Abstract:
For an efficient encoding of subband configuration data the first, penultimate and last subband groups are treated differently than the other subband groups. Further, subband group bandwidth difference values are used in the encoding. The number of subband groups NSB is coded using a fixed number of bits representing NSB−1. The bandwidth value BSB[1] of the first subband group is coded using a unary code representing BSB[1]−1. No bandwidth value BSB[g] is coded for the last subband g=NSB. For subband groups g=2, . . . , NSB−2 bandwidth difference values ΔBSB[g]=BSB[g]−BSB[g−1] are coded using a unary code, and the bandwidth difference value ΔBSB[NSB−1] for subband group g=NSB−1 is coded using a fixed number of bits.
