Abstract

The invention discloses a synchronous audio playing method, apparatus and system. The method comprises the following steps: obtaining the network transmission quality between a master control playing device and slave playing devices in a plurality of playing devices to obtain multiple network transmission quality, sorting the multiple network transmission quality to obtain a sorting result, and determining synchronous playing devices in the plurality of playing devices according to the sorting result and a preset playing number. The synchronous playing devices are automatically determined according to the dynamic change of the network transmission quality, thereby obtaining the optimal synchronous playing result, and reducing the energy consumption of a synchronous playing system while ensuring excellent user experience.

Description

technical field [0001] The present invention relates to the technical field of multimedia playback, in particular to an audio synchronous playback method, device and system. Background technique [0002] Multiple playback devices (such as mobile phones, computers, speakers, various players, etc.) are connected through wired or wireless network technology to form a multimedia synchronous playback system, which plays the same audio, video or picture synchronously, which has been widely used. Taking the audio synchronous playback system as an example, how to realize the synchronous playback of multiple playback devices, so that the sound delay between multiple devices is as small as possible, so as to ensure the consistency of the user's sense of hearing, is the key technology for multi-device synchronous playback . [0003] For example, when multiple playback devices play music synchronously, one of the playback devices acts as the master playback device, and the master playb...
