[0002] Currently, when a user uses multiple projection devices, each projection device can be controlled by a Bluetooth remote control device corresponding to each projection device. However, with this method, it is necessary to equip each of the multiple projection devices with a corresponding Bluetooth remote control device, which results in an increasing number of Bluetooth remote control devices that are difficult to manage. In addition, there is a problem that users easily forget the Bluetooth remote control device corresponding to each projection device, which affects the user experience.

[0003] In order to solve the above-mentioned problem of multiple remote control devices, in the prior art, multiple projection devices can be controlled by one infrared remote control device. Specifically, multiple projection devices within the transmission range of the infrared signal emitted by the infrared remote control device can receive the control signal of the infrared remote control device, thereby realizing the control of the multiple projection devices. However, when the infrared remote control device is used to control the multiple projection devices, it is impossible to clearly know which projection device the control signal currently emitted by the infrared remote control device is specifically targeted at. As a result, the multiple projection devices within the infrared signal transmission range all respond when they receive the control signal at the same time, thereby causing mutual influence between the multiple projection devices.

[0045] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0047] The terms "first" and "second" in this disclosure are used to distinguish different objects rather than to describe a specific order of objects. For example, a first processing result and a second processing result are used to distinguish different processing results rather than to describe a specific order of processing results.

[0048] Figure 1A A schematic diagram of an application scenario of a multi-projection device provided in an embodiment of the present disclosure, such as Figure 1A As shown, for example, for multiple projection devices 200, the user can control them through the Bluetooth remote control device 100 corresponding to each projection device 200. However, with this method, since each projection device 200 is equipped with a corresponding Bluetooth remote control device 100, an increasing number of Bluetooth remote control devices 100 are difficult to manage, and there is a problem that the user easily forgets the Bluetooth remote control device 100 corresponding to each projection device 200, which affects the user experience.

[0049] Based on this, in order to solve the above-mentioned problem of multiple Bluetooth remote control devices 100, Figure 1B A schematic diagram of another application scenario of a multi-projection device provided in an embodiment of the present disclosure, such as Figure 1B As shown, a user can control multiple projection devices 200 through an infrared remote control device 300. Specifically, since multiple projection devices 200 within the infrared signal transmission range emitted by the infrared remote control device 300 can receive the control signal of the infrared remote control device, multiple projection devices 200 can be controlled by using one infrared remote control device 300.

[0050] However, in the process of using an infrared remote control device 300 to control multiple projection devices 200, it is impossible to clearly know which of the multiple projection devices 200 the control signal emitted by the infrared remote control device 300 is specifically directed to, resulting in multiple projection devices, when receiving the control signal at the same time, all respond, thereby causing mutual influence between the multiple projection devices. For example, when multiple projection devices such as projection device 1, projection device 2, and projection device 3 are working, it is necessary to send a brightness control signal through the infrared remote control device 300 to adjust the brightness of projection device 2, but projection device 1 and projection device 3 can also receive the brightness control signal and respond to the brightness control signal, thus causing the problem of mutual influence between the multiple projection devices when controlling any one of projection device 1, projection device 2, and projection device 3.

[0051] In order to solve the above problems, the embodiment of the present disclosure proposes a multi-projection device control method, which is applied to a multi-projection device control system. The multi-projection device control system includes multiple projection devices, and the multiple projection devices are communicatively connected with each other. An arbitrator is arranged on each projection device, and the arbitrator of each projection device can respond to a joint control signal, generate a target random number corresponding to each projection device, and send the target random number to other projection devices, wherein the joint control signal is used to instruct each projection device to receive control of the control signal of the same infrared control device; through the arbitrator of each projection device, according to multiple target random numbers, determine the response order of the multiple projection devices in responding to the control signal sent by the infrared control device; receive the control signal sent by the infrared control device, and respond to the control signal according to the response order. In the above technical solution, after receiving the joint control signal, multiple projection devices can generate a target random number through the arbitrator set therein and send it to other projection devices, so that the projection devices can determine the response order of responding to the control signal sent by the infrared control device according to the target random numbers corresponding to the multiple projection devices respectively, so that the projection devices can respond to the control signal in sequence according to the response order, avoiding the problem in the prior art that multiple projection devices all respond when receiving the control signal at the same time, causing mutual influence between the multiple projection devices.

