VOD System

2D/3D VOD System

SIAT3DPlayer is a versatile player with the following three major functions: (1) Video recording. It supports the single-camera recording and dual camera recording, dual camera can record 3D video (left/right, up/down, etc.) or record seamless panoramic video. 4 kinds of video encryption methods are supported while recoding or transmission; (2) Video playback. The SIAT3DPlayer can play 2D/3D videos with various coding formats and 3D data formats. , and can automatically identify part of the 3D video format (left/right, up/down) and automatically set 3D playback effect. (3) Video-on-demand and live 3D broadcasting, SIAT3DPlayer is a video-on-demand client that supports the http protocol. It can play the videos on our website: http://codec.siat.ac.cn/vod/index.html and third party website. In addition, it supports live 3D broadcasting on RTP protocol.

Live VR Video System

SIATVRPlayer is a new developed video solution for VR video system, which is mainly comprised of 360° panorama picture producer, high efficiency video coder and VR video player. The 360° panorama picture is collaged from pictures of different view angles captured by a number of GoPro cameras. The VR video player is capable of displaying both the live 360°panorama video through RTMP and the available VR video online through URL. It provides three kinds of play mode: 1) VOD on HDTV. Pictures from monocular viewpoint is projected and displayed on 2D screen, one view or double view. The viewpoint can be changed arbitrary by moving the mouse and other input devices. 2) VOD on Head Mounted Device (HMD). Pictures from binocular viewpoint are generated and transferred to the HMD, so as to provide immersive experiences. The viewpoint can be seamless changed by turning head around without delay. 3) Live VR broadcasting.
