Abstract: A method of method of processing an image includes: determining estimates of parameters of an auto-regressive, parametric model of noise, according to which a current noise pixel is computed combining linear combination of previous noise pixels in a causal neighborhood of the current noise pixel weighted by respective model linear combination parameters with a generated noise sample corresponding to an additive Gaussian noise of model variance parameter; performing a convergence check loop, each iteration including: generating a noise template of noise pixels based on the estimated model parameters, the noise template having predetermined pixel size smaller than the image pixel size; estimating a noise template variance; if the estimated variance is below a first predetermined threshold or above a second predetermined threshold, proportionally decreasing the model linear combination parameters with a predetermined correcting factor, and performing another convergence check loop; otherwise exiting the convergence check loop.

Each channel comprises: an input interface powered by a low-noise power supply arranged to receive a respective modulated video broadcasting input signal within an input frequency band; a single input, dual output distribution amplifier arranged to produce first and second amplified input signals within a satellite broadcasting frequency band and within a cable and/or terrestrial broadcasting frequency band, respectively. A first tuner is configured to receive and downconvert the first amplified input signal to generate a first baseband signal; a second tuner is configured to receive and downconvert the second amplified input signal to generate a second baseband signal; and a demodulator is configured to receive the baseband signals as input and to generate the respective video transport stream.
