Claim 19:
20. A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, direct the at least one processor to perform a method, the method comprising:
receiving at least two contexts including a first context and a second context;
for each of the at least two contexts,
obtaining, from at least one lookup table, at least one coding parameter corresponding to the context;
determining a probability interval value corresponding to the context based on a previous probability interval value and the at least one coding parameter;
determining a normalized probability interval value corresponding to the context by performing a normalization operation on the probability interval value;
determining a probability interval lower limit corresponding to the context based on a previous probability interval lower limit and the at least one coding parameter;
determining a normalized probability interval lower limit corresponding to the context by at least performing the normalization operation on the probability interval lower limit; and
outputting at least one byte corresponding to the context based on the normalized probability interval lower limit.
