Yes, that's right. It's used in our set-top box(STB).
I just try to do some base firmware tests now. And may be added supports under OpenCT later.
I changed a card and readed out the ATR:
TS: 3f T0: ff TA1:95 TB1:00 TC1: ff TD1: 91 TA2: 81 TD2:71 TA3:a0 TB3:47 TC3:00
History: 44 4e 41 53 50 30 20 54 65 73 74 30 33
So, It should be a nagravision card , and there may be some unknow problems in the former card i used.
But I got a new problem.
The TD1 in the ATR is 0x91, so only protocol T=1 is supported.
And TA1 is 0x95, that means Fi=9, Di=5,not Fd=Dd=1 any more.
And TA2 is 0x81, means that it's Specific mode.and it's bit5=0.
Then whether I needed sending PTS to select protocol T=1 after receiving ATR ?
If needed, how to send it ?
Because "ISO7816 3.4 Protocol type selection (PTS) " said "If only one protocol type and FI=D=1 (default value of TA1) and N smaller than 255 is indicated in the answer to reset. The transmission protocol associated to the protocol type may be started immediately after the transmission of answer to reset. "
So, I can't send PTS because Fi=9 and Di=5, and N=0xff.
If not, the following operations such as SELECT FILE use which F and D(Fi, Di or Fd, Dd) ?
I did'not found clear answers in ISO7916-3 about these things. May be I shoule read it once more.

A ha, You have a good sense of humor. But sometimes it's no choice.
It's so long, thank you for your time.
