signal utilizing an IR protocol.
A. Automatic Configuration of AV Ports
Connector scheme 258 includes one or more AV ports 210 (also referred to as AV connectors). In accordance with an embodiment, AV port(s) 210 are configured to accept HDMI connections from HDMI enabled devices, such as HDMI sink devices and HDMI source devices. According to embodiments, any AV port of AV port(s) 210 may accept a sink device or a source device. While not shown for illustrative clarity, a typical signal conditioning scheme may also be retained to meet the strict compliance requirements for the standard used to implement AV port(s) 210 (e.g., an HDMI standard in an embodiment where AV port(s) 210 are HDMI AV port(s)).
Configuration scheme 250 includes a transceiver 240 that includes an input component RX 242 and an output component TX 244. Transceiver 240 is configured to receive audio and/or video signals at input component RX 242 and to transmit audio and/or video signals from output component TX 244. In other words, transceiver 240 provides received input audio and/or video signals from source devices as output audio and/or video signals to sink devices, in accordance with the embodiments herein. It is also contemplated herein that one or more of input component RX 242 and/or an output component TX 244 may be included in transceiver 240 in various embodiments.
Detection scheme 256 may include one or more detectors 232 that are configured to detect indicia of operational modes to determine a type of an electronic device (e.g., an HDMI-enabled device) connected to AV port(s) 210 (i.e., whether the electronic device is a source or a sink). In embodiments, detectors 232 may be configured to make such a detection/determination based on signals received from AV port(s) 210.
Control scheme 254 may include control logic 220 that is configured to receive the detected indicia or signals based thereon from detectors 232 and use the received information to control one or more aspects of switching scheme 252, such as one or more switches included therein.
Switching scheme 252 includes switch circuit 214. Switch circuit 214 may be configured to provide switched connections between AV port(s) 210 and transceiver 240. That is, switch circuit 214 may provide a connection between any AV port of AV port(s) 210 and any receiver (e.g., input component RX 242) or transmitter (e.g., output component TX 244) of transceiver 240. Switch circuit 214 may comprise one or more switch circuit portions and may be combined or used in conjunction with other sub-schemes of switching device 204.
Accordingly, there is no need to pre-define the function of any port of AV port(s) 210. That is, AV port(s) 210 can be configured either as inputs or outputs. Additionally, detector(s) 232 are configured to detect the type of electronic device (i.e., a source device or a sink device) connected to an AV port of AV port(s) 210 and provide this information as input to control scheme 254, which may then issue appropriate commands to switch circuit 214 to either connect to input component RX 242 or output component TX 244 of transceiver 240. Thus, the same AV port can act as an input or an output depending on which type of electronic device is connected and considerably enhance the convenience of an interface process of switching device 204 (e.g., a process in which a user connects electronic device(s) to AV port(s) 210 of switching device 204).
Accordingly, the techniques and embodiments described herein provide for improvements in auto-detection and adaptive configuration of AV port(s), as described above. Additional details regarding the auto-configuration of AV port(s) may be found in U.S. patent application Ser. No. 14/945,079, filed on Nov. 18, 2015 and entitled “Auto Detection and Adaptive Configuration of HDMI Ports,” the entirety of which is incorporated by reference.
B. Automatic Port Mapping to Connected Devices
Switching device 304 may be an example of switching device 104 or switching device 204, as described above in reference to
Transceiver 340 may be an example of transceiver 240 as described above in reference to
Identification component 338 may be configured to identify the electronic device (e.g., electronic device(s) 302A or 302B) coupled to each AV port of AV port(s) 310. For example, for each electronic device(s) 302A or 302B, identification component 338 may be configured to determine identifier(s) of the electronic device, such as, but not limited to a type of the electronic device (e.g., a DVD player, a Blu-ray player, a video game console, a streaming media device, a TV, an HDTV, a projector, etc.), a brand name of the electronic device, a manufacturer of the electronic device, a model number of the electronic device, etc. The identifier(s) may be determined according to various techniques, such as, but not limited to: techniques based on HDMI consumer electronics control (CEC), identification via video data, identification via audio data, identification via IP network, remote control operation by a user, voice input from a user, and explicit device selection by a user. Identification component 338 provides the identifier(s) to mapping component 318.
