    Abstract: This disclosure describes techniques for signaling and processing information indicating simplified depth coding (SDC) for depth intra-prediction and depth inter-prediction modes in a 3D video coding process, such as a process defined by the 3D-HEVC extension to HEVC. In some examples, the disclosure describes techniques for unifying the signaling of SDC for depth intra-prediction and depth inter-prediction modes in 3D video coding. The signaling of SDC can be unified so that a video encoder or video decoder uses the same syntax element for signaling SDC for both the depth intra-prediction mode and the depth inter-prediction mode. Also, in some examples, a video coder may and/or process a residual value generated in the SDC mode using the same syntax structure, or same type of syntax structure, for both the depth intra-prediction mode and depth inter-prediction mode.

    Abstract: In an example, a process for coding video data includes determining a partitioning pattern for a block of depth values comprising assigning one or more samples of the block to a first partition and assigning one or more other samples of the block to a second partition. The process also includes determining a predicted value for at least one of the first partition and the second partition based on the determined partition pattern. The process also includes coding the at least one of the first partition and the second partition based on the predicted value.

    Abstract: An asymmetric frame of a coded video bitstream may include a full resolution picture of a left view and a reduced resolution picture of a right view, where the left and right views form a stereo view pair for three-dimensional video playback. In one example, an apparatus includes a video encoder configured to receive a first picture of a first view of a scene having a first resolution, receive a second picture of a second view of the scene having a reduced resolution relative to the first resolution, form an asymmetric frame including the first picture and the second picture, and encode the asymmetric frame. In this manner, decoders of varying capabilities may receive the same bitstream, and the bitstream may consume less bandwidth than one or more bitstreams having full resolution pictures of a stereo view pair. The bitstream may have better quality than a bitstream having subsampled pictures.

    Abstract: Fast restoration of referential integrity between metadata and data after they were restored to some inconsistent backup copies in content management archival solutions. An inferred logging mechanism uses separate metadata and data logs to capture recent update activities during normal system conditions with additional object reference information using a method called reference tagging. This requires no system internal changes and introduces no performance overhead. The information in the logs facilitates quick identification of potential referential inconsistencies and allows referential integrity between metadata and data to be restored in a fraction of the time when compared to exhaustive data scans.
