INFORMATION SIGNAL ENCODING |
摘要 |
Extremely coarse quantization beyond the degree established by the masking threshold with little loss of quality or none at all is made possible by quantizing not the prefiltered prediction or forecast directly, but by quantizing instead a prediction error obtained by a forward-adaptive prediction or forecast of the prefiltered signal. Due to the forward adaptivity, the quantization error has no negative impact on the decoder prediction.
