Abstract: A system and method for enabling a wireless terminal to access and operate ubiquitous devices (“UDs”), such as televisions, DVD players, etc. The system comprises a server coupled to access points and UDs via a LAN or a WLAN. Each access point is associated with both a map of an associated area and an overlay indicating the location of the UDs within that area. In response to wireless terminal requests relayed by an access point, the server retrieves the map and overlay associated with the access point, and transmits that data to the terminal for display. Alternatively, a list of UDs may be transmitted. Selection of a UD from the display causes an image of the UD's control panel to be displayed, from which the device may be remotely controlled by the user. A mechanism is also provided to permit users to display maps of areas other than the one in which the user is currently located to permit remote control of UDs in such areas.

Abstract: A system and method are disclosed for improving the remote display of graphics images by the redirection of rendering and the optional use of image data compression. Instead of sending graphics commands over a network and rendering on a remote computer system, graphics commands may be automatically redirected by modified OpenGL functions to local graphics devices without explicit involvement by the graphics application. The modifications to a set of the OpenGL functions on the local system are transparent in the normal mode of rendering and displaying locally. After an image is rendered locally, it may be read back and sent across the network. A standard X Server on the remote system may be sufficient to support this methodology. An X Extension for data decompression on the remote system, however, may allow for more efficient image transmission through the use of image data compression.

Abstract: A method for interfacing to ultra-high resolution output devices. The basic idea of the present invention is to subdivide an ultra-high resolution display screen into narrow strips or column subsections, thereby enabling the mapping of multiple pixel interfaces to it. In this manner, the full pixel display is completely mapped. As such, multiple image generators are able to create in parallel their specific narrow strip of the full pixel display using view frustum culling, which is known by those of ordinary skill in the art. It should be appreciated that an interface in accordance with the present invention is not tied tightly to a scanning architecture. As such, this keeps a level of abstraction between the image generator and the many different types of display devices. Furthermore, since this interface is by design a rasterization interface, more image generators and less expensive image generators can be used for driving the display device.
