Claim 17:
18. The method according to claim 17, wherein the step of obtaining the region parameters of the inherited region, based on the RWP coding configuration of the dependent frame and the RWP coding configuration of the respective frame that is depended on, comprises:
when a parameter-inherited flag in the RWP coding configuration of the dependent frame indicates at least one region parameter corresponding to the parameter-inherited flag, of the frame that is depended on is inherited, obtaining the inherited region parameters from the RWP coding configuration of the frame that is depended on,
and/or
when a parameter-inherited flag in the RWP coding configuration of the dependent frame indicates none region parameter corresponding to the parameter-inherited flag, of the frame that is depended on is inherited, obtaining the inherited region parameters from the RWP coding configuration of the dependent frame,
wherein before the step of the obtaining the region parameters, the method further comprises:
determining which region in the frame that is depended on is inherited, according to a region ID indicating regions' dependency, in the RWP coding configuration of the dependent frame;
or
in response to there being no region ID indicating regions' dependency, determining an mth region in the frame that is depended on is inherited, when the region-inherited flag of an mth region in the dependent frame indicates having regions' dependency, wherein m is zero or a positive integer, and m is less than or equal to M-1, M being a smaller of a total number of regions in the dependent frame and a total number of regions in the frame that is depended on.
