    Abstract: A method for decoding a Manchester-II encoded DISPLAYPORT compatible signal is provided. In this method, several counters are reset. A unit interval (UI) counter is incremented for each UI received upon receipt of a valid UI, and the value of the UI counter is compared to a plurality of threshold values after the UI counter is incremented. When the value of the UI counter exceeds each of the threshold values, for each clock cycle, a sum counter is incremented corresponding to the exceeded threshold value, and a plurality of window lengths are calculated, where each window is calculated based at least in part on the value of one of the sum counters at predetermined values of the UI counter.

    Abstract: A method and system of lossless adaptive Golomb/Rice (G/R) encoding of integer data using a novel backward-adaptive technique having novel adaptation rules. The adaptive G/R encoder and decoder (codec) and method uses adaptation rules that adjust the G/R parameter after each codeword is generated. These adaptation rules include defining an adaptation value and adjusting the G/R parameter based on the adaptation value. If the adaptation value equals zero, then the G/R parameter is decreased by an integer constant. If the adaptation value equals one, then the G/R parameter is left unchanged. If the adaptation value is greater than one, then the G/R parameter is increased by the adaptation value. In addition, the adaptive G/R encoder and method include fractional adaptation, which defines a scaled G/R parameter in terms of the G/R parameter and updates and adapts the scaled G/R parameter to slow down the rate of adaptation.

    Abstract: Binary signals that are transmitted by Manchester coding and frequency modulation are demodulated based on the behavior of the phase or complex vector value of the received signal. The polarities of the information bits may be determined by measuring the phase excursions in the middles of the Manchester symbols. A phase reference is established from a plurality of candidate phase references as a basis for comparison of the mid-symbol phase. The phase can be measured at the start-points and end-points of the symbols and averaged, or measured a plurality of times during each symbol period to generate a reference phase.
