Embodiment Construction

[0039] In the method for transmitting video streams in the interactive multi-view video system proposed by the present invention, firstly, on the video server of the multi-view video system, the interactive position is set according to the number of actual viewpoints contained in each received multi-view video stream and interactive mode, establish and store the corresponding interactive video stream, establish the metadata of the multi-view video stream and store it in the configuration file of the corresponding multi-view video stream; the video server uses the session announcement protocol according to the above configuration file to send the multi-view The video session description information is sent to the client; the client uses the session initiation protocol to establish a session relationship with the video server according to the viewpoint parameters selected by the user; the client sends the viewpoint interaction request information to the above video server through ...

Abstract

This invention relates to a transmission method for video flows in an interactive multiple view points video system, which first of all sets up elemental data of the multiple view points video flow and stores them into a related file and sets up session relation between the customer end and a video server based on the file, a session inform protocol and a session start protocol. The customer end transmits the view point interaction request information to the video server by the session start protocol, the server utilizes the real time transmission protocol to send the video flow meeting the request of the customer end to the customer, which decodes the received video flow.

Description

technical field [0001] The invention relates to a video stream transmission method in an interactive multi-viewpoint video system, belonging to the technical field of information dissemination. Background technique [0002] Networking, interactivity and realism are the development direction of video technology. On the one hand, users hope to fully participate in video applications, and the relationship between humans and computers develops from passive to active, so as to fully realize the individual needs of each person; on the other hand, the real world is a three-dimensional environment, and traditional video mainly Based on the two-dimensional expression, although the three-dimensional information is expressed to some extent, the user requires a more realistic experience and feeling. Multi-viewpoint video is proposed for such interactive video applications, covering binocular stereoscopic video and multi-viewpoint video playback, and solving problems such as performance...
