Claim 9:
10. The method according to claim 9, wherein when the region-inherited flag indicates none region of the respective frame to be depended on is inherited, the RWP coding configuration of the dependent frame comprises region parameters required to decoding the respective region of the dependent frame,
wherein one frame to be depended on has N regions, one dependent frame has M regions, and N and M are positive integers; and
in response to determining that an ith region of one of the frames to be depended on has at least one same region parameter as that of a jth region of the respective dependent frame,
the RWP coding configuration of the dependent frame comprises:
a region ID of the jth region of the frame to be depended on to indicate regions' dependency, and a parameter-inherited flag to indicated the at least one same region parameter of the ith region of the frame to be depended on is inherited;
wherein, the i is an integer, more than or equal to 0 and less than N, and the j is an integer, more than or equal to 0 and less than M,
or

wherein one frame to be depended on has N regions, one dependent frame has M regions, and N and M are positive integers; and
in response to determining that an ith region of one of the frames to be depended on has at least one same region parameter as that of an ith region of the respective dependent frame, the RWP coding configuration of the dependent frame indicates, by a parameter-inherited flag, which of the region parameters of the ith region of the frame to be depended on are inherited, wherein, the i is an integer, more than or equal to 0 and less than N, and less than M,
in response to determining that M is less than N, the RWP coding configuration of the dependent frame further comprises: a region-discarded flag, present in N-M regions parameters, which is configured to indicate discarding of a region, wherein the region is a region in the frame to be depended on, but not referenced by any region in the dependent frame; and
in response to determining that M is more than N, the RWP coding configuration of the dependent frame comprises region parameters required to decoding the last M-N regions of the respective dependent frame.
