发明名称 METHOD FOR CONTINUOUSLY CONTROLLING THE QUALITY OF DISTRIBUTED DIGITAL SOUNDS
摘要 The invention concerns a method for continuously controlling the quality of distributed digital sounds broadcast by radio or television on a digital channel. The method consists in temporally breaking down (1) the digital signal into sequences (Sn) of samples; carrying out a spectral analysis (2) of each sequence to observe the variations in energy and envelope of the digital signal and calculating a global quality index and in calculating (3) on the basis of the global quality index a final gated and continuous quality index representing the quality of the digital signals. The invention is applicable to the continuous control of the quality of distributed sounds.
