Title
(EN) DECODER, TRANSMISSION DEMULTIPLEXER AND ENCODER
(ZH) 解码器、传送解多工器和编码器
Abstract
(EN) The invention relates to a decoder, a transmission demultiplexer and an encoder. A raw byte sequence payload describing a picture in slices, WPP substreams or tiles and coded using context-adaptive binary arithmetic coding is subdivided or chopped into tranches with continuing the context-adaptive binary arithmetic coding probability adaptation across tranche boundaries. By this measure, tranche boundaries additionally introduced within slices, WPP substreams or tiles do not lead to a reduction in the entropy coding efficiency of these elements. On the other hand, 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, i.e. slices, WPP substreams or tiles.
(ZH) 本申请涉及解码器、传送解多工器和编码器。一种以截割片、WPP子流或拼贴块描述一图像且使用上下文自适应二进制算术编码来编码的原始字节序列有效载荷经细分或切碎成份额,利用继续的该上下文自适应二进制算术编码概率适应性横跨份额边界。藉此措施,额外地导入截割片、WPP子流或拼贴块内部的份额边界不会导致此等元素的熵编码效率的减低。但相反地,份额小于原先截割片、WPP子流或拼贴块,且因此,份额可比未经切碎的原先实体亦即截割片、WPP子流或拼贴块更早传输,亦即具有更低的延迟。
