Abstract

The invention relates to a screen projection method. The method comprises the following steps: sending a request for obtaining a screen projection code; receiving a screen projection code which responds to the request and is associated with the terminal, wherein the screen projection code comprises characters; determining a frequency point sequence obtained by mapping the screen projection code according to a mapping relationship between characters and frequency points; playing an audio sequence corresponding to the frequency point sequence, wherein the played audio sequence is used for indicating screen projection equipment to identify the screen projection code according to the received audio sequence, and the identified screen projection code is used for establishing screen projection connection between the associated terminal and the screen projection equipment. According to the scheme provided by the invention, the application range of the projection screen is greatly widened.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a screen projection method. Background technique [0002] With the development of computer technology, computer devices such as mobile phones, tablet computers and notebook computers have become an indispensable part of people's daily life and work. At present, in many scenarios, such as teaching or multi-person conferences, it is necessary to display relevant content through a large-sized display screen, so that participants can easily watch the content they intend to watch. [0003] In traditional technology, screen projection is usually performed through wired projection. The limited projection method limits the distance between the user terminal and the projection device to a relatively small distance. Furthermore, whether the effective connection between the user terminal and the projection device is still uncertain. It is limited by the interface specifications of the us...
