Abstract

The invention discloses a data transmission method, and the method comprises the steps: receiving a screen projection request of a screen projection terminal, and building an audio and video data connection channel with the screen projection terminal; acquiring audio and video data through the audio and video data connection channel and playing the audio and video data; monitoring the network state of the audio and video data connection channel; and when the network state becomes poor, selecting and executing a corresponding transmission mode from a preset transmission strategy according to the index value of the network state. The invention further provides a data transmission device, computer equipment and a computer readable storage medium. According to the invention, a proper transmission mode can be dynamically selected according to the index value of the network state, so that the problems of time delay and jamming are solved, and a display effect is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a data transmission method, device, computer equipment, and computer-readable storage medium. Background technique [0002] With the development of computer technology, more and more types of electronic devices have been developed and widely used. All kinds of electronic devices generally have their own characteristics. For example, mobile phones are more portable, TV screens have better display effects, and speakers have better sound quality. In order to give full play to the device characteristics of different electronic devices, the electronic device can realize the switching and display of display content among multiple devices through methods such as screen projection. In the prior art, during the screen projection display process, delays and freezes often occur, and the display effect is poor. Contents of the invention [0003] The present application...