[0052] In some embodiments, the control device 100 is an infrared remote control device such as an infrared remote controller, and the infrared remote control device communicates with the projection device through an infrared protocol to control the projection device 200. The user can input user commands through the keys on the infrared remote controller to control the projection device 200. For example, the user can input corresponding control commands through the volume plus and minus keys, menu keys, power on and off keys, etc. on the infrared remote controller to realize the function of controlling the projection device 200.

[0053] Figure 2 FIG. 2 is a block diagram of a hardware configuration of a projection device 200 according to one or more embodiments of the present disclosure. Figure 2The projection device 200 shown includes at least one of a tuner 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface (i.e., a user input interface) 280. The controller 250 includes a central processing unit, a video processor, an audio processor, a graphics processor, a RAM, a ROM, and a first interface to an nth interface for input / output. The display 260 can be at least one of a liquid crystal display, an OLED display, a touch display, and a projection display, and can also be a projection device and a projection screen. The tuner 210 receives broadcast television signals by wired or wireless reception, and demodulates audio and video signals from multiple wireless or wired broadcast television signals, such as and EPG data signals. The communicator 220 is a component for communicating with an external device or server according to various communication protocol types. For example: the communicator can include other network communication protocol chips or near field communication protocol chips such as Wifi modules, Bluetooth modules, wired Ethernet modules, and at least one of infrared receivers. The projection device 200 can establish the transmission and reception of control signals and data signals with the external control device 100 or the server 400 through the communicator 220. The detector 230 is used to collect signals of the external environment or the external interaction. The controller 250 and the tuner 210 can be located in different split devices, that is, the tuner 210 can also be in an external device of the main device where the controller 250 is located, such as an external set-top box. The user interface 280 can be used to receive control signals of a control device (such as an infrared remote controller, etc.).

[0054] In some embodiments, the controller 250 controls the operation of the display device and responds to the user's operation through various software control programs stored in the memory. The controller 250 controls the overall operation of the projection device 200. The user can input a user command in a graphical user interface (GUI) displayed on the display 260, and the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user can input a user command by inputting a specific sound or gesture, and the user input interface recognizes the sound or gesture through a sensor to receive the user input command.

[0055] In some embodiments, "user interface" is a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. The commonly used form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an interface element such as an icon, window, and control displayed on the display screen of an electronic device, where the control can include at least one of the visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc.

[0056] In order to explain this scheme in more detail, the following will be combined in an exemplary manner Figure 3 It is understood that although the steps in the flowchart of 3 are shown in sequence as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Figure 3 At least part of the steps in the above method may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps. The method for controlling a multi-projection device provided in the embodiment of the present disclosure shall prevail.

[0057] Figure 3 A flowchart of a multi-projection device control method provided by an embodiment of the present disclosure is provided. Applied to a multi-projection device control system, the multi-projection device control system includes multiple projection devices, and the multiple projection devices are connected to each other in communication, so that the multiple projection devices can communicate with each other. It should be noted that in the prior art, the multiple projection devices are also connected through HDMI transmission lines to achieve the transmission of audio and video signals between the multiple projection devices.

[0058] For example, Figure 4A A schematic diagram of a scenario for connecting multiple projection devices provided by an embodiment of the present disclosure, such as Figure 4A As shown, the multi-projection device control system includes three projection devices such as projection device 201, projection device 202 and projection device 203, which are connected via an HDMI transmission line, so that the projection device 201, projection device 202 and projection device 203 can transmit audio and video data signals via the HDMI transmission line, but is not limited to this. The present disclosure does not specifically limit it, and technical personnel in this field can set it according to actual conditions.

[0059] Optionally, one way to achieve communication connection between multiple projection devices may be to connect the suspended pin14 interface of the HDMI transmission line corresponding to each projection device to the general purpose input / output port (GPIO) of each projection device, so as to achieve communication connection between multiple projection devices.

[0060] Exemplarily, following the above embodiment, Figure 4B A schematic diagram of a scenario for connecting multiple projection devices provided by an embodiment of the present disclosure, such as Figure 4B As shown, for the projection device 201, the projection device 202 and the projection device 203, the suspended pin141 interface of the HDMI1 transmission line corresponding to the projection device 201 is connected to the GPIO1 port of the projection device 201 and the GPIO2 port of the projection device 202, respectively, and the suspended pin142 interface of the HDMI2 transmission line corresponding to the projection device 202 is connected to the GPIO2 port of the projection device 202 and the GPIO3 port of the projection device 203, respectively, so as to realize the communication connection between the projection device 201, the projection device 202 and the projection device 203, but not limited to this, the present disclosure is not specifically limited, and those skilled in the art can set it according to actual conditions.

