Claim 15:
16. The method according to claim 15, wherein the step of obtaining parameters of the dependent frame by decoding the RWP coding configuration of the dependent frame, based on the parameters of the respective independent frame corresponding to the dependent frame comprises:
obtaining parameters of the dependent frame by decoding RWP coding configuration of the dependent frame, based on the parameters of a previous frame, which is immediately before and has the dependency with each of a second type of dependent frames, and
the step of unpacking video frames, further comprises:
unpacking video frames, further based on the parameters of each of the second type of the dependent frames,
wherein the previous frame can be any one of the first type of the independent frames, the second type of the independent frames, the first type of the dependent frames, and the second type of the dependent frames;
wherein the method further comprises:
when a frame-type flag of the RWP coding configuration of the respective one of the dependent frames has a third value, determining which of the first type of the independent frames is depended, by matching a frame identity (ID) saved in the RWP coding configuration of the first type of independent frame stored, with a frame ID indicating frame that is depended on carried in the RWP coding configuration of the respective one of the dependent frames;
and/or
when a frame-type flag of the RWP coding configuration of the respective one of the dependent frames has a fourth value, determining that the immediately previous frame before the dependent frame is depended.
