The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of this application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. It should also be understood that in the embodiments of the present application, "one or more" means one, two, or more than two; "and/or" describes the association relationship of the associated objects, indicating that three relationships may exist; for example, a and/or B, may represent: a alone, both A and B, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather mean "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

The embodiments of the present application relate to a plurality of numbers greater than or equal to two. It should be noted that, in the description of the embodiments of the present application, the terms "first", "second", and the like are used for distinguishing the description, and are not to be construed as indicating or implying relative importance or order.

In the application scenario shown in fig. 1, a user may control an electronic device (a mobile phone is taken as an example in the figure) to start recording by touching a bluetooth headset. Specifically, in fig. 1 (a), the user wears a bluetooth headset, and the bluetooth headset and the electronic device establish a bluetooth connection. The electronic equipment enters a video mode, and a display screen displays a video interface. When the user touches the bluetooth headset, the electronic device starts recording video by clicking the body of the bluetooth headset as shown in (b) of fig. 1.

Fig. 2 shows a flow of a user controlling an electronic device to start recording through a bluetooth headset. Referring to fig. 2, the video recording control method of the electronic device includes the steps of:

s201, the Bluetooth headset and the electronic equipment establish a Bluetooth connection channel.

The user can control the electronic device to search the Bluetooth headset by performing an operation on the electronic device. After the electronic equipment discovers the Bluetooth headset, a user executes operation on the electronic equipment to control the electronic equipment to be connected with the Bluetooth headset.

Of course, if the bluetooth headset is recorded in the history of the bluetooth connection of the electronic device, the electronic device may automatically initiate connection with the bluetooth headset after the bluetooth function is started.

It should be noted that the bluetooth headset and the electronic device may use a bluetooth protocol to establish a bluetooth connection channel. The specific implementation manner of the bluetooth headset and the electronic device establishing the bluetooth connection channel is not described herein.

Typically, the bluetooth connection channel established between the bluetooth headset and the electronic device is an Asynchronous Connection Less (ACL) link. The ACL link is a basic connection link of bluetooth, and is generally used for transmitting negotiation signaling of a connection class for maintaining a bluetooth connection. ACL links also support unidirectional transmission of data. Illustratively, when the electronic device sends data to the bluetooth headset over the ACL link, the bluetooth headset cannot simultaneously send data to the electronic device.

S202, the Bluetooth headset responds to the touch operation of the user and analyzes the touch operation of the user.

The Bluetooth headset is provided with a sensor and a Bluetooth module, and the sensor is used for detecting touch operation of a user. And the user inputs touch operation on the Bluetooth headset. The sensor of the bluetooth headset can detect touch operation. The sensor of the Bluetooth headset converts the detected touch operation into a touch instruction and transmits the touch instruction to the Bluetooth module. The Bluetooth module analyzes the touch instruction to determine the touch operation input by the user.

S203, the Bluetooth headset analyzes the touch operation of the user as a first operation and generates a first instruction.

And the Bluetooth module of the Bluetooth headset analyzes the touch instruction corresponding to the touch operation of the user. If the Bluetooth module determines that the user inputs the first operation by analyzing the touch instruction, the Bluetooth module generates a first instruction, and the first instruction is used for controlling the electronic equipment to start recording. In some embodiments, the first instruction may refer to an avrcp play instruction.

The first operation is a touch operation of the user on the bluetooth headset, and can be understood as an operation provided for the user to control the electronic device to start recording through the bluetooth headset. In one example, the first operation may be a single-click operation on the body of the bluetooth headset, and may be, of course, a single-click operation on a specific location of the body of the bluetooth headset, or a single-click operation on an arbitrary location. In another example, the first operation may also be a touch operation on a key on the bluetooth headset.

S204, the Bluetooth headset sends a first instruction to the electronic equipment.

The Bluetooth module of the Bluetooth headset can send a first instruction to the electronic equipment through a Bluetooth connection channel established with the electronic equipment.

S205, the electronic equipment receives the first instruction and detects whether the electronic equipment is in a video recording mode.

The Bluetooth module of the electronic equipment receives the first instruction and sends a first request to the audio module of the electronic equipment, wherein the first request is used for controlling the electronic equipment to start recording. The audio module receives the first request and detects whether the electronic equipment is in a video recording mode.

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

mode 1, an application layer or an application framework layer of a software architecture of an electronic device sets a service, and the service has the functions of: whether the electronic equipment is in a video recording mode is identified.

