20090241157CONTENT DISTRIBUTION SYSTEM, BAND CONTROL MEDIATING APPARATUS, AND BAND CONTROL METHOD - A content distribution system according to the present invention, includes a client terminal, a server, a band control mediating unit provided between the client terminal and the server, and configured to relay a reproduction control protocol data of a content data from the client terminal to the server, and a first band control unit arranged in a first network and configured to control a band on the first network. The band control mediating unit requests the first band control unit to control the band on the first network for a communication path, through which the content data is transferred, based on the reproduction control protocol data.09-24-2009
20100017837METHOD OF SECURING RESOURCES IN A VIDEO AND AUDIO STREAMING DELIVERY SYSTEM - 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.01-21-2010
20100046514MULTICAST COMMUNICATION SYSTEM AND METHOD - 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.02-25-2010
20100100935CONTENT DISTRIBUTION SYSTEM, CONTENT DISTRIBUTION METHOD AND PROGRAM - 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. A session control server extracts the one-time URL from a session control message transmitted from the user terminal, transmits it to the distribution management and unauthorized operation management device, and establishes a session between the content distribution server and the user terminal according to an authentication result performed by using the one-time URL transmitted from the distribution management and unauthorized operation management device and a correlation result obtained by correlating the bandwidth information contained in the session control message transmitted from the user terminal with the bandwidth information transmitted together with the authentication result from the distribution management and unauthorized operation management device.04-22-2010
20100235702TRANSMITTER, FILE DISTRIBUTION SYSTEM, FILE DISTRIBUTION CONTROL METHOD AND FILE DISTRIBUTION CONTROL PROGRAM IN SYSTEM - Intended is to avoid retransmission requests from congesting and data retransmission from being disabled.09-16-2010
20100251333SERVER, AUTHENTICATION SERVER, CONTENT DELIVERY SYSTEM, AND PROGRAM - 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.09-30-2010
20110078283SERVICE PROVIDING SYSTEM, FILTERING DEVICE, FILTERING METHOD AND METHOD OF CONFIRMING MESSAGE - A service providing system is connected to a user terminal via a network, acquires a request message described with an upper layer protocol exceeding three layers for requesting desired data and transmitted by the user terminal, and analyzes the content of a body portion of the message. In the case where unwanted information or unusual information is contained in request content, the unwanted information or the unusual information is eliminated by subjecting the request message to a predefined process.03-31-2011
20110238232ENERGY MANAGEMENT SYSTEM, ENERGY MANAGEMENT APPARATUS, AND ENERGY MANAGEMENT METHOD - An energy management system includes an equipment data management unit which manages charging/discharging loss of a battery and heat radiation loss of an electric water heater, and causes a control unit to perform control to give priority based on the comparison to the energy storage facility more reducing loss and store energy. The energy management system includes a system operation calculation unit which predicts voltage distribution of the next day of a distribution system or demand-and-supply balance amount of the entire system by state monitoring data of a power system, calculates a demand amount increasing target value necessary for avoiding a photovoltaic power generation amount suppression on a consumer end by the voltage distribution of the next day of the distribution system or the demand-and-supply balance amount, and controls the energy storage facilities so as to satisfy the demand amount increasing target value on the consumer end.09-29-2011
