Abstract:
1. A method of binary allocation in an improvement coding or decoding for enhancing a hierarchical coding or decoding of digital audio signals, the method comprising: a core coding or decoding of the digital audio signals in a first frequency band by a core coder or decoder device; and a band extension coding or decoding of the digital audio signals in a second frequency band by a band extension coder or decoder device, wherein, for a predetermined number of bits to be allocated for the improvement coding or decoding, a first number of bits is allocated to a correcting coding or decoding for improving the core coding or decoding in the first frequency band and according to a first mode of coding or decoding and a second number of bits is allocated to the band extension coding or decoding for improving the band extension coding or decoding in the second frequency band and according to a second mode of coding or decoding.