Mapping component 318 is configured to determine a device-to-port mapping based on the identifier(s) received from identification component 338. For example, mapping component 318 may generate a data structure (e.g., a table) that associates the identifier(s) for any given identified electronic device to the AV port to which that electronic device is coupled. In this way, the device-to-port mapping may indicate that a first electronic device (e.g., a Blu-ray player) is coupled to a first AV port (e.g., AV Port 1), that a second electronic device (e.g., a STB) is coupled to a second AV port (e.g., AV Port 2), and that a third electronic device (e.g., a TV) is coupled to a third AV port (e.g., AV Port 3).
Additional details regarding the identification of electronic device(s) and the mapping of electronic device(s) to AV port(s) may be found in U.S. patent application Ser. No. 14/945,125, filed on Nov. 18, 2015 and entitled “Automatic Identification and Mapping of Consumer Electronic Devices to Ports on an HDMI Switch,” the entirety of which is incorporated by reference.
Control logic 320 may be an example of control logic 220 as described above in reference to
C. Remote Control Activity Detection
In the illustrative example shown in
Switching device 404 may be an example of switching device 104, switching device 204 or switching device 304, as described above in reference to
Switch circuit 414 may be an example of switch circuit 214 as described above in reference to
For example, control device 422 may be a RF remote control device that is configured to operate any one of electronic devices 402A-402E, and control device 424 may be an RF remote control device that is configured to operate another one of electronic device 402A-402E. Each of control device 422 and 424 may be configured to operate a particular electronic device by transmitting a control signal to that electronic device via a wireless connection (e.g., an RF communication). For illustrative purposes, control device 422 is configured to operate electronic device 402A and, thus, is shown transmitting an RF control signal 426A to electronic device 402A, and control device 424 is configured to operate electronic device 402B, and thus is shown transmitting an RF control signal 428A to electronic device 402B. It is noted that system 400 may comprise additional remote control device(s) that are operable to control other electronic device(s) (e.g., electronic device 402C, electronic device 402D, or electronic device 402E). In another embodiment, control device 422 or control device 424 may be a universal remote control that may be configured to operate a plurality of electronic devices 402A-402E, and/or any other electronic device, such as switching device 404.
Each of control device 422 and 424 may also be configured to transmit a non-RF signal control signal 426B and 428B, respectively, in addition to RF control signal 426A and RF control signal 428A. Examples of such remote controls may include, for example, remote controls commonly provided with set-top boxes (STBs), AppleTV™ remote and Universal Remote controllers that are configured to transmit both an RF and a non-RF signal. An RF remote control (e.g. control device 424) may provide remote control of devices (e.g. STB 402B) via an RF signal and control of other devices (e.g. TV 402D) via non-RF (e.g. IR) signals, which may be user-programmable.
User interface 506 may comprise any suitable user interface, including a physical user interface, graphical user interface, voice-based user interface, or the like. For instance, user interface 506 may comprise physical interface elements, such as, but no limited to, a power button, a volume up button, a volume down button, number keys, and/or letter keys. User interface 506 may also comprise a capacitive touch display screen comprising one or more interface elements (e.g., icons, buttons, etc.). One or more of the user interface elements on user interface 506 may be activated when pressed (e.g., such interface elements may be click-sensitive), rather than simply being touched. This advantageously enables control device 502 to unambiguously determine that a user intended to activate such interface element(s) instead of accidentally touching such interface element(s). In accordance with one or more embodiments, one or more of interface elements may provide tactile feedback when activated. Actuation of any one of the user interface elements via user interface 506 may cause control device 502 to transmit an RF signal operable to control a first device via RF-transmitter 504B, and/or a non-RF signal via non-RF transmitter 504B.
Referring back to
It may be advantageous to know whether a user is using a remote control (e.g. control device 422 or control device 424) to control a device, such as electronic device 402A or electronic device 402B. This knowledge may be used, for example, to perform one or more actions, such as coupling a source device to one or more sink devices, controlling one or more source or sink devices, or controlling any other electronic device that is not a source or sink device. For instance, when control device 424 is being used, it may be desired to automatically connect electronic device 402B (e.g., a STB) to electronic device 402D (e.g., a TV), such that electronic device 402D displays audio-visual information provided by electronic device 402B.
