Hi,
Im loosing TS packets in my dual CAM premium TT S-2300 card (av7110+saa7146).
Is it possible the problem is in firmware? Here is the description:
04:00.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
Subsystem: Technotrend Systemtechnik GmbH Technotrend/Hauppauge DVB card rev2.3
Flags: bus master, medium devsel, latency 32, IRQ 20
Memory at fddff000 (32-bit, non-prefetchable) [size=512]
Kernel driver in use: dvb
dvb 0000:04:00.0: PCI INT A - GSI 20 (level, low) - IRQ 20
IRQ 20/: IRQF_DISABLED is not guaranteed on shared IRQs
saa7146: found saa7146 @ mem ffffc90005248000 (revision 1, irq 20) (0x13c2,0x000e).
dvb 0000:04:00.0: firmware: requesting dvb-ttpci-01.fw
DVB: registering new adapter (Technotrend/Hauppauge WinTV Nexus-S rev2.3)
adapter has MAC addr = 00:d0:5c:04:2e:ea
dvb 0000:04:00.0: firmware: requesting av7110/bootcode.bin
dvb-ttpci: info @ card 0: firm f0240009, rtsl b0250018, vid 71010068, app 80f12623
dvb-ttpci: firmware @ card 0 supports CI link layer interface
Ive tried also:
dvb-ttpci: info @ card 1: firm f0240009, rtsl b0250018, vid 71010068, app 8000261a
dvb-ttpci: info @ card 1: firm f0240009, rtsl b0250018, vid 71010068, app 80002622
without any impact.
SR of my signal is 27500, 2x official CAMs (videoguard).
I use dvblast to select 4 TV channels (~ 16 PIDs) from multiplex,
descramble them and stream them to network. Dvblast reports TS
discontinuity across all video PIDs only (no audio) usually every
1-3 minutes ~80 packets. But sometimes it goes well for tens of
minutes (up to 1-2hours). Everything seems to be ok with 3 TV channels.
Do you thing it is av7110 issue? Do you know any relevant limits of
av7110? What should I test/try more? Thanks
The full-featured cards are not able to deliver the full bandwidth of a
transponder. It is a limitaion of the board design, not a firmware or
driver issue.
You can fix this by applying the full-ts hardware modification.
