ABSTRACT:
In a data delivery server apparatus to which a plurality of terminal equipments each having a unique identifier are connected, a storage section stores a plurality of data, each of which includes one or more data blocks. A quantizing section receives an access request as pre-quantization access request from each of the plurality of terminal equipment. The pre-quantization access request requests a data stored in the storage section. The quantizing section also quantizes the access request to produce one or more post-quantization access requests associated with one or more data block of the data. A reducing section produces a collective access request from the post-quantization access requests belonging to each of quantization regions of the quantizing section. An access section accesses the storage section in accordance with each of the collective access requests to read out the corresponding data block from the storage section. A delivery section for delivering the data block to the terminal equipments which have issued the pre-quantization access requests corresponding to each of the collective access request.
