    • Embodiments provide a method and apparatus for decoding/encoding a video signal using inter-layer prediction. The method includes obtaining inter-layer prediction identification information and quality identification information. The method further includes obtaining prediction constraint information based on the inter-layer prediction identification information and the quality identification information. The prediction constraint information indicates whether it is constrained to use an intra-base prediction mode in predicting a current block when a corresponding block covers at least two slices of a base layer. The method further includes decoding a current block by using the intra-base prediction mode when the prediction constraint information indicates it is not constrained to use the intra-base prediction mode in predicting the current block in case that the corresponding block covers at least two slices of the base layer.

    • In one embodiment, the method includes obtaining a reference picture list including multiple reference pictures, and determining an initial reference picture index of the multiple reference pictures in the reference picture list based on display order information for the multiple reference pictures. The reference picture index numbers increase for reference pictures having a decreasing display order with respect to a picture including the macroblock and the reference picture numbers increase for reference pictures having an increasing display order with respect to the picture including the macroblock. The reference picture index numbers of the reference pictures having a decreasing display order are less than the reference picture index numbers of the reference pictures having an increasing display order. The initial reference picture index is selectively modified to produce a determined reference picture index based on the macroblock level of the macroblock. The determined reference picture index is the initial reference picture index if the macroblock level of the macroblock is a frame, and the determined reference picture index is a modification of the initial reference picture index if the macroblock level of the macroblock is a field. The macroblock is decoded by selecting at least one reference picture from the reference picture list using the determined reference picture index.
    • 在一个实施例中,该方法包括获得包括多个参考图片的参考图片列表,并且基于多个参考图片的显示顺序信息确定参考图片列表中的多个参考图片的初始参考图片索引。 相对于包括宏块的图像,对于具有相对于包括宏块的图像的显示顺序减小的参考图像,对于具有相对于包括宏块的图像的显示顺序增加的参考图像,参考图像索引号增加。 具有减小的显示顺序的参考图像的参考图像索引号小于具有增加的显示顺序的参考图像的参考图像索引号。 选择性地修改初始参考图像索引以基于宏块的宏块级别产生确定的参考图像索引。 如果宏块的宏块级别是帧,则所确定的参考图片索引是初始参考图片索引,并且如果宏块的宏块级别是场,则所确定的参考图片索引是初始参考图片索引的修改。 通过使用确定的参考图片索引从参考图片列表中选择至少一个参考图片来解码宏块。
