摘要:
A display system is provided which determines an effective image area by automatically detecting a boundary between the effective image area and a non-image area created owing to the difference between the pixel numbers of the camera image sensor and television signal, to thereby display the images on a monitor by adjusting a display size and position suitable for the effective image area, whereby an inappropriate display size and position are avoided from being set while a lighting device for illuminating a camera's field of vision is off. The display system receives a signal notifying about activation of the lighting device from the lighting controller that provides on/off control of the device; the system then determines the effective image area if the device is on, and does not if it is off.

An information processing apparatus in which its function can be improved by installing an additional module to an existing module in a module configuration system. A video information processing apparatus 100, which is an existing module, has the function of reading, from a network module 150 as an additional module, software held in the network module 150. The software held in the network module 150 includes control software for the network module and software for making the control software available to the existing video information processing apparatus 100. The software held in the network module 150 is added to the video information processing apparatus 100, and the network module 150 is operated by the video information processing apparatus 100.

A file transfer method and a file transfer system are provided for making it possible to minimize aggregate waiting time of the whole users for data transfer using a multicast protocol. In the file transfer method of transferring a plurality of program files from a recorder storing a plurality of program files via a network to a plurality of mobile terminals using a multicast protocol, the recorder determines order of transfers of the plurality of program files for the purpose of transferring the plurality of program files in order of digital data files, which is the ascending order of file size of the plurality of program files (step S102), the recorder transfers the plurality of program files on the basis of the order of transfers (steps S104-S109), and the plurality of mobile terminals selectively receives the plurality of program files (steps S204-S207), thereby reducing aggregate waiting time that is a sum total of transfer time of the whole users.

A system for presenting information to passengers in a conveyance, has a computer which stores operation diagram information; a storage medium which stores a plurality of advertisement data items to be presented to the passengers; and an information presenting device. The computer obtains an operation time in each operation section on the basis of the operation diagram information and identification data for identifying the conveyance, and selects and arranges some of the advertisement data items to generate presentation data for continuously presenting information to the passengers throughout a time period corresponding to the operation time. The information presenting device reproduces the presentation data corresponding to each operation section to present the information to the passengers in each operation section of the conveyance.

Provided is a gateway device for interconnecting an IEEE1394 network and an IP network, which automatically detects and operates an AV device connected to the IEEE1394 network from a player device connected to the IP network, thereby enabling the player device to watch and hear contents stored in the AV device. The gateway device interconnects a network, to which an AV/C installed IEEE1394 device is connected, and a network, to which a player device compliant with a UPnP is connected, and includes: a conversion unit for converting Plug-and-Play processing of the IEEE1394 device to each step of Plug-and-Play of the UPnP; a conversion unit for converting an action of a UPnP AV to an AV/C command of the IEEE1394 device; and a stream transfer unit for transferring stream data transmitted from the IEEE1394 device to the IP network.
