Embodiment Construction

[0033] This disclosure describes various techniques for coding 3D video content composed of texture views and depth views. The techniques may, in some aspects, be performed by a video encoder. In other aspects, the techniques may be performed by a video decoder. Base views may also be referred to herein as "reference layers" or "reference views." Additionally, views or layers other than the base layer may be referred to herein as "dependent layers" or "dependent views." In addition, the various techniques described herein may be performed by other devices, such as transcoders, media-aware network elements (MANEs), or other devices or units that process video data. In this disclosure, for purposes of illustration, the techniques are described with respect to video encoders and decoders.

[0034] Video decoding standards include ITU-TH.261, ISO / IEC MPEG-1 Visual, ITU-TH.262 or ISO / IEC MPEG-2 Visual, ITU-TH.263, ISO / IEC MPEG-4 Visual and ITU-TH.264 (also known as ISO / IEC MPEG...

Abstract

An example video coding device is configured to compare an inter-view predicted motion vector candidate (IPMVC) to a motion vector inheritance (MVI) candidate, where the IPMVC and the MVI candidate are each associated with a block of video data in a dependent depth view, and where the IPMVC is generated from a corresponding block of video data in a base depth view. The video coding device may be further configured to perform one of adding the IPMVC to a merge candidate list based on the IPMVC being different from the MVI candidate, or omitting the IPMVC from the merge candidate list based on the IPMVC being identical to the MVI candidate.
