[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...

The invention discloses an audio transmission method, which comprises the following steps: when playing a video, obtain the PCM data packet of the audio data in the audio and video stream of the video in real time, and send the PCM data packet to the local device wirelessly connected WiFi speaker, then detect whether the WiFi speaker is in the ready state for work, and finally if the WiFi speaker is in the ready state for work, then send the preset sound delay value to the WiFi speaker so that the local device can play the When the video picture of the video is described, the WiFi speaker performs delay control on the output time of the PCM data packet according to the sound delay value, so as to realize the synchronization of the audio data corresponding to the video picture and the PCM data packet. The invention also discloses an audio transmission device, equipment and a readable storage medium. The present invention avoids the problem of out-of-sync sound and picture caused by sound delay caused by WiFi transmission, thereby improving the efficiency of sound and picture synchronization.
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...
