[0022] This chapter uses an actual implementation case to explain the implementation of the algorithm described in the present invention. First agree on the hexadecimal number X 1 =000000,X 2 =000001 and X 3 =000002 is the start code, that is, the start codes are all 24-bit binary strings, and n=3. Then agree on Y 1 =000003, Y 2 =000004 and Y 3 =000005 is the enumeration conflict code. Finally, it is stipulated that m=8 in this implementation case, that is, the matching operation of the binary string takes bytes as the boundary. Thus, for any ,have . for any , X i and Y i same length. and for any Y i , any , Y i the last of bit strings do not constitute any X j prefix. Although n=3 and m=8 are agreed here for the sake of convenience, the present invention is not limited thereto. n can be any small integer greater than or equal to 1, and m can be 1, 2, 4, 8 or 16.
[0023] First, the encoder operation will be described. For any piece of input encoded ...
