Abstract: Disclosed herein are video coding techniques for prediction of a to-be-reconstructed block from enhancement layer/view data from base layer/view data in conjunction with enhancement layer/view data, where samples that are not available in the base or enhancement layer/view, respectively, are being predicted through padding.

Abstract: Disclosed are techniques for scalable, multiview, and multiple descriptive video coding using an improved Network Adaptation Layer (NAL) unit header. A NAL unit header can include a layer-id that can be a reference into a table of layer descriptions, which specify the properties of the layer. The improved NAL unit header can further include fields for reference picture management and to identify temporal layers.

Abstract: Disclosed are techniques for encoding and decoding layered video where the non-temporal enhancement layers and their respective temporal enhancement layers, comply with a scalable video coding standard or technology, and the base layer and its respective temporal enhancement layers does not comply with the same scalable video coding standard or technology. A Video Parameter Set that comprises information about the relationship of layers includes a syntax element indicative of the derivation mechanism for a temporal layer associated with a NAL unit coded in a first coding technology, for example HEVC. For one value of the syntax element, the derivation mechanism is to set the temporal layer of the base layer NAL unit to the value coded in the header of the encapsulating NAL unit, which can be an HEVC NAL unit. For another value, the derivation mechanism is to imply the value of temporal base layer for the first NAL unit.

Abstract: Techniques for video decoding include cross-layer prediction from a base layer to an SNR or spatial enhancement layer of spatial intra prediction mode information. In one example embodiment, the Most Probable Mode (MPM) for intra prediction of an enhancement layer block is predicted from the spatially corresponding base layer block.

Abstract: Techniques to determine a level id in a layered bitstream are disclosed, such that the same level id can be used for all layers of a scalable bitstream. Also disclosed are techniques to signal level ids for sub bitstreams that can be indicative of lower computational requirements than the level id used for the layered bitstream.

Abstract: A method for video decoding includes: decoding information including a description of a layer hierarchy including, for each layer, a layer_id, a reference_layer_id, and a dependent_flag; decoding for at least one access unit, a plurality of layer_not_present_flags, where each layer_not_present_flag is associated with at least one layer; and decoding Slice Network Abstraction Layer (NAL) units belonging to those layer(s) where the associated layer_not_present flag is not set.

Abstract: Disclosed are techniques for loop filtering in scalable video coding/decoding. An enhancement layer decoder decodes, per sample, coding unit, slice, or other appropriate syntax structure, an indication rlssp indicative of a stage in the base layer loop filter process. Reference sample information from a base layer for inter-layer prediction is taken from the indicated stage of the base layer loop filter.

Abstract: Techniques for video decoding include decoding a base layer of a first video coding technology and at least one enhancement layer conforming to a second video coding technology. The video coding technologies can be identified in a Dependency Parameter Set. Techniques for video encoding include encoding a base layer in a first video coding technology, at least one enhancement layer in a second video coding technology. Also disclosed are video communication systems using base and enhancement layer.

Abstract: The disclosed subject matter provides techniques for inter-layer prediction using difference mode or pixel mode. In difference mode, inter-layer prediction is used to predict at least one sample of an enhancement layer from at least one (upsampled) sample of a reconstructed base layer picture. In pixel mode, no reconstructed base layer samples are used for reconstruction of the enhancement layer sample, A flag that can be part of a coding unit header in the enhancement layer can be used to distinguish between pixel mode and difference mode.

The predictor list insertion module can generate a list of motion vector predictors, or modify an existing list of motion vector predictors, such that the list includes at least one predictor that is derived from side information generated by a base layer coding loop, and has been upscaled.
