When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart of a data transmission method provided in an embodiment of the present disclosure, which is applied to a terminal device, and as shown in fig. 1, the data transmission method includes the following steps:
and step 101, receiving operation information sent by the remote control equipment.
The operation information comprises operation actions and equipment identification information; the operation action comprises an action executed for realizing a target function; the target function comprises a playing function of the target content or a display function of the target content.
Illustratively, when receiving operation information sent by a remote control device, a terminal device analyzes the operation information to obtain device identification information and operation actions carried in the operation information, where the operation actions are actions executed to implement a target function, the target function is a play function of target content or a display function of the target content, the play function of the target content includes a page-up function, a page-down function, an automatic play stop function, and the like of the target content, and the display function of the target content includes a screen-projecting function, a screen-projecting ending function, and the like; the operation actions are divided into two types, the first type of operation action is generated by pressing any one of an upper page turning key, a lower page turning key, an automatic playing key and a stop automatic playing key by a user, and the equipment identification information carried in the corresponding operation information can be 0; the second type of operation action is generated when the user presses the screen-projecting key or finishes the screen-projecting key, and the device identification information carried in the corresponding operation information may be 1.
And step 102, determining the target equipment according to the equipment identification information.
The target device comprises a transmitter of an audio-visual signal source device or a wireless audio-visual transceiving device, and the audio-visual signal source device can be a notebook computer, a desktop computer, a camera, a tablet computer and the like.
In an example, when the terminal device obtains the device identification information, a target device matched with the device identification information is searched in a pre-stored device list, wherein a corresponding relationship between the device identification information and a device name is stored in the device list, and when the device name corresponding to the device identification information is searched, the target device corresponding to the device identification information is determined, that is, it is determined that an operation action in the obtained operation information is control over display content on the audio-visual signal source device for the audio-visual signal source device; or to the transmitter of the wireless audio-visual transceiving equipment, the display content on the audio-visual signal source equipment is put on the display equipment; for example, the device list stores a corresponding relationship between identification information 0 and audio-visual signal source devices, and also stores a corresponding relationship between identification information 1 and transmitters of wireless audio-visual transceiving devices, and if the obtained device identification information is 0, the determined target device is the audio-visual signal source device; and if the acquired equipment identification information is 1, determining that the target equipment is a transmitter of the wireless video transceiving equipment.
And 103, generating a target event corresponding to the target equipment according to the operation action.
Illustratively, when the terminal device determines the target device, a corresponding target event is generated according to the performance and the operation action of the target device, so that the target device can identify the target event; for example, if the target device is an audio-visual signal source device, the generated target event corresponding to the target device is an event that can be identified by the audio-visual signal source device; and if the target equipment is the transmitter of the wireless video and audio receiving and transmitting equipment, the generated target event corresponding to the target equipment is an event which can be identified by the transmitter of the wireless video and audio receiving and transmitting equipment.
And 104, sending the target event to the target equipment, so that the target equipment executes the target event.
In an example, when a target event corresponding to a target device is generated, a terminal device sends the target event to the corresponding target device, so that the target device analyzes the target event and executes an operation action in the target event. For example, if the target device is an audio-visual signal source device and the operation action is a page-up action, when the audio-visual signal source device receives a target event corresponding to the page-up action, the audio-visual signal source device directly performs the page-up operation on the currently displayed target content, and the execution effect of the operation is equal to the execution effect of a user directly operating the "page-up" action on a keyboard or a mouse of the audio-visual signal source device.
Optionally, when the target device includes the transmitter of the wireless audio-visual transceiver device, the step of the target device executing the target event specifically includes the following steps:
and the transmitter transmits the target event to display equipment through the receiver of the wireless audio-video transceiver so that the display equipment executes the target event.
The display device can be a projector, a television, a display and the like.
For example, if the target device is a transmitter of the wireless audio-visual transceiver device, and the operation function is screen projection, when the transmitter receives a target event corresponding to screen projection, the transmitter directly transmits the target event corresponding to screen projection to a receiver of the wireless audio-visual transceiver device, the execution effect of the target event is equal to the execution effect of a user directly operating a screen projection action on a keyboard of the transmitter, and the receiver of the wireless audio-visual transceiver device transmits the target event corresponding to screen projection to the display device (for example, a projector), so that the display device displays the target content, and screen projection is achieved.
