Abstract: In a network system provided with a plurality of wireless networks each having an access point and one or more wireless communication devices wirelessly connectable to the access point, and a predetermined network adapted to connect the access points of the plurality of wireless networks to each other, a predetermined wireless communication device issues inquiry request of the information to the other wireless communication devices, and then receives the inquiry response from each of the other wireless communication devices receiving the inquiry request, thereby receiving the BSSID. The BSSID thus received is accumulated in the first information table. By searching for the BSSID identical to the BSSID of the wireless network to which the predetermined wireless communication device belongs among the BSSID stored in the information table, the predetermined wireless communication device can detect the wireless communication device connected to the predetermined wireless network as the adjacent projector.

Abstract: An image generating apparatus includes a timepiece determining section determining whether or not the setting of an internal clock is normal, a certificate determining section determining whether or not a received electronic certificate from a communication target apparatus is valid based on the setting of the internal clock, a communication section performing communication for authentication with the communication target apparatus if the certificate determining section determines that the received electronic certificate is valid and receiving image information from an image supplying apparatus belonging to a network to which the communication target apparatus belongs or the communication target apparatus, a control section making the communication section perform communication for authentication irrespective of whether or not the received electronic certificate is valid if the timepiece determining section determines that the setting of the internal clock is not normal, and an image generating section genera

Abstract: A projector including: a communication section; a storage section which stores initial projection target data, updated projection target data, layout data and others; an update request reception section which receives an update request from PC via the communication section, and sequentially writes update request data indicating details of the update request into the storage section; an update section which updates the updated projection target data based on the update request data; a web information generation section which causes the communication section to transmit web information to PC based on the updated projection target data and the layout data; an image generation section which generates an image based on the updated projection target data; and a projection section which projects the image.

Abstract: A wireless communication system performs ad-hoc mode communication, wherein a first terminal includes an identification information storing section, an IP address storing section, an SSID generating section generating a service set identifier, a beacon signal generating section generating a beacon signal including an SSID, and a priority information updating section updating priority information, and the second terminal includes an SSID acquiring section acquiring the SSID from the beacon signal, memory storing the SSID, an SSID selecting section selecting one SSID based on the priority information, an IP address acquiring section acquiring the IP address of the first terminal from the selected SSID, and a communicating section making a connection to the first terminal by using the acquired IP address.

Abstract: A communication system which communicates data through communication between a first communication device and a second communication device having common network identification information, wherein a first communication device includes a first communication unit which communicates data to and from other communication device having the common network identification information, a first attachment unit to which a storage device is detachably attached, an issuing unit which obtains network identification information of other communication device and issues network identification information not coinciding with the network identification information of this communication device, and a writing unit which writes the network identification information issued by the issuing unit to the storage device attached to the first attachment unit.

Abstract: The disclosure is directed to image display system and apparatus. In one example, a system comprises a plurality of display apparatus each having a display area. The display apparatus are configured to display images based on image information supplied from a processing unit. The processing unit is configured to receive information descriptive of the display area for each of the plurality of display apparatus, manage integrated screen area information for the plurality of display apparatus based at least on the information descriptive of the display area for each of the plurality of display apparatus, and generate image information from the integrated screen area information for each of the plurality of display apparatus regardless of whether each of the display apparatus is operatively connected to the processing unit.

Abstract: A projector including: a communication section; a storage section which stores initial projection target data, updated projection target data, layout data and others; an update request reception section which receives an update request from PC via the communication section, and sequentially writes update request data indicating details of the update request into the storage section; an update section which updates the updated projection target data based on the update request data; a web information generation section which causes the communication section to transmit web information to PC based on the updated projection target data and the layout data; an image generation section which generates an image based on the updated projection target data; and a projection section which projects the image.
