Claim 4:
5. The method of claim 1, wherein based on a quantity of predictors in the predictor list being equal to 2:
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=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)), where sigIndex is the predictor index and res1′ is the first jointly coded value.
