Claim 3:
4. The method of claim 1, wherein based on a quantity of predictors in the predictor list being equal to 3:
reconstructing the first residual value comprises calculating:

res1=sign(res1′)*(|res1′|>>1), where res1 is the first residual value and res1′ is the first jointly coded value;
reconstructing the second residual value comprises calculating:

res2=(|res1′|&1>0)?sign(res2′)*(|res2′|>>1):res2′, where res2 is the second residual value and res2′ is the second jointly coded value; and
determining the predictor index comprises calculating:

sigIndex=(|res1′|&1))+((|res1′|&1>0)?(|res2′|&1):0), where sigIndex is the predictor index, res1′ is the first jointly coded value, and res2′ is the second jointly coded value.