[0061] Each projection device is provided with an arbitrator, which is used to determine the order in which each projection device responds to the control sent by the infrared control device among multiple projection devices. The arbitrator provided on each projection device can be implemented by providing a microcontroller unit (MCU) on each projection device, but is not limited thereto. The present disclosure does not specifically limit this, and those skilled in the art can configure it according to actual conditions.

[0062] like Figure 3 As shown, the multi-projection device control method specifically includes the following steps:

[0063] S31, generating a target random number corresponding to each projection device through the arbitrator of each projection device in response to the joint debugging control signal, and sending the target random number to other projection devices.

[0064] The joint control signal is used to instruct each projection device to receive the control signal of the same infrared control device. That is, it can be understood that the multiple projection devices included in the multi-projection device control system are controlled by the same infrared control device such as an infrared remote controller.

[0065] The target random number is used to determine the response order of each of the multiple projection devices in response to the infrared control signal. The target random number can be, for example, a hexadecimal number such as 5, but is not limited to this. The present disclosure does not specifically limit it, and those skilled in the art can set it according to actual conditions.

[0066] Specifically, when each projection device in the multi-projection device control system receives the joint control signal sent by the same infrared control device, it responds to the joint control signal, generates a target random number through the arbitrator set in each projection device, and sends the target random number to other projection devices in the multi-projection device control system.

[0067] Following the above embodiment, for the projection device 201, the projection device 202 and the projection device 203, when receiving the joint control signal sent by the same infrared control device, the arbitrators set in the projection device 201, the projection device 202 and the projection device 203 respectively generate corresponding target random numbers, such as, the target random number corresponding to the projection device 201 is 3, the target random number corresponding to the projection device 202 is 9, and the target random number corresponding to the projection device 203 is 7, but is not limited to this, the present disclosure does not specifically limit it, and those skilled in the art can set it according to actual conditions.

[0068] S32, determining, by the arbitrator of each projection device, a response order of the plurality of projection devices in response to the control signal sent by the infrared control device according to the plurality of target random numbers.

[0069] Specifically, when the arbitrator of each projection device in the multi-projection device control system receives the target random numbers corresponding to each projection device, it determines the response order of responding to the control signal when multiple projection devices simultaneously receive the control signal sent by the infrared control device based on the multiple target random numbers.

[0070] It should be noted that the target random number corresponding to each projection device carries the device identification of each projection device, and the device identification is a unique identification of each projection device. The device identification can be, for example, the device serial number of each projection device, but is not limited to this. The present disclosure does not specifically limit it, and those skilled in the art can set it according to actual conditions.

[0071] Optional, Figure 5 FIG. 1 is a flow chart of another multi-projection device control method provided by an embodiment of the present disclosure. Figure 5 As shown, one implementation of the above-mentioned execution S32 may be:

[0072] S51, sorting multiple target random numbers through an arbitrator corresponding to each projection device, and determining a response order of multiple projection devices in response to a control signal sent by an infrared control device according to the sorting result.

[0073] Specifically, when the arbitrator of each projection device in the multi-projection device control system receives the target random numbers corresponding to each projection device, it sorts the multiple target random numbers, and determines the response order of responding to the control signal when multiple projection devices simultaneously receive the control signal sent by the infrared control device according to the sorting result.

[0074] Exemplarily, following the above embodiment, the target random number corresponding to the projection device 201 is 3, the target random number corresponding to the projection device 202 is 9, and the target random number corresponding to the projection device 203 is 7, which are sorted in order from large to small. According to the sorting result, the projection device 201, the projection device 202 and the projection device 203 are determined. When they receive the control signal sent by the infrared control device at the same time, the response order of the control signal is: projection device 202>projection device 203>projection device 201, but not limited to this, the present disclosure does not specifically limit it, and technical personnel in this field can set it according to actual conditions.

