Synchronization method of accompaniment, voice and subtitle for on-line karaoke

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.

Description

Problems solved by technology

On the one hand, due to the influence of the operator's network, the bandwidth of the mobile Internet is far less than that of the traditional Internet. During multi-channel data transmission, data delays are often caused, and either only the accompaniment is heard, or only the human voice is heard, or only the human voice is seen. progressive subtitles

On the other hand, the CPU performance of small devices such as mobile terminals cannot be compared with that of PCs. Using multiple channels of data to play and synchronize with each other at the same time requires high computing power of the CPU, which will cause stuttering and poor user experience.
