[0089] Based on the first embodiment, a second embodiment of the audio transmission method of the present invention is proposed. In this embodiment, step S30 includes:

[0090] Step S31, if the WiFi speaker is in the ready state, obtain the change state of the TV source, and determine whether the TV source switches signal modes based on the change state;

[0091] In this embodiment, the user can switch the TV source of the TV through the controller (for example, a remote control, a mobile phone). When the user switches the TV source, the signal mode of the TV source will change, and the TV signal mode of different signal modes The sound delay value corresponding to the source can be different. Therefore, when the WiFi speaker is detected to be in the ready state, the change state of the TV source is monitored. When the state of the TV source changes, a notification event will be sent to the Handle_Control sub Module, the TV source notification event can be monitored in real ti...

Abstract

The invention discloses an audio transmission method. The method comprises the following steps of obtaining a PCM (Pulse Code Modulation) data packet of audio data in audio / video streams of a video inreal time when the video is played, and sending the PCM data packet to a WiFi sound box wirelessly connected with local equipment; detecting whether the WiFi sound box is in a working ready state ornot; and sending a preset audio delay value to the WiFi sound box if the WiFi sound box is in the working ready state, thereby enabling the WiFi sound box to carry out delay control over output time of the PCM data packet according to the audio delay value when the local equipment plays video images of the video, and realizing synchronization of the video images and the audio data corresponding tothe PCM data packet. The invention discloses an audio transmission device and equipment and a readable memory medium. According to the method, the device, the equipment and the readable memory medium, the problem that audios and images are asynchronous due to audio delay resulting from WiFi transmission is avoided, and audio and image synchronization efficiency is improved.

Description

technical field [0001] The present invention relates to the field of audio transmission, in particular to an audio transmission method, device, equipment and readable storage medium. Background technique [0002] With the continuous improvement of the transmission performance and stability of WIFI and the one-to-many connection design of WIFI speakers compared with Bluetooth and other 2.4G speakers, the superior transmission capacity and simple operation and other advantages, WIFI speakers will become more and more popular in the audio terminal product market. More and more attention and popularity, and TV as the center of home audio-visual equipment, WIFI speakers are likely to become a must-have peripheral audio sharing and listening device. [0003] At present, smart TVs generally have a WIFI connection function, and the use of TV WIFI is connected to the home WIFI router. The user only needs to connect the WIFI speaker to the WIFI router, so that it and the TV are in the...
