<p>A scalable video coding method is provided. The scalable video coding method includes dividing an enhancement layer into macroblocks; when base_mode_flag or residual_prediction_flag of the macroblock is equal to 1, calculating a reference block coordinate value of a reference layer to refer to in the block up-sampling of the enhancement layer and up-sampling the macroblocks of the enhancement layer using the coordinate value; and coding the up-sampled macroblock. The execution speed of the scalable video codec can be raised and the memory usage required for the spatial inter-layer prediction of the scalable video can be saved.</p> |
