Abstract

The invention discloses a multimedia synchronization method, a player and a multimedia data making device, wherein the multimedia synchronization method comprises the following steps: establishing an event index that corresponds to the position of a preset frame in an audio data stream and establishing an association between the event index and a synchronous file, wherein the event index or the synchronous file and the audio data stream are respectively positioned in different files; playing audio data and monitoring whether the played schedule reaches the position of the preset frame that corresponds to the event index in the audio data stream or not; finding out and playing the corresponding synchronous file of the event index according to the association when the played schedule reaches the position of the preset frame that corresponds to the event index in the audio data stream. The invention can not only satisfy the requirements of multimedia synchronization, especially the electronic book data synchronization, but also is easy to develop and manage.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a multimedia synchronization method, a player and a multimedia data production device. Background technique [0002] In the field of multimedia playing technology, it is an important technology in this technical field to present more than two kinds of media content to users at the same time, so that users can appreciate rich and colorful media information. Corresponding to the playback of voice media, it is generally necessary to realize the synchronization of voice and text or images. [0003] A prior art synchronization technology for audio books is the synchronization technology used by MP3 Lyrics or Karaoke systems. In this technique, to achieve the figure 1 The sound shown is synchronized with the text. Generally, it is necessary to generate an additional time data file to specify the text related to the audio. The time value at which each paragraph of text appears is marked in ...
