摘要： An image decoding method, apparatus and program for decoding coded picture data is disclosed. In the method, apparatus and program, the coded picture data is entropy-decoded to derive four transform coefficient strings each comprising entropy-decoded sixteen (16) transform coefficients. The four transform coefficient strings are combined into an 8x8 block of entropy-decoded sixty four (64) transform coefficients by de-interleaving the four strings in such a manner as to select a lower frequency transform coefficient alternately from the four strings and arrange it in the 8x8 block in an order of a low frequency to a high frequency. An inverse orthogonal transform is then performed on the 8x8 block of the entropy-decoded sixty four (64) transform coefficients.

摘要： An input image signal 101 is divided into MC block units and, when coding processing is performed in these divided units, a motion compensation section 107 generates a motion-compensated prediction image 106a by detecting movement amounts in predetermined MC block units, a smoothing filter section 124 performs, with respect to the prediction image 106a, smoothing of pixels located at the boundaries of adjoining MC blocks on the basis of predetermined evaluation criteria, and a prediction residual signal 108, which is obtained from the difference between the prediction image 106b obtained by the smoothing, and the input image (input image signal 101), is encoded. Accordingly, it is possible to use relatively straightforward computation to perform processing, with respect to a prediction frame image generated by block-unit motion-compensated interframe prediction (MC), to adaptively smooth a discontinuous waveform generated between MC blocks of the prediction frame image, whereby the efficiency of low bit rate coding that employs interframe MC is improved.
摘要翻译：输入图像信号101被划分成MC块单元，并且当在这些分割单元中执行编码处理时，运动补偿部分107通过检测预定MC块单元中的移动量来生成运动补偿预测图像106a，平滑滤波器部分根据预测图像106a，根据预定的评价准则，对位于相邻的MC块的边界的像素进行平滑处理，以及预测残差信号108，该预测残差信号108是从由平滑和输入图像（输入图像信号101）被编码。因此，对于由块单位运动补偿帧间预测（MC）产生的预测帧图像，可以使用相对简单的计算来对预测帧图像的MC块之间生成的不连续波形进行自适应平滑处理从而提高采用帧间MC的低比特率编码的效率。

摘要： A system for improving the transmission efficiency of channels involved in multilink communication and reducing the load of processing. A first data transmission apparatus changes the number of transmission channels involved in multilink communication from “x” to “y”, acquires SS (sampling size) and SPF(samples per frame) associated with the number of transmission channels “y” from an SS/SPF table, generates multilink frames based on the acquired SS and SPF, and transmits them to a second data transmission apparatus. When it is detected that the number of transmission channels has been changed from “x” to “y”, the second data transmission apparatus acquires the SS and SPF associated with the number of transmission channels “y” from the SS/SPF table, generates multilink frames based on the acquired SS and SPF, and transmits them to the first data transmission apparatus.