It may be difficult for switching device 404 to detect a transmission of RF signals 426A or 428A by control device 422 or control device 424, for example, when the control devices are used to control electronic device 402A or electronic device 402B. Accordingly, receiver 430 of switching device 404 may be configured to detect non-RF signals to determine when control device 422 or control device 424 is being used. Use of RF-based remote controls may be detected, for example, by detecting non-RF signals (e.g. IR signals) also transmitted by the RF remote control device.
Remote controls, e.g., including control device 422 and control device 424, may be configured to set specific makes and/or models of devices (e.g. TVs), for example, to select one or more non-RF control signals (e.g. IR signals) from remote controls to control particular devices (e.g. TVs). In an example, a user may indicate a make and/or model of a TV or other device when programming an RF remote control device capable of also transmitting a non-RF signal. The RF remote control device may look up a database of IR codes and may select one or more specific IR codes for the make and/or model of the TV entered by the user.
In another embodiment, the one or more specific IR codes may be programmed automatically by switching device 404, for example, through user interface logic 442 and one or more source devices (e.g., electronic device 402D or 402E). For instance, a user may select a specific make and/or model of a device to program the non-RF signal of one of control devices 422 or 424. In such an embodiment, switching device 404 may automatically transmit a device identification code to program the RF remote control device through any suitable communication method, including a wireless transmission (e.g., an RF transmission or IR transmission), or a wired transmission.
In an example, a TV type for a programmable RF remote control may be programmed to a known but rarely used TV type. For instance, control device 422 or 424 may be programmed to control a make/model of a TV that is not the same make/model of the TV (or any other source or sink device) coupled to switching device 404. In this manner, the non-RF signal does not directly control any source or sink device in system 400, but rather transmits a non-RF signal that contains a device identification code (e.g., for a known but rarely used TV type) that indicates to switching device 404 that the non-RF signal should not be ignored by the switching device. By purposely programming the RF remote control device (e.g., control device 422 or 424) with a device identification code corresponding to a known but rarely used TV type that is not intended to be ignored by switching device 404, switching device 404 can thereby detect when the RF remote control device is being used.
In an embodiment, control device 422 or 424 may be configured to permit a user to select the particular device identification code for which the non-RF signals of control device 422 or 424 are programmed. In this embodiment, control logic 420 may also be configured to detect non-RF signals containing the user-selected device identification code. In another embodiment, control logic 420 may be configured to detect and act on only certain predetermined device identification codes. In such an embodiment, user interface logic 442 may prompt a user to program control device 422 or 424 with one of the predetermined device identification codes, such that control logic 420, upon receiving the non-RF signal, does not ignore the non-RF signal.
In another embodiment, switching device 404 may automatically program control device 422 or 424 with a device identification code. In yet another embodiment, control device 422 or 424 may be programmed with a predetermined device identification code (e.g., from a factory, manufacturer, or retailer). In this illustrative scenario, control logic 420 may be programmed with the device identification code corresponding to control device 422 or 424, such that non-RF signals transmitted by control device 422 or 424 to receiver 430 are not ignored. In yet another embodiment, control device 422 or 424 may come preprogrammed with a device identification code corresponding to a known but rarely used TV type (or any other device identification code) for which switching device 404 is preprogrammed. In this manner, switching device 404 may already be configured not to ignore non-RF signals transmitted by control device 422 or 424, eliminating the need for additional programming.
Thus, a device identification code, such as an IR code, associated with the non-RF signals of control device 422 or 424 may be known and detectable by control logic 420. By detecting a non-RF signal comprising a known device identification code (e.g., a pre-programmed IR code), control logic 420 can automatically determine when a particular RF remote control device (e.g., a remote control associated with a STB) is being used.
In this manner, upon detecting that a particular RF remote control device is being used, switching device 404 may automatically take any one of a number of actions in response, such as controlling a port switching operation within switching device 404, controlling a source device, controlling a sink device, or controlling any other electronic device, as will be described in greater detail below.
In another embodiment, a user may, either unilaterally or when prompted through user interface logic 442, program the RF remote to transmit a non-RF signal comprising a device identification code that an electronic device (e.g., TV 402D) connected to switching device 404 does not ignore, as opposed to a device identification code corresponding to a known but rarely used TV type that the electronic device is expected to ignore. In this illustrative scenario, a smart HDMI switch (e.g., switching device 404) may nevertheless be configured not to ignore the non-RF signals. However, because the electronic device (e.g., TV 402D) is configured to act upon non-RF signals received by it, the smart HDMI switch need not transmit a control signal to the electronic device comprising a same instruction received by the electronic device via the non-RF signal. Rather, upon detection of the non-RF signal comprising the device identification code, the smart HDMI switch may perform additional non-conflicting functions, such as controlling a port switching operation within switching device 404, controlling a source device, controlling additional functions of a sink device, controlling a separate sink device, or controlling any other electronic device.
