Abstract

MPEG Surround (MPS) defined by ISO/IEC is the audio coding standard of multi-channel signals based on the down-mixed signal and the spatial parameters. In MPEG Surround, the time-frequency tiles decide the units to share the same spatial parameters among the multi-channel signals. Hence, the decision of the tiles is the critical module deciding the required quality and bits. However, the large number of combination in the time regions, frequency bands and multi-channel signal statistics has spanned the huge search space for deciding the tiles. Our previous work in AES 119 has proposed the dynamic programming method to efficiently decide the time-frequency units for the parameter stereo coding in HE-AAC. This paper will extend the dynamic programming method to the MPS coding.
