TV-signal degradation compensation system (70; 80) comprising: at least one line for transporting a TV-signal from an input side to an output side, measurement means (73, 74) on each of the lines for measuring at least two signal characteristics of the TV-signal on that line, a programmable processing means (75; 83) connected to the measurement means and provided for comparing the measured signal characteristics with corresponding programmable reference values and determining a signal quality from each comparison, signal degradation compensation means (78, 79; 81, 82) on each of the lines, provided for compensating degradation of the transported TV-signal on the basis of the signal qualities determined by the programmable processing means.