It should be noted that, in the wireless video transceiver in the prior art, an entity key is usually provided, and the entity key can implement the functions of "screen projection" and "screen projection termination".
It should be noted that, under the condition that a plurality of transmitters are connected to one receiver, the receiver may randomly connect one transmitter for data transmission, and the other transmitters are in a waiting state, at this time, as long as a user presses a "screen projection" key on the transmitter to be switched, the display device may be switched to the screen interface of the audio-visual signal source device connected to the transmitter.
Further, as shown in fig. 2, before executing step 101, the following steps 105 and 106 are also included:
and 105, receiving a request message sent by the remote control equipment.
The request message is used for requesting the identification information of the terminal equipment.
And 106, sending the identification information of the terminal equipment to the remote control equipment, so that the remote control equipment pairs the pairing code with the identification information of the terminal equipment to form a pairing database.
Illustratively, when receiving a request message sent by a remote control device, a terminal device analyzes the request message, and determines information required by the remote control device, that is, identification information of the terminal device, so that the identification information of the terminal device is sent to the remote control device, so that when receiving the identification information of the terminal device and obtaining a pairing code input by a user, the remote control device correspondingly stores the identification information of the terminal device and the pairing code input by the user to complete pairing, and if a plurality of terminal devices are connected with the remote control device, the plurality of terminal devices all send identification information of themselves to the remote control device, so that the remote control device correspondingly stores the identification information of each terminal device and the corresponding pairing code to form a pairing database.
It should be noted that, a pairing indicator lamp is further provided on the terminal device, and after the terminal device sends the identification information of the terminal to the remote control device, the terminal device controls the pairing indicator lamp to be turned on, so as to inform the user that the terminal device has received the request message and sent the identification information of the terminal to the remote control device, so that the user inputs the pairing code on the control panel of the remote control device after seeing that the pairing indicator lamp is turned on.
It should be noted that, the pairing indicator lamp may be disposed on an outer surface of the terminal device, and the lighting of the pairing indicator lamp may be flashing or continuously lighting for a predetermined time, which is not limited in this disclosure.
According to the data transmission method provided by the embodiment of the disclosure, when receiving operation information sent by a remote control device, a terminal device determines a target device according to device identification information in the operation information, and sends a target event generated according to an operation action in the operation information to the target device, so that the target device executes the operation action in the target event, wherein a target function corresponding to the operation action comprises a playing function of target content or a display function of the target content. Therefore, the terminal device disclosed by the invention can generate a target event corresponding to the playing function of the target content and a target event corresponding to the displaying function of the target content, and sends the generated target event to the corresponding target device, so that the integration of the functions of the PPT remote controller and the wireless audio-video transceiver in the prior art is realized, the PPT remote controller and the wireless audio-video transceiver share one HDMI interface, the USB interface resource of the audio-video signal source device is saved, and the use by a user is facilitated.
Fig. 3 is a flowchart of a data transmission method provided in an embodiment of the present disclosure, which is applied to a remote control device, and as shown in fig. 3, the data transmission method includes the following steps:
and step 301, acquiring operation information.
The operation information comprises an operation action and equipment identification information, and the equipment identification information is used for distinguishing target equipment aimed at by the operation action.
For example, a control panel is configured on the remote control device, as shown in fig. 4, a plurality of keys are arranged on the control panel, including a pairing code key and a function key, where the pairing code key includes 1 to 12 number keys, and the function key includes an up-turning key, a down-turning key, an automatic playing stop key, a screen-projecting end key, a pairing key, and the like, each number key may be paired with one terminal device, and the control panel shown in fig. 4 may control a maximum of 12 terminal devices at the same time; the up-turning key, the down-turning key, the automatic playing key and the stop automatic playing key are used for controlling PPT playing displayed on the audio-visual signal source equipment; the screen projection key and the screen projection ending key are used for controlling the content displayed on the audio-visual signal source equipment to be displayed on the display equipment; the pairing key is used for realizing pairing use of the remote control device and the terminal device.
For example, the remote control device stores in advance a corresponding list of each function key, device identification information, and operation action, and when a user presses a desired function key, the remote control device may search for the corresponding operation action and the corresponding device identification information according to the obtained function key, thereby obtaining the operation information.
