A system consisting of a plurality of terminals storing image data and an image displaying device which are connected with each other through a network capable of two-way communication has the disadvantage of decreasing in throughput on account of slow image data transfer over the network. The image displaying device performs two-way communications with each of the terminals by a communication means at the display device side. Also, the image displaying device acquires image data from a relevant terminal while instructing other terminals to suspend transmission by the image data acquisition controlling means, thereby suspending transmission of image data. The image displaying device displays images by the image displaying means based on the thus acquired image data.

Image display system, image display device, and image display method

In one embodiment, an image display device comprises a first USB port, a writing unit, and a display unit. The writing unit writes a wireless setup information of the image display device to a predetermined USB memory if the predetermined USB memory is attached to the first USB port. The display unit displays a predetermined message if the writing unit finishes writing the wireless setup information to the predetermined USB memory. The display unit displays an image data sent from an image supply device using the wireless setup information read by the image display device from the predetermined USB memory, if the predetermined USB memory is attached to a second USB port of the image supply device.

A network-connectable projector having a first CPU that executes a web application program stored in a first memory, and a second CPU that controls a working state of the projector, based on working state information stored in a second memory. The second CPU obtains the working state information from the second memory, and transfers the information to the first CPU. The first CPU distributes the web page information including the working state information received from the second CPU to the web client upon receipt of the request from the web client. The first CPU makes the second CPU control the working state of the projector, based on control information that is sent back from the web client and is related to performance control of the projector.

An image/sound supply device repeatedly supplying sound data and image data in such a manner that intervals between transmission start points of the sound data become constant, includes: a block data extraction section extracting first block data including data with a difference between two frame images with a time lag; a block data dividing section dividing the first block data into second block data with a data amount equal to or smaller than a second data amount when a data amount of the first block data is larger than the second data amount; a sound data output section outputting the sound data with a first data amount; and a block data output section outputting the first block data subsequently to the sound data when the first block data is not divided, and outputting the second block data subsequently to the sound data when the first block data is divided.

An image display systemincludes a projector PR, a computer PCand a USB memory Uwhich can be connected in an ad-hoc mode by using a wireless LAN. When a user connects the USB memory Uto a USB interfaceof the projector PR, the projector PRwrites network setup information in a setup information storage areaof the USB memory U. Then, when the user removes the USB memory Ufrom the USB interfaceand connects it to a USB interfaceof the computer PC, the computer PCperforms network setup by referring to the network setup information and establishes connection to start projection by an automatic start program.

An image transfer apparatus includes a display configured to display multiple sets of content. A display image data generator is configured to generate display image data for each of the content, at least part of the content being displayed on the display. A storage controller is configured to relate connected image projection apparatus to the generated display image data and store the display image data related to the image projection apparatus in a storage device. A transfer unit is configured to transfer the display image data to the corresponding image projection apparatus.
