Illustratively, the display device is a television, and the smart device is a mobile phone. The television is not provided with a camera, a target application program (such as video call) needing to use the camera is started, the television sends a message requesting to share the camera of the mobile phone to the mobile phone, the mobile phone receives the request message, the mobile phone agrees to share the camera and sends a response message to the television, the mobile phone starts to shoot images, the television receives the response message of the mobile phone, starts to receive the target image sent by the mobile phone and displays the received target image on a display interface of the television in real time, and the mobile phone is used as the camera of the television.

It is understood that the image may be a still image or a video image.

It can be understood that both the intelligent device and the display device include a codec, the intelligent device transmits a target image obtained by encoding a captured image to the display device through the encoder, and the display device decodes the received target image through the decoder and then displays the decoded target image in real time.

In the embodiment of the application, when a user needs to use a camera of a display device (for example, the user uses the display device to take a picture or a video or make a call), but the display device is not provided with the camera, the display device communicates with the intelligent device to request the intelligent device to share the camera, and after the intelligent device agrees to share the camera, the display device can use the camera of the intelligent device to take a picture and display the taken picture on the display device. Therefore, the display equipment has the function of a related camera through sharing the camera of the intelligent equipment. In this scheme, need not to dispose the camera specially for display device, display device satisfies the demand that the user used the camera on display device through the camera of sharing smart machine, when having richened the display device function, does not increase hardware equipment again, has practiced thrift the cost.

In the embodiment of the present application, the transmission between the intelligent device and the display device may be through bluetooth connection, wiFi connection, or other network connections, and specifically, the embodiment of the present application is not limited.

In some embodiments, the smart device transmits the target image with the display device via a WiFi connection. Specifically, under the condition that the display device does not establish WiFi connection with the intelligent device, the display device requests to establish connection with the intelligent device, the intelligent device agrees to establish WiFi connection with the display device, the WiFi connection is successfully established, and the target image is transmitted through the established WiFi connection; in the event that the display device has established a WiFi connection with the smart device, the target image is transmitted over the WiFi connection. Compared with Bluetooth transmission, the transmission rate of the WiFi network is higher, and the transmission rate can be improved through the WiFi network.

It is understood that the request message and the response message transmitted between the display device and the smart device are messages in a target form, wherein the target form includes any one of the following: broadcast packets, generic attribute configuration GATT connections, wiFi networks. The embodiment of the application provides various forms for sending the request message and the response message, so that the appropriate forms for sending the request message and the response message can be determined according to actual use requirements, and the flexibility for sending the request message and the response message is improved.

It is understood that the Generic Attribute protocol (GATT) is a general specification for transmitting and receiving very short data segments, referred to as attributes (attributes), over bluetooth connections.

In some embodiments, the display device periodically sends out the request message in the form of a broadcast packet, the smart device receives the broadcast packet sent by the display device, agrees to share the camera with the display device, and then the smart device also sends a response message to the request message in the form of a broadcast packet. The information is transmitted in the form of the broadcast packet, the information (request information and response information) can be transmitted between the display device and the intelligent device under the condition of establishing connection, the information can also be transmitted under the condition of not establishing connection, the flexibility of information transmission is improved, meanwhile, if the connection is not established between the display device and the intelligent device, the information can be transmitted under the condition of not establishing connection, compared with the method of firstly establishing connection and then transmitting information, the camera of the intelligent device is used after the display device and the intelligent device negotiate before establishing connection, the communication process is simpler, and the negotiation efficiency of two communication parties is higher.

Illustratively, as shown in fig. 4, the format of the bluetooth broadcast packet may include: each packet is 31 bytes, and the bluetooth broadcast packet is divided into two parts, namely valid data (significant) and invalid data (non-significant). Valid data portion: contains several broadcast data units, called AD Structure. The composition of the AD Structure is: the first byte is the length value Len, indicating that the next Len bytes are the data portion. The first byte of the data part represents the type ADType of data and the remaining Len-1 bytes are the real data AD data. The AD type is very critical, and determines what the Data of AD Data represents and how to parse. Invalid data portion: since the length of the broadcast packet must be 31 bytes, if the valid data part is less than 31 bytes, the remainder is complemented with 0. This portion of data is invalid and, when interpreted, ignored. The information contained in the bluetooth broadcast packet may include: the name of the device, the coding and decoding protocols supported by the device, the optimal parameters of coding and decoding, the optimal code stream rate for transmitting video, the MAC address of the device, the WiFi MAC address of the device, the display format supported by the image and the like.

