    • A method for performing inter-layer prediction when encoding/decoding a video signal, includes confirming, by a decoding apparatus, whether or not only one macroblock of a field macroblock pair of a base layer is coded in intra mode, the field macroblock pair is two vertically adjacent field macroblocks. The method further includes predicting motion information of a current macroblock pair in an enhanced layer using motion information of an inter-mode macroblock in the field macroblock pair if the confirming confirms that only one of the macroblocks in the field macroblock pair is coded in the intra mode. A frame macroblock pair is constructed from the field macroblock pair if at least one of the macroblocks the field macroblock pair is coded in the intra mode, and texture prediction information of the current macroblock pair is obtained using texture information of the constructed frame macroblock pair.
    • 一种在对视频信号进行编码/解码时进行层间预测的方法,包括:由解码装置确认是否以帧内模式对基本层的场宏块对中的一个宏块进行编码,场宏块对为 两个垂直相邻的场宏块。 该方法还包括:如果确认确认在场宏块对中的仅一个宏块在帧内宏块对中进行编码,则使用场宏块对中的模式间宏块的运动信息来预测增强层中的当前宏块对的运动信息 模式。 如果场内宏块对中的至少一个宏块对以帧内模式编码,则从场宏块对构造帧宏块对,并且使用构造的帧宏块对的纹理信息获得当前宏块对的纹理预测信息。
