摘要： PROBLEM TO BE SOLVED: To provide an efficient distributed information source encoding method of data subjected to wavelet conversion.SOLUTION: The distributed information source encoding method includes, in descending order for each bit plane, a step for acquiring a list of important pixels (LSP), a step for acquiring a list of non-important pixels (LIP), a step for synchronizing the LSP, LIP and LIS of an information source image with those of a key image, a step for configuring a temporary list (TLIS) of a non-important set of the information source image, and a step for acquiring a syndrome corresponding to the size and positive/negative code of a pixel in the information source image by applying syndrome encoding to the LSP, LIP and TLIS of the information source image. These steps are executed in a processor.

摘要： PROBLEM TO BE SOLVED: To provide a system and method for determining a quasi-cyclic (QC) low density parity check (LDPC) code corresponding to a protograph and having a predetermined girth.SOLUTION: At least several elements of a connectivity matrix representing a protograph are duplicated along at least one line of duplication to produce an inflated connectivity matrix. Values of at least several elements in the connectivity matrix form a pattern indicated by a predetermined girth. A hierarchical quasi-cyclic (HQC) LDPC code corresponding to the inflated connectivity matrix is determined and at least several elements of a matrix representing the HQC LDPC code are removed, so that the matrix is squashed along the line of duplication to produce a QC LDPC code.
摘要翻译：要解决的问题：提供一种用于确定对应于原型并且具有预定周长的准循环（QC）低密度奇偶校验（LDPC）码的系统和方法。解决方案：表示原型图的连接矩阵的至少几个元素沿着至少一行重复复制，以产生充气连接矩阵。连通性矩阵中的至少几个元素的值形成由预定的长度指示的图案。确定对应于充气连通性矩阵的分层准循环（HQC）LDPC码，并且去除表示HQC LDPC码的矩阵的至少几个元素，使得矩阵沿着复制线被压缩以产生QC LDPC 码。版权所有（C）2013，JPO＆INPIT
