TONSIGNALKODIERUNG MIT GERINGER VERZÖGERUNG UNTER ALTERNIERENDER VERWENDUNG VON PRÄDIKTIVER KODIERUNG UND TRANSFORMATIONSKODIERUNG |
摘要 |
<p>An encoder and a method for encoding a digital signal are provided. The method includes encoding a preceding frame of samples of the digital signal according to a predictive encoding process, and encoding a current frame of samples of the digital signal according to a transform encoding process. The method is implemented such that a first portion of the current frame is also encoded by predictive encoding that is limited relative to the predictive encoding of the preceding frame by reusing at least one parameter of the predictive encoding of the preceding frame and only encoding the parameters of said first portion of the current frame that are not reused. A decoder and a decoding method are also provided, which correspond to the described encoding method.</p> |
