20090241157 | CONTENT 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 |
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 |
20100205236 | SERVICE PROVIDING METHOD, SERVICE PROVIDING SYSTEM, TERMINAL, INFORMATION MANAGEMENT DEVICE, SERVER, AND PROGRAM - It is possible to provide a personalize service for users and a personalize service for each of the terminals owned by users by considering a profile unique to each of the terminals owned by the users and a common profile of respective terminals owned by one user. In response to a service execution request from a terminal, a service is provided according to the unique profile unique to the terminal and a common profile common to all the terminals owned by the user having the aforementioned terminal. | 08-12-2010 |
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 |
20110010537 | DATA RECORDING DEVICE, DATA RECORDING METHOD USING SAME, AND DATA RECORD CONTROLLING COMPUTER PROGRAM - A data recording device is provided to record and redistribute stream data such as TV programs without imposing loads proportional to the number of users. Stream data of a distributed program is collated by a recording range judging section | 01-13-2011 |
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 |
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 |
20120242700 | CONTENTS PLAYBACK APPARATUS, CONTENTS PLAYBACK METHOD, AND COMPUTER PROGRAM - A contents playback apparatus and the like are provided which allow a user to promptly designate a desired portion when displaying a part of a content in an expanded manner, and are thus excellent in operability. A contents playback apparatus includes an associating unit and a playback unit. The associating unit generates association information for a plurality of characteristic portions contained in a content by referring to priority orders of the respective characteristic portions relative to each other, the association information associating each of the characteristic portions individually with a predetermined operation key of an input device included in the apparatus in accordance with the priority orders. The playback unit plays back, in response to detecting an operation of an operation key during display of the content, the characteristic portion corresponding to the operation key in an expanded display mode, in accordance with the association information. | 09-27-2012 |
