Wireless digital television screen projection method and device, computer equipment and storage medium

Abstract

The invention relates to a wireless digital television screen projection method and device, computer equipment and a storage medium, and the method comprises the steps: connecting wireless digital television equipment WiFi through a control terminal, and receiving video information; receiving a screen projection request input by a user through the terminal; establishing a temporary media stream storage pool and an http protocol access link according to the screen projection request; sending the http protocol access connection to a screen projection player; and finally, projecting the video information to the projection screen player through the temporary media stream storage pool and the http protocol access link. According to the method, the DLNA screen projection protocol requirement is met by establishing the temporary storage pool and constructing the http media transmission protocol, so that the television content of the wireless digital television equipment is projected from a mobile phone end to screen projection terminals such as a television, a tablet computer and a screen projector to be played; and the screen projection function of the portable wireless digital television is realized.
