Abstract: A computing device obtains a Network Abstraction Layer (NAL) unit header of a NAL unit of the multi-layer video data. The NAL unit header comprises a layer identifier syntax element having a value that specifies an identifier of a layer of the NAL unit. The layer identifier syntax element comprises a plurality of bits that represent the value within a defined range of values. A requirement of the bitstream conforming to a video coding standard is that the value of the layer identifier syntax element is less than the maximum value of the range of values.

Abstract: In one example, a video coder is configured to code a value for a syntax element indicating whether at least a portion of a picture order count (POC) value of a picture is to be reset to a value of zero, when the value for the syntax element indicates that the portion of the POC value is to be reset to the value of zero, reset at least the portion of the POC value such that the portion of the POC value is equal to zero, and code video data using the reset POC value. Coding video data using the reset POC value may include inter-predicting a block of a subsequent picture relative to the picture, where the block may include a motion parameter that identifies the picture using the reset POC value. The block may be coded using temporal inter-prediction or inter-layer prediction.

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 multiview video data, wherein the track includes one or more views, including only one of a texture view of a particular view and a depth view of the particular view. The method further includes parsing a track reference to determine a dependency of the track to a referenced track indicated in the track reference. Track reference types include ‘deps’ that indicates that the track includes the depth view of the particular view and the reference track includes the texture, ‘tref’ that indicates that the track depends on the texture view which is stored in the referenced track, and ‘dref’ that indicates that the track depends on the depth view which is stored in the referenced track.
