Patent ID: 8630352

Claim:
A scalable video encoding method, comprising: (a) determining whether a block of a base layer, which corresponds to a block of an enhancement layer of a current frame to be encoded, is in a skip mode only by determining whether block data of the base layer is the same as block data of a reference frame base layer in the temporal direction; (b) overriding a previous weight value that has been set for a block of an enhancement layer of a reference frame with a new weight value, the block of the enhancement layer of the reference frame corresponding to the block of the enhancement layer of the current frame, whenever block data of the base layer is the same as the block data of the reference frame base layer in the temporal direction; and (c) generating a reference block for the block of the enhancement layer of the current frame based on the block of the enhancement layer of the reference frame and the block of the base layer of the current frame using the new weight value.
