Abstract

A method of deriving parameters required for decoding a current layer of a coded multi-layer video sequence. The method comprises deriving a required parameter from one or more parameters associated with the current or a lower layer of the multiple layers. The invention makes use of an understanding that parameters which are required for decoding a current higher layer of a multi-layer video representation may be derived, i.e., inferred or predicted, from parameters associated with lower layers rather than explicitly signaled in a parameter set associated with the current layer. Also disclosed are a method of encoding parameters associated with such a current layer, corresponding computer program products, a corresponding parameter set decoder, and a corresponding parameter set encoder.
