| The multi-view stereo video is a new video technology, with features of three-dimensionaland interoperability. It is a three-dimensional video by shooting multiple images of the same sc-ene from different perspectives. Compared to an ordinary two-dimensional video, stereo videoincrease the depth information of the scene, through three-dimensional display device, enablesthe viewer to get a stronger sense of reality and realism. Multi-view stereo video technologycontinues to evolve and data compression technology significantly improved, making the multi-view video with a very broad application prospects in some area,such as free viewpoint video,stereo TV, stereo, video conferencing, multi-view video-on-demand digitalentertainment. Three-dimensional combination of multi-view video is different from the2Dvideo, it is usually displayed after the decoding and the reconstruction, and by the raster displaythree-dimensional video effects, video decoder for playback after the combination of multi-viewalgorithm processing is more complexed.On the one hand multi-view video should be decodedand reconstruction, on the other hand should to achieve the audio and video synchronization,And the resolution is not high.In this paper, we propose off-line rendering multi-view stereo video to stereoscopic videodimensional treatment effect. However, the principle of multi-view stereo video raster displaymakes the combination of multi-view frame can not be encoded to the standard of ordinary two-dimensional video, must be loss-less compression. For multi-view stereo video, there will besome new requirements for audio and video synchronization.For the two-dimensional video, audio and video synchronization has many methods torealize, but it boils down to the main timestamp synchronization method, synchronized notation,and the multiplexer synchronization method, these synchronization methods mainly throughvideo and audio Markers playing side by marking achieve synchronization. Audio and videostreaming have some information on how fast and what time to play them on the inside, theaudio stream sampling, the video stream per second frame rate.This article by considering the multi-view stereo video raster display principle, the forma-tion of multi-view stereo frame by MPEG2compression, and multi-visual combination algorit-hm for offline rendering multi-view audio and video synchronization, two-dimensional video,audio and video synchronization method for multi-viewpoint combination of video lossless c-ompression, using the combination of multi-view video synchronization timestamp-based sy-nchronization method. |
