Problems solved by technology

[0003] However, the projected device may be connected to multiple projected devices. When the projected device outputs the images and sounds of other projected devices, the transmission channel between the projected device and the projected device has not been disconnected. , the screen and sound on the screen-casting device will still be transmitted to the screen-casting device, making it impossible to output sound on the screen-casting device

Abstract

The invention discloses an intelligent control method and device and electronic equipment. The method comprises the steps of sending display data and audio data to screen projection equipment in real time by a data channel connected with the screen projection equipment; monitoring the state of the data channel and the output state of the audio data on the screen projection equipment; and if the state of the data channel is a connection state and the output state of the audio data in the screen projection equipment is a non-effective output state, controlling the audio data transmitted in real time to be switched to play equipment for output.

Description

technical field [0001] The present application relates to the technical field of screen projection, and in particular to a control method, device and electronic equipment. Background technique [0002] In order to realize screen expansion, screen projection technology is mostly used at present to output the screen and sound of the screen projection device to the screen-projected device, and the screen-projected device outputs the screen and sound. [0003] However, the projected device may be connected to multiple projected devices. When the projected device outputs the images and sounds of other projected devices, the transmission channel between the projected device and the projected device has not been disconnected. , the screen and sound on the screen-casting device will still be transmitted to the screen-casting device, making it impossible to output sound on the screen-casting device. Contents of the invention [0004] In view of this, the application provides an in...
