| Due to the advantages of stereoscopic video in ornamental and visual authenticity, stereo video technology has become a hot topic in the field of information science and technology today. JVC (Joint Video Coding) even set up a special research group to study stereoscopic video and even Multi-view Video Coding (MVC). Although the stereoscopic video owns many advantages, but the increase of codec complexity, the transmission bandwidth consumed as well as other new problems caused by the unique characteristics of the stereo video are all very worthy of analysis and research. This article is very for stereoscopic video codec problem and its streaming transmission issues to analyze and research.Firstly, stereoscopic video codec technology is introduced briefly from forming theory, videos getting to terminal show. Then, this paper introduced the stereo video coding, which is extended to Multi-view Video Coding (MVC). This paper creatively provided a Multi-view Video Codec algorithm under a low-bit-rate environment. Tests have proved this algorithm can save about14%bit-rate with a cost of0.2dB loss. Moreover, this paper also proposed one kind of Sony’s Blu-ray stereoscopic video stream decoding scheme, and successfully achieved it. The codec can decode at a speed of2.364frames per second for both left and right video stream.Secondly, this paper discussed and analyzed the streaming technology for stereoscopic video from basic transport protocol, transmission and transfer process to the unique characteristics and needs of the stereoscopic video streaming. This paper designs a set of stereo video streaming plan, and verified that the pan is feasible through follow-up chapter. It also explores the scalability and compatibility issues of the system design plan.Then Synchronization is analyzed and discussed. It is a pivotal issue in the stereoscopic video streaming technology. Synchronization issues explored here can be divided into two sides, synchronization of the network transmission and the terminal display. On the basis of traditional video and audio stream network transmission synchronization method, this paper realized a stereo video streaming transmission synchronization scheme, and a terminal synchronization display scheme based on the multi-thread synchronization method. These schemes are achieved to prove its feasibility through a follow-up chapter of system realization.Finally, this paper realized a stereoscopic video streaming system. The system is built on the basis of the Video Lan Client and Live555open source projects. The system design and the concrete realization prove that the solutions of several key issues described in the preceding chapters are feasible. Then, this chapter describes the system running and testing results. The test results show that it has up to82.5%rate for accuracy synchronization, and the other17.5%is for basic synchronization. |
