Abstract

Video coding concepts are described which relate to encoding, decoding, extracting and mixing video data streams having encoded therein pictures in a manner subdivided into independently coded subpictures. The concepts relate to an extraction of subpicture specific video data streams having a layer of subdivided pictures and a layer of un-subdivided pictures, a handling of inter-layer prediction tools and a handling of scaling windows for inter-layer prediction for such video data streams, a determination of decoder capability requirements for such data streams, layer-specific constraints for such data streams, and mixing of subpictures encoded with different types of independent coding.
