Uçtan uca duraksız stereo video aktarım sistemi

Media streaming has been an active research area where efficient and network friendlymedia coding techniques, synchronization, bandwidth, packet loss and delay issues,delivery protocols, and, integrated media players and display systems have all beenaddressed since early 90?s. Today, there exist several open source and commercial productsthat can be used to build an integrated streaming environment supporting various audio andvideo formats. After the developments of streaming systems that feature classical, 2Dvideo, the attention now is focused on the third dimension; mostly because of the promisingprogresses in 3D displays and multi-view video coding techniques.Multi-view video contains views of the same scene from multiple perspectives capturedby several cameras. However, only two of these views can be watched by a human viewerat any given time. This brings the idea of developing streaming system delivering stereovideo that can be adapted to multi-view by selecting the two views displayed based on theuser?s current perspective. This thesis presents design and implementation of an end-to-endstereoscopic streaming system. The system has been constructed using the standardprotocols: Real Time Streaming Protocol (RTSP), Real-time Transport Protocol (RTP),Session Announcement Protocol (SAP) and Session Description Protocol (SDP) that arealso used in well known commercial and open source monoscopic streaming systems. Thesystem architecture is based on independent transmission of two channels of the stereovideo in order to achieve selective transmission of mono or stereo video depending on theavailable bandwidth or the user?s receiver and display equipment. The server side designedand developed to implement the basic functionalities required from an RTSP server. On thereceiver side, open source VideoLAN Client media player has been extended in order toprocess and display received stereo video sequences over two logical channels. Also, opensource Live555 RTSP library and FFMPEG codec library are integrated into the media1player for extending it to handle stereo streams. The resulting end-to-end platform consistsof a pre-encoded stereo-video-streaming server and a media player providing synchronizedstereo display on the client side with media delivery over RTP. The system is tested usingstereo video sequences compressed using H.264 Extension video codec and a displaywhere end users can view the stereo video using two projectors and polarized glasses.Attached File Names:Selen_Pehlivan_StereoVLC.zipSelen_Pehlivan_StereoRTSPServer.zip2
