[0032] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0033] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0034] Combination Figure 1 As shown in FIG. 1 , a conventional audio and video integration system includes a terminal device and an infrared remote controller. By operating the buttons on the infrared remote controller, the user can make the infrared remote controller send an infrared signal to the terminal device. After receiving the infrared signal, the terminal device executes the control instruction corresponding to the infrared signal. Thus, the user can control the application on the terminal device through the infrared remote controller.

[0035] However, in traditional audio and video integrated systems, when multiple infrared remote controllers control the same terminal device, the terminal device will receive multiple infrared signals from the multiple infrared remote controllers, and the terminal device cannot determine which infrared signal to process, resulting in abnormal infrared signal processing.

[0036] In view of this, the embodiments of the present disclosure provide a method and apparatus, device, and storage medium for processing infrared signals. The terminal device can use the signal lock to process the infrared signal generated by the infrared remote control, which can reduce the situation where the terminal device processes multiple infrared signals. When multiple infrared remote controls control the same terminal device, the abnormality of infrared signal processing can be reduced.

[0037] Combination Figure 2 As shown, an embodiment of the present disclosure provides an audio and video integration system, which includes an infrared remote controller, a camera, and a terminal device. The infrared remote controller can generate an infrared signal corresponding to a target button when a user operates the target button. The camera can receive the infrared signal corresponding to the target button sent by the infrared remote controller, and forward the infrared signal corresponding to the target button to the terminal device, so that the terminal device can process the infrared signal generated by the infrared remote controller using an integrated signal lock mechanism.

[0038] In the disclosed embodiments, the terminal device refers to an electronic device having a wired connection function and / or a wireless connection function. For example, the terminal device may be a mobile device, a computer, or a vehicle-mounted device built into a hover vehicle, or any combination thereof.

[0039] Optionally, the infrared signal generated by the infrared remote control can be sent directly to the terminal device using serial communication. Figure 2 After the infrared signal generated by the infrared remote controller T1 is sent to the terminal device, it can be received by the infrared serial port of the terminal device.

[0040] Optionally, a wireless communication connection or a wired communication connection can be established between the camera and the terminal device, and the camera can be remotely deployed relative to the terminal device. Figure 2 , when the camera is deployed remotely, the remotely located infrared remote controller T2 can send an infrared signal to the camera. After receiving the infrared signal, the camera can forward the infrared signal sent by the infrared remote controller T2 to the terminal device, thereby realizing the remote control of the terminal device by the infrared remote controller, wherein the infrared signal transmission process can follow TCP (Transmission Control Protocol). In addition, it should be noted that the camera is not limited to being deployed remotely. For example, when the terminal device of the audio and video integration system is deployed in a certain computer room, the camera can be deployed outside the computer room so that the camera can receive the infrared signal sent by the infrared remote controller outside the computer room, so that the user outside the computer room can control the terminal device in the computer room through the infrared remote controller. Of course, the camera can also be integrated into the terminal device as an infrared signal receiving module, which is not limited in the embodiments of the present disclosure.

[0041] based on Figure 2 In the audio and video integrated system shown in the figure, the embodiment of the present disclosure provides a method for processing infrared signals, which can be applied to terminal devices. Figure 3 As shown, the method includes:

[0042] S31, receiving a first infrared signal corresponding to a target button generated by an infrared remote controller, wherein the first infrared signal is generated when the target button of the infrared remote controller is pressed.

[0043] S32, determining the usage status of the signal lock.

[0044] S33: When the signal lock is in an idle state, process the first infrared signal.

[0045] S34, when the signal lock is in the occupied state, determine whether the signal identifier of the first infrared signal is the same as the signal identifier of the infrared signal of the currently occupied signal lock. The signal identifier is used to indicate the signal source of the infrared signal.

[0046] S35: If they are the same, process the first infrared signal.

[0047] S36: If they are not the same, discard the first infrared signal.

