ADAPTIVE GROUPING OF PARAMETRES FOR IMPROVED EFFICIENCY OF CODING Russian patent published in 2009 - IPC H03M7/40 

FIELD: physics, computer engineering.

SUBSTANCE: invention is related to coding of parametres without losses, and in particular to generation and usage of coding rule for efficient compression of parametres. The present invention is based on conclusion that parametres including the first set of parameters of initial signal first part representation and including the second set of parametres of initial signal second part representation, may be efficiently coded, when parametres are arranged in the first sequence of tuples and the second sequence of tuples, besides the first sequence of tuples comprises tuples of parametres having two parametres from single part of initial signal, and moreover, the second sequence of tuples comprises tuples of parametres having one parametre from the first part and one parametre from the second part of initial signal. Efficient coding may be achieved with the help of bit estimation unit in order to assess required number of bits to code the first and second sequence of tuples, besides only sequence of tuples is coded, which results in reduced number of bits.

EFFECT: improved accuracy of coding.
