Abstract: In one embodiment, the method includes determining, by a moving picture coding system, motion vectors of the bi-predictive image block based on a type of the first reference picture. The type is one of a long-term type and a short-term type, and characterizes a temporal distance of the first reference picture with respect to the bi-predictive block. The motion vectors of the bi-predictive image block are determined according to a first set of expressions if the first reference picture is of the short-term type, and according to a second set of expressions if the first reference picture is of the long-term type. The second set of expressions is different than the first set of expressions. The method further includes decoding the bi-predictive image block by using the first reference picture and the second reference picture based on the determined motion vectors.

Abstract: A method and an apparatus of decoding a video signal are provided. The present invention includes the steps of parsing first coding information indicating whether a residual data of an image block in the enhanced layer is predicted from a corresponding block in the base layer, from the bitstream of the enhanced layer, and decoding the video signal based on the first coding information. And, the step of parsing includes the step of performing modeling of the first coding information based on second coding information indicating whether prediction information of the corresponding block in the base layer is used to decode the image block in the enhanced layer. Accordingly, the present invention raises efficiency of video signal processing by enabling a decoder to derive information on a prediction mode of a current block in a decoder instead of transferring the information to the decoder.
