Embodiment 1
[0060] Figure 4 It is a schematic flowchart of an audio-video synchronization method provided in Embodiment 1 of the present invention, as shown in image 3 As shown, the method mainly includes the following steps:
[0061] Step 301, receiving multimedia information broadcast by the main player from the player, wherein the multimedia information includes video synchronization information and source identification information;
[0062] Step 302, judging from the player whether this machine is playing the video according to the source identification information, if the currently played video is identical to the source identification information broadcast by the master player, step 303 is performed, otherwise step 304 is performed;
[0063] Step 303, calculating from the player the first difference between the first time point of the current playback of the video played by the player and the synchronization information domination time of the master player;
[0064] Step 304, i...
Embodiment 2
[0070] Figure 5 A schematic diagram of a method for synchronizing audio and video frames using a time axis provided in Embodiment 2 of the present invention, as shown in Figure 5 As shown, the method mainly includes the following steps:
[0071] Step 401, obtaining the second time point of the decoded audio and video frame from the player;
[0072] Step 402, calculate the second difference between the second time point and the third time point currently played on the time axis in the player synchronization module, if the second difference is less than the set output threshold, then execute step 403, otherwise Execute step 404;
[0073]Step 403, calculate the third difference of the third time point minus the second time point, if the third difference is greater than the set delay time, then execute step 406, otherwise execute step 405;
[0074] Step 404, wait for a period of time and re-execute step 401;
[0075] Step 405, output the audio or video frame of the currently...
