Abstract
Various methods, apparatuses and computer program products for video encoding and decoding are provided. In some embodiments, to indicate a composition of pictures of different time instants, some usability information may be embedded to the video bitstream indicating the intended display behavior when more than one layer is used and associated display behavior using this information. More specifically, the embedded information may indicate how the layers need to be composed in the video bitstream. The information may indicate if the intended display behavior is to combine (overlay) base layer and enhancement layer decoded pictures. The information may indicate that the base and enhancement layer decoded pictures are allowed to be overlaid. In addition or alternatively, the information may indicate that the enhancement layer picture should not be combined with base layer picture during display.
