Embodiment Construction

[0076] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0077] Such as figure 1 As shown, in one embodiment, a system time calibration method based on audio synchronization is provided, the method includes the following steps:

[0078] Step 101, establish a connection with the audio player through a wireless network.

[0079] In this embodiment, the wireless audio device includes an audio server and an audio player that generate audio sources. The audio player establishes a connection with the audio server through a wireless network. For example, in a home video system, the audio player can be a wireless stereo, and the server that provides the audio...

Abstract

The invention provides an audio synchronous playing-based system time calibration method, an audio synchronous playing method and devices. The audio synchronous playing-based system time calibration method includes the following steps of: building a network connection with an audio player through a wireless network; calibrating the first system time of the audio player and returning the calibrated first system time to the audio player; sending audio data to the audio player; sending a playing control instruction to the audio player; obtaining the first system time of the audio player according to preset time intervals; and calibrating the first system time again according to the difference of the first system time and a second system time, and returning a calibration result to the audio player. With the methods and the devices adopted, the synchronous playing effect of the audio player can be improved.

Description

technical field [0001] The invention relates to the technical field of multimedia playback, in particular to a system time calibration method based on audio synchronous playback, an audio synchronous playback method and a device. Background technique [0002] Since wireless audio equipment does not require wiring and is free from the constraints of wires, it can be placed in various locations at will, which brings great convenience to users. For example, the wireless audio device is a home audio-visual system, and the user can play the same music in multiple rooms at the same time, or play different music in each room. A wireless audio device includes an audio server that generates sound sources and an audio player that plays sounds. In order to ensure synchronous audio playback, the audio server needs to calibrate the system time in the audio player connected to it before sending audio data. [0003] The traditional system time calibration method can only be calibrated be...
