Abstract:
Parallel processing concepts such as wavefront parallel processing, are realized with a reduced end-to-end delay by giving up the usual slice concept according to which slices are either coded/decoded completely independent from areas of the picture outside of the respective slice, or at least independent from areas outside the respective slice as far as the entropy coding is concerned, namely in favor of slices of different modes, namely ones called dependent slices which allow for interdependencies across slice boundaries, and others which do not, called normal slices, for example. Combined with the aspect or not, WPP processing concept is made more efficiently by using the slices' start syntax portions to locate WPP entry points.

Claim (Index 12):
An encoder for encoding picture into a datastream, wherein the picture is partitioned into slices, the encoder comprising:\n a residual module configured to generate, using a processor, a residual signal related to a current slice of the slices of the picture; a predictor configured to generate, using the processor, prediction parameters based on a prediction signal, wherein the prediction parameters are encoded into the datastream; and an entropy encoder configured to determine, using the processor, a syntax element portion for the current slice and entropy encode, into the datastream, the slices based on wavefront parallel processing (WPP) in which the residual signal related to the current slice is entropy encoded according to one of at least two modes indicated by the syntax element portion, wherein the entropy encoder is configured to: if the current slice is to be coded in accordance with a first of the at least two modes, encode the residual signal using context adaptive entropy encoding comprising a derivation of contexts across slice boundaries and an initialization of the symbol probabilities depending on saved states of symbol probabilities of a previously encoded slice, if the current slice is to be coded in accordance with a second of the at least two modes, encode the residual signal using context adaptive entropy encoding with restricting the derivation of the contexts so as to not cross the slice boundaries and an initialization of the symbol probabilities independent on any previously encoded slice, and save symbol probabilities as acquired in context adaptive entropy encoding the previously encoded slice up to a certain coding block in a row in accordance with a raster scan order.
