Abstract: Disclosed is a method, circuit and system for communicating data. A data value to be transmitted from a data source transmitter or transceiver to a downstream receiver or transceiver may be Shannon mapped, by functionally associated processing/mapping logic, to a point on a shape within a higher dimensional plane. Different portions of the shape, for example branches of a spiral, may be designated by a portion or branch number. Coordinates of the Shannon mapping, or another descriptors, of the Shannon mapped point may be transmitted using analog transmission methods. A set of data values may be Shannon mapped and transmitted to a downstream receiver/transceiver in series. For each set of mapped and transmitted data values, processing logic may calculate a branch ambiguity resolution factor. The branch ambiguity resolution factor for each set of values may be transmitted to the downstream receiver/transceiver before, after or with the data values.

Abstract: Disclosed are methods, circuits, devices and associated executable code for facilitating transmission, reception and presentation (e.g. rendering) of video information/signals on a video display unit such as a flat-screen display, a touchscreen and/or a tablet computing platform. There may be provided a video display unit adapted to receive video signals through two or more video signal paths, wherein one of the signal paths (i.e. a first signal path) may be a wired signal path. Another signal path (i.e. a second signal path) may be a wireless signal path. The display unit may be matched or paired to a matched computing platform. The paired matched computing platform may send video signals to the display unit along the wired signal path, e.g. when the display unit is docked with the matched computing platform. The paired matched computing platform may send video signals to the display unit along the wireless signal path, e.g. when the display unit is disconnected from the matched computing platform.

Abstract: An apparatus and method for wireless transmission of uncompressed HDTV video overcomes the challenges of sending vast amounts of information over a wireless link. This is achieved by direct mapping of transformation coefficients of the video components to communication symbols, such as OFDM symbols. A main portion of the important transform coefficients, for example the MSBs of the coefficients representing lower frequencies of each of the video components, and in particular the quantized values of the lower frequencies components, are sent in a coarse representation using, for example, QPSK or QAM. The coefficients representing higher frequencies of the video components, and the quantization error values of the lower frequencies components, or some, non-linear transformation thereof, are sent as pairs of real and imaginary portions of a complex number that comprises a point in a fine constellation. The invention further provides a delay-less and buffer-less implementation of transmitter and receiver pairs.
