Hi all,
I just playing with some dvb-s
card, ordered as "Win TV-NOVA CI".
(but based on info on attached cd it
is "TT-budget S-1500")
This card came with CI extension board,
so I want to use it to receiving
some Cryptoworks encrypted programs, in conjunction
with
SCM Cryptoworks adapter a Cryptoworks card.
Kernel is latest 2.6.15.4, latest mercurial, player
is latest
vlc /w dvb support compiled in.
PROBLEM:
...is that pci subid of card (0x017) cause
detect and serve it by "budget"
driver instead "budget-ci", so CI
option is unavailable:
Feb 14 04:08:18 dvbfm kernel: DVB: registering new
adapter (TT-Budget/WinTV-NOVA
-S PCI (rev AL/alps bsbe1 lnbp21 frontend)). Note that all free-to-air programs works with
autoloaded "budget" driver great,
but because I really WANT to use CI on this
card I did these tests:
1) simple move subid 0x017 from budget driver
to budget-ci driver
-> after this change CI was initialized, CAM
detected, but tuner do not get lock.
As I found, tuner BSBE1 which is on card
really presented is not supported
on "budget-ci" (budget-ci coded only for WinTV
with BSRU6 tuner)
2) so next - because card did work with
"budget" driver ok before - I try to copy
also bsbe1/lnbp21 related parts of code
analogically from "budget" to "budget-ci"
(functions like alps_bsbe1_inittab,
alps_bsbe1_set_symbol_rate, alps_bsbe1_pll_set,
lnbp21_set_voltage, lnbp21_enable_high_lnb_voltage,
lnbp21_init)
after this change card seen as budget-ci
card:
Feb 14 15:12:29 dvbfm kernel: saa7146: found saa7146 @ mem df896400 (revision 1, irq 177) (0x13c2,0x1017). Feb 14 15:12:29 dvbfm kernel: DVB: registering new adapter (TT-Budget/WinTV-NOVA -CI PCI). Feb 14 15:12:29 dvbfm kernel: adapter has MAC addr = 00:d0:5c:04:72:a1 Feb 14 15:12:29 dvbfm kernel: input: Budget-CI dvb ir receiver saa7146 (1) as /c lass/input/input4 Feb 14 15:12:29 dvbfm kernel: budget_ci: CI interface initialised Feb 14 15:12:29 dvbfm kernel: DVB: registering frontend 1 (ST STV0299 DVB-S)... Feb 14 15:12:31 dvbfm kernel: dvb_ca adapter 0: DVB CAM detected and initialised successfully RESULT:
FREE programs works still great (like before),
without any errors.
CRYPOTWORKS programs start playing ok too, but
stream seems
to have a some
quality problems:
- sometime errors in picture observed (3-30%
of screen, once per 10-60sec)
but not reported by
input in vlc. On screen it seems like errors in stream,
but signal is ok (all free programs on same transponder works great)
- sometime screen freezes for 5-20 seconds
(once per 1-3 minutes) , vlc
reporting ussualy some changing of rate ended with
new lock of tuner
during this time.
QUESTION:
what cause these errors in receiving of
Cryptoworks programs? some
next changes of code
or configuration recommended? some tips?
it is a last, but
essential problem of my vlc stream,
and I am open to help to assist in test with
my hardware :-)
which is best way to assure that card with subid
0x017 will be in next
releases of kernels detected by right, modified "budget-ci" driver?
(only in case if problem in first question solved
:-) )
Thanks,
Pavel
