Multi-view stereoscopic video with flat video compared to the huge amount of data on the storage, that transmission process produces a certain amount of difficulty , which has become a bottle neck in multi-view stereo video technology for industrial applications. And H.264 is the next generation video decode standard , it not only has a compression and transmission environment for a better adaptability , its application is very extensive than the scene . Thus based on the H.264 standard video codec technology has a very important practical value . While H.264 a compression efficiency standards in a very good performance , but rate on the test model decoder implementation is not very satisfactory, thus decoding speed and smooth playback of whether or not a significant influence. Firstly, the entropy decoding multi-view video of the CAVLC algorithm, parallel decoding algorithm decoding algorithm are studied . Then for decoding algorithms, optimization has algorithms for each are summarized . Keywords: multi-view video; decoder; parallel decoding; entropy decoding; optimization a
