摘要： An apparatus and a method for carrying out a fast discrete cosine transform (DCT) with same positions of input and output data, and also a recording medium which is readable by a computer with a program loaded thereon, are disclosed. In the intermediate arithmetic procedure of the one-dimensional or two-dimensional forward or inverse DCT, the positions of the input and output data are made same, and therefore, an additional memory is not required. Specifically, the apparatus for carrying out the fast discrete cosine transform (DCT) with same positions of input and output data includes an input data sequence transposing means for transposing a sequence of an externally inputted input data by using a transposing matrix E. A butterfly arithmetic means carries out a butterfly arithmetic operation by using a Gt−1Bt−1. Gt−2Bt−2 . . . G0B0 matrix on a data obtained as a result of transposing the sequence of the input data by the input data sequence transposing means. A repeated addition and regularization arithmetic means carries out a repeated addition and regularization arithmetic operation by using an FkQ0Q1 . . . Qt−1 matrix on a data obtained as a result of carrying out the butterfly arithmetic operation by the butterfly arithmetic means. The present invention is applicable to the conversion and inversion of digital signals.

摘要： A water ring encoding method of processing an initial data set, such as an image frame, is disclosed having a writing step and an encoding step. The initial data set is organized with at least one initial origin enveloped by a plurality of nested initial environs successively surrounding each other in the initial data set. The writing step includes writing a portion of data from the initial data set into a scanned data string, by starting the writing of the portion of the data from the initial data set into the scanned data string at the RC grouping corresponding to the initial origin (initial water ring (0)) and by sequentially progressing the writing outwardly from the family of RC groupings corresponding to the nearest nested initial environ (initial water ring (1)) towards the family of RC groupings corresponding to a furthest nested initial environ (initial water ring (n)). The encoding step includes encoding the scanned data string into an encoded data string.
