Bluetooth transmission data playing method and device and Bluetooth transmission data sending method and device

Abstract

The invention relates to a Bluetooth transmission data playing method and device and a Bluetooth transmission data sending method and device. The Bluetooth data playing method is applied to receivingequipment, the receiving equipment is in Bluetooth connection with a sending device. The method comprises the steps that: an independent data receiving thread receives a data packet sent by a sendingdevice and stores the data packet in a buffer storage area of a receiving device, the data packet comprises a data packet at the current playing position and a data packet after the current playing position, and the data packet is audio data and / or video data; the data packet is played. By caching the data packet at the current playing position and the data packet which is not played after the current playing position, the playing delay is reduced, the playing synchronization between the receiving device and the sending device is ensured, and when the Bluetooth signal is not good, the receiving device can still maintain normal playing, so that sound interruption and jamming are avoided, and the user experience is improved.

Description

Technical field [0001] The present disclosure relates to the field of data transmission, and in particular to a method for playing Bluetooth data transmission, a device for playing Bluetooth data, a method for sending Bluetooth data, a device for sending Bluetooth data, electronic equipment, and a computer-readable storage medium. Background technique [0002] Bluetooth (Bluetooth) is a wireless technology standard that can realize short-distance data exchange between fixed devices, mobile devices and building personal area networks (using UHF radio waves in the 2.4-2.485 GHz ISM band). In the current Bluetooth data transmission, when the Bluetooth signal is poor, the playing fluency of multimedia data by the receiving device will be affected. When the distance between the sending device and the receiving device is relatively long, or the electromagnetic interference in the wireless transmission environment is strong, the music playback of the receiving device will experience int...

AI Technical Summary

Problems solved by technology

Once the wireless transmission signal becomes poor, the receiving device cannot receive more audio data in time, and all the audio data in the buffer storage area will be played, and there will be no remaining audio data, and the receiving device will break the sound

[0005] In addition, when the current Bluetooth playback device is playing, it needs to wait to receive the data currently being played, and then play it after the buffer memory is full, resulting in the playback progress of the Bluetooth device relative to the control device (such as a smart mobile terminal or PC). There is a certain delay in the playback progress, ranging from tens of milliseconds to hundreds of milliseconds. The playback of the two devices is out of sync, which affects the user experience
