Abstract
A video decoding method for decoding a bit stream to a plurality of frames, includes: determining whether a size of a current picture is equal to that of a next picture according to the bit stream; scaling a corresponding reference frame for the next picture to generate a scaled frame when the size of the current picture is not equal to that of the next picture; and storing the scaled frame in a first frame buffer of a storage unit, wherein at least a portion of a first frame originally stored in the first frame buffer is displayed.
