Abstract
A data distribution system that includes a distribution center apparatus for dividing digital content data into segments of multiple frequency bands, and converting the segments of digital content data into encoded data having compressed blocks, each block having a predetermined length unit and constituted by at least bit distribution information, normalized data and quantized data. The encoded data is transmitted so as to superimpose, if an empty portion exists in each of the blocks, a part or all of an identifier for identifying a provider of the digital content data onto the empty portion.
