VERFAHREN ZUR VERWALTUNG DER TONSIGNALKODIERUNG UND -WIEDERGABE IN EINEM ASYNCHRONEN ÜBERTRAGUNGSSYSTEM |
摘要 |
The invention concerns a method for decoding and retrieving a sound signal in an asynchronous transmission system which consists in detecting an backfilling overload in said buffer memory and/or a second memory in the input or the output of the decoding unit and comparing the backfilling rate to at least a threshold. The invention is characterised in that, depending on the value of the backfilling rate, it consists in using a detection of voice activity and in eliminating the frames considered as being non-active by said detection; carrying out a concatenation processing on two successive frames. |
