Therefore, the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in other embodiments", etc. appearing in different places in this specification are not necessarily References are made to the same embodiment, but rather to "one or more but not all embodiments" unless specifically stated otherwise. The terms “including,” “includes,” “having,” and variations thereof all mean “including but not limited to,” unless otherwise specifically emphasized.

The plurality involved in the embodiments of this application refers to more than or equal to two. It should be noted that in the description of the embodiments of this application, words such as "first" and "second" are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating. Or suggestive order.

In the application scenario shown in Figure 1, the user can control the electronic device (a mobile phone is used as an example in the figure) to start recording by touching the Bluetooth headset. Specifically, in (a) of Figure 1, the user wears a Bluetooth headset, and a Bluetooth connection is established between the Bluetooth headset and the electronic device. The electronic device enters the recording mode, and the display screen displays the recording interface. The user touches the Bluetooth headset and clicks on the body of the Bluetooth headset as shown in (b) of Figure 1, and the electronic device starts recording.

Figure 2 shows the process for users to control electronic devices through Bluetooth headsets to start recording. See Figure 2, the video recording control method of electronic equipment, including steps:

S201, the Bluetooth headset and the electronic device establish a Bluetooth connection channel.

The user can control the electronic device to search for Bluetooth headsets by performing operations on the electronic device. After the electronic device discovers the Bluetooth headset, the user performs an operation on the electronic device to control the electronic device to establish a connection with the Bluetooth headset.

Of course, if a Bluetooth headset is recorded in the Bluetooth connection history of the electronic device, the electronic device can automatically initiate a connection with the Bluetooth headset after turning on the Bluetooth function.

It should be noted that Bluetooth headsets and electronic devices can use the Bluetooth protocol to establish a Bluetooth connection channel. The specific implementation method of establishing a Bluetooth connection channel between a Bluetooth headset and an electronic device will not be explained here.

Normally, the Bluetooth connection channel established by Bluetooth headsets and electronic devices is an asynchronous connection less (ACL) link. The ACL link is the basic connection link of Bluetooth. It is generally used to transmit connection-type negotiation signaling and to maintain the Bluetooth connection. ACL links also support one-way transmission of data. For example, when an electronic device sends data to a Bluetooth headset through an ACL link, the Bluetooth headset cannot send data to the electronic device at the same time.

S202. The Bluetooth headset responds to the user's touch operation and analyzes the user's touch operation.

The Bluetooth headset is equipped with a sensor and a Bluetooth module, and the sensor is used to detect the user's touch operation. The user inputs touch operations on the Bluetooth headset. The Bluetooth headset's sensor detects touch operations. The sensor of the Bluetooth headset converts the detected touch operation into a touch command and transmits it to the Bluetooth module. The Bluetooth module parses the touch command to clarify the touch operation input by the user.

S203. The Bluetooth headset parses the user's touch operation as the first operation and generates the first instruction.

The Bluetooth module of the Bluetooth headset parses the touch commands corresponding to the user's touch operations. If the Bluetooth module determines that the user has input the first operation by analyzing the touch command, the Bluetooth module generates a first command, which is used to control the electronic device to start recording. In some embodiments, the first instruction may refer to the avrcp play instruction.

The first operation is a touch operation performed by the user on the Bluetooth headset, which can be understood as an operation for the user to control the electronic device through the Bluetooth headset to start recording. In one example, the first operation may be a click operation on the body of the Bluetooth headset. Of course, it may be set to a click operation on a specific position of the body of the Bluetooth headset, or a click operation at any position. In another example, the first operation may also be a touch operation on a button on the Bluetooth headset.

S204. The Bluetooth headset sends the first command to the electronic device.

The Bluetooth module of the Bluetooth headset can send the first command to the electronic device through the Bluetooth connection channel established with the electronic device.

S205. The electronic device receives the first command and detects whether the electronic device is in the video recording mode.

The Bluetooth module of the electronic device receives the first instruction and sends a first request to the audio module of the electronic device. The first request is used to control the electronic device to start recording. The audio module receives the first request and detects whether the electronic device is in recording mode.

