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.

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.
摘要翻译：公开了一种处理视频信号的方法。本发明包括获取当前宏块类型，根据当前宏块类型获得关于当前宏块的分区的跳过或直接模式指示信息，根据跳过或直接模式指示信息导出分区的运动矢量，并且预测使用运动矢量的分区的像素值。因此，本发明使用运动矢量来获得接近原始视频的参考块的像素值，从而提高宏块的重构率。由于宏块使用跳过或直接预测指示信息，因此不需要对宏块分别编码跳过模式指示信息和直接模式指示信息，从而可以减少要编码的信息大小。
