Classification: CPC H | IPC H

Claim 10:
11. The method of claim 10, wherein the identifying the one of the candidate context models for coding the respective bin comprises:
clipping the template magnitude of the respective transform coefficient based on a template magnitude clipping threshold to obtain a clipped template magnitude, denoted by tmplMgCli, according to:

tmplMgCli=min(the first template magnitude, the template magnitude clipping threshold);

determining a subinterval indicator based on the clipped template magnitude according to:

indi=(tmplMgCli+a)>>b, 

where indi represents the subinterval indicator that indicates the first subinterval the template magnitude belongs to, a represents an offset, b represents a shift value, and a and b are non-negative integers; and
identifying the one of candidate context models based on the subinterval indicator for the respective transform coefficient.
