It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
First, it should be noted that the sending end and the receiving end are two devices connected to each other, and specifically, the sending end and the receiving end are connected through a wireless network. In the mainstream audio and video transmission scheme in the prior art, a streaming media mode is mostly adopted, a sending end transmits transmission data to a receiving end, but the receiving end cannot transmit the data back to the sending end, and only audio and video data can be transmitted between the video sending end and the receiving end. The method and the device are based on a new data organization form, and can realize various data such as audio, video, configuration data, control information and the like after data connection, and realize bidirectional transmission between the sending end and the receiving end.
According to an embodiment of the present application, a method for wirelessly transmitting data is provided, which is suitable for establishing a receiving end of a sink service, and as shown in fig. 1, the method includes the following steps S101 to S104:
s101: and receiving transmission data of a transmitting end.
The transmitting end is a transmitting end for establishing source service, when the transmitting end transmits transmission data, the receiving end can receive the transmission data in a wireless connection mode, and optionally, the transmission data is one or more of audio and video data, first configuration information data for configuring the audio and video data (such as configuring operations of adjusting high brightness and low volume of the audio and video) and control information data for controlling the audio and video (such as operations of pausing the audio and video and playing the next audio and video).
S102: and analyzing the transmission data, and demonstrating and/or processing the analyzed transmission data.
In order to ensure convenience of transmission, before sending data to be transmitted, a sending end performs compression coding on the data to be transmitted, for example, a compression coding format such as h.264, h.265 and the like can be used as a compression method for video data, so that compressed transmission data is obtained, compression of the data is realized, the size of the data is reduced, and faster transmission is realized. At this time, after receiving the transmission data, the receiving end may decode the transmission data according to the compression coding format of the transmission data, so as to obtain the data before compression (i.e., the data to be transmitted at the transmitting end). Meanwhile, the receiving end can perform corresponding audio and video demonstration and/or configuration and control information processing on the data before compression.
S103: and generating confirmation information corresponding to the transmission data based on the second configuration information and/or the operation information.
When a user operates at a receiving end (for example, configuration information modification such as volume adjustment and the like is performed on audio and video in transmission data, operations such as resolution modification, code stream setting, format modification and the like are performed on video in transmission data), the receiving end generates confirmation information according to the configuration information and/or operation information of the user, wherein the configuration information can be information generated by configuration such as volume adjustment and the like on the audio and video in the transmission data, and the operation information can be information generated by operations such as resolution modification, code stream setting, format modification and the like. Optionally, the acknowledgement information is ack information.
S104: and returning the confirmation information to the sending end so that the sending end adjusts the transmission data according to the confirmation information.
The acknowledgement information generated in step S103 is transmitted back to the sending end in a wireless transmission manner, and then the sending end may adjust the transmission data sent in step S101 according to the acknowledgement information.
Optionally, the acknowledgement information may be generated based on the second configuration information and/or the operation information, or may be information that is generated to confirm that the transmission data is received after the receiving end receives the transmission data sent by the sending end. In this case, the receiving end returns an acknowledgement message to the transmitting end, and the transmitting end acknowledges that the receiving end has received the transmission data. If the sending status of the sending end is successful sending the transmission data, but the sending end does not receive the confirmation information returned by the receiving end within the preset time threshold (such as 1S, 5S, 30S, and the like), that is, the receiving end does not receive the transmission data or the receiving end cannot send the confirmation information at present, at this time, the sending end resends the transmission data, and the receiving end repeatedly executes step S101.
Further, the receiving end includes a peripheral input device, which may be a device that is convenient for a user to operate, such as a touch screen, a mouse, a keyboard, and the like, the user may configure and/or operate the transmission data through the external device, and the receiving end may generate confirmation information corresponding to the transmission data based on the configuration and/or operation of the user, that is, the second configuration information and/or the operation information, so as to implement a function of remote operation.
According to an embodiment of the present application, a method for wirelessly transmitting data at a transmitting end of a source service is provided, as shown in fig. 1, the method includes steps S201 to S203 as follows:
s201: and carrying out compression coding on the data to be transmitted to generate transmission data.
In order to ensure convenience of transmission, before sending data to be transmitted, a sending end performs compression coding on the data to be transmitted (the data to be transmitted is one or more of audio and video data, configuration information data and control information data), for example, a compression method of the video data can be a compression coding format such as h.264 and h.265, so as to obtain compressed transmission data, realize compression of the data, reduce the size of the data, and realize faster transmission.
S202: and sending the transmission data to a receiving end.
