An image processing device controls a local resource, retrieves data files from a network, generates partial images from data included in the data files, and displays an image by combining the plurality of partial images. The partial images include first partial images that require access to the local resource and second partial images that do not require such access. Access to the local resource takes place by request and is controlled so that generation of the first partial images requires authentication of the retrieved data files. While authentication is in progress, the image processing device disallows access to the local resource and displays an image by combining the second partial images with a notification image indicating that authentication is being performed.

Image authentication and retrieval processing device and method

The transmission terminal in a wireless communication system includes: a communication unit for intermittently transmitting a radio signal; a transmission-side beacon reception unit; a beacon analysis unit for analyzing the received beacon signal; and a transmission output level change unit for estimating an emission time period of a beacon signal to be received by the transmission-side beacon reception unit on the basis of the beacon period information and the beacon reception time information, thereby obtaining an estimated emission time period; wherein the transmission output level change unit instructs the transmission-side communication unit to transmit the radio signal having a raised transmission output level during at least the estimated emission time period, the raised transmission output level being higher than a transmission output level during a time period other than at least the estimated emission time period.

Responsive to a proxy authentication request from a network terminal, a display for prompting a user to start an authentication operation is performed; authentication data for performing personal authentication are read by a user operation; an authentication request is sent together with the read authentication data to an authentication server; an authentication result is received from the authentication server; the network terminal is notified of the result. When a service requiring personal authentication is used, via a network, a request for proxy authentication can be made from a network terminal lacking an interface for personal authentication to a proxy authentication terminal having an interface for personal authentication, whereby the interface of the proxy authentication terminal can be used to perform the personal authentication.

A receiving device () is provided to allow appropriate clock regeneration even for a VBR TS when a stream including video and audio data, such as an MPEG2 TS, is transmitted or received in real time through a network having jitter. When the received packet data is stored in a memory () and the packet data is output in accordance with time information added to the received packet data, a clock frequency deviation between a sending device and a receiving device is calculated on the basis of the integration result of the amount of the received packets temporarily stored in the memory (), the number of the received packets which have been processed, and the measurement result of the integration time used for integrating the amount of the received packets. A read timing offset of the received packet is obtained on the basis of the calculation result of the clock frequency deviation.

Data receiving device and data receiving method

A management unit () which issues a digital certificate to a new transmission unit () includes a wireless communication section for performing communication in a network () and a wire communication section to which the new transmission unit () can be connected; when the new transmission unit () is wire-connected to the management unit (), it is judged in accordance with the received device type information of the new transmission unit (), whether or not the new transmission unit () is a device having a communication means that can communicate in the network (); and if the new transmission unit is judged as a device having that type of means, the management unit creates a digital certificate by using a device identifier specific to the new transmission unit (), and sends the digital certificate to the new transmission unit ().
