Edit system and method for multimedia synchronous broadcast

Abstract

The invention relates to an edit system with multimedia synchronous play and relative method, wherein it can be used in the teaching system with synchronous multimedia video and animation play function; it builds cue point in the play section and edits the play method of animation section, to make the animation elements to be played according to the cue point, to synchronously play video and animation.

Description

technical field [0001] The invention relates to an editing system and method for synchronous multimedia playback, in particular to an editing method applied to a teaching system with the function of synchronously playing multimedia video (Video) and animation (Animation). Background technique [0002] With the advancement of information technology and the advent of the era of network communication, the traditional teaching method is no longer the only way to transfer knowledge. The previous teaching products are generally limited to text, sound, or other rigid methods. Does not provide an environment for interaction with learners. However, by using multimedia programming, an interactive and relaxed teaching environment can be used to achieve the teaching effect. At present, the more common types of media include text (Text), sound (Audio), image (Image), animation (Animation) and video (Video), etc. At the same time, using a variety of media to spread information can expand...

[0003] However, there is a big difference between the multimedia application system and the traditional application system. The media used in the traditional application system is only "text", while the multimedia application system uses more types of media. For different multimedia materials, Because of their different characteristics, the processing methods are different. For example, the multimedia data display of text and video has nothing to do with time, but the multimedia data display of sound, animation, and video is related to time, and the processing methods are very different. , the amount of data processed is relatively large, so the system is more complicated

And a lot of media information needs to be displayed at the same time, so as to properly transmit the information, so it is necessary to do synchronous (synchronization) playback between media data. In the existing known multimedia teaching system, there is no method for editing the animation data and video data of the teaching multimedia that are played simultaneously, so that the designer of the multimedia teaching system must make animation data respectively according to the plot script of the teaching audio-visual data , and set the teaching system to play at the same time, but due to the different data characteristics and processing methods, when the system plays at the same time, it will often cause delays in data transmission, making video or animation data stop and lag, and cannot achieve complete Synchronous effect, and the formation of animation is a visual effect created by continuously displaying several pictures. If this method is used to make animations in accordance with the full duration of video playback, it is necessary to produce the number of animation frames for the full duration of video playback. , and edit the animation object for each animation frame (Frame), so it may often be necessary to modify and correct all the animation frames after this frame (Frame) because of the correction of a few animation frames, so editing The production process is also very expensive and inefficient
