摘要：Portions (A1-D1) of multimedia program (presentation) are repetitivelybroadcast to receiving stations (122) with subsequent portions (C1-D1) being broadcast

less frequently than preceding portions (A1-C1). Blocks (a-f) of at least one of theportions (A1) are broadcast in varying permutations from one repetition to a nextrepetition. Further, each portion is of a length which is proportional to a sum of thelengths of all preceding portions. A receiver (122) is provided which selects blocks to beskipped (in a pyramid type broadcast) based on information indicative of the permutationselected by the server (100). The receiver (122) determines the number of blocks to skipbefore buffering the next block for the video being viewed.