[0075] In another example, the target random number corresponding to the projection device 201 is 3, the target random number corresponding to the projection device 202 is 9, and the target random number corresponding to the projection device 203 is 7. They can also be sorted in ascending order.

[0076] S33, receiving a control signal sent by the infrared control device, and responding to the control signal according to a response sequence.

[0077] Specifically, after receiving the control signal sent by the infrared control device, the projection device in the multi-projection device control system can respond to the control signal sent by the infrared control device according to the response sequence and perform the operation corresponding to the control signal.

[0078] The technical solution provided by the embodiment of the present disclosure is applied to a multi-projection device control system, which includes multiple projection devices. The multiple projection devices are communicatively connected with each other, and an arbitrator is arranged on each projection device. The arbitrator of each projection device can respond to a joint control signal, generate a target random number corresponding to each projection device, and send the target random number to other projection devices, wherein the joint control signal is used to instruct each projection device to receive control of a control signal from the same infrared control device; determine the response order of the multiple projection devices in response to the control signal sent by the infrared control device according to multiple target random numbers through the arbitrator of each projection device; receive the control signal sent by the infrared control device, and respond to the control signal according to the response order. In the above technical solution, after receiving the joint control signal, multiple projection devices can generate a target random number through the arbitrator set therein and send it to other projection devices, so that the projection devices can determine the response order of responding to the control signal sent by the infrared control device according to the target random numbers corresponding to the multiple projection devices respectively, so that the projection devices can respond to the control signal in sequence according to the response order, avoiding the problem in the prior art that multiple projection devices all respond when receiving the control signal at the same time, causing mutual influence between the multiple projection devices.

[0079] Optional, Figure 6 A flowchart of another multi-projection device control method provided in an embodiment of the present disclosure. Figure 6 is Figure 5 Based on the further optimization, the control signal includes a first control signal and a second control signal, the first control signal and the second control signal are used to control different projection devices, and the emission time of the first control signal and the second control signal are different. Based on this, Figure 6 As shown, one implementation of the above-mentioned execution S33 may be:

[0080] S61, after receiving the first control signal, the projection device determines a first projection device among a plurality of projection devices according to a response sequence.

[0081] The first projection device is the current plurality of projection devices, and is the first projection device among the plurality of projection devices to respond to the first control signal after receiving the first control signal sent by the infrared control device.

[0082] Specifically, after receiving the first control signal, the projection device in the multi-projection device control system can determine, according to the response order, the first projection device that first responds to the first control signal sent by the infrared control device among the multiple projection devices.

[0083] Exemplarily, following the above embodiment, for projection device 201, projection device 202 and projection device 203, the response order of responding to the control signal is determined according to the target random number: projection device 202>projection device 203>projection device 201, then it is determined that after receiving the first control signal, the first projection device that responds to the first control signal is projection device 202, but not limited to this, the present disclosure does not specifically limit it, and technical personnel in this field can set it according to actual conditions.

[0084] S62: The first projection device responds to the first control signal and sends a first instruction signal to the plurality of second projection devices.

[0085] Among them, the first indication signal is used to indicate multiple second projection devices. The first projection device has responded to the first control signal and performed the operation corresponding to the corresponding control signal. At this time, if other projection devices receive the second control signal sent by the infrared remote control device again, they can respond to the second control signal according to the response order.

[0086] It should be noted that, for the multiple projection devices, all of them can receive the first control signal sent by the infrared control device, but only the first projection device responds to the first control signal.

[0087] S63, after receiving the second control signal, the second projection device determines that the first projection device has responded to the first control signal, and determines a third projection device among the plurality of second projection devices according to a response sequence.

[0088] S64: The third projection device responds to the second control signal and sends a second instruction signal to multiple fourth projection devices.

[0089] The second indication signal is used to indicate to the plurality of fourth projection devices that the third projection device has responded to the second control signal.

[0090] Specifically, the first projection device in the multi-projection device control system sends a first indication signal to the multiple second projection devices in response to receiving the first control signal sent by the infrared remote control device, and indicates to the multiple second projection devices through the first indication signal that the current first projection device has responded to the first control signal. Correspondingly, for the multiple second projection devices, after receiving the second control signal sent by the infrared remote control device at this time, and determining that the first projection device has responded to the first control signal according to the first indication signal, the multiple second projection devices continue to determine the first third projection device that responds to the second control signal among the multiple second projection devices according to the response order, and the third projection device responds to the second control signal, and sends a second indication signal to the multiple fourth projection devices, and indicates to the multiple fourth projection devices through the second indication signal that the third projection device has responded to the second control signal.

