Abstract: A protocol termination device includes: a transfer unit configured to transfer distribution data transmitted from a distribution device to a request device that has requested the distribution data, and a suppression control unit configured to perform suppression control for monitoring a transmission amount per unit time of the distribution data being transmitted from a transmission buffer of the protocol termination device to the request device in the transfer processing and requesting transmission of the distribution data having a data amount that is equivalent to the transmission amount per unit time, from the distribution device.

Abstract: A cash management device includes: a latest access list acquisition unit that acquires a latest access list showing a history of a Web content accessed within a predetermined period of past for which present is set as a reference; and a deletion target determination unit that determines a deletion target Web content, the deletion target Web content being a Web content that should be deleted from a high-frequency access list when a Web content is added to the high-frequency access list based on the latest access list, the high-frequency access list showing a Web content that a distribution server device should accumulate as cash data. The deletion target determination unit specifies a Web content whose access frequency is lower than a lower limit reference for each of a plurality of different periods, and selects the deletion target Web content from the specified Web content.

Abstract: A content distribution device includes: a content acquisition unit that acquires a content to be accessed based on a access request transmitted from an access request source, the content to be accessed being indicated by the access request; an encoding unit that encodes the acquired content; a content distribution unit that distributes the encoded content to the access request source; and a content transfer unit that transfers the encoded content to a high-speed distribution device in a case where access frequency to the encoded content is higher than a threshold, the high-speed distribution device exclusively distributing a content and being independent of the content distribution device.

Abstract: A moving-picture processing device distributing moving-picture data to an information processing terminal includes: a division processing unit for generating a plurality of divided moving-picture data obtained by dividing moving-picture data, a moving-picture processing unit for subjecting each data item of said plurality of divided moving-picture data to a distribution process for distributing moving-picture data, and a distribution processing unit for sequentially distributing, by each arbitrary data amount as distribution data to the information processing terminal, each data item of said plurality of divided moving-picture data that have undergone the distribution process. The moving-picture processing unit executes the distribution process in parallel.

Abstract: Provided is a contents distribution system including: a unit for dividing contents data stored in a contents distribution server into segments and distributing the contents data segments, the contents data being reproducible for a predetermined period of time; a unit for distributing the contents data segments by varying sizes of the contents data segments in accordance with contents processing information notified by a contents reproduction terminal; a unit for receiving and storing the contents data segments distributed by the contents distribution server and reproducing the same in real time; and a unit for notifying the contents distribution server of the contents processing information indicating a processing status of the contents data segments distributed.
