Abstract

A first aspect provides concepts for handling coded layer video sequence boundaries in multilayered video bitstreams having inter-layer references. A second aspect provides concepts for handling, signaling and deriving of picture output timing, e.g. with respect to an access unit specific signaling and an output layer specific signaling of a number of repetitions of a picture output.
