20100017837 | METHOD 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 |
20100046514 | MULTICAST 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 |
20100058422 | VIDEO AUDIO STREAM DISTRIBUTION SYSTEM, DISTRIBUTION METHOD, AND DISTRIBUTION PROGRAM - 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 ( | 03-04-2010 |
20100100935 | CONTENT 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 |
20100251333 | SERVER, 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 |
20110078283 | SERVICE 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 |
20110106928 | PROCESSING STATE MANAGEMENT DEVICE, PROCESSING STATE MANAGEMENT METHOD, AND PROGRAM - A processing state management apparatus holds state information indicating the state of transaction processing in a distribution server as in progress after the processing state management apparatus connected to the distribution server requests the transaction processing to the distribution server which executes the transaction processing to register or delete contents to be distributed until the processing state management apparatus receives the notification of completion of the transaction processing from the distribution server. | 05-05-2011 |
20110129298 | PHOTOCATALYST MATERIAL, PROCESS FOR PRODUCING THE PHOTOCATALYST MATERIAL, AND METHOD FOR DECOMPOSING CONTAMINANT USING THE MATERIAL - This invention provides a photocatalyst material, which can be produced at low cost without using platinum, particularly a visible light response-type photocatalyst material, a material having a photocatalyst mechanism not possessed by the conventional photocatalyst material, a process for producing the material, and a method for decomposing a contaminant using the material. The photocatalyst material comprises a) an oxide of a first metal and b) an aqua complex salt of a second metal. In this case, for the oxide of a first metal, the redox potential of a conduction band lower end in the oxide is on a rather negative side than 0.2 V (a value as measured at pH=0, vs. reference electrode potential). For the aqua complex salt of a second metal, the redox potential of a second metal ion in the aqua complex salt is on a rather negative side than 3.0 V (a value as measured at pH=0, vs. reference electrode potential). In the material, the aqua complex salt of a second metal is chemically adsorbed on the oxide of a first metal. | 06-02-2011 |
20110167163 | COMMUNICATION SYSTEM, METHOD, DEVICE AND PROGRAM - A first communication apparatus executes a session control protocol thereby to determine a session identifier which identifies a session for media-related protocols for transferring the data when the session is established, and thereafter executes the media-related protocols thereby to perform communications for transferring the data on the session. A second communication apparatus executes the session control protocol thereby to establish a session for the media-related protocols with the first communication apparatus, and thereafter executes the media-related protocol thereby to perform communications for transferring the data with the first communication apparatus on the session. | 07-07-2011 |
20110280546 | TIME-SHIFTED VIEWING SYSTEM, TIME-SHIFTED VIEWING METHOD, AND TIME-SHIFTED VIEWING APPARATUS AND PROGRAM - A transmitting section of the present invention initiates transmission of a second video continuously after completing transmission of a first video being transmitted, in a case that a reproduction position of the first video being transmitted is beyond an end point of the first video, when a video recording start time of a second video stored in a video storage section and a video recording end time of the first video being transmitted coincide within a predetermined time difference. | 11-17-2011 |
