Abstract: In enhancement layer (EL) coding, the temporal candidate(s) may be derived the merge mode and the non-merge mode. Selection of the reference index of a current prediction unit (PU) and of the reference list of a co-located PU may be considered jointly when constructing the temporal candidate of EL for the merge mode.

A selected motion vector prediction candidate may be added to a merging candidate list in a position before that of a spatial motion vector prediction candidate. A selected motion vector prediction candidate may be added to the merging candidate list in place of a spatial motion vector prediction candidate.

Abstract: Visual information may be delivered to streaming-capable devices in a viewing environment, such as a home environment or a commercial environment. The visual information can be adapted to user behavior and/or viewing conditions in such a way as to deliver a satisfactory user experience while conserving network resources, such as bandwidth and/or capacity. Viewing distance and/or ambient light, which may affect viewing conditions in a viewing environment, may be estimated. Bandwidth may be reduced by eliminating details that may not be perceived by the user in the estimated viewing conditions (e.g., by determining a spatial resolution (e.g. a maximum spatial resolution) perceptible under the viewing conditions and not exceeding that spatial resolution).