Accordingly, a switch may (e.g. based on user set up in response to prompting) or otherwise (e.g. based on knowledge of devices coupled to the switch) detect any non-RF signals that a user may setup for the RF remote to determine when the user is using the RF remote. Regardless how a switch and RF remote control device are made aware of the particular device identification code to use for the non-IR transmission indicating that the RF remote control device is being used, control logic 420 may detect the non-RF signal and switching device 404 may use the detection to react accordingly, such as by controlling power to one or more other devices (e.g. TV) and/or switching audio and/or visual (e.g. HDMI) inputs and/or outputs.
For instance, in an embodiment comprising a smart switch (e.g., switching device 404), the switch may be aware of which one or more devices an RF controller controls based on the detection of the non-RF signal. The switch may decide (e.g., based on a static and/or dynamic configuration provided by a manufacturer, user or device algorithm) to perform one or more operations upon detecting that a user is using an RF remote, such as switching the switch to particular source port (e.g., port 410B corresponding to STB 402B) upon detecting a user is using an RF remote to control an STB. The switch may also perform other operations, such as turning a TV on to display the output of the STB or other TV-related operations, such as changing a video or audio setting of the TV.
Mapping component 418 may be an example of mapping component 318 as described above in reference to
Control logic 420 may be an example of control logic 220 as described above in reference to
Accordingly, in embodiments, automatically performing an action may be carried out upon determining that a particular RF remote control device is being used in many ways. For instance,
Flowchart 600 begins with step 602. At step 602, a non-RF signal transmitted by an RF remote control device operable to control a first device is detected. For example, with reference to
In step 604, a determination is made that the RF remote control device is in use in response to the detection of the non-RF signal. For instance, with continued reference to
Control logic 420 is not limited to the above illustrative examples. Control logic 420 may be programmed not to ignore a plurality of device identification codes. For instance, where a system comprises a plurality control devices 422 and 424, each control device 422 and 424 may be programmed with a different device identification code. For example, control device 422 may be programmed to transmit non-RF signal 426B corresponding to a particular known but rarely used TV type, while control device 424 may be programmed to transmit non-RF signal 428B corresponding to a different known, but rarely used TV type. In this example, control logic 420 may be configured not to ignore either device identification codes. In this manner, when receiver 430 receives either non-RF signal 426B or 428B, control logic 420 may automatically determine which particular control device is being used based on the device identification code and mapping component 418, thereby also permitting control logic to determine which particular source device is being used.
In step 606, in response to determining that the RF remote control device is in use, at least one action is performed. For example, with reference to
In yet another embodiment, control logic 420 may control any combination of the exemplary actions discussed above. For instance, upon determining that control device 422 associated with electronic device 402B (e.g., a STB) is being used, control logic 420 may cause transmitter 432 to transmit a control signal 434 to electronic device 402D (e.g., a TV) instructing electronic device 402D to power on. In addition, control logic 420 may also cause switch circuit 414 to connect electronic device 402B and electronic device 402D, such that content from electronic device 402B (e.g., a STB) is displayed on electronic device 402D (e.g., a TV).
In another example, switching device 404 may be configured to display content from a particular source device (e.g., a STB) on a plurality of sink devices (e.g., a TV and a projector). In this example, upon detection that a control device 424 associated with electronic device 402B is being used, control logic 420 may cause transmitter 432 to transmit control signal 434 to electronic device 402D (e.g., a TV), as well as a control signal 436 to electronic device 402E (e.g., a projector), causing both electronic devices 402D-402E to be powered on. Control logic 420 may also perform any number of actions in response to a determination that a particular RF remote control is being used, and is not limited to the illustrative examples described herein.
