Referring to fig. 1, fig. 1 is a schematic structural diagram of a data transmission system according to an embodiment of the application. The data transmission system may include at least one transmitting end 1000 and at least one receiving end 2000.
Wherein the transmitting terminal 1000 may be connected to different receiving terminals 2000 through a network. The transmitting end 1000 and the receiving end 2000 may be electronic devices having computing hardware capable of supporting and executing software products corresponding to multimedia. The network may be a wireless network or a wired network, for example, the wireless network may be a Wireless Local Area Network (WLAN), a Local Area Network (LAN), a cellular network, bluetooth, a 2G network, a 3G network, a 4G network, a 5G network, or the like.
In the embodiment of the present application, the transmitting end 1000 and the receiving end 2000 are connected to each other through UWB. The transmitting end 1000 is a UWB transmitting device, and the receiving end 2000 is a UWB receiving device. The UWB transmitting device and the UWB receiving device may be electronic devices having UWB functions.
In a specific implementation process, the transmitting end 1000 is configured to transmit a data packet to the receiving end 2000, and the receiving end 2000 is configured to receive the data packet transmitted by the transmitting end 1000 and feed back acknowledgement information to the transmitting end 1000.
In some embodiments, the transmitting end 1000 may be configured to acquire audio data, and then segment the audio data to generate a plurality of data packets arranged according to time sequence. And then, carrying out data processing on the current first data packet to generate a target data packet. Then, the transmitting end 1000 transmits the target packet to the receiving end 20000. It should be noted that the target data packet includes time information of the current first data packet and the current second data packet.

Referring to fig. 2, fig. 2 is a flow chart of a data transmission method according to an embodiment of the application. It should be noted that, the data transmission method is applied to the transmitting end, and the specific flow of the data transmission method may be as follows:
101. and acquiring current source data.
In the embodiment of the present application, the current source data is audio data. The audio data refers to data transmitted through an audio manner. It should be noted that the audio data includes, but is not limited to, original lossless audio recorded in real time for an audio recording device having a networking function.
The audio recording device can be integrated in the transmitting end, and the transmitting end can directly acquire the audio data through the audio recording device. The audio recording device may also be a device independent of the transmitting end, and the audio data may be acquired by the audio recording device, and then the transmitting end acquires the audio data from the audio recording device through data interaction.
102. And dividing the current source data into at least two data packets, and caching according to the time sequence.
In some embodiments, the current source data may be randomly segmented to obtain a plurality of data packets with equal or unequal data packet lengths, and then compressing each data packet according to a first target compression ratio, and buffering the compressed data packets according to a time sequence.
It can be understood that, in the embodiment of the present application, the current source data is audio data, so that each data packet obtained by slicing has a corresponding timing sequence. In the specific implementation process, each data packet can be sequentially stored in the corresponding buffer area according to the sequence of the time sequence. For example, a data packet with a first time sequence is stored in the first buffer, a data packet with a second time sequence is stored in the second buffer, and a data packet with a third time sequence is stored in the third buffer.
The timings of the first timing, the second timing, and the third timing are sequentially increased. When the transmitting end transmits the data packets, the data packets of the first buffer area, the data packets of the second buffer area and the data packets of the third buffer area are sequentially transmitted according to the sequence.
103. And acquiring time information of a current second data packet, wherein the current second data packet is the next data packet arranged in the current first data packet.
Specifically, the packet length of the current second packet may be obtained; and acquiring time information of the current second data packet according to the length of the data packet.
In some embodiments, time information of a large number of data packets with different data packet lengths may be sampled in advance, then a data lookup table is constructed according to a correspondence between the data packet lengths and the time information, and then the data packet lengths may be input into the data lookup table for matching, so as to obtain corresponding time information.
It will be appreciated that the current first data packet refers to the data packet of the first current timing and the current second data packet is the data packet of the second current timing.
The time information includes a transmission preparation time and an air transmission time.
104. And carrying out data processing based on the time information and the current first data packet to generate a target data packet.
Specifically, the transmission preparation time and the air transmission time can be encapsulated to generate the identification information; and combining the identification information with the current first data packet to generate a target data packet.
In the embodiment of the present application, the identification information is header (header) information, that is, information placed at the header of the data packet.
105. When receiving the data sending instruction, the target data packet is sent to the receiving end, so that the receiving end adjusts the receiving time sequence of the next data packet according to the time information.
When the sending preparation time of the target data packet arrives, the sending end receives a data sending instruction to instruct the sending end to send the target data packet, so that the receiving end adjusts the receiving time sequence of the next data packet according to the time information, that is, the sending time sequence of the sending end is aligned with the receiving time sequence of the receiving end, thereby saving the total time required by data transmission and improving the data transmission efficiency.
In some embodiments, after the destination packet is sent, the sender may prepare to send the next packet. That is, after the transmission of the target packet is completed, step 103 may be performed back until all packets are transmitted.
In another embodiment, after the receiving end receives the target data packet, the receiving end generates corresponding acknowledgement information and feeds the acknowledgement information back to the sending end. The sending end can judge the current transmission condition by counting the confirmation information of the receiving end in a preset time period, so as to confirm whether the data packet length of the rest data packets needs to be adjusted. The acknowledgement information carries the first transmission efficiency of the target data packet.