In some embodiments, the audio module can detect whether the electronic device is in recording mode in the following two ways:

Method 1. The application layer or application framework layer of the software architecture of the electronic device sets a service. The function of the service is to identify whether the electronic device is in recording mode.

Based on this, after receiving the first instruction, the electronic device controls the operation of the service and obtains the operation result of the service. The electronic device can determine whether the electronic device is in the recording mode based on the operation results of the service.

Method 2: The electronic device traverses the currently running processes and determines whether the currently running processes include a video recording process. In some embodiments, the electronic device may determine whether the currently running process includes a video recording process through the process identifier.

Based on this, after receiving the first instruction, the electronic device traverses the currently running processes according to method 2 and determines whether the currently running processes include a video recording process.

It should also be noted that if the electronic device starts the camera operation and processes the video recording mode, the electronic device can detect that the electronic device is in the video recording mode according to the aforementioned two methods. When the electronic device is detected to be in the video recording mode, the electronic device may execute step S206. If the electronic device detects that the electronic device is not in the recording mode, the electronic device can exit the process of executing this method.

S206. The electronic device and the Bluetooth headset establish a SCO link.

Among them, the synchronous connection oriented (SCO) link is a Bluetooth physical link between the electronic device and the Bluetooth headset. The SCO link is a connection technology supported by Bluetooth baseband and uses reserved time slots to transmit data. The SCO link also supports bidirectional data transmission. For example, when the electronic device sends data to the Bluetooth headset through the SCO link, the Bluetooth headset can also send data to the electronic device through the SCO link.

In some embodiments, the method for establishing an SCO link between an electronic device and a Bluetooth headset includes:

The electronic device sends a connection command (Command) to the Bluetooth headset.

The Bluetooth headset receives the Command sent by the electronic device and returns an event (Event) to the electronic device. With this, the establishment of the SCO link between the electronic device and the Bluetooth headset is completed.

The electronic device can be understood as the host, and the Bluetooth headset can be understood as the slave. The host and slave can communicate through the interface (Host Controller Interface, HCI) in the form of Command and Event. Normally, the command is passed from the master to the slave, and the event is fed back from the slave to the master.

In some embodiments, the Command sent by the electronic device to the Bluetooth headset may be: HCI_Setup_Synchronous_Connection. The Event returned by the Bluetooth headset to the electronic device can be: HCI_Setup_Synchronous_Connection.

S207. The electronic device starts recording.

The SCO link between the electronic device and the Bluetooth headset is established, and the electronic device can start recording.

It can be understood that when the electronic device starts recording, it means that the electronic device captures video through the camera, but does not collect audio information through the microphone of the electronic device.

It should also be noted that when the user inputs a touch operation on the Bluetooth headset, the Bluetooth headset interprets the touch operation as an operation to control the electronic device to start recording. The electronic device determines that it is in the recording mode, and then the electronic device and the Bluetooth headset establish a SCO link. The electronic device starts recording, which enables the user to control the electronic device to start recording through the touch Bluetooth headset without operating the electronic device.

S208, Bluetooth headset collects audio information through the microphone.

Bluetooth headsets are equipped with one or more microphones for collecting audio information.

S209. The Bluetooth headset sends audio information to the electronic device through the SCO link.

The Bluetooth module of the Bluetooth headset sends the audio information collected by the microphone to the electronic device. The Bluetooth module of the electronic device receives the audio information sent by the Bluetooth headset and transmits it to the audio module of the electronic device.

It should be noted that the Bluetooth headset collects audio information through the microphone and transmits it to the electronic device, which can ensure that the user is in an area far away from the electronic device. The user's audio information can also be collected through the microphone of the Bluetooth headset.

In the method for starting recording of an electronic device proposed in the foregoing content, the user can control the electronic device to start recording by touching the Bluetooth headset. However, if the electronic device needs to be controlled to pause the recording, the user also needs to operate the electronic device. The reason was found: the electronic device and the Bluetooth headset established an SCO link, and the electronic device and the Bluetooth headset triggered the call process. Based on this, the Bluetooth headset runs the call process. After the electronic device and the Bluetooth headset establish the SCO link, if the user triggers the Bluetooth headset again, the Bluetooth headset will recognize the trigger operation as a hang-up operation in the call process and send an instruction to hang up the call to the electronic device. The electronic device receives an instruction to hang up the call. Since the electronic device is not currently on a call, it cannot respond to the instruction.

