    Abstract: Scalable coding concepts are described. One aspect improves parallel decoding of inter-dependent layers of a multi-layer video data stream by introducing a long-term syntax element structure for guaranteeing that during a predetermined time period the pictures of the dependent layer are subdivided so that borders of the spatial segments of the pictures of the second layer and the spatial segments of the first layer overlay. Another aspect concerns upsampling from base layer to enhancement layer. Another aspect introduces a long-term syntax element structure allowing the decoder to determine the inter-layer offset for a predetermined time period. Another aspect introduces a type indicator field changing a way a layer indicator field within the NAL unit headers is to be interpreted. Another aspect allows different codecs/standards to be used for the different layers. Another aspect concerns a syntax element structure which indicates the inter-layer offset in units of the base layer blocks.

    Abstract translation: 描述可扩展编码概念。 一个方面通过引入长期语法元素结构来改进多层视频数据流的相互依赖层的并行解码,以保证在预定时间段内从属层的图像被细分,使得空间段的边界 的第二层的图像和第一层覆盖物的空间段。 另一方面涉及从基层到增强层的上采样。 另一方面引入了长期语法元素结构,允许解码器在预定时间段内确定层间偏移。 另一方面引入了一种类型指示符字段来改变NAL单元头部中的层指示符字段将被解释的方式。 另一方面允许不同的编解码器/标准被用于不同的层。 另一方面涉及一种语法元素结构,其以基本层块为单位指示层间偏移。

    Abstract: The handling of scalable data streams by network entities is rendered less complex by, in the data stream, accompanying packets which actually carry data by packets of a different packet type which have a scalability axes descriptor defining the number of scalability axes and a semantic meaning thereof. In another aspect, the handling of scalable data streams by network entities is rendered more efficient by conveying level and/or profile descriptors using packets other than the data carrying packets, with profile and/or level descriptors being divided up into a first set explicitly signaling the definition of the available coding option set and/or available syntax element value range for a respective operation point, and a second set of profile and/or level descriptors which signal the definition of the available coding option set and/or available syntax element value range for their respective operation points by reference another profile and/or level descriptor.
