Document Type and Number:
WIPO Patent Application WO/2023/109156
Kind Code:
A1
Abstract:
Provided in the present application are a screen projection method and device, and a storage medium. The method is applied to a screen projection sending terminal, in which a screen projection application is installed. In a screen projection scenario, an audio device currently used by a screen projection sending terminal is acquired, and an identification number corresponding to the audio device is recorded in an audio state table, such that when it is determined that a sound output device selected by a user is a screen projection receiving terminal, audio data is acquired from the audio device identified by the identification number, rather than a default audio device such as a loudspeaker, and is then sent to the screen projection receiving terminal for playing, and therefore, it can be ensured that during a screen projection process, when the screen projection receiving terminal is the sound output device, the screen projection receiving terminal can always acquire audio data and thus play sound.
