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 9):
The encoder according to  claim 7 , wherein the tranches are packetized using slice headers, and the entropy encoder is configured to, insert in a slice header of a new slice, a flag indicative of the new slice, a slice type of the new slice or a NAL unit type of a NAL unit comprising the new slice, such that a decoder is configured to, based on the flag, either interrupt the CABAC probability adaptation by resetting CABAC probabilities or to continue the CABAC probability adaptation.
