Abstract:
A raw byte sequence payload describing a picture in slices, WPP substreams or tiles and coded using context-adaptive binary arithmetic coding is subdivided into tranches with continuing the context-adaptive binary arithmetic coding probability adaptation across tranche boundaries. Thereby, tranche boundaries additionally introduced within slices, WPP substreams or tiles do not lead to a reduction in the entropy coding efficiency of these entities. However, the tranches are smaller than the original slices, WPP substreams or tiles and accordingly they may be transmitted earlier, i.e. with lower delay, than the un-chopped original entities. According to another aspect combinable with the first aspect, substream marker NAL units are used within a sequence of NAL units of a video bitstream to enable a transport demultiplexer to assign data of slices within NAL units to the corresponding substreams or tiles so as to be able to, in parallel, serve a multi-threaded decoder with the corresponding substreams or tiles.

Claim (Index 1):
A non-transitory computer-readable medium for storing information related to an encoded picture of a video, comprising:\n a data stream stored in the non-transitory computer-readable medium, the data stream comprising encoded information related to a residual signal associated with a picture of a video, wherein the residual signal is determined based on a prediction signal, and is entropy-decoded using context adaptive binary arithmetic coding (CABAC) entropy decoding, wherein each row of the picture is encoded as one wavefront parallel processing (WPP) substream, wherein at least one WPP substream of the picture includes a plurality of tranches, wherein each tranche includes information indicating a boundary thereof within the at least one WPP substream, wherein the plurality of tranches are entropy-decoded using the CABAC entropy decoding with continuing CABAC probability adaptation from a first of the plurality of tranches within the at least one WPP substream across the boundary of the first tranche to a second of the plurality of tranches within the at least one WPP substream.
