The following disclosure provides many different embodiments or examples for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention.
The embodiment of the invention provides a data transmission method, which is applied to a user side 1 of a data transmission system. As shown in fig. 2, the data transmission system further includes a device 2 and a cloud 3, and the data of the user 1 is transmitted to the device 2 through the cloud 3. The user terminal 1 includes, but is not limited to, a mobile phone, a tablet computer, a computer or a smart wearable device. The device side 2 may be an intelligent appliance with a display screen, such as an intelligent television, an intelligent air conditioner, an intelligent refrigerator, and the like.
The data transmission method of this embodiment can be applied to the user terminal 1, as shown in fig. 1, and includes the following steps:
The first data may be video data, and is stored locally at the user end 1. The first data address is a URL (Uniform Resource Locator) address corresponding to the cloud 3 of the first data.
The second data may be picture data (for example, a first frame picture of a video, or a certain frame picture thereof, which may be used as a cover page of the video), and the second data address is a URL address corresponding to the second data in the cloud 3. The data size of a general picture is much smaller than that of a video.
In the above step, the URL address of the first data and the URL address of the second data are merged into a data transmission message, where the data transmission message includes a video URL address and a picture URL address.
In an embodiment, the foregoing steps include sending the data transmission message to the cloud end 3, so that the device end 2 receives, stores, and obtains the second data and the first data address according to the data transmission message.
The data transmission message is transmitted to the device end 2 through the cloud end 3, so that the device end 2 downloads the second data (namely, the video cover pictures) according to the URL address of the second data in the data transmission message after receiving the data transmission message and displays the second data on the display screen of the device end. The user decides whether to watch the video or not according to the cover picture. For example, if it is decided to watch a video, and a picture is clicked, the corresponding first data (i.e., the video) is downloaded according to the URL address of the first data in the data transmission message. If the user does not want to watch the data, the device 2 does not need to download the first data, thereby saving network resources and storage space of the user.
The first data address and the second data address with smaller data volume are sent to the equipment end 2, the equipment end 2 can download the second data with smaller data volume rapidly according to the second data address, and then the second data are displayed, so that the caching time of the first data is reduced. After the user can review the second data again, if the first data needs to be acquired, the device 2 can download the first data from the cloud 3 according to the first data address. If the first data does not need to be acquired, the device end 2 does not need to download the first data, so that the data storage space of the device end 2 is saved, and the user can quickly see the cover picture of the video.

And after the device end 2 successfully downloads the first data, a message that the first data is successfully downloaded and returned by the device end 2 can be received through the cloud end 3.
In one embodiment, after the step of sending the data transmission message to the cloud end 3, the method further includes:
and receiving a second confirmation message from the cloud 3, wherein the second confirmation message is generated and returned to the cloud 3 after the device end 2 fails to receive the data transmission message.
Through the steps, the second confirmation message returned by the cloud end 3 is received, the fact that the data transmission message is not successfully received by the equipment end 2 is shown, at the moment, the user end 1, the cloud end 3 and the equipment end 2 can carry out self-checking, and if no abnormal problem exists after the self-checking, the data transmission message is sent to the equipment end 2 again through the cloud end 3.
In one embodiment, before the step of transmitting the first data to the cloud 3, the method further includes:
the first data is divided into a plurality of sub data.
In the above steps, the first data is stored locally at the user end 1, and does not need to be downloaded from the internet, so that the first data (i.e. video) can be rapidly processed on the user end 1 and divided into multiple frames of pictures.
One of the plurality of sub data is selected as the second data.
In the above steps, a first frame of picture may be selected from the multiple frames of pictures of the video as the second data, or another certain frame of picture may be selected as the second data.
In one embodiment, before step 400, the method further comprises:
and acquiring the identification mark of the equipment end 2, wherein the identification mark is recorded in the cloud end 3 after the equipment end 2 establishes network connection with the cloud end 3.
In the above steps, after the device 2 establishes the network connection with the cloud 3, the identification mark of the device 2 is registered on the cloud 3.
And determining the equipment end 2 needing to receive data according to the identification mark.
In the above steps, when the user side 1 sends the video to the device side 2, the device side 2 that receives the first data is selected on the user side 1, and then the device side 2 is set as the target device side 2 according to the identification mark of the device side 2, so that the cloud side 3 sends the data to the corresponding target device side 2 according to the identification mark of the target device side 2 after receiving the data.
In one embodiment, before step 100, the method further comprises:
and sending authentication information to the cloud 3.
In the above step, the authentication information may include the identification identifier of the user end 1, the cloud end 3 stores a white list of the user end 1, and only when the identification identifier of the user end 1 is in the white list of the user end 1, the user end 1 has the right to send the first data to the device end 2, so that the illegal user end 1 can be prevented from sending unsafe data to the device end 2.
And receiving an identity information verification result returned by the cloud end 3.
In the above steps, if the result of the authentication of the identity information is legal, it indicates that the user side 1 can send data to the device side 2, and if the result of the authentication of the identity information is illegal, it indicates that the user side 1 cannot send data to the device side 2. Whether the identification mark of the user side 1 is newly added to the white list of the user side 1 can be determined according to actual conditions, and synchronous updating is carried out at the cloud side 3.
In this embodiment, the identification identifiers of the ue 1 and the device 2 may include, but are not limited to, a Media Access Control Address (MAC Address, a Media Access Control Address, or a local area network Address), a Universal Unique Identifier (UUID), and a Mobile Equipment Identifier (MEID).

(5) The cloud 3 stores the cover picture and returns the URL address of the cover picture to the user terminal 1.
(6) The user side 1 stores the URL address of the cover picture.
(7) The user side 1 splices the URL address of the video and the URL address of the cover picture to generate a data transmission message, which may be a video message, and then transmits the video message to the cloud side 3.
(8) The cloud 3 sends the video message to the device 2.
(9) The device terminal 2 stores the video message, downloads the cover picture according to the URL address of the cover picture, displays the cover picture to the user through the display screen, and returns confirmation information of the received video message to the cloud terminal 3.
(10) The cloud 3 returns the confirmation information to the user terminal 1.
