| 摘要 |
The present invention discloses methods, devices and systems for effective and improved video data scalable coding and/or decoding based on Fine Grain Scalability (FGS) information. According to a first aspect of the present invention a method for encoding video data is provided, the method comprising obtaining said video data; generating a base layer picture based on said obtained video data, the base layer picture comprising at least one slice, said slice corresponding to a region within said base layer picture; and generating at least one enhancement layer picture corresponding to said base layer picture, wherein said at least one enhancement layer picture comprises at least one fine granularity scalability (FGS) slice, said at least one FGS-slice corresponding to a region within said enhancement layer picture, wherein the region to which said at least one of said FGS-slices corresponds is different from the region to which said slice in the base layer picture corresponds, encoding said base layer picture and said at least one enhancement layer picture resulting in encoded video data. |