It should be noted that the pairing code may be a number, or a letter, a symbol, or the like, and when the pairing code is a number, the pairing code key included on the control panel of the remote control device is a number key; when the pairing code is a letter, the pairing code key included on the control panel of the remote control device is a letter key; when the pairing code is a symbol, the pairing code key included on the control panel of the remote control device is a symbol key, which is not limited by the present disclosure.
For example, when the remote control device is connected to only one terminal device, and the remote control device acquires the operation information, the operation information is sent to the terminal device, so that the terminal device determines the target device according to the device identification information carried in the operation information, and sends the target event generated according to the operation action carried in the operation information to the target device, so that the target device executes the target event.
According to the data transmission method provided by the embodiment of the disclosure, after the remote control device sends the operation information to the terminal device, the terminal device determines the target device according to the device identification information in the operation information, and sends the target event generated according to the operation action in the operation information to the target device, so that the target device executes the operation action in the target event, wherein the target function corresponding to the operation action comprises a playing function of the target content or a display function of the target content. Therefore, the terminal device disclosed by the invention can generate a target event corresponding to the playing function of the target content and a target event corresponding to the displaying function of the target content, and sends the generated target event to the corresponding target device, so that the integration of the functions of the PPT remote controller and the wireless audio-video transceiver in the prior art is realized, the PPT remote controller and the wireless audio-video transceiver share one HDMI interface, the USB interface resource of the audio-video signal source device is saved, and the use by a user is facilitated.
Fig. 5 is a flowchart of a data transmission method provided in an embodiment of the present disclosure, which is applied to a remote control device, and as shown in fig. 5, the data transmission method includes the following steps:
and step 501, acquiring a pairing instruction.
For example, when a user needs to pair the remote control device with the terminal device, the user may press a pairing code key on a control panel of the remote control device, so that the remote control device obtains the pairing instruction.
The request message is used for requesting the identification information of the terminal equipment.
For example, when the remote control device obtains the pairing instruction, it is determined that pairing needs to be achieved at this time, and then a request message carrying the identification information of the requesting terminal device is sent to the terminal device, so that the terminal device feeds back the identification information of the terminal device.
For example, when the user determines that the terminal device has sent the identification information of the terminal device to the remote control device through the pairing indicator lamp, the user presses the corresponding pairing code key, that is, the pairing code is obtained by the remote control device.
And 504, pairing the pairing code and the identification information of the terminal equipment to form a pairing database.
Illustratively, when the remote control device acquires the pairing code and the identification information of the terminal device, the pairing code and the identification information of the terminal device are correspondingly stored to complete pairing, so as to form a pairing database.
For example, when a user sees that a pairing indicator lamp on the terminal device is turned on, the user presses a number key "1", so that the remote control device receives a digital signal generated by pressing the number key "1", where the digital signal includes a serial number, for example, the digital signal includes the serial number "1", and then the remote control device pairs the serial number 1 in the digital signal with the received identification information of the terminal device; thus, when the user presses the number key "1" on the control panel of the remote control device, the terminal device paired with the "1" can be controlled.
And 505, acquiring a target pairing code.
For example, when the remote control device is connected to a plurality of terminal devices and a user needs to control a specific terminal device, the user presses a corresponding pairing code key (e.g., a numeric key), that is, the remote control device obtains a target pairing code.
For example, a user presses a target pairing code key on a control panel of the remote control device first, so that the remote control device receives pairing code information, where the pairing code information includes a serial number represented by the target pairing code key; pressing the function key again to enable the remote control equipment to receive the operation information; for example, a user desires to perform a screen-casting operation on the terminal device 1, and if the terminal device 1 is paired with the serial number 1, the user presses the number key "1" first, and then presses the function key "screen-casting", so that the terminal device 1 can receive operation information including a "screen-casting" action, and device identification information carried in the operation information is 1.
It should be noted that, when the remote control device acquires the target pairing code, timing may be performed, if the instruction corresponding to the function key is not acquired within the preset time, it is considered that the user mistakenly presses, and at this time, the target pairing code is discarded; and if the instruction corresponding to the function key is acquired within the preset time, continuing to execute the following steps.

In an example, when the remote control device determines the target terminal device, the remote control device sends the acquired operation information to the target terminal device, so that the target terminal device determines the target device according to the device identification information, and sends a target event generated according to the operation action to the target device, so that the target device executes the target event, and the remote control device completes control of the target device.