[0048] In the disclosed embodiment, the terminal device can use the signal lock to process the infrared signal generated by the infrared remote control. The signal lock only allows the terminal device to process a single infrared signal, and when the signal lock is in an occupied state, the terminal device can only process the infrared signal of the currently occupied signal lock. In this way, when the terminal device receives the first infrared signal corresponding to the target button generated by the infrared remote control, and the signal lock is idle, the first infrared signal can directly occupy the signal lock, and the terminal device processes the first infrared signal. In the case where the signal lock is occupied, it can be determined whether the signal source of the first infrared signal is the same as the signal source of the infrared signal currently occupying the signal lock. If they are the same, it is considered that the first infrared signal and the infrared signal of the currently occupied signal lock are the same signal, and the first infrared signal can be directly processed by the terminal device. If they are different, it is considered that the first infrared signal and the infrared signal of the currently occupied signal lock are not the same signal, and the first infrared signal can be discarded so that the terminal device only processes a single infrared signal. Thereby, the situation where the terminal device processes multiple infrared signals is reduced, and then when multiple infrared remote controllers control the same terminal device, the situation of abnormal infrared signal processing can be reduced.

[0049] Optionally, the signal identifier of the infrared signal is determined according to the signal source and transmission mode of the infrared signal. And the signal identifier of the infrared signal is determined according to the signal source and transmission mode of the infrared signal, including: when the infrared signal is forwarded to the terminal device via the camera, the IP address information of the infrared remote control is determined as the signal identifier of the infrared signal. Or, when the infrared signal is directly sent from the infrared remote control to the terminal device, the ID information of the serial port used to receive the infrared signal is determined as the signal identifier of the infrared signal.

[0050] Combination Figure 2As shown, in the embodiment of the present disclosure, when the infrared remote controller T1 directly sends an infrared signal to the terminal device, the infrared signal is sent to the infrared serial port of the terminal device. When the infrared remote controller T2 sends an infrared signal to the terminal device, the infrared signal is received and forwarded by the camera. For the infrared signal sent by the infrared remote controller T1, the terminal device uses the ID information of the infrared serial port as a signal identifier. For the infrared signal sent by the infrared remote controller T2, the terminal device uses the IP address information of the infrared remote controller T2 as a signal identifier. In this way, when both the infrared remote controller T1 and the infrared remote controller T2 send infrared signals to the terminal device, the infrared signals sent by the infrared remote controller T1 and the infrared remote controller T2 can be distinguished by the signal identifier. In addition, it should be noted that when multiple infrared remote controllers directly send multiple infrared signals to the terminal device in a serial communication mode, since the ID information of the serial ports corresponding to different infrared remote controllers is different, the infrared signals sent by different infrared remote controllers can be identified by different serial port ID information to distinguish the multiple infrared signals sent by the multiple infrared remote controllers. In the case where multiple infrared remote controls indirectly control a terminal device through a camera, the multiple infrared remote controls will send multiple infrared signals to the terminal device through the camera. Since different infrared remote controls have different IP address information corresponding to them, the infrared signals sent by different infrared remote controls can be identified by using different IP address information to distinguish the multiple infrared signals sent by the multiple infrared remote controls.

[0051] Optionally, determining the usage status of the signal lock includes: obtaining a lock identifier of the signal lock. If the lock identifier is an empty identifier, determining that the signal lock is idle. If the lock identifier is not an empty identifier, determining that the signal lock is occupied. The lock identifier is a signal identifier of an infrared signal currently occupying the signal lock.

[0052] In the disclosed embodiment, when the terminal device is processing an infrared signal, the signal lock will be in an occupied use state, and the lock identifier of the signal lock will be updated to be set to the signal identifier of the infrared signal currently occupying the signal lock. The lock identifier of the signal lock is used to reflect the signal source of the infrared signal currently occupying the signal lock. In this way, the method of determining the use state of the signal lock based on whether the lock identifier of the signal lock is an empty identifier can not only determine whether the signal lock is occupied, but also, when the signal lock is occupied, further determine which signal source (i.e., which infrared remote control) the infrared signal currently being processed by the terminal device comes from. Subsequently, when multiple infrared signals sent by the same signal source are received, the lock identifier of the signal lock can be used to determine whether the multiple infrared signals belong to the same signal source, so that the multiple infrared signals sent by the same signal source can be processed normally.

[0053] Optionally, processing the first infrared signal includes: parsing a first control instruction corresponding to the first infrared signal according to a preset mapping relationship, and executing the first control instruction.

[0054] In the disclosed embodiment, the terminal device cannot directly process the first infrared signal, and needs to convert the infrared signal into a control instruction that the terminal device can recognize. In this way, when the terminal device processes the first infrared signal, it can determine the first control instruction corresponding to the first infrared signal according to the mapping relationship between the key value carried by the infrared signal and the control instruction, so that the terminal device executes the first control instruction. Thus, the terminal device can run the function corresponding to the target key in the infrared remote control to meet the user's need to control the terminal device through the infrared remote control.

