AI Technical Summary

Technical Problem

In existing technologies, there are problems such as inaccurate switching, high latency, weak anti-interference ability, and playback stuttering during the switching process between Bluetooth audio and WiFi audio. This is especially true when the network environment is poor or the audio stream is lost, which affects the continuity and stability of audio playback.

Method used

Employing a dual-link parallel transmission method, the stereo audio stream is mixed to generate a hybrid audio stream, and square wave signal data is generated based on the transmission information of the hybrid audio stream. This enables precise matching and switching of audio frame pairs, ensuring seamless switching to another connection for playback.

Benefits of technology

It improves the accuracy and reliability of audio link switching, reduces latency and playback stuttering, enhances the system's anti-interference ability, ensures the smoothness and continuity of audio playback, and improves the user experience.

Abstract

This disclosure relates to the field of communication and interaction technology, specifically to an audio transmission method, an audio transmission device, and an audio transmission system. The audio transmission method applied to the transmitting end includes: acquiring a stereo audio stream; mixing a first-channel audio stream and a second-channel audio stream to obtain a mixed audio stream for the first channel processing at the receiving end; determining square wave signal data corresponding to the mixed audio stream based on the transmission information of each audio frame in the mixed audio stream, for the second channel processing at the receiving end; combining the mixed audio stream and the square wave signal data, and transmitting the combined data via a first connection and a second connection pre-established with the receiving end, respectively, so that the receiving end can switch between the first audio stream received via the first connection and the second audio stream received via the second connection, thereby improving switching accuracy, reducing switching latency, and ensuring the smoothness and continuity of audio playback.
