Abstract

The invention discloses an audio packet loss data receiving method and device, audio playing equipment and a system. The method comprises the steps of: when second audio playing equipment does not successfully receive current audio data sent by sound source equipment, sending prompt information indicating that the current audio data is not successfully received to first audio playing equipment; receiving an error correction data packet forwarded by the first audio playing equipment in a preset frequency band through using a first link, and during the period, receiving current audio data retransmitted by the sound source equipment in the same preset frequency band through using a second link; comparing the signal power intensity of the data received by the first link with the signal power intensity of the signal received by the second link; and selecting to demodulate the data received through the first link or demodulate the data received through the second link, and performing error correction on the current audio data. The data can be received through using a better link, the bandwidth efficiency is improved, and better robustness and performance are achieved.

Description

technical field [0001] The present invention relates to the technical field of audio communication, in particular to an audio packet loss data receiving method, device, audio playback device and system. Background technique [0002] True Wireless Stereo (TWS) is very popular these days. This is because TWS realizes the wireless transmission between the two earbuds and the mobile phone, which brings great convenience to consumers. Before the BLE 5.2 protocol, in the Bluetooth protocol, it was impossible for a mobile phone to connect to two headsets at the same time. In this case, in the Bluetooth protocol, the industry generates different proprietary protocols to implement TWS, such as sniffing, basic relay, and dual advanced audio distribution profile (Dual-a2dp). However, none of these techniques can completely overcome the serious threat of deep fading caused by human body to the stability of TWS in wireless environment. [0003] In the past, please refer to figure 1 ,...
