Retrying processing in access of data having different properties required such as reliability and real time property of the access is optimized. The coordinates of the input space are mapped by the processor to the coordinates of the output space by dividing the output space coordinates by the number of pixels in the output space per input space sample and adding a vector where k1 and k2 are equal to either 0 or minus 0. The product digital content is capable of being accessed and played back through a computer or game console at the customer site. The system is composed of three elements.
