695	prefix of firstGreater1ScanPos	PhuongNguyen	bbross	"Hello,

actually, variable firstGreater1ScanPos is derived as followed :

firstGreater1ScanPos = -1
...
if (coeff_abs_level_greater1_flag[n] && firstGreater1ScanPos == -1)
   firstGreater1ScanPos = n

This means that firstGreater1ScanPos is the first coefficient read from the bitstream having absolute value greater than 1 when we scan from high frequency to low frequency.

The prefix first is used rather for the LAST element in a scan from high frequency to low frequency. This is the case for firstSigScanPos.

I am wondering if we should call it lastGreater1ScanPos instead of 
firstGreater1ScanPos in order to respect the prefix convention in the spec.

Also, could you please point me to a discussion or study on the use of firstGreater1ScanPos?

Best regards,
Phuong Nguyen."	enhancement	closed	minor	D8	Text	D8 (J1003) d7	fixed		bbross wjhan jct-vc@…