[0091] It should be noted that, for multiple fourth projection devices, after receiving the third control signal subsequently sent by the infrared remote control device and determining that the third projection device has responded to the second control signal, they continue to respond to the third control signal according to the response sequence.

[0092] Optionally, based on the above embodiments, in some embodiments of the present disclosure, after controlling the first projection device and the second projection device among multiple projection devices, when it is necessary to control the first projection device again, the multiple projection devices need to exit the joint control state, receive the joint control signal again, and re-control the multiple projection devices by the same infrared control device.

[0093] Exemplarily, following the above embodiment, for the projection device 201, the projection device 202 and the projection device 203, the response order of the projection device 202 to the control signal is determined as follows: projection device 202>projection device 203>projection device 201. Then, among the projection devices 201, 202 and 203, it is determined that the first projection device is the projection device 202, and the plurality of second projection devices are the projection device 203 and the projection device 201. When the projection devices 201, 202 and 203 receive the first control signal at the same time, the projection device 202 responds to the first control signal first, executes the operation corresponding to the first control signal, and sends a first instruction signal to both the projection device 203 and the projection device 201, instructing the projection device 203 and the projection device 201 to respond to the first control signal first. 01, the current projection device 202 has responded to the first control signal. When the projection device 203 and the projection device 201 receive the second control signal, and according to the first indication signal, it is determined that the projection device 202 has responded to the first control signal, it can continue to determine, according to the response order, in the projection device 203 and the projection device 201, the third projection device that first responds to the second control signal is the projection device 203. After the projection device 203 responds to the third control signal, the projection device 201 sends a second indication signal to the projection device 201, indicating to the projection device 201 that the current projection device 203 has responded to the second control signal, so that the projection device 201 responds to the third control signal when receiving the third control signal, but is not limited to this. The present disclosure is not specifically limited, and those skilled in the art can set it according to actual conditions.

[0094] Thus, in the technical solution provided by the embodiment of the present disclosure, in the above process, when multiple projection devices simultaneously receive the control signal sent by the infrared remote control device, they can continue to respond to the control signal in sequence according to the response signal. In this way, it is avoided that when multiple projection devices are controlled by the same infrared remote control device, due to receiving the control signal at the same time, all respond, causing the problem of mutual influence between the multiple projection devices.

[0095] Optionally, based on the above embodiments, in some embodiments of the present disclosure, a timer is also provided on each projection device in a multi-projection device control system. The timer can be implemented by providing a micro control unit on each projection device, but is not limited to this. The present disclosure does not specifically limit this, and technicians in this field can set it according to actual conditions.

[0096] Based on this, the method further includes:

[0097] When each second projection device receives the first control signal, the timer of each second projection device starts timing, and when it is determined that the target waiting time is the preset waiting time, the first control signal is sent to the first projection device.

[0098] The target waiting time is the waiting time for the second projection device to receive the first indication signal sent by the first projection device. The preset waiting time refers to a parameter value used to determine whether the first projection device receives the control signal according to the target waiting time. The preset waiting time may be, for example, 60 seconds, but is not limited thereto. The present disclosure does not specifically limit this, and those skilled in the art may set it according to actual conditions.

[0099] Specifically, when each second projection device in the multi-projection device control system receives the first control signal sent by the infrared control device, it will start timing through the timer set on each second projection device, so as to obtain the target waiting time for each second projection device to receive the first indication signal sent by the first projection device, and compare the target waiting time with the pre-set preset waiting time. When the target waiting time is equal to the pre-set preset waiting time, it indicates that the first projection device may not have received the first control signal sent by the infrared remote control device. At this time, in order to enable the first projection device to respond to the first control signal and realize control of the first projection device, each second projection device sends the received first control signal to the first projection device.

