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 4):
The computer-readable medium according to  claim 1 , wherein the tranches are packetized into packets in the data stream in a manner so that each packet comprises one tranche of each WPP substream of the picture, or a subset of the WPP substreams of the picture, arranged in an order defined among the WPP sub streams, each packet comprising a header comprising information revealing positions and/or lengths of the tranches packed into the respective packet, or markers separating the tranches within the respective packet from each other, wherein the information comprised by the headers or the markers is used to access the tranches within the packets.
