Abstract: Techniques for encapsulating video streams containing multiple coded views in a media file are described herein. In one example, a method includes parsing a track of video data, wherein the track includes one or more views. The method further includes parsing information to determine whether a texture view or a depth view of a reference view is required for decoding at least one of the one or more views in the track. Another example method includes composing a track of video data, wherein the track includes one or more views and composing information that indicates whether a texture view or a depth view of a reference view is required for decoding at least one of the one or more views in the track.

Abstract: A video encoder generates a network abstraction layer (NAL) unit that includes at least a first syntax element and a second syntax element. The first syntax element indicates that the NAL unit belongs to a particular NAL unit type. Coded slices of texture view components and depth view components are encapsulated within NAL units that belong to the particular NAL unit type. The second syntax element indicates whether a NAL unit header of the NAL unit includes an Advanced Video Coding (AVC)-compatible 3-dimensional video (3DV) header extension or includes a Multiview Video Coding (MVC)-compatible 3DV header extension. The video encoder outputs a bitstream that includes the NAL unit. A video decoder receives the NAL unit and determines whether the second syntax element indicates that the NAL unit header of the NAL unit includes the AVC-compatible 3DV header extension or the MVC-compatible 3DV header extension.
