A method for securing data transmitted over a network to an image display device. In one embodiment, the method may include identifying at least one image display device on the network, selecting the at least one image display device for transmission of data, activating a data protection process to generate locked data and transmitting the locked data to the image display device. The method may further include receiving a key to unlock the locked data such that the data is available to the image display device.

Security of data over a network

The present invention provides a method of securing transmission of content over a wireless network. The method may include initiating a relationship between a content source and a display system, establishing a relationship between the content source and the display system including negotiating a shared key and encrypting content for transmission between the content source and the display system.

A data analyzer/classifier comprises using a preprocessing step, and energy minimization step, and a postprocessing step to analyze/classify data.

Energy minimization for classification, pattern recognition, sensor fusion, data compression, network reconstruction and signal processing

A method of controlling a transmission of image data from an image source to an image display device is disclosed, wherein the method includes transmitting the image data from the image source to the image display device, receiving the image data in a buffer on the image display device, reading at least some of the image data out of the buffer for processing by the image display device, monitoring an amount of unprocessed image data in the buffer, transmitting a value representing an amount of unprocessed image data in the buffer from the image display device to the image source, and adjusting the transmission of the image data to the image display device by the image source if the value representing the amount of unprocessed image data meets a preselected condition.

System and method for controlling a transmission of image data to a display device

A method of processing image data is disclosed, wherein the method includes receiving a set of image data values in a device-dependent first color space, comparing the values in the first color space to a look-up table having entries correlating the values in the first color space to integer values in a device-independent second color space, locating in the look-up table the values in the second color space corresponding to the values in the first color space, and converting the values in the first color space to the values in the second color space.

System and method for processing image data for color space conversion

In one embodiment, a method of processing image data for compression is provided, wherein the image data represents an image and includes a plurality of image data values, each image data value representing an appearance characteristic of a pixel of the image. In one embodiment, the method includes determining a variance between n image data values, comparing the variance to a variance threshold to determine whether the variance meets a preselected condition relative to the variance threshold, and if the variance meets the preselected condition, then changing at least one of the n image data values to reduce the variance.

System and method for processing image data

A method of transmitting a plurality of frames of image data over a communications channel from a display image source to a display device is disclosed, wherein the plurality of frames of image data are transferred on a frame-by-frame basis at a predetermined time interval. The method includes encoding at least a portion of a selected frame of image data via hierarchical encoding to form a hierarchically encoded set of image data layers, and sending only a subset of the set of image data layers over the communications channel, wherein the subset of image data layers includes fewer image data layers than the set of image data layers.

A relatively thin-profile projection display device that employs at least two anamorphic components is disclosed herein.

Thin-profile projection system

Geographically distributed conference sites each have a telephone receiver and a dataconferencing appliance connected to a shared voice call network. Each site also has a display device for displaying images comprised of image data produced by an image source. The dataconferencing appliance is connected to a data network that links the sites independently of the voice call network. To initiate a dataconference session between the sites, a voice call session is first established between the telephone receivers via the voice call network. An address negotiation procedure implemented in software or hardware of the dataconferencing appliance is then manually initiated to identify a network access code and communicate it to at least a second one of the sites within the voice call session. The network access code is used to establish a data communication session via the data network for convenient transmission of image data between the sites.

Dataconferencing appliance and system

A method of decompressing a set of subsampled image data is disclosed. The method includes reading a first subset of the subsampled image data into a cache memory and into a buffer, wherein the buffer has an amount of memory equal to or less than the cache memory, calculating chrominance values for at least some pixels of the subset of the subsampled image data to form decompressed image data, and outputting the decompressed image data.

An analyzer/classifier tool () for data comprises use of an energy minimization process () with data transformed by an input process () into one or more input matrices. The data to be analyzed/classified is processed by an energy minimization technique such as individual differences multidimensional scaling (IDMDS) to produce at least a rate of change of stress/energy. Using the rate of change of stress/energy and possibly other IDMDS output, a back end process () analyzes and classifies data through patterns recognized within the data.