In some example embodiments, one or more of operations 602, 604, and/or 606 of flowchart 600 may not be performed. Moreover, operations in addition to or in lieu of operations 602, 604, and/or 606 may be performed. Further, in some example embodiments, one or more of operations 602, 604, and/or 606 may be performed out of order, in an alternate sequence, or partially (or completely) concurrently with each other or with other operations
1. Automatic Port Selection Based on Determining that a Particular RF Remote Control Device is Being Used
In accordance with embodiments disclosed herein, automatic port selection may be performed based on determining that a particular RF remote control device is being used in many ways. For instance,
Flowchart 700 begins with step 702. At step 702, a determination is made that a receiver has received a non-RF signal transmitted by an RF remote control device that is operable to control a first device. For example, with reference to
In step 704, a determination is made that the RF remote control device is in use in response to the detection of the non-RF signal. In an embodiment, step 704 of
In step 706, a source device that is associated with the remote control device is identified from among the one or more source devices. For example, with reference to
In step 708, a first AV port from among the plurality of AV ports to which the identified source device is connected is identified. For example, with reference to
In step 710, the first AV port is automatically connected to the one or more AV ports to which one or more sink device are connected so that content can be provided from the identified source device to the one or more sink devices. For example, with reference to
Embodiments, however, are not limited to presenting content on a single source device. For instance, switching device 404 may be configured to associate a particular source device with more than one sink device, such that content from the source device may be presented on more than one display. In an embodiment, for example, if the first AV port is identified to be AV port 410A, and electronic device 402D (e.g., a TV) and electronic device 402E (e.g., a projector) are both associated with the presentation of content from the first electronic device, then switch circuit 414 may automatically connect AV port 410A to AV ports 410D and 410E.
In some example embodiments, one or more of operations 702, 704, 706, 708, and/or 710 of flowchart 700 may not be performed. Moreover, operations in addition to or in lieu of operations 702, 704, 706, 708, and/or 710 may be performed. Further, in some example embodiments, one or more of operations 702, 704, 706, 708, and/or 710 may be performed out of order, in an alternate sequence, or partially (or completely) concurrently with each other or with other operations.
In accordance with an embodiment, switching device 404 may be further configured to automatically switch from the first AV port to a second AV port. For instance,
Flowchart 800 begins with step 802. At step 802, a determination is made that a receiver has received a second non-RF signal transmitted by a second RF remote control device that is operable to control a second device. In an embodiment, step 802 of
In step 804, a determination is made that the second RF remote control device is in use in response to the detection of the second non-RF signal. In an embodiment, step 804 of
In step 806, a source device that is associated with the second remote control device is identified from among the one or more source devices. In an embodiment, step 806 of
In step 808, a second AV port from among the plurality of AV ports to which the identified second source device is connected is identified. For example, with reference to
In step 810, the second AV port is automatically connected to the one or more AV ports to which one or more sink device are connected so that content can be provided from the identified second source device to the one or more sink devices. For example, with reference to
In some example embodiments, one or more of operations 802, 804, 806, 808, and/or 810 of flowchart 800 may not be performed. Moreover, operations in addition to or in lieu of operations 802, 804, 806, 808, and/or 810 may be performed. Further, in some example embodiments, one or more of operations 802, 804, 806, 808, and/or 810 may be performed out of order, in an alternate sequence, or partially (or completely) concurrently with each other or with other operations.
2. Automatic Control of a Source or Sink Device
In accordance with embodiments disclosed herein, one or more source or sink devices may be controlled upon determining that an RF remote control device is being used in many ways. For instance,
Flowchart 900 begins with step 902. In step 902, in response to a determination that a particular RF remote control device is in use, one of the one or more source devices or one of the one or more sink devices coupled to a switching device is automatically controlled. For instance, with reference to
In response control logic 420 determining that a particular RF remote control device is being used, control logic 420 may cause transmitter 432 to transmit a control signal to any one or more of source devices 402A-402C, or sink devices 402D-402E. As an example, upon detection of non-RF signal 428B, control logic 420 may determine that control device 424 is being used. Based on that determination, control logic 420, using mapping component 418, may automatically determine that a user is intending to view audio/video content from electronic device 402B, which is coupled to port 410B, on one or more designated sink devices. In this example, control logic 420 may cause transmitter 432 to transmit a control signal (not shown) to electronic device 402B connected to the identified source AV port to power on the device, and/or a separate control signal 434 or 436 to the one or more associated sink devices connected to the identified sink AV ports that causes the sink devices to be powered on.
