Embodiment Construction

[0106] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0107] In each embodiment of the present invention, the first device can be a large-screen device such as a smart TV, and the second device can be a device such as a mobile phone. Using the system recording function of the smart TV or set-top box, the audio data obtained by recording is encoded and passed through The wireless network is sent to the mobile phone, and the mobile phone decodes it. At the same time, the delay time of the entire audio return playbac...

Abstract

An embodiment of the invention provides a cross-device audio / image synchronous playing method, equipment and system. A first device acquires audio data in the local and sends the audio data to a second device for playing, and acquires audio delay time. When the audio delay time is out, images corresponding to the audio data are displayed. System recording for is utilized for acquiring the audio data, the audio data of a TV-end device is sent back to a device such as a cell phone for playing and delay time for audio play is obtained. After the audio delay time is out, the images are displayed. In this way, synchronous playing of audio and images among different devices is realized.

Description

technical field [0001] The present invention relates to the technical field of audio image synchronization, in particular to a method, device and system for synchronously playing audio images across devices. Background technique [0002] Watching videos on large-screen devices such as smart TVs or set-top boxes is becoming increasingly popular. However, in some occasions, for example, to avoid affecting other people's work or study, users need to play the audio on the large-screen device through other devices such as headphones. [0003] In the prior art, the audio on the large-screen device is usually played directly through a wired connection or other devices such as Bluetooth. However, for the user, the direct wired connection is limited by the length of the line when using it, which is very inconvenient to use. Bluetooth devices have hardware limitations. Therefore, there is an urgent need to provide a simple and universal method for synchronously playing audio and imag...
