Embodiment 1

[0045] see figure 1 , figure 1 It is a simplified flowchart of Embodiment 1 of the data transmission method provided by the present invention.

[0046] The data transfer method includes:

[0047] S100. Obtain the sending time and receiving time of the received data packet.

[0048] Specifically, when the data packet receiving end communicates with the data packet sending end and performs real-time data transmission, it is the data packet sending end that will need to transmit data, such as audio frames, video frames, etc., to perform encoding, compression, and other processing, Form a data packet and send it to the data packet receiving end. After receiving the data packet, the data packet receiving end performs decompression, decoding and other processing to obtain audio frames, video frames and other data, and then performs frame processing to realize audio and video playback. The transmission between the sending end of the data packet and the sending end of the data pack...

Embodiment 2

[0122] Based on the above embodiments, the present invention also provides a terminal, the functional block diagram of which can be as follows Figure 4 shown. The terminal includes a processor, a memory, a network interface, a display screen and a temperature sensor connected through a system bus. Wherein, the processor of the terminal is used to provide calculation and control capabilities. The memory of the terminal includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The network interface of the terminal is used to communicate with external terminals through a network connection. When the computer program is executed by the processor, a data transmission method is realized. The display screen of the terminal may be a liquid crystal disp...

Abstract

The invention discloses a data transmission method, a terminal and a storage medium, and the method comprises the steps: obtaining the transmission time and receiving time of a received data packet capable of reflecting a network load condition to generate a transmission rate adjustment instruction which comprises a transmission rate adjustment strategy used for adjusting the transmission rate of the data packet, so that the data packet sending end adjusts the data packet sending rate according to the sending rate adjustment strategy, the dynamic adjustment of the data packet sending rate according to the network load condition is realized, the network load is prevented from being further increased when the network load is large, and the audio and video quality is ensured.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data transmission method, a terminal and a storage medium. Background technique [0002] At present, end-to-end real-time data transmission services are very common. For example, when people are making voice calls and videos over the Internet, they need to process the data at the sending end into data packets in real time and then transmit them to the receiving end through the network in real time. Decoding and other processing of data packets presents the data to the user. In the prior art, the sender sends data packets according to the preset sending rate. When the network load is relatively high, there will be data packet delay and packet loss, and continuing to maintain a high sending rate will further The network load is increased, forming a vicious circle, and the delay rate and packet loss rate are further increased, affecting the quality of audio and vi...
