A method for providing and transmitting data in a data transmission system by transmitting several data blocks from a data-transmitting device to terminals. Before transmission of the data to the terminals an interleaving process of at least two data blocks is conducted. For the purpose of interleaving for each data unit of the data blocks, a transmission time is established with the help of an algorithm in such a way that for the transmission of k time critical data blocks with k=2, 3, 4, . . . and for one non-time critical data block, the transmission times of the data units of each time critical data block are respectively set at a fraction 1/k of the transmission time of the non-critical data block.
