Abstract

Signal quantities form a relief. The smaller the segments or blocks IK(n) of this INFORMATION SOLID IK are, the less become their (dynamic) ranges between their minimum and maximum. This forms range adaptively reduced code lengths CL for a range reduced PCM (RRPCM). Using hierarchically more and more narrow nestings of the space given by addresses and functional values, especially TRUE/FALSE-codes for CL-reduction/division, minimal CL(n) are obtained for a blockwise RRPCM. Depending on cumulations, composed RPCM-codes of variable lengths will result by exclusion. All IK(n) coded by RPCM, make IK reconstructable without informations about extremes (!), utilizing overlappings or differences at the border, especially along CORRELATION LINES. Overhead reduction: 81 % ! The possible punctual exactness allows range reduced application of other methods. Activity dependent, exactness becomes reducible within components step by step, enabling (non-) linear interpolations. In static areas the temporal mean value is codable.
