- 초록
- In [1,2,3], Binaural Cue Coding (BCC) was introduced for multi-channel spatial rendering for MPEG 4 - SAC (Spatial Audio Coding) to reduce bitrate of multi-channel audio signal. In [4,5], Virtual Source Location Information (VSLI) was introduced to replace InterChannel Level Difference, the most determinant parameter in BCC system. Here, Variable Bit Quantization (VBQ) for VSLI is proposed to reduce bitrate at the quantization block in VSLI-based BCC systems removing statistically invalid range. © Springer-Verlag Berlin Heidelberg 2005.