In another embodiment, switching device 404 may be configured to manage the state of one or more electronic devices 402A-402E. For example, control logic 420 may cause transmitter 432 to transmit a control signal causing any non-used source and/or sink devices to be powered off based on a determination that a particular RF remote control device is being used. In an embodiment, when a remote control device associated with electronic device 402B (e.g., a STB) is being used, transmitter 432 may transmit one or more control signals to all other non-used source devices instructing the non-used source devices to be powered off. Similarly, transmitter 432 may automatically transmit a control signal 434 or 436 to any non-used sink devices instructing the non-used sink devices to be powered off. In this manner, because switching device 404 may be configured to manage the state of all source or sink devices, a user need not operate additional remote controls to manage the state of non-used source or sink devices.
In order to avoid a source or sink device from also acting on non-RF signals transmitted by control device 422 or 424, control device 422 or 424 may be programmed to transmit a non-RF signal comprising device identification codes that the source or sink devices are expected to ignore. For instance, where a system comprises a plurality control devices 422 and 424, each control device 422 and 424 may be programmed with a different device identification code. Mapping component 418 may associate each device identification code with a particular remote control device and/or source device. For example, control device 422 may be programmed to transmit non-RF signal 426B corresponding to a particular known but rarely used TV type, while control device 424 may be programmed to transmit non-RF signal 428B corresponding to a different known, but rarely used TV type. In this example, control logic 420 may be configured not to ignore either device identification codes. In this manner, when receiver 430 receives either non-RF signal 426B or 428B, control logic 420 may automatically determine which particular control device is being used based on the device identification code and mapping component 418. Based on the determination, control logic 420 may appropriately manage the state of one or more source devices or sink devices. In addition, because control devices 422 and 424 may be programmed to transmit non-RF signals comprising device identification codes corresponding to known but rarely used TV types, each of the source devices or sink devices coupled to switching device 404 may ignore the non-RF signals, thereby permitting switching device 404 full management of the state of the source or sink devices.
In accordance with embodiments, however, it is not necessary to program one or more of control devices 422 or 424 with device identification codes corresponding to known but rarely used TV types. Rather, control devices 422 or 424 may be programmed with any other device identification code that the source or sink devices are known to ignore. For instance, a smart HDMI switch (e.g., switching device 404) may automatically detect a type of TV (e.g. among other devices) that may be connected to the switch. Based on this detection, switching device may prompt a user, through user interface logic 442, to program an RF remote control device with a device identification code that the detected TV will ignore. In this manner, the smart HDMI switch can ensure that a non-conflicting device identification code is programmed into the RF remote control device, thereby minimizing the possibility that a source or sink device takes any action in response to non-RF signals transmitted by the RF remote control device.
As discussed above, however, control devices 422 or 424 may be programmed to transmit a non-RF signal comprising a device identification code that a source device or sink device coupled to switching device 404 does not ignore. In this illustrative scenario, a smart HDMI switch (e.g., switching device 404) may nevertheless be configured not to ignore the non-RF signals comprising the same device identification code. However, because the electronic device (e.g., TV 402D) is configured to act upon non-RF signals received by it, the smart HDMI switch need not transmit a control signal to the electronic device comprising the same instruction already received by the electronic device. Rather, upon detection of the non-RF signal comprising the device identification code, the smart HDMI switch may perform additional non-conflicting functions, such as controlling a port switching operation within switching device 404, controlling a source device, controlling additional functions of a sink device, controlling a separate sink device, or controlling any other electronic device.
In accordance with another embodiment, switching device 404 may determine a current power state of the source and/or sink device, for example by analyzing audio and/or video signals to/from the port connected to the source or sink device. In this event, switching device 404 may be determine whether the source and/or sink device is already powered on. In this manner, switching device 404 may avoid transmitting an unnecessary control signal to a source or sink device. If switching device 404 determines that the source device and/or sink device are not powered on upon determining that a particular RF remote control is being used, switching device 404 may provide a control signal 434 or control signal 436 to power on the device. Additional details regarding how the power state of an electronic device is determined may be found in U.S. patent application Ser. No. 14/945,201, filed on Nov. 18, 2015 and entitled “Automatic Detection of a Power Status of an Electronic Device and Control Schemes Based Thereon,” the entirety of which is incorporated by reference.
