摘要

There is provided a contents distribution method in which burdens imposed on a distribution service provider and a contents user are lightened so that the contents user can use contents as many as possible at low cost. A system comprises terminal apparatuses 1, a portal server 3, a contents DB 4, a contents distribution server 5, a cabinet management server 6, and an accounting server 7. The cabinet management server 6 manages the contents usable limit and contents storage status of each of the terminal apparatuses 1. The portal server 3 and the cabinet management server 6 cooperate with each other to generate the contents usable limit for each terminal apparatus 1 and instruct the contents distribution server 5 to distribute contents in accordance with a contents distribution request given from the terminal apparatus 1. To distribute the contents, the remaining capacity of the contents usable limit in the terminal apparatus 1 is obtained based on information concerned with available contents and deleted contents in the terminal apparatus 1 so that an instruction is given to distribute the contents within the remaining capacity.
