摘要： Disclosed is technology associated with video encoding and decoding having a structure including one or more layers (quality, spatial, and view) and technology associated with a method that predicts an higher layer signal by using one or more reference layers in encoding and decoding an higher layer. In more detail, an interlayer prediction is capable of being performed by considering a characteristic of each layer by separating a spatial and quality reference layer list constituted by spatial and quality layers to be referred at the same view as a target layer and a view reference layer list constituted by the same spatial and quality layers as a target layer in encoding and decoding encoding and decoding pictures of an higher layer in encoding and decoding encoded and decoded pictures of the higher layer to improve encoding and decoding efficiency.

摘要： The present invention is related to a method for moving the position of a base view from an arbitrary GOP (Group Of Pictures) start position to implement an efficient encoding structure in multi-view video encoding. The existing multi-view video encoding method exhibits low encoding efficiency when correlation between the base view and a dependent view is low, since the base view is assumed to be fixed. Moreover, in case the view in a live broadcasting program desired by a producer changes from the base view to another, the user has to consume more bit streams and decoder complexity than those consumed when decoding is performed with respect to the base view. Therefore, to alleviate the drawbacks of the existing multi-view video encoding method, the present invention provides a method for designing syntax elements by which the base view can be moved, thereby supporting an efficient encoding structure.

摘要翻译： 本发明涉及一种用于从任意GOP（图像组）开始位置移动基本视图的位置的方法，以在多视点视频编码中实现有效的编码结构。 现有的多视点视频编码方法在基视图和从属视图之间的相关性较低时表现出较低的编码效率，因为假设基本视图是固定的。 此外，在生产者期望的实况广播节目中的视图从基本视图改变到另一个的情况下，用户必须比相对于基本视图执行解码时消耗更多的比特流和解码器复杂度。 因此，为了减轻现有的多视点视频编码方法的缺点，本发明提供了一种用于设计可以移动基本视图的语法元素的方法，从而支持有效的编码结构。
