Abstract:
1. A method of arithmetic code package outputting, comprising: acquiring a 7-bit output string according to upper bits of a CodLow value, wherein each bit of the 7-bit output string defines an output character, and the CodLow value is a starting position of a probability space to be updated; generating a 7-bit ID string to identify states of the output characters of the 7-bit output string, wherein each state is a confirmed state or an undetermined state; acquiring a first number according to a CodRange value, wherein the CodRange value is a length of the probability space to be updated; extracting the first number of output characters from the 7-bit output string to form valid output characters, identifying the state of each valid output character according to the 7-bit ID string; and processing the valid output characters according to the states of the valid output characters to obtain coding output bytes, and outputting the coding output bytes, wherein the output characters adopt binary representation, with “00” indicating “0”, “10” and “11” indicating “1”, and “01” indicating characters in undetermined state.
