Abstract:
A method of performing entropy coding of a sequence of symbols, each of said symbols having a numerical value associated therewith, the method comprising the steps of:identifying a first subsequence of said symbols, the first subsequence of said symbols having a first number of symbols included therein, the first number of symbols being based on the numerical values associated with said symbols included in said first subsequence of said symbols and further based on a size of a set of combined symbols; coding the first subsequence of symbols with use of a first combined symbol representative of said first subsequence of symbols and with use of a symbol representative of the first number of symbols, wherein said first combined symbol is a member of said set of combined symbols; identifying a second subsequence of said symbols, the second subsequence of said symbols having a second number of symbols included therein, the second number of symbols being based on the numerical values associated with said symbols included in said second subsequence of said symbols and further based on said size of said set of combined symbols, wherein said second number of symbols differs from said first number of symbols; and coding the second subsequence of symbols with use of a second combined symbol representative of said second subsequence of symbols and with use of a symbol representative of the second number of symbols, wherein said second combined symbol is a member of said set of combined symbols.
