Abstract

The invention discloses a low-delay Bluetooth audio signal transmission system and a low-delay Bluetooth audio signal transmission method. When the audio processing module detects that the Bluetooth audio device is started and is connected with the Bluetooth audio playing device, the low-delay Bluetooth audio transmission system provides information of the low-delay Bluetooth audio device to inform the application program. The audio processing module starts the low-delay Bluetooth audio device when the application program responds to and selects the low-delay Bluetooth audio device. The audio signal processing module only executes a fast audio signal processing program on an external audio signal received from the application program, and then transmits the external audio signal to the low-delay Bluetooth audio signal device. The low-delay Bluetooth audio device transmits an external audio signal to the Bluetooth audio device. And the Bluetooth audio device transmits an external audio signal to the Bluetooth audio playing device for playing.

Description

technical field [0001] The invention relates to bluetooth message transmission, in particular to a low-delay bluetooth message transmission system and method. Background technique [0002] In recent years, Bluetooth headsets have become popular in the market because they do not need to use a headset cable to connect to mobile phones, and are more convenient to wear than traditional wired headsets. However, currently on the market, mobile phones such as Android phones play audio through Bluetooth headsets. Compared with the speaker of the phone itself, the delay The time has increased significantly, causing the audio and video to be out of sync when watching videos on mobile phones. There are also many games such as simulated musical instruments or drumming games that have poor operating experience. [0003] The audio delay of the mobile phone playing via the Bluetooth headset is mainly caused by three parts: the mobile phone audio playback system, the Bluetooth communication...
