Abstract
Injection of 3D metadata into a requested video is disclosed. An input video and associated metadata are received by a video hosting site. If the metadata indicates that the input video is a 3D video, the 3D video system extracts the accompanying 3D metadata and stores it in an intermediate format, which is independent of the 3D metadata format and video format of the input video. The 3D video system stores the received video in a standard 2D video format in a video database. Responsive to a video streaming request of the input video, the 3D video system determines the actual 3D metadata format based on the video format of the requested video, and injects a modified 3D metadata associated with the input video into the requested video.
