摘要:
为了更好地解决多视点立体视频数据的音视频同步问题，提出了一种基于Direct Show的多视点立体音视频信号压缩编解码同步方案。根据多视点立体视频的光栅显示特点，充分利用了立体视频帧内以及帧问的冗余相关性实现了立体视频数据的无损压缩，同时针对音频数据采用了基于子带编码的方式进行压缩，最后将多视点立体视频与音频数据通过压缩编码后写入立体视频文件，并在解码端通过同步控制机制实现了音视频的同步。实验结果表明，此方法能有效地实现多视点立体音视频同步
Abstract:
In order to effectively solve the audio and video synchronization problems of the multi-view video data, a solution based on DirectShow for the synchronized decode and compression of the stereoscopic audio and video is proposed. According to the feature of the multi-view display, three-dimensional video data adopts the lossless compression algorithms, make full use of the redundant correlation of the stereo frame and between the frames to implement compression, and the audio data is encoded with the lossy compression based on the sub-band coding mode. Then the multi-view video and audio data are encoded and stored into the specific video file which supports the synchronized decode through the synchronous control mechanism. The synclaronization effect is verified by the experiment
