Abstract: A service provider server has management means which manages a user ID corresponding to a service user and a device IDs corresponding to an information processing terminals of the service user in association with each other.

Abstract: A content distribution system. A distribution management and unauthorized operation management device generates a one-time URL by using URL of content information specified by a user terminal and transmits the one-time URL and bandwidth information concerning the content information to the user terminal.

Abstract: It is possible to provide a video audio stream distribution system, a distribution method, and a distribution program which can improve the stream switching speed during zapping and suppress the actually used network resource in streaming for which QoS is guaranteed. Zapping destination means (211) predicts a stream required for the next distribution request and band managing means (209) instructs only band allocation for the predicted stream to band control means (205) before a distribution request is made by an actual zapping operation.

Abstract: The present invention aims to realize a system and method of reliably performing multicast communication via a bandwidth-guaranteed network, and provides a multicast communication system for performing multicast communication via a bandwidth-guaranteed network, the system including: a multicast proxy response device added with a group address destination identifier; and a multicast client, wherein the multicast proxy response device transmits a session connection request to the group address destination identifier of the multicast proxy response device when starting reception, the multicast proxy response device which has received said session connection request transmits a session connection response to said multicast client, and the multicast client receives multicast data through a bandwidth secured in the bandwidth-guaranteed network by the session connection response.

Abstract: A video and audio stream is predicted that is to be selected for reception next to a video and audio stream that is being received by the terminal or that is after a video and audio stream that has been selected for reception by the terminal. Resources necessary for delivering the predicted video and audio stream, in addition to resources necessary for the video and audio stream that is being received by the terminal or that has been selected for reception by the terminal, are secured in advance before a user of the terminal selects the next video and audio stream. The predicted video and audio stream is not delivered to the terminal before it coincides with a video and audio stream that is selected at the next zapping.

Abstract: This invention provides a method for measuring human megalin that can be performed in a simpler manner within a shorter period of time than is possible with conventional techniques, and that can also quantify human megalin. This invention also provides a method that enables diagnosis of functional diseases, which are specific to cells, tissues, or organs, in a site-directed manner at an early stage. Measurement of human megalin enables detection of a disease in an organ in which megalin expression is observed.

Abstract: A first session proxy device is disposed between a client device having no control protocol for bandwidth securing sessions installed therein and a bandwidth guaranteed network. A second session proxy device is disposed between a server device having no control protocol for bandwidth securing sessions installed therein and the bandwidth guaranteed network. When the client device and the server perform communication over the bandwidth guaranteed network, the first session proxy device establishes a bandwidth securing session in the bandwidth guaranteed network, in place of the client device, while second session proxy device establishes a bandwidth securing session in the bandwidth guaranteed network, in place of the server device.

Abstract: A distortion compensator compensates for distortion arising in an amplifier that amplifies a signal with improved efficiency. The distortion compensator includes a signal level detector which detects the level of a signal to be amplified by an amplifier, a distortion compensation execution unit which executes distortion compensation on the signal to be amplified according to a mode of distortion compensation corresponding to the signal level detected by the signal level and a correspondence between signal levels and distortion compensation control values as pairs, a distortion compensation control value correspondence updater which updates the correspondence between the signal levels and the distortion compensation control values used in the execution of distortion compensation, and a distortion compensation control value number controller which controls the values of stipulated parameters.

Abstract: The present invention includes a production managing server and a plurality of staff terminals. The production managing server manages production information for each staff member engaged in production of an advertisement. Each of the plurality of staff terminals transmits a report indicating completion of work contents to the production managing server. When receiving the report from any one of the terminals, the production managing server notifies the other staff terminals of an instruction to advance a subsequent process.

Abstract: This invention is intended to improve the efficiency of distortion compensation in a distortion compensator that compensates for distortion arising in an amplifier that amplifies a signal. Signal level detection means 1 detects the level of a signal amplified by the amplifier 5. Distortion compensation execution means 2-4 executes distortion compensation with respect to the signal amplified by the amplifier 5 by a mode of distortion compensation corresponding to the signal level detected by the signal level detection means based on a correspondence between signal levels and distortion compensation control values that determines the mode of distortion compensation. Distortion compensation control value correspondence update means 6 updates the correspondence between signal levels and distortion compensation control values used in the execution of distortion compensation by the distortion compensation execution means based on the signal amplified by the amplifier.