Based on this, after the electronic device receives the first instruction, the electronic device controls the service to operate, and obtains an operation result of the service. The electronic device may determine whether the electronic device is in a video recording mode based on the operational result of the service.

And in the mode 2, the electronic equipment traverses the currently running process and judges whether the currently running process comprises a video recording process. In some embodiments, the electronic device may determine whether the currently running process comprises a video recording process by the process identifier.

Based on this, after the electronic device receives the first instruction, according to the mode 2, the currently running process is traversed, and whether the currently running process includes a video recording process is judged.

It should be noted that, if the electronic device starts the camera to operate and handles the video recording mode, the electronic device may detect that the electronic device is in the video recording mode according to the two manners described above. When the electronic device is detected to be in the video recording mode, the electronic device may execute step S206. If the electronic equipment detects that the electronic equipment is not in the video recording mode, the electronic equipment can quit the process of executing the method.

S206, the electronic equipment and the Bluetooth headset establish an SCO link.

Wherein, the Synchronous Connection Oriented (SCO) link belongs to a bluetooth physical link between the electronic device and the bluetooth headset. The SCO link is a connection technology supported by the bluetooth baseband and uses reserved time slots to transmit data. The SCO link also supports bi-directional data transfer. Illustratively, when the electronic device sends data to the bluetooth headset over the SCO link, the bluetooth headset may also send data to the electronic device over the SCO link.

In some embodiments, the manner in which the electronic device and the bluetooth headset establish the SCO link includes:

the electronic device sends a connection Command (Command) to the bluetooth headset.

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

The electronic device can be understood as a master and the bluetooth headset can be understood as a slave. The Host and the slave can communicate through an Interface (HCI) in the form of Command and Event. In general, command is transmitted from the master to the slave, and 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 _ synchronization _ Connection. The Event returned by the bluetooth headset to the electronic device may be: HCI _ Setup _ synchronization _ Connection.

And S207, starting video recording by the electronic equipment.

And the SCO link between the electronic equipment and the Bluetooth headset is established, and the electronic equipment can start recording.

It is understood that the electronic device starts recording refers to the electronic device shooting video through a camera, but audio information is not collected through a microphone of the electronic device.

It should be further noted that, a user inputs a touch operation to the bluetooth headset, the bluetooth headset analyzes the touch operation to control the electronic device to start recording, and the electronic device determines that the electronic device is in a recording mode, and then the electronic device and the bluetooth headset establish an SCO link, and the electronic device starts recording, so that the user can control the electronic device to start recording through the touch bluetooth headset without operating the electronic device.

And S208, the Bluetooth headset collects audio information through a microphone.

The bluetooth headset is provided with one or more microphones for gathering audio information.

S209, the Bluetooth headset sends audio information to the electronic equipment through the SCO link.

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

It should be noted that, the bluetooth headset collects the audio information through the microphone and transmits the audio information to the electronic device, which can ensure that the user is located in an area far away from the electronic device, and can also collect the audio information of the user through the microphone of the bluetooth headset.

In the method for starting video recording of the electronic device proposed in the foregoing description, the user may control the electronic device to start video recording through the touch bluetooth headset, but if the user needs to control the electronic device to suspend video recording, the user needs to operate the electronic device. The reason is found as follows: the electronic equipment and the Bluetooth headset establish an SCO link, and the electronic equipment and the Bluetooth headset trigger a call process. Based on this, the bluetooth headset runs a call flow. After the SCO link is established between the electronic equipment and the Bluetooth headset, the user triggers the Bluetooth headset again, the Bluetooth headset can determine that the triggering operation is a hang-up operation in a call flow, and a hang-up instruction is sent to the electronic equipment. The electronic equipment receives the instruction of hanging up the call, and the electronic equipment cannot respond to the instruction because the call is not carried out by the existing electronic equipment.

The user inputs a touch operation on the bluetooth headset, such as the touch operation of double-clicking the body of the bluetooth headset shown in fig. 8. The sensor of the Bluetooth headset senses the touch operation of a user, converts the touch operation into a corresponding touch instruction and transmits the touch instruction to the Bluetooth module of the Bluetooth headset. The Bluetooth module analyzes the touch instruction to determine the touch operation input by the user.

And S311, the Bluetooth headset analyzes the touch operation of the user as a second operation and generates a second instruction.

And the Bluetooth module of the Bluetooth headset analyzes the touch instruction corresponding to the touch operation of the user. If the Bluetooth module determines that the user inputs the second operation by analyzing the touch instruction, the Bluetooth module generates a second instruction, and the second instruction is used for controlling the electronic equipment to end the call. In some embodiments, the second instruction may refer to a hang (hang) instruction.

