Abstract
A method of compressing sorted data representation symbols sequentially. Steps include determining whether a symbol currently being encoded is identical to an immediately preceding symbol; encoding the result as a binary event; if the symbols are identical, encoding the symbol ends; if the symbols are different and there is a constant difference between several previous pairs of symbols, determining whether the difference between the current symbol a and the symbol immediately preceding it b is the same as the difference between the symbol b and the symbol immediately preceding it c, and encoding the determination result as another binary event; in the case of positive result of the latest determination, encoding the symbol ends; otherwise, encoding the symbol using a bitwise operation in which bits of the symbol's binary representation are processed sequentially from the most significant bit to the least significant bit. A corresponding decompression method is provided.
