Abstract:
A method for processing interfered-with signals, said signals composed of data representing a plurality of groups of a plurality of subbands comprising a media signal, said method comprising the steps of:decoding at least one group of subband signals; storing in a memory a signal portion of at least one group of subbands of processed signal data; detecting interfered-with signal sections of at least one group of subbands with an analyzer; masking said interfered-with signal sections to form at least one masked subband group signal section through usage of a selectable switch to replace said original interfered-with signal sections with a selected masking strategy by choosing from among two or more of the following alternatives: (i) transmitting said interfered-with signal section without correction; (ii) muting said interfered-with signal section; (iii) replacing said interfered-with signal section with said processed signal portion of at least one group of subbands stored in said memory; or (iv) replacing said interfered-with signal section with an estimated signal generated by an estimator; whereby said at least one masked subband signal section is outputted from said switch as said processed signal data; and whereby said processed signal is comprised of said processed signal data divided into at least one group of subband signal sections interjected where interference has been detected and switchably replaced.
