A remote activating device remotely activates a device to be activated connected to a first network and a second network. The remote activating device includes a first interface connected to the first network, a second interface connected to the second network, an arrival confirmation processing unit that transmits an arrival attribute confirmation signal to the device to be activated using the first interface and confirms whether or not the arrival attribute confirmation signal has arrived at the device to be activated, and a judging unit that decides the first interface as an activation signal transmitting interface when the arrival attribute confirmation signal has arrived at the device to be activated and decides the second interface as the activation signal transmitting interface when the arrival attribute confirmation signal has not arrived at the device to be activated.

Remote activating device

There is provided with a mixed video delivering apparatus, including: a video receiving unit receiving first to Nth encoded video data from first to Nth terminals; a decoding unit decoding the first to Nth encoded video data; a video mixing unit mixing first to Nth decoded video data to obtain mixed video data to be transmitted to a terminal 'A' out of the first to Nth terminals; an encoding parameter storage storing first to Nth encoding parameters which are used for encoding the first to Nth videos by the first to Nth terminals; an encoding parameter selecting unit selecting an encoding parameter which is used by any one of terminals other than the terminal A; an encoding unit encoding the mixed video data with a selected encoding parameter to obtain encoded mixed video data; and a video transmitting unit transmitting the encoded mixed video data to the terminal A.

Mixed video delivering apparatus and method, and computer storage medium

There is provided with a video display apparatus comprising: a receiving unit configured to receive a composite video image generated from a plurality of video sources; a display unit configured to display the received composite video image; an area manager configured to store area information pieces; a position specification unit configured to specify a position on the composite video image; an area selection unit configured to select an area information piece from the area information pieces; an area display unit configured to provide information indicating the area represented by the selected area information piece to the display unit so as to superpose the information on the displayed composite video image; an area change unit configured to change the information; an area information update unit configured to update the selected area information piece; and a transmission unit configured to transmit an update control signal containing the area information piece after update.

Video display apparatus, video composition delivery apparatus, and system

A communication apparatus which is connected to networks including first network of first security level which is lowest security level and second network of second security level, and is wirelessly connected to terminal receiving terminal identifier and password which designates one of networks, from terminal, selecting one of first security level and second security level based on an authentication result of terminal, terminal identifier, and password, forwarding, when second security level is selected, data item which is transmitted from terminal and is encrypted using cryptographic algorithm and cryptographic key to second network, and forwarding, to terminal, data item which is transmitted from second network and addressed to terminal, and forwarding, when first security level is selected, data item transmitted from terminal to first network, and forwarding, to terminal, data item which is transmitted from first network and addressed to terminal.

Communication apparatus and method

In the disclosed information delivery scheme for delivering WWW information provided by information servers on the Internet to mobile computers connected to the Internet through a wireless network, a plurality of cache servers capable of caching WWW information provided by the information servers are provided in association with the wireless network. The cache servers can be managed by receiving a message indicating at least a connected location of a mobile computer in the wireless network from the mobile computer, selecting one or more cache servers located nearby the mobile computer according to the message, and controlling these one or more cache servers to cache selected WWW information selected for the mobile computer, so as to enable faster accesses to the selected WWW information by the mobile computer. Also, the cache servers can be managed by selecting one or more cache servers located within a geographic range defined for an information provider who provides WWW information from an information server, and controlling these one or more cache servers to cache selected WWW information selected for the information provider, so as to enable faster accesses to the selected WWW information by the mobile computer.
