Abstract

The invention discloses a convenient and fast video screen projection method compatible with multiple applications, and the method comprises the steps: installing a screen projection application in a mobile terminal, developing a screen projection service in the screen projection application, transmitting screen projection data to the screen projection application when the application of the mobile terminal needs screen projection, and enabling the screen projection service to judge whether the screen projection type is a supported screen projection type or not, and if yes, starting to search equipment capable of realizing screen projection so as to realize screen projection. By utilizing the method, the screen projection function does not need to be developed for each application, the screen projection requirements of each application of the mobile terminal can be realized only by installing one screen projection application in the mobile terminal, and the method and the device are easy to realize and high in practicability.

Description

technical field [0001] The invention relates to the technical field of video screen projection, in particular to a method for conveniently compatible with multiple applications for video screen projection. Background technique [0002] With the popularization of smart mobile devices, people watch videos on the mobile terminal very frequently, but the screen of the mobile terminal is generally relatively small, which will damage the vision for a long time. Currently, the video from the mobile phone can be cast to the TV for playback through the DLNA protocol. However, many video software do not provide the function of screen projection. The main reason is that each application needs to perform the screen projection function, which is time-consuming and expensive. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the present invention aims to provide a method for video projection that is convenient and compatible with multiple applica...
