[Object] To provides a controller capable of switching a video so that the video is not distorted on the receiving side when the video is transmitted using IP multicast [Solution] There is provided a controller including a bandwidth reservation unit configured to, when an instruction given to a receiving device that receives a first video stream transmitted via IP multicast to receive a second video stream after receiving the first video stream is acquired, acquire information on a status of a network topology and a transmitted video stream and to reserve a network bandwidth for transmitting the second video stream in addition to the first video stream, and a reception instruction unit configured to send out an instruction to receive the second video stream to the receiving device by using the network bandwidth reserved by the bandwidth reservation unit.

Controller, control method, computer program, and video transmission system

A delivery server includes a content output unit configured to output content, a delivery request reception unit which receives a delivery request transmitted from a client terminal connected to a network, a determination unit which determines whether the content is to be delivered to the client terminal in response to the delivery request when the delivery request is received using the delivery request reception unit, and a transmission unit which transmits the content output from the content output unit to the client terminal when the determination unit determines that the content is to be delivered, and transmit the content output from the content output unit to a booster server connected to the network and further transmit a transfer command including information on the booster server to the client terminal when the determination unit determines that the content is not to be transmitted.

Delivery server, content delivery method of delivery server, booster server, content delivery method of booster server

MTID of a terminal apparatus is preliminarily registered into a database of an ISP. In step S, when a power source of the terminal apparatus is turned on first, (MTID=B) is transmitted from the terminal apparatus to a router. A transmission signal is received by the router and (HGWID=A, MTID=B) is transmitted from the router to the ISP. If (HGWID=A, MTID=B) has been registered in the database, the ISP transmits a permission message in step S. In step S, an IP address for a new terminal apparatus is allocated and the new terminal apparatus can participate in a homenetwork. If (HGWID=A, MTID=B) is not registered, a refusal message is sent to the router.

Network system

A delivery server, includes: a content output unit outputting a content; a delivery request receiving unit receiving a delivery request transmitted from a client terminal connected to a network; a determination unit determining whether the content can be delivered to the client terminal in response to the delivery request when the delivery request is received by the delivery request receiving unit; and a transmitting unit delivering the content outputted from the content output unit to the client terminal of a transmission source of the delivery request received by the delivery request receiving unit when it is determined that the delivery can be performed by the determination unit, and transmitting the content outputted from the content output unit to a multicast server connected to the network as well as transmitting a transfer command on which information of the multicast server is put to the client terminal of the transmission source of the delivery request received by the delivery request receiving unit when it is determined that the delivery is not able to be performed by the determination unit.

A service providing system is provided which enables the users of an information transmission service in which information is sent and received in real time over a network to recognize their respective environment and conditions for provision of their own information. The service providing system () includes a service provider () including a communication server (), a Web server () and a DB server () and a plurality of communication terminals () connected to the service provider () via the network, and it provides an information transmission service in which information is provided from one of communication devices to the other, or vice versa, in real time. The communication terminal () at the information provider first registers explanatory information, such as content, offering price, etc. of offered information to be provided into the DB server (), and updates the information registered in the DB server () to a log-in status when the information provider has become able to provide the information in real time; and the Web server () updates the Web page at each time so that the explanatory information having thus been in the log-in status will be included in choices.

Service managing apparatus and method, and service providing system and method

A communication control apparatus selects an optimum terminal for an authentication device among a plurality of terminals that have completed authentication of the authentication device via wireless communication. The communication control apparatus has an information acquiring unit and a selecting unit. The information acquiring unit acquires address information and capability information of each of the plurality of terminals and identification information of the authentication device from each of the plurality of terminals. The selecting unit selects the optimum terminal having a capability of handling data addressed to the authentication device among the plurality of terminals on the basis of the capability information of the plurality of terminals and the identification information of the authentication device acquired by the information acquiring unit, when the address information and capability information of the plurality of terminals are acquired by the information acquiring unit.

Communication control apparatus and communication control system

A call apparatus, a call method and a call system, are disclosed, in which the problem otherwise caused by fixed setting of the sound volume level of the BGM or the effect sound with respect to the call voice may be overcome. A decoded output of a decoder(PCM data) is multiplied in a gain adjustment unitwith a gain coefficient k, as the SE sound volume level as set by a user. A multiplication output of the gain adjustment unitis sent to an adder. The decoded output of a decoderis multiplied in a gain adjustment unitwith a gain coefficient k, as the BGM sound volume level, as set by the user. A multiplication output of the gain adjustment unitis sent to an adder. The addersums the multiplication outputs of the gain adjustment unitsandand sends a sum output to an encoder

Call method, call apparatus and call system

A transmitting-end terminal device transmits an electronic mail including large-size data such as video data to a transmitting-end cache via a transmitting-end router. The transmitting-end cache temporarily stores the received data. A POB server authenticates a user of the transmitting-end terminal device and determines whether a receiving-end terminal device can receive the electronic mail. If the authentication of the user is successful and if it is determined that receiving-end terminal device can receive the electronic mail, the transmitting-end cache transmits the electronic mail directly to the receiving-end cache without passing it through the POB server. The receiving-end cache stores the received electronic mail and transmits a message, indicating that the electronic mail has arrived, to the receiving-end terminal device. In response to a request issued by the receiving-end terminal device, the receiving-end cache supplies the electronic mail stored therein to the receiving-end terminal device.
