Abstract: A method and apparatus of scalable video coding using Inter prediction mode for a video coding system are disclosed, where video data being coded comprise BP (Basic Resolution Pass) pictures and UP (Upgrade Resolution Pass) pictures. In one embodiment according to the present invention, the method comprises receiving information associated with input data corresponding to a target block in a target UP picture. When the target block is Inter coded according to a current MV (motion vector) and uses a collocated BP picture as one reference picture, one or more BP MVs (motion vectors) of the collocated BP picture are scaled to generate one or more RCP (resolution change processing) MVs. The current MV of the target block is encoded or decoded using an UP MV predictor derived based on one or more temporal MVPs including said one or more RCP MVs.
