Title:
AUDIO DATA SENDING AND RECEIVING METHOD AND TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/114469
Kind Code:
A1
Abstract:
The present invention relates to an audio data sending and receiving method and device and a transmission system. The wireless audio data transmission system comprises a wireless microphone and a wireless audio receiver. The wireless microphone sets an output delay according to a wireless environment state, and sends the audio data according to the output delay; and the wireless audio receiver stores the audio data into a cache according to the output delay set according to the wireless environment state, and outputs the audio data upon the arrival of the output delay. Due to the fact that the output delay can be flexibly adjusted according to the wireless environment state, wireless redundant bandwidth is fully utilized and the number of times of sending, receiving and transmitting the audio data in the output delay is effectively increased, such that the success rate of the sending, receiving and transmitting processes of the audio data can be increased and packet loss rate is reduced; thus the adaptability of a product to different wireless environments can be improved, thereby improving the uninterrupted level of audio continuous output.
