  • Publication number: 20140028907
    Abstract: A digital networked studio and the needed software services to allow the use of the system for monitoring the creation and distribution processes of real-time created content is described. Distribution problems are solved using an off-the-shelf network, e.g. using an IP based or similar data protocol, such as an IP network based distributed system architecture to bring the display controller functionality closer to the source and to replace proprietary busses used for transporting video, audio, RGB, graphical information and/or metadata with building blocks based on standard IP and compression technologies. A characteristic of such a network is to use unicast, multicast and/or broadcast technologies (based on network addresses) and to route data from one address to another. The network provides redundancy in case any of the digital generation units.

The user has control of the design and content of the message including font, background, pictures and sound; there is no need to contact another person or organization such as a radio or TV station to post the message; and the user can target a specific audience if so desired. Messages are posted on user-specified electronic bulletin boards for a certain time slot and can be applied to a variety of services such as highway advertising boards, Amber Alerts, and campus message boards, to name a few.

  • Patent number: 7878664
    Abstract: A projector includes a projecting module for projecting a projecting image on a screen panel, an image sensor for capturing an image of an object which is located outside of the projecting module and faces toward the lens module, a light director, and a controlling unit. The projecting module has a lens module and a light source for emitting light transmitting through the lens module. The light director is movable between a first position where the light director is located outside of a light path associated with the lens module, and a second position where the light director is configured for directing light of the object through the lens module to be incident on the image sensor. The controlling unit controls the light director to move between the first and second positions.

  • Patent number: 7777811
    Abstract: An enlarged image is displayed using a plurality of television sets. A television set serving as a master device and television sets serving as slave devices convert an input image into partial enlarged images and display the resultant partial enlarged images so that the partial enlarged images displayed on the respective television sets form, as a whole, a complete enlarged full image. The master device and slave devices perform mutual authentication with each other. If the authentication is successfully passed, the operation mode is set so that displaying of an enlarged image is allowed.

  • Patent number: 7738036
    Abstract: The present invention provides method for producing a substantially seamless video image on a display surface. The method comprises the steps of separately projecting at least a first and a second video image onto a display surface such that a seam is defined by overlapping portions of said first and second video images. Inside the seam, the brightness of the first video image and the brightness of the second video image are adjusted electronically so as to provide a uniform brightness profile.

  • Patent number: 7679690
    Abstract: A geometry correction module for a fixed pixel raster projector to project an image onto a projection surface is provided. The geometry correction module includes a receiver and a geometry corrector. The receiver collects an input pixels grid that represents an input image. The geometry corrector generates an output pixels grid representing an output image that compensates for the geometry of the projection surface by repositioning image data interpolated from at least two input pixels. The output image represents an altered input image that when projected onto the projection surface will display a correctly proportioned input image. A method of correcting geometry distortion when projecting an image is also provided.

  • Publication number: 20090273705
    Abstract: In a television broadcast display apparatus, a mobile device is configured so that images can be displayed on a second screen when audio signals are outputted from the mobile device. A control unit switches between television output status and mobile device output status according to a user operation inputted to a remote-control transmitter. The mobile device output status is a state where audio corresponding to the audio signals received from the mobile device attached is output from speakers. A mobile device holder supports the attached mobile device detachably in such a position that when a user views from an expected viewpoint where a first screen is visible, the second screen is also visible, and the second screen is located adjacent to the first screen.

  • Patent number: 7592970
    Abstract: A tiled display device is formed from display tiles having picture element (pixel) positions defined up to the edge of the tiles. Each tile includes a memory which stores display data, and pixel driving circuitry which controls the scanning and illumination of the pixels on the tile. The tiles are formed in two parts, an electronics section and a display section. Each of these parts includes connecting pads which cover several pixel positions. Each connecting pad makes an electrical connection to only one row electrode or column electrode. The connecting pads on the display section are electrically connected and physically joined to corresponding connecting pads on the electronics section to form a complete tile.
