<p>A method of multi-layer based scalable video encoding and decoding and an apparatus for the same are disclosed. The encoding method includes the steps of estimating motion between a base layer frame that is placed at a temporal location closest to a current frame of an enhancement layer, and a frame that is backwardly adjacent to the base layer frame to acquire a motion vector, generating a residual image by subtracting the backwardly adjacent frame from the base layer frame, generating a virtual forward reference frame using the motion vector, the residual image and the base layer frame, and generating a predicted frame with respect to the current frame using the virtual forward reference frame, and encoding the difference between the current frame and the predicted frame.</p> |
