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.

Claim (Index 9):
A video encoder for encoding a scene into a multi-layer video data stream in a hierarchy of layers so that the multi-layer video data stream is decodable in accordance with spatial segments derived by sub-dividing pictures of the layers, the video encoder comprising:\n a predictor configured for generating, with respect to each of the spatial segments of a picture of a first or second layer of the layers, a prediction signal based on a coding parameter; a residual determiner configured for determining residual data associated with the spatial segment of the picture; and an entropy encoder configured for entropy encoding the coding parameter and the residual data into the multi-layer video data stream, wherein the video encoder is configured for signaling subdivision of pictures of the first and second layers by inserting a long-term syntax element and a short-term syntax element into the multi-layer video data stream, the short-term syntax element defining the subdivision of the pictures of the first layer and the second layer into their respective spatial segments, which includes a first value indicating that the spatial segments of a picture of the second layer do not spatially align with the spatial segments of a picture of the first layer, and a second value indicating that at least one of the spatial segments of the picture of the second layer spatially aligns with a corresponding one of the spatial segments of the picture of the first layer, and wherein the long-term syntax element having a first value indicates that a picture of the second layer is subdivided in a manner that at least one of the spatial segments of the picture of the second layer is spatially aligned with a corresponding one of the spatial segments of the picture of the first layer.