The second operation is also a touch operation of the user on the bluetooth headset, and can be understood as an operation provided for the user to control the electronic device to pause video recording through the bluetooth headset. In one example, the second operation may be a single-click operation or a double-click operation on the body of the bluetooth headset, and may be set to a single-click operation or a double-click operation on a specific position of the body of the bluetooth headset. When both the first operation and the second operation are click operations, the manipulation position of the second operation is different from the manipulation position of the first operation. In another example, the first operation may also be a touch operation on a key on the bluetooth headset, and the key is different from the key of the first operation.

It should be noted that, because the SCO link is established between the bluetooth headset and the electronic device, the bluetooth headset is in a call process, and therefore, when a user performs a touch operation on the bluetooth headset and needs to control the electronic device to pause video recording, the bluetooth headset may analyze the touch operation to control the electronic device to end a call, and generate a call ending instruction.

And S312, the Bluetooth headset sends a second instruction to the electronic equipment.

The bluetooth module of the bluetooth headset may send the second instruction to the electronic device through the bluetooth connection channel established in step S301 with the electronic device.

S313, the electronic equipment detects whether the electronic equipment is in a video recording mode.

And the Bluetooth module of the electronic equipment receives the second instruction and sends a second request to the audio module of the electronic equipment, wherein the second request is used for controlling the electronic equipment to suspend the conversation. And the audio module receives the second request and detects whether the electronic equipment is in a video recording mode.

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

in the mode 1, after the electronic equipment receives the second instruction, the service A is called to identify whether the electronic equipment is in the video recording mode, and the operation result of the service is obtained. The electronic device may determine whether the electronic device is in a video recording mode based on the operational result of the service.

In the mode 2, after the electronic device receives the second instruction, the electronic device traverses the currently running process and judges whether the currently running process comprises a video recording process. In some embodiments, the electronic device may determine whether the currently running process comprises a video recording process by the process identifier.

It should 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 equipment detects that the electronic equipment is not in the video recording mode, the electronic equipment can quit the process of executing the method.

And S314, the electronic equipment generates a pause instruction according to the second instruction, wherein the pause instruction is used for controlling the electronic equipment to pause video recording.

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

After the electronic equipment generates the pause instruction, the electronic equipment responds to the pause instruction and pauses the video recording. The electronic device suspends video recording, if the user wants to continue using the electronic device for video recording, the user can click the body of the bluetooth headset as shown in fig. 6, the bluetooth headset performs steps S302 to S304, and the electronic device performs steps S305 to S309 to realize that the electronic device continues video recording.

It should be noted that, in order to achieve the purpose that the user clicks the main body of the bluetooth headset to control the electronic device to continue recording after the electronic device suspends recording, step S306 may not be executed in the process from step S302 to step S309 performed by the bluetooth headset and the electronic device. In some embodiments, the bluetooth headset and the electronic device execute steps S301 to S309 to enable the user to control the electronic device to start recording by touching the bluetooth headset, and if the SCO link established between the electronic device and the bluetooth headset is not disconnected, the bluetooth headset and the electronic device execute steps S302 to S309 again, and the SCO link may not be repeatedly established in step S306.

As can be seen from the foregoing steps S310 to S314: the user accessible is at bluetooth headset execution touch-control operation, and bluetooth headset perception user's touch-control operation generates the second instruction and sends to electronic equipment, and electronic equipment converts the second instruction into the pause instruction in order to control electronic equipment pause video recording, has realized that the user need not to operate electronic equipment when wanting to pause electronic equipment video recording yet, can only operate bluetooth headset.

It should be noted that, in some embodiments, before the electronic device performs step S314, it may also be determined whether the electronic device is in a call state. If the electronic device determines that the electronic device is not in the call state, it indicates that the electronic device only starts the video recording, and step S314 may be executed.

Of course, the step of determining whether the electronic device is in the call state and the step S313 may be executed in parallel, or the step S313 is executed first and then the step S313 is executed.

In this embodiment, if it is determined that the electronic device is not in the call state and the electronic device is in the video recording mode, it indicates that the touch operation input by the user to the bluetooth headset is to control the electronic device to pause video recording, so step S314 is executed to pause video recording of the electronic device.

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

If the electronic device determines that the electronic device is in the video recording mode and the call state, the electronic device can execute the following three modes after receiving the second instruction:

in the method 1, the electronic device is controlled to pause the video recording by executing the step S314.

In the method 2, the call is terminated according to the second command in the step S312 without executing the step S314.
