Classification: CPC G  H | IPC H

Claim 15:
16. The device of claim 14, wherein, based on a quantity of predictors in the predictor list being equal to 4:
the one or more processors are configured to, as part of reconstructing the first residual value, calculate:

res1=sign(res1′)*(|res1′|>>1), where res1 is the first residual value and res1′ is the first jointly coded value;
the one or more processors are configured to, as part of reconstructing the second residual value, calculate:

res2=sign(res2′)*(|res2′|>>1), where res2 is the second residual value and res2′ is the second jointly coded value; and
the one or more processors are configured to, as part of determining the predictor index, calculate:

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