| 摘要 |
The invention relates to scalable video coding of a video sequence made of at least one lower layer, generally a base layer, and one upper layer, generally an enhancement layer. A method of encoding or decoding such a scalable video sequence according to the invention comprises: 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; and decoding 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 part or all of the second SAO parameters are inferred from the first SAO parameters. |
