PROBLEM TO BE SOLVED: To provide the multiplexing method which improves the transmission quality of data by maximally achieving error correction capability and has high efficiency, and to provide the data signal transmission method which improves the transmission quality by uniformizing the quality of data in a frame. SOLUTION: The multiplexing method codes input data for each input channel, multiplexes the coded data, performs an interleaving processing for randomizing rows to the multiplexed data, and outputs data. The data signal transmission method uses an interleaver whose number of columns is twice as many number of slots of frame, when performing the interleaving processing. COPYRIGHT: (C)2007,JPO&INPIT