The broadcast packet may be a directional broadcast packet, that is, only a specific device within a certain range is allowed to receive the broadcast packet; the broadcast packet may also be an undirected broadcast packet, i.e., allowing all devices within a certain range to receive the broadcast packet; specifically, the embodiments of the present application are not limited according to actual situations.

In the embodiment of the present application, the request message and the response message may be broadcast packets in the same network, or broadcast packets in different networks.

In some embodiments, the request message is a broadcast packet message based on the first network, that is, the display device sends a broadcast packet containing the request message to the outside through the first network, and then the corresponding smart device also receives the broadcast packet through the first network; the response message is a broadcast packet message based on the second network, that is, the display device receives the broadcast packet containing the response message through the second network, and the corresponding intelligent device sends the broadcast packet through the second network; wherein the first network and the second network are different.

Illustratively, the display device sends a broadcast packet containing a request for sharing the camera information to the intelligent device through a Bluetooth network, and the display device receives the broadcast packet containing the consent to share the camera information returned by the intelligent device through a WiFi network; or the display equipment sends a broadcast packet containing a request for sharing the camera information to the intelligent equipment through the WiFi network, and the display equipment receives the broadcast packet containing the sharing camera information returned by the intelligent equipment through the Bluetooth network.

It can be understood that the display device periodically transmits the first broadcast packet through the first network, and there is no longer any guarantee that the display device will listen to the broadcast packets transmitted by the surrounding devices through the first network without missing. Therefore, in the embodiment of the application, the display device sends the request message through the first network, monitors the message through the second network, receives the monitored response message aiming at the request message, and sends and receives the response message through the two different networks, so that the message sending and monitoring are ensured not to conflict, the message missing is prevented, the message interaction time of both communication parties is saved, and the communication efficiency is improved.

In some embodiments, the display device and the smart device may perform bidirectional communication through the established GATT connection, the display device sends a request message for sharing the camera to the smart device, the smart device receives the request message and sends a response message to the display device, the display device receives the response message, and both message sending and receiving of the two parties of communication are connected through the established GATT. The display device and the intelligent device are connected through the GATT to transmit the messages, the target image is transmitted through the WiFi connection, different messages are transmitted through different network connections, and the bandwidth utilization rate is improved.

The GATT connection is established between the display device and the intelligent device, and can be established by discovering the intelligent device through received broadcast messages before the display device receives an operation instruction of using a camera by a user, actively sending a GATT connection establishment request to the intelligent device and further establishing the GATT connection; or after receiving an operation instruction of using the camera, the display device finds the intelligent device through the received broadcast message, and actively sends a GATT connection establishment request to the intelligent device so as to establish the GATT connection; specifically, the time for establishing the GATT connection between the display device and the intelligent device may be determined according to actual conditions, and the embodiment of the present application is not limited.

In some embodiments, the display device communicates with the smart device through the established WiFi connection, the display device sends a request message for sharing the camera to the smart device, the smart device receives the request message and sends a response message to the display device, the display device receives the response message, and both the sending and receiving of messages of the two parties of communication are connected through the established WiFi. In the case where a WiFi connection has been established between the display device and the smart device, since the transmission rate of WiFi is higher, in order to increase the transmission rate of the message, the message may be transmitted through the WiFi connection.

The display device and the intelligent device are connected through the established WiFi, the display device and the intelligent device can be connected to a WiFi network of the same local area network, and communication is achieved through connection of the same router; the display device and the intelligent device can be in different local area networks (without a router, hardware cost can be saved), and communication after WiFi direct connection is realized through socket connection; specifically, the WiFi connection mode is determined according to actual needs, and the embodiment of the present application is not limited.

The display device and the intelligent device are actively connected with the same WiFi network before receiving an operation instruction of a user for using a camera; or after the display device receives an operation instruction of using the camera by the user, the display device and the intelligent device are actively connected with the same WiFi network; specifically, the timing for establishing the WiFi connection between the display device and the intelligent device may be determined according to actual conditions, and the embodiment of the application is not limited.
