摘要： The present invention relates to an image signal coding apparatus and method, an image signal transmission method and a recording medium in which an input image signal is divided into a plurality of blocks and a reference image signal is used for carrying out a motion compensative prediction coding to each of the blocks. The present invention is characterized in that a reference image signal is used for each of the blocks to calculate: a motion vector prediction residue of a block for which a motion compensation is carried out; a residue of a block for which no motion compensation is carried out; and an average luminance value of pixel data within a block and a flatness value of the block. For each of the blocks, a magnitude of the aforementioned block motion vector prediction residue is compared to a magnitude of said block residue so that a result of this comparison is used to decide whether to carry out a motion compensation coding. In this process, the average luminance value and the flatness value of the block are used to switch between decision making region division types. According to a result of this decision, a motion compensative prediction coding is carried out for each of the blocks. Thus, even when a prediction residue is small on a flat portion of a image, it is possible to prevent generation of a fixed noise and improve the coding efficiency without deteriorating the image quality.
摘要翻译： 图像信号编码装置及方法，图像信号发送方法以及记录介质技术领域本发明涉及图像信号编码装置和方法，图像信号发送方法以及记录介质，其中输入图像信号被分成多个块，参考图像信号用于执行运动补偿预测编码 到每个块。 本发明的特征在于，对每个块使用参考图像信号来计算：执行运动补偿的块的运动矢量预测残差; 不执行运动补偿的块的残差; 以及块内的像素数据的平均亮度值和块的平坦度值。 对于每个块，将上述块运动矢量预测残差的大小与所述块残差的幅度进行比较，以使得该比较的结果用于决定是否执行运动补偿编码。 在该处理中，块的平均亮度值和平坦度值用于在决策区域划分类型之间切换。 根据该决定的结果，针对每个块执行运动补偿预测编码。 因此，即使在图像的平坦部分上的预测残差较小的情况下，也可以防止产生固定噪声，提高编码效率，而不会降低图像质量。

摘要： Contents data that have been enciphered and transmitted are recorded as they are on a recording medium, and the contents key used to encipher these data is enciphered in a way used in this recording system and is recorded on the medium. Moreover, a step is taken to ensure that fine trick plays can be performed. In recording contents data that have been enciphered and transmitted, the contents data themselves are recorded in the enciphered state on the recording medium. However, the contents data are decoded by a contents data decoding circuit 46, and a map file containing necessary management information for reproduction is created by a map file creating circuit 47 and this file is recorded together with the contents data.
