    摘要: Disclosed is a method for scalably encoding and decoding a video signal. The video signal is encoded through an inter-layer prediction scheme based on a data stream of a base layer encoded with ×¼ resolution. The inter-layer prediction scheme applied between the enhanced layer and the base layer representing ×4 resolution difference includes a motion prediction scheme for predicting motion and dividing a macro block of the enhanced layer based on division information, mode information, and/or mode information of a block of the base layer. Thus, the inter-layer prediction scheme is applied between layers representing ×4 resolution difference, thereby improving a coding efficiency.

    摘要: Disclosed is a method for encoding a decoding a video signal. In the procedure of encoding the video signal, when a frame temporarily simultaneous with a frame including a macro block of an enhanced layer which will obtain a prediction video does not exist in a base layer, the macro block is encoded based on difference values of residual data using corresponding residual blocks in a past frame and a future frame of the base layer which are residual data corresponding to image difference values and using a residual block for the macro block of the enhanced layer. In another embodiment, the macro block is encoded based on difference values of residual data using corresponding residual blocks in a past frame and a future frame of the enhanced layer and the residual block for the macro block. Accordingly, a residual prediction mode is applied for a macro block of an enhanced layer even if a frame temporally simultaneous with a frame of the enhanced layer does not exist in a base layer, thereby improve coding efficiency.

    摘要: The method includes receiving a multi-view video stream including a random access picture, which includes a random access slice. The random access slice references only a slice corresponding to a same time and a different view of the random access picture. Type information indicating whether the random access slice is predicted from one or two reference pictures is obtained, and a reference picture list is initialized using view number information and view identification information included in obtained initialization information according to the type information. The initialization information is obtained based on a value indicating decoding order between the plurality of views. The initialized reference picture list is modified based on modification information representing how to assign an inter-view reference index in the initialized reference picture list. A prediction value of a macroblock in the random access picture is determined based on the modified reference picture list, and the macroblock is decoded using the prediction value.

Accordingly, the present invention is able to raise coding efficiency of video signal by adding an intra prediction mode as a sub-macroblock in predicting a macroblock.

    摘要: A method of processing a video signal is disclosed. The present invention includes obtaining a current macroblock type, obtaining skip or direct mode indication information on a partition of the current macroblock according to the current macroblock type, deriving a motion vector of the partition according to the skip or direct mode indication information, and predicting a pixel value of the partition using the motion vector. Accordingly, the present invention obtains a pixel value of a reference block close to an original video using a motion vector, thereby enhancing a reconstruction ratio of the macroblock. As a macroblock uses skip or direct prediction indication information, it is unnecessary to separately code skip mode indication information and direct mode indication information on the macroblock, whereby an information size to be coded can be reduced.
