Abstract

Disclosed is a synchronization method of an accompaniment, a voice and a subtitle for on-line karaoke. The voice and the accompaniment are mixed at a singer end and sent to a streaming media server after adding a played time stamp and encoding; at a listener end, after a streaming media player thread is started, a lyric is loaded first from the server, then streaming media data are received, subtitle play is synchronized by using the received streaming media data volume, and synchronization of the accompaniment, the voice and the subtitle for the karaoke at the listener end and the singer end is achieved. According to the method, network bandwidth live transmission is reduced, and the lyric is completely loaded from the server before the streaming media play thread at the receiver end is started; and simultaneously, computation consumption of the CPU is reduced, the voice and the accompaniment are mixed at the singer end and the play time is added for compressed encoding to form a multimedia data block, decoding play is performed at the receiver end, and the subtitle is synchronized according to the play data volume.