[0055] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for processing infrared signals, which can be applied to a terminal device. The method includes:

[0056] S41, receiving a first infrared signal corresponding to a target button generated by an infrared remote controller, wherein the first infrared signal is generated when the target button of the infrared remote controller is pressed.

[0057] S42: When a second infrared signal corresponding to the target button and generated by the infrared remote controller is received within a preset time period, the second infrared signal is processed.

[0058] S43, when the second infrared signal generated by the infrared remote controller and corresponding to the target button is not received within a preset time period, stop processing the first infrared signal and set the lock flag of the signal lock to an empty flag.

[0059] The second infrared signal is generated when a target button of the infrared remote controller is pressed or released.

[0060] Normally, when the target button of the infrared remote controller is pressed short, the terminal device will receive an infrared signal indicating that the target button has been lifted in a short period of time. Alternatively, when the target button of the infrared remote controller is pressed long, the terminal device will receive an infrared signal indicating that the target button has been pressed again in a short period of time. However, during the transmission of the infrared signal from the infrared remote controller to the terminal device, if it is interfered by other signals or the infrared remote controller fails, the infrared signal is easily lost. Since the subsequent infrared signal corresponding to the target button is lost, the terminal device cannot receive the subsequent infrared signal, which may cause the terminal device to continue to execute the infrared signal received previously, resulting in infrared signal processing errors.

[0061] For example, when the target button of the infrared remote control is pressed by the user, a down signal is generated and sent to the terminal device. When the target button of the infrared remote control is lifted, an up signal is generated and sent to the terminal device. When the target button of the infrared remote control is long pressed by the user, the terminal device will receive multiple down signals in a short period of time. However, after the terminal device receives the down signal, if the subsequent up signal is lost during the transmission process, the terminal device may continue to execute the previously received down signal, causing infrared signal processing errors.

[0062] In view of this, in the embodiment of the present disclosure, after receiving the first infrared signal corresponding to the target key, the terminal device can determine whether the second infrared signal corresponding to the target key is received within a preset time length, that is, determine whether the subsequent infrared signal corresponding to the target key is lost. If the second infrared signal is not received within the preset time length, it is determined that the subsequent infrared signal corresponding to the target key may be lost. At this time, the terminal device is controlled to stop processing the first infrared signal, which can reduce the situation of infrared signal processing errors. In addition, when it is determined that the subsequent infrared signal corresponding to the target key may be lost, the lock flag of the signal lock is promptly set to an empty flag, and the signal lock is set to an idle state. Thereby, the situation where the first infrared signal occupies the signal lock for a long time is reduced.

[0063] Optionally, the preset time length is set to t, 300ms≤t≤900ms. More specifically, t=400ms, 500ms, 600ms, 700ms or 800ms.

[0064] Optionally, when the second infrared signal is generated under the condition that the target button of the infrared remote control is pressed, the second control instruction corresponding to the second infrared signal is parsed according to the preset mapping relationship, and the second control instruction is executed. Alternatively, when the second infrared signal is generated under the condition that the target button of the infrared remote control is lifted, the third control instruction corresponding to the second infrared signal is parsed, the third control instruction is executed, and the lock flag of the signal lock is set to an empty flag, so that the signal lock is set to an idle state. In the embodiment of the present disclosure, if the terminal device receives the second infrared signal generated when the target button is lifted within a preset time length, it indicates that the user's control demand for controlling the terminal device through the target button of the infrared remote control has been processed. At this time, timely setting the lock flag of the signal lock to an empty flag and setting the signal lock to an idle state can reduce the situation where the first infrared signal occupies the signal lock for a long time.

[0065] Combination Figure 5 As shown, the embodiment of the present disclosure provides a processing device 500 for infrared signals, which can be integrated into a terminal device. The processing device 500 includes a signal receiving module 501 and a signal processing module 502.

[0066] The signal receiving module 501 is used to receive a first infrared signal corresponding to a target button generated by the infrared remote controller; wherein the first infrared signal is generated when the target button of the infrared remote controller is pressed;

[0067] The signal processing module 502 is used to process the first infrared signal when it is determined that the usage status of the signal lock is an idle state; when it is determined that the usage status of the signal lock is an occupied state, determine whether the signal identifier of the first infrared signal is the same as the signal identifier of the infrared signal of the currently occupied signal lock; wherein the signal identifier is used to characterize the signal source of the infrared signal; if they are the same, process the first infrared signal; if they are not the same, discard the first infrared signal.
