Abstract

See full text

The invention relates to a method of encoding or decoding a scalable video sequence of frames encoded in a bit-stream made of at least one lower layer and one upper layer, the method comprising:

    decoding a lower layer bitstream to obtain first sample adaptive offset, SAO, parameters defining a first SAO filtering applied to at least one lower layer frame area; anddecoding an upper layer bitstream into at least one decoded upper layer frame area, using a second SAO filtering applied to at least one processed frame area of a processed frame based on respective second SAO parameters;wherein at least one flag in the bit-stream indicates that part or all of the second SAO parameters are inferred from the first SAO parameters
