Abstract:
The present disclosure provides methods, devices and computer program products for encoding and decoding of a vector of parameters in an audio coding system. The disclosure further relates to a method and apparatus for reconstructing an audio object in an audio decoding system. According to the disclosure, a modulo differential approach for coding and encoding a vector of a non-periodic quantity may improve the coding efficiency and provide encoders and decoders with less memory requirements. Moreover, an efficient method for encoding and decoding a sparse matrix is provided.

Claim (Index 14):
The method of  claim 10 , wherein, for a plurality of frequency bands or a plurality of time frames, the positions of the at least one encoded element form one or more vectors, wherein each position is represented by an entropy coded symbol, wherein each entropy coded symbol in each vector of entropy coded symbols corresponds to one of the plurality of frequency bands or one of the plurality of time frames,\n wherein the method comprises decoding the one or more vectors of entropy coded symbols into one or more vectors of parameters, wherein each vector of entropy coded symbols comprises a first entropy coded symbol and at least one second entropy coded symbol and wherein each vector of parameters comprises a first element and at least one second element, wherein decoding the one or more vectors of entropy coded symbols includes: representing each entropy coded symbol in the vector of entropy coded symbols by a symbol which may take N integer values by using a probability table; associating the first entropy coded symbol with an index value; associating each of the at least one second entropy coded symbol with an index value, the index value of the at least one second entropy coded symbol being calculated by:\n calculating the sum of the index value associated with the of entropy coded symbol preceding the second entropy coded symbol in the vector of entropy coded symbols and the symbol representing the second entropy coded symbol; \n applying modulo N to the sum; \n representing the at least one second element of the vector of parameters by a parameter value corresponding to the index value associated with the at least one second entropy coded symbol.