And the transmitting end transmits the transmission data to the receiving end for establishing the sink service in a wireless connection mode. The receiving end may start to execute step S101, and the receiving end may further analyze and then demonstrate and/or process the transmission data, and generate confirmation information corresponding to the transmission data based on the second configuration information and/or the operation information, where the configuration information may be information generated by configuring, such as adjusting volume, audio and video in the transmission data, and the operation information may be information generated by performing operations, such as modifying resolution, setting code stream, modifying format, and the like.
S203: and when receiving confirmation information corresponding to the transmission data returned by the receiving terminal, adjusting the transmission data according to the confirmation information, and retransmitting the adjusted transmission data to the receiving terminal.
The sending end receives the confirmation information of step S103 sent by the receiving end in a wireless connection manner, adjusts the transmission data corresponding to the confirmation information according to the confirmation information, and resends the adjusted transmission data to the receiving end. Optionally, the acknowledgment information may also be information that confirms that the receiving end has received the transmission data, in this case, if the sending state of the sending end is that the transmission data is successfully sent, but the sending end does not receive the acknowledgment information returned by the receiving end within a preset time threshold (e.g., 1S, 5S), that is, the receiving end does not receive the transmission data or the receiving end cannot send the acknowledgment information at present, at this time, the sending end resends the transmission data, and the receiving end repeatedly executes step S101.
Several specific application scenarios are given for the wireless data transmission method according to the embodiment of the present application:
as an example, when the transmitting end is a mobile terminal and the receiving end is AR glasses. The mobile terminal can compress and encode the original video (namely the data to be transmitted in the embodiment of the application) through the encoding format of H.265 to obtain transmission data, and the mobile terminal sends the compressed transmission data to the AR glasses in a wireless connection mode. After receiving the transmission data sent by the mobile terminal, the AR glasses decode according to the encoding format of H.265 to obtain the original video. Specifically, when the user brightens the brightness of the original video (i.e., the second configuration information in the embodiment of the present application) through the touch screen, the AR glasses generate ack information (i.e., the confirmation information in the embodiment of the present application) according to the brightened brightness, and return the ack information to the mobile terminal. When receiving the ack information, the mobile terminal adjusts the original video accordingly according to the ack information, that is, brightens the brightness of the original video. In addition, when the AR glasses receive the transmission data sent by the mobile terminal, an ack message that the reception is confirmed is firstly returned to the mobile terminal, so that the mobile terminal can confirm the reception condition of the transmission data. If the mobile terminal does not receive ack information of the AR glasses, which is confirmed to be received, within 15s (i.e. the preset time threshold in the embodiment of the present application), the mobile terminal will resend the transmission data to the AR glasses until the AR glasses receive the ack information or the user actively stops sending the ack information.
In example two, as shown in fig. 3, a source service is established at a sending end of data, data to be transmitted (one or more of audio, video, configuration information, and the like) is compressed according to a compression coding format, and transmission data is generated and sent to a receiving end. The receiving end of the data establishes a sink service, receives the data from the wireless connection with the transmitting end, and analyzes the data according to the compression coding format of the transmission data. When the receiving end of the data returns ack information (configuration information, user operation information, and the like) after receiving the data, the sending end is allowed to confirm that the data is received, and the sending end is allowed to confirm whether the transmission data needs to be sent again. And when the transmitting end of the data receives the ack information, analyzing according to the coding format of the ack information, and correspondingly adjusting the transmission data. So as to reciprocate.
From the above description, it can be seen that the following technical effects are achieved by the present application:
in the embodiment of the application, data transmission interaction is performed between a sending end for establishing source service and a receiving end for establishing sink service, the data transmission is one or more of audio and video data, first configuration information data and control information data, the sending end can compress and encode the data transmission, the receiving end analyzes the data transmission according to the encoding mode of the sending end, and the analyzed data transmission is demonstrated and/or processed. Meanwhile, when the user configures and/or operates the transmission data, confirmation information corresponding to the transmission data is generated based on the configuration and/or operation of the user, and the confirmation information is sent to the sending end, so that the sending end can correspondingly adjust the transmission data according to the confirmation information. Compared with a streaming media transmission protocol in the related technology, the embodiment of the application increases the expansion of various data formats on the basis of transmitting videos through audio and video streaming media, and meanwhile, the interaction capacity of a data receiving end is emphasized. For the receiving end, after the user operates the transmission data at the receiving end, the user can also return the operation information to the transmitting end. And the technical problems that the audio and video of a receiving end cannot be directly operated and non-audio and video data cannot be sent by a mainstream audio and video transmission scheme in the related technology are solved.

Meanwhile, the data receiving end can transmit the configuration data and the user operation data to the transmitting end; the data sending end adjusts the sent data content according to the information sent by the receiving end.
The invention has the advantages that:
1) the sending end and the receiving end of the data can transmit the data in two directions;
