Problems solved by technology

[0004] However, in the current multi-screen projection scenario, the audio data of each terminal is basically sent to the large-screen display device for simultaneous playback, resulting in mixed audio played by the large-screen display device, and users cannot capture the audio they want, resulting in Poor screen effect, poor user experience

Abstract

The application discloses a method and a device for processing audio data in a many-to-one projection system. During the many-to-one screen projection, each electronic device can play its own audio and / or the audio of other electronic devices according to user needs, so as to meet the needs of different users in the many-to-one screen projection scenario. When the electronic device mixes its own audio and the audio of other electronic devices and plays it, the user can hear the audio of all electronic devices at the same time. In the game scene, users can not only feel their own game scene, but also feel the game scene of other users, which can improve user experience.

Description

technical field [0001] The present application relates to the technical field of screen projection, and in particular to a method, device and system for processing audio data in many-to-one screen projection. Background technique [0002] With the development of terminal technology, more and more terminals have a screen projection function. For example, one or more mobile phones can project the currently displayed picture to a large-screen display device such as a TV for display. Projecting a screen from one terminal to a large-screen display device can be called one-to-one screencasting; casting multiple terminals to a large-screen display device at the same time can be called many-to-one screencasting. [0003] In the case of many-to-one projection, the large-screen display device can display images from multiple terminals in different areas, and multiple users can see their own terminal images on the large-screen display device at the same time, which provides a better u...
