AHG8: Implementation of multi-layer decoding and output independent layer composition in VTM
Abstract
This contribution describes the software implementation in the VTM project realising the merging and the decoding of multiple independent layers into a single output decoded picture. The spatial relationship between these independent layers is described by expressing the top, right, bottom and left neighbour layer relative to each layer. This information is signalled in the bitstream (see JVET-R0307 for normative aspect of the signalling). The contribution further explains the different steps implemented in the VTM decoder to construct the final output decoded picture.
