Abstract

The invention relates to the field of data screen projection, and discloses a screen projection method, device, equipment and storage medium based on the mDNS protocol. The method includes: acquiring a preset screen projection display device and sending screen projection verification information based on the mDNS protocol, wherein the screen projection verification information includes: an identifier of the screen projection display device; outputting the screen projection verification information to In the preset display port; receive the device selection instruction, and the projection request for obtaining the target data, and send the target data to the identifier; judge whether the projection display device has completed the reception of the target data; If the above object data is received, the device selection command is reset to receive a new device selection command.

Description

technical field [0001] The present invention relates to the field of data screen projection, in particular to a screen projection method, device, equipment and storage medium based on the mDNS protocol. Background technique [0002] In the information age, the speed of data transmission is getting faster and faster, from the original 3G transmission network to the current 4G transmission network, and the 5G transmission network that is being popularized. The way and method of data transmission is constantly being updated, and the close excuse of theory and experiment makes the communication transmission network faster and faster. In the field of basic research, it is found that Polar code directly affects the transmission speed of the entire communication field. [0003] At the application level, the principle of screen projection will also affect the speed of screen projection. When the projection data changes little, there is not much difference between different project...
