Abstract: A video encoding and decoding system for use in a multiview and bitdepth coding system is described. Such system can comprise a plurality of layer groupings, where each group can be adapted to encode and/or decode based on predictions from previous layers and a plurality of data categories from the input video data.

Abstract: Context based inverse mapping methods are provided. An image with pixel values within a lower dynamic range can be mapped to an image with pixel values within a higher dynamic range by utilizing context information associated with pixels in the lower dynamic range image.

Abstract: Coding syntaxes in compliance with same or different VDR specifications may be signaled by upstream coding devices such as VDR encoders to downstream coding devices such as VDR decoders in a common vehicle in the form of RPU data units. VDR coding operations and operational parameters may be specified as sequence level, frame level, or partition level syntax elements in a coding syntax. Syntax elements in a coding syntax may be coded directly in one or more current RPU data units under a current RPU ID, predicted from other partitions/segments/ranges previously sent with the same current RPU ID, or predicted from other frame level or sequence level syntax elements previously sent with a previous RPU ID. A downstream device may perform decoding operations on multi-layered input image data based on received coding syntaxes to construct VDR images.

Abstract: An inter-layer reference picture is generated either by considering an inverse mapped signal from a base layer, a temporal signal from an enhancement layer, or a combination of both.
