    • The present invention relates to a method that uses a motion vector of a predictive video frame of a sub-layer to encode a video signal and decode encoded video data. The method encodes a video signal using a preset method to a bit stream of a base layer while encoding the video signal using a scalable MCTF method to a bit stream of an enhanced layer. When an arbitrary frame of the video signal is encoded, information, enabling at least one vector, derived from a first motion vector of a first block included in the bit stream of the base layer in the same direction as the first motion vector, to be used as a motion vector of an image block in the arbitrary frame, is recorded in the bit stream of the enhanced layer. The first motion vector is directed in the same direction as a temporal direction from the arbitrary frame to the first block.
    • 本发明涉及使用子层的预测视频帧的运动矢量对视频信号进行编码并解码编码的视频数据的方法。 该方法使用预设方法将视频信号编码到基本层的比特流,同时使用可缩放的MCTF方法将视频信号编码到增强层的比特流。 当对视频信号的任意帧进行编码时,能够使包含在与第一运动矢量相同方向的基本层的比特流中的第一块的第一运动矢量中的至少一个矢量的信息成为 用作任意帧中的图像块的运动矢量被记录在增强层的比特流中。 第一运动矢量指向与从任意帧到第一块的时间方向相同的方向。

    • In one embodiment, the method includes determining reference picture index numbers in a reference picture list. The reference picture index numbers increase for reference pictures having a decreasing display order with respect to a picture including the macroblock. The reference picture numbers increase for reference pictures having an increasing display order with respect to the picture including the macroblock, and the reference picture index numbers of the reference pictures have a decreasing display order are greater than the reference picture index numbers of the reference pictures having an increasing display order. Motion vector information is obtained for the current field macroblock. A field reference picture index associated with the current field macroblock is obtained. A frame reference picture is selected based on the frame reference picture index and the reference picture index number. A field reference picture is selected having a parity different from a parity of the field macroblock if the field reference picture index is an odd value, and the current field macroblock is decoded based on the motion vector information and the selected field reference picture.
    • 在一个实施例中,该方法包括确定参考图片列表中的参考图片索引号码。 相对于包括宏块的图像,具有降低的显示顺序的参考图像的参考图像索引号增加。 相对于包括宏块的图像具有增加的显示顺序的参考图像的参考图像编号增加,并且参考图像的参考图像索引号具有减小的显示顺序大于具有 越来越多的显示顺序。 获得当前场宏块的运动矢量信息。 获得与当前场宏块相关联的场参考图像索引。 基于帧参考图像索引和参考图像索引号来选择帧参考图像。 如果场参考图像索引是奇数值,则选择具有与场宏块的奇偶校验不同的奇偶校验的场参考图像,并且基于运动矢量信息和所选择的场参考图像对当前场宏块进行解码。