In the implementation process, after the receiving end receives the confirmation information, the second transmission efficiency of the target data packet can be obtained, so as to judge whether the first transmission efficiency is consistent with the second transmission efficiency, and confirm whether the data transmission efficiency reaches the best.
Specifically, after step 105, it may further include: when acknowledgement information fed back by a receiving end is received, acquiring first transmission efficiency and second transmission efficiency of a target data packet; comparing the first transmission efficiency with the second transmission efficiency, and confirming whether to adjust the data packet length of the rest data packets according to the comparison result; and after the data packet length of the remaining data packets is adjusted or when the data packet length of the remaining data packets is determined not to be adjusted, returning to the step of acquiring the time information of the current second data packet until all the data packets are transmitted.
The first transmission efficiency is a target data transmission efficiency calculated by the receiving end according to the receiving period of the target data packet, the size of the data packet, the index continuity in the identification information, and the like. The second transmission efficiency is the data transmission efficiency of the transmitting end itself.
It will be appreciated that when the first transmission efficiency and the second transmission efficiency are consistent, the data transmission efficiency between the receiving end and the transmitting end is optimal, and the data packet length of the remaining data packets is not required to be adjusted at this time, and the process may directly return to the execution step 103. When the first transmission efficiency and the second transmission efficiency are inconsistent, the data transmission efficiency between the receiving end and the transmitting end is not optimal, at this time, the inconsistent times may be counted, and when the inconsistent times reach the threshold value, the packet length of the remaining packets is adjusted, and after the packet length of the remaining packets is adjusted, the execution returns to step 103.
That is, when the number of times that the first transmission efficiency and the second transmission efficiency are inconsistent does not reach the threshold, the step 103 may be executed directly without adjusting the packet length of the remaining packets.
It should be noted that, the threshold may be set according to practical situations, which is not limited by the embodiment of the present application. For example, the threshold may be 1, 2, 3, 4, 5, etc.
It can be understood that in the specific implementation process, the length of the data packet can be adjusted by decompressing or recompressing the remaining data packet according to the second target compression ratio, so that the dynamic adjustment of the compression ratio of the data packet according to the current transmission condition is realized, the flexibility of data transmission is improved, a plurality of data packets can be transmitted in time, the efficiency of data transmission is improved, and the problem of lower data transmission efficiency in the related art is further solved.
It should be noted that the compression ratio includes, but is not limited to, a compression format. That is, when compressing or decompressing the data packet, the compression format used is adjusted so as to realize a target compression format (having a target compression ratio) in which the compression ratio is determined to be appropriate for the current transmission condition by employing a different compression format.
In summary, the data transmission method provided by the embodiment of the application includes obtaining current source data; dividing current source data into at least two data packets, and caching according to time sequence; acquiring time information of a current second data packet, wherein the current second data packet is the next data packet arranged in the current first data packet; performing data processing based on the time information and the current first data packet to generate a target data packet; when receiving the data sending instruction, the target data packet is sent to the receiving end, so that the receiving end adjusts the receiving time sequence of the next data packet according to the time information. According to the scheme, the time information of the current second data packet can be acquired before the current first data packet is transmitted, the target data packet is generated according to the time information and the current first data packet, and then the target data packet is transmitted to the receiving end, so that the receiving end adjusts the receiving time sequence of the next data packet according to the time information, the transmitting time sequence of the transmitting end is aligned with the receiving time sequence of the receiving end, the total time required by data transmission is saved, and the data transmission efficiency is improved.
Referring to fig. 3, the embodiment of the present application further provides another data transmission method, which needs to be described, and the specific flow of the data transmission method is as follows:
201. And receiving the target data packet sent by the sending end.
202. And acquiring the identification information of the target data packet.
203. And de-encapsulating the identification information to generate time information of the target data packet.
204. And adjusting the receiving time sequence of the next data packet according to the time information so as to align the receiving time sequence of the next data packet with the transmitting time sequence of the transmitting end.
In some embodiments, after the receiving end receives the target data packet, the receiving end generates corresponding acknowledgement information and feeds the acknowledgement information back to the sending end. The sending end can judge the current transmission condition by counting the confirmation information of the receiving end in a preset time period, so as to confirm whether the data packet length of the rest data packets needs to be adjusted. The acknowledgement information carries the first transmission efficiency of the target data packet. That is, after step 104, it may further include:
generating confirmation information and feeding back the confirmation information to the transmitting end.
The first transmission efficiency is a target data transmission efficiency calculated by the receiving end according to the receiving period of the target data packet, the size of the data packet, the index continuity in the identification information, and the like.
In summary, the data transmission method provided by the embodiment of the application includes receiving a target data packet sent by a sending end, obtaining identification information of the target data packet, performing decapsulation processing on the identification information, generating time information of the target data packet, and adjusting a receiving time sequence of a next data packet according to the time information so as to align a receiving time sequence of the next data packet with a sending time sequence of the sending end.
