The present invention presents fully noncausal predictive encoding and decoding methods for image, video and other signal coding. The presented noncausal predictive image coding methods largely reduce the prohibitive computational cost of the prior invention. The presented noncausal signal encoding method comprises: (1) splitting the source signal into a plurality of noncausal coding units; (2) extending each noncausal coding unit with the selected extension type; and (3) encoding each noncausal coding unit with the selected intra-unit noncausal predictor and intra-unit noncausal predictive encoding method.

An automatic gain control (“AGC”) system. The system includes a first multiplier, an envelope detector, a summation module, a filter module, a convergence module, and a feedback module. The convergence module includes a convergence control module and a second multiplier. The feedback module includes an accumulator, a scalar multiplier module, and a third multiplier. The system is configured to adjust or modify its convergence speed according to the state of convergence of the AGC system, and the convergence speed of the AGC system is substantially independent of a signal level of the received signal.

Remote apparel fitting has long remained a problem technically and commercially since the start of online e-commerce. Various virtual fitting rooms have been disclosed in prior inventions and tried, where simulated apparel fitting results are generated from computer models. As a contrast, the present invention discloses systems and methods for remote robotic apparel fitting, shopping and showing, where the apparel fitting results are produced by a real piece of apparel worn by a body matched robotic fitting apparatus, and the apparel fitting results are captured and watched by a shopper through one's personal remote vision provided by a remote vision apparatus.

A method of controlling a digital demodulator (922) coupled to an equalizer (930) includes the steps of generating an equalizer value (930A), filtering (944) the equalizer value (930A) to obtain a post filter output, subtracting the equalizer output signal (930C) from the decoded data (930D) and generating an error value (924A). The post filter output is correlated (948) with the error value (924A) to obtain a correlated value (74A). A control signal is developed from the correlated value and is used to adjust the digital demodulator (922).

A method of controlling a feedforward filter of an equalizer includes the steps of generating a complex representation of an output of the feedforward filter and generating a representation of a decision from an output of the equalizer. The complex representation and the decision representation are correlated to obtain a phase error estimate. A phase correction value is generated based on the phase error estimate and used to adjust the phase of the output of the feedforward filter.

The present invention presents the HD video transmission methods, which transmit the HD video into transform domain. In an aspect of the present invention, at the HD video transmitter the HD video is transformed by a multi-dimensional transform. Through the discrete-time continuous-valued or quasi-continuous-valued modulation, the obtained coefficients in transform domain are preferably carried in parallel in a multiple-access channel in time-domain to the HD video receiver.

A method of controlling sampling frequency and sampling phase of a sampling device from a value generated by an equalizer coupled to the sampling device includes the steps of generating a complex representation of the value developed by the equalizer and generating a representation of a decision from an output of the equalizer. The complex representation and the decision representation are correlated to obtain a sampling error estimate. The sampling error estimate is used to adjust the sampling frequency and sampling phase of the sampling device.
