    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: 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.

    摘要: A variable-length encoder that feeds a Coded Block Pattern (CBP) as an input symbol to variable-length code output part. Coded symbol memory supplies CBPs in neighboring blocks as coding map table reference information to coding map table provider. Coding map table provider determines a coding map table used in coding of the CBP, based on these CBPs in the neighboring blocks, and provides a coding map table H4 to variable-length code output part. Variable-length coding table provider feeds a variable-length coding table to variable-length code output part. Then the coding target CBP is subjected to variable-length coding, and the resultant is outputted as coded data. This allows information source coding of coding symbols to be performed efficiently according to the coding condition and the property of image.