In order to enable the user to control the electronic device to pause recording by touching the Bluetooth headset, embodiments of the present application provide a video recording control method for the electronic device.

S313. The electronic device detects whether the electronic device is in recording mode.

The Bluetooth module of the electronic device receives the second instruction and sends a second request to the audio module of the electronic device. The second request is used to control the electronic device to suspend the call. The audio module receives the second request and detects whether the electronic device is in recording mode.

In some embodiments, the electronic device can detect whether the electronic device is in the video recording mode in the following two ways:

Method 1: After receiving the second instruction, the electronic device calls service A to identify whether the electronic device is in the video recording mode and obtains the operation result of the service. The electronic device can determine whether the electronic device is in the recording mode based on the operation results of the service.

Method 2: After the electronic device receives the second instruction, the electronic device traverses the currently running processes and determines whether the currently running processes include a video recording process. In some embodiments, the electronic device may determine whether the currently running process includes a video recording process through the process identifier.

It should also be noted that if the electronic device detects that the electronic device is in the video recording mode, the electronic device executes step S314. If the electronic device detects that the electronic device is not in the recording mode, the electronic device can exit the process of executing this method.

S314. The electronic device generates a pause command according to the second command. The pause command is used to control the electronic device to pause recording.

Wherein, the audio module of the electronic device generates a pause instruction according to the second instruction. In some embodiments, the pause instruction may refer to avrcp pause. Since the second command is used to control the electronic device to stop talking, it needs to be converted into an command to control the electronic device to pause recording.

After the electronic device generates a pause command, the electronic device will respond to the pause command and pause the recording. The electronic device pauses recording. If the user wants to continue recording with the electronic device, the user can click on the body of the Bluetooth headset as shown in Figure 6. The Bluetooth headset executes steps S302 to step S304, and the electronic device executes steps S305 to step S309 to achieve this. The electronic device continues to record.

It should be noted that, after the electronic device pauses recording, the user clicks on the body of the Bluetooth headset as shown in Figure 6 to control the electronic device to continue recording. When the Bluetooth headset and the electronic device perform steps S302 to S309, Step S306 may not be executed. In some embodiments, the Bluetooth headset and the electronic device perform steps S301 to S309 to enable the user to control the electronic device to start recording by touching the Bluetooth headset. If the SCO link established by the electronic device and the Bluetooth headset is not disconnected, then When the Bluetooth headset and the electronic device perform the process from step S302 to step S309 again, step S306 can no longer be used to repeatedly establish the SCO link.

It can be seen from the aforementioned steps S310 to S314 that the user can perform a touch operation on the Bluetooth headset. The Bluetooth headset can sense the user's touch operation, generate a second instruction and send it to the electronic device, and the electronic device will process the second instruction. It is converted into a pause command to control the electronic device to pause recording, so that the user does not need to operate the electronic device when he wants to pause the recording of the electronic device, and can only operate the Bluetooth headset.

It should also be noted that in some embodiments, before the electronic device executes step S314, it may also determine whether the electronic device is in a call state. If the electronic device determines that the electronic device is not in a call state, it means that the electronic device has only turned on recording, and step S314 can be executed.

Of course, the step of determining whether the electronic device is in the call state and the aforementioned step S313 can be executed in parallel, or step S313 is performed first and then the judgment of whether the electronic device is in the call state is performed, or the step S313 is performed first and then the step S313 is performed, and Unlimited.

In this embodiment, it is determined that the electronic device is not in the call state and the electronic device is in the recording mode. This means that the user's touch operation on the Bluetooth headset is to control the electronic device to pause recording. Therefore, step S314 is executed to record the electronic device. of pause.

It should also be noted that if the electronic device determines that the electronic device is not in the recording mode but is in a call state, the electronic device can end the call according to the second instruction in step S312.
