Abstract: Techniques are described for signaling of representation format information in multi-layer bitstreams. Representation format information is signaled using representation format syntax structures included in a video parameter set (VPS) for a video sequence in a multi-layer bitstream. When syntax elements associated with the representation format syntax structures are not present in the VPS, a mapping of representation formats to layers in the multi-layer bitstream may be inferred. According to the techniques, in the absence of the syntax elements, a video decoder infers which of the representation format syntax structures is applied to which of the layers in the bitstream based on a number of the representation format syntax structures included in the VPS for the video sequence. By basing the inference on the number of representation format syntax structures for the video sequence, the inference may be accurate for the type of multi-layer video extension used in the multi-layer bitstream.

Abstract: A video encoder may generate a bitstream that includes a syntax element that indicates whether inter-layer prediction is enabled for decoding a tile of a picture of the video data. Similarly, a video decoder may obtain, from a bitstream, a syntax element that indicates whether inter-layer prediction is enabled. The video decoder may determine, based on the syntax element, whether inter-layer prediction is enabled for decoding a tile of a picture of the video data, and decode the tile based on the determination.