Control of a source or sink device is not limited to the above examples in which a source or sink device is powered on or powered off upon determining that a particular RF remote control is being used. In accordance with other embodiments, control logic 420 may cause transmitter 432 to transmit any type of control signal to any one of a source or sink device. For instance, transmitter 432 may automatically transmit a control signal causing a change to an audio or video setting of a source or sink device. For instance, a control signal may instruct a source or sink device to change a video resolution. As another example, a control signal may instruct a source device to output an audio signal to a separate surround sound system instead of to a source device coupled to switching device 404. In another embodiment, transmitter 432 may automatically transmit a control signal causing a source or sink device to change a graphics mode (e.g., changing a sink device from a “movie” mode to a “game” mode) upon determining that a particular RF remote control device is being used. These examples are merely provided for illustrative purposes. In embodiments, a control signal may include any type of signal that causes a change in a state or setting of any one of a source or sink device upon determining that a particular RF remote control device is in use.
In embodiments, control signal 434 or 436 may be transmitted via any suitable type of RF communication (e.g., Bluetooth™, as described in the various standards developed and licensed by the Bluetooth™ Special Interest Group, technologies such as ZigBee® that are based on the IEEE 802.15.4 standard for wireless personal area networks, near field communication (NFC), other RF-based or internet protocol (IP)-based communication technologies such as any of the well-known IEEE 802.11 protocols, etc.), and/or the like. In another embodiment, control signal 434 or 436 may be transmitted via a wired connection (e.g., via a Universal Serial Bus (USB) cable, a coaxial cable, IP-based communication technologies, etc.) or transmitted via a wireless connection (e.g., via IR communication) and/or the like.
3. Automatic Control of a Device that is Not a Source or Sink Device
In accordance with embodiments disclosed herein, one or more additional devices that are not source or sink devices may be automatically controlled upon determining that an RF remote control device is being used in many ways. For instance,
Flowchart 1000 begins with step 1002. In step 1002, in response to a determination that a particular RF remote control device is in use, one or more devices that is not a source or sink device of the switching device may be automatically controlled. For instance, with reference to
In response control logic 420 determining that a particular RF remote control device is being used, control logic 420 may cause transmitter 432 to transmit a control signal 438 to an electronic device(s) 440 that is not one of the source devices or sink devices connected to the switching device 404. For instance, control logic 420 may be programmed to associate a particular source device (e.g., electronic device 402A which may be a Blu-ray player) with a predetermined viewing atmosphere (e.g., a low-light atmosphere). Accordingly, upon detection of non-RF signal 426B transmitted by control device 422, which is associated with electronic device 402A, control logic 420 may automatically control one or more additional devices, such as a light and/or a window shade. In this manner, a user interacting with a remote associated with a Blu-ray player need not manually operate any of the additional electronic devices.
In another embodiment, control signal 438 may comprise a signal to automatically control projection screen associated with a particular sink device (e.g., electronic device 402E). For instance, if switching device 404 is configured to cause a particular source device (e.g., electronic device 402A) to provide content to a projector (e.g., electronic device 402E), control signal 438 may transmit a signal to a motorized projection screen causing the screen to be lowered upon detection that an RF remote control device associated with electronic device 402A is being used.
In another embodiment, control signal 438 may comprise a signal to automatically control a thermostat upon detection that a particular RF remote control device is being used. For instance, a thermostat may be controlled to automatically lower or raise a temperature upon control logic 420 determining that a particular remote control device is in use.
In yet another embodiment, control signal 438 may comprise a signal to automatically control one or more functions of a smart phone or other portable electronic device. For example, upon determining that a particular RF remote control device is being used, control logic 420 may cause transmitter 432 to emit control signal 438 causing a smartphone to change a ringer setting. For instance, a smart phone may be automatically controlled to operate in a reduced volume or silenced mode. In another embodiment, a smart phone may be automatically controlled to operate in a “do-not-disturb” mode. These examples, however, are only illustrative. Any other feature or function of a smart phone may be automatically controlled upon determining that a particular remote control device is being used.
In yet another embodiment, control signal 438 may comprise a signal to automatically control an audio system, such as a surround sound system, based on a determination that a particular RF remote control device is being used. For instance, control logic 420 may be configured to automatically cause transmitter 432 to transmit a control signal 438 causing a surround sound system to be powered on, powered off, raise or lower a volume, and/or change a surround sound mode.
In embodiments, control signal 438 may be transmitted via any suitable type of RF communication, wired connection, or wireless connection, in a similar manner as described above with reference to