[0100] Exemplarily, following the above embodiment, for the first projection device among the projection devices 201, 202 and 203, the projection device 202 is the first projection device, and the second projection device is the projection device 201 and the projection device 203. When the second projection device, i.e., the projection device 201 and the projection device 203, receives the first control signal sent by the infrared control device, the timer set by the projection device 201 and the projection device 203 will start timing, so as to obtain the target waiting time of the projection device 201 and the projection device 203 when receiving the first indication signal sent by the projection device 202, and compare the target waiting time with the preset waiting time of 60 seconds. When the target waiting time is equal to the preset waiting time of 60 seconds, it indicates that the projection device 202 may not have received the first control signal sent by the infrared remote control device. Then, the current projection device 201 and the projection device 203 send the first control signal they have received to the projection device 202, so that the projection device 202 can respond to the first control signal to control the projection device 202, but it is not limited to this. The present disclosure is not specifically limited, and those skilled in the art can set it according to actual conditions.

[0101] It should be noted that the above steps will also be performed in the specific implementation process of steps S63-S64 in the above embodiment, and will not be described in detail here.

[0102] In this way, in the technical solution provided by the embodiment of the present disclosure, in the above process, the target waiting time for receiving the first indication signal sent by the first projection device can be obtained through the timer set on each projection device, and the target waiting time can be compared with the preset waiting time. When the target waiting time is equal to the preset waiting time, it is determined that the first projection device may not have received the first control signal sent by the infrared remote control device. At this time, each second projection device sends the received first control signal to the first projection device, so as to ensure the control of the first projection device.

[0103] Optional, Figure 7 A flowchart of another multi-projection device control method provided in an embodiment of the present disclosure. Figure 7 is Figure 6 Further optimization based on Figure 7 As shown, before executing S31, the following steps are also included:

[0104] S71, when each projection device receives the joint debugging control signal, it sends an acquisition request to other projection devices.

[0105] Among them, the acquisition request is used to request the reception status of other projection devices receiving the joint debugging control signal, and the reception status is one of a received status and a non-received status. The received status indicates that the projection device has received the joint debugging control signal, and the non-received status indicates that the projection device has not received the joint debugging control signal.

[0106] S72, each projection device sends an acquisition request response to other projection devices in response to the acquisition request.

[0107] The acquisition request response carries a receiving status, and the receiving status is used to indicate whether the current device of other projection devices has received the joint debugging control signal.

[0108] Specifically, after receiving the joint control signal sent by the infrared remote control device, each projection device in the multi-projection device control system will send an acquisition request to other projection devices, and obtain the reception status of the joint control signal received by other projection devices through the acquisition request, and determine whether other projection devices have received the joint control signal through the reception status.

[0109] It should be noted that each projection device can receive the acquisition request response sent by other projection devices in the multi-projection device control system, so as to determine whether there is a projection device among the other projection devices included in the multi-projection device control system that has not received the joint control signal.

[0111] S81, when the receiving state carried by the acquisition request response is a non-receiving state, each projection device sends a joint debugging control signal to other projection devices.

[0112] Specifically, when the receiving status carried in the received acquisition request response is not the receiving status, the projection device in the multi-projection device control system determines that there is a projection device in other projection devices that has not received the joint control signal, and sends the received joint control signal to the other projection devices.

[0113] In the technical solution provided by the embodiment of the present disclosure, in the above process, when the multiple projection devices included in the multi-projection device control system receive the joint control signal, they can send an acquisition request to other projection devices, and through the acquisition request, obtain the reception status of the other projection devices receiving the joint control signal, and determine whether the other projection devices have received the joint control signal according to the reception status. In this way, it is ensured that the multiple projection devices can receive the joint control signal and respond to the joint control signal, so as to realize the subsequent control of the multiple projection devices included in the multi-projection device control system through the same infrared remote control device.

[0116] The exit control signal is used to instruct each projection device included in the multi-projection device control system to exit the control of the same infrared remote control device.

[0117] Specifically, each projection device in the multi-projection device control system receives the exit control signal sent by the infrared remote control device, and responds to the exit control signal according to the response sequence.

[0118] The specific implementation process of responding to the exit control signal according to the response sequence can refer to the implementation process of responding to the control signal sent by the infrared control device according to the response sequence in the above embodiment, which will not be repeated here.

[0119] In the technical solution provided by the embodiment of the present disclosure, in the above process, for the multi-projection device control system, when receiving the exit control signal sent by the infrared remote control device, multiple projection devices can respond to the exit control signal sent by the infrared control device according to the response order, thereby avoiding the problem of mutual influence between the multiple projection devices.
