Abstract
The achievement of broadband information transmission media, makes it possible to perform on-demand information distribution. With this comes a desire for an autonomous information distribution system that meets both diverse client requirements and the need for a high level of immediacy.An objective of the present invention is to provide such information distribution systems. The systems of the present invention comprise a means for managing the number of distributions, a means for generating an advertising list in which the extraction probability of each information material in the case of random extraction is the ratio of the remaining number of distributions of each information material to the overall remaining number of distributions, a means for handicap application which applies a handicap to the remaining number of distributions of each information material included in the advertising list, and a means for random extraction which performs random extraction with respect to the advertising list so as to extract one information material. In these systems of the present invention, extracted information materials are distributed to a distribution demand terminal from the informat…
