Telestar Digibit Twin SAT/IP (solved!)

Post by jksj »

Attempting to get a this SAT/IP box working with master Mythtv. v32-Pre-1660-g3a243d67f1
Setup detects the device fine but there is no way to configure the LNB.
The setup utility that comes with the box does not support this either but it is connected to a normal Sky type LNB so there should not be an issue.
Only the second of the two inputs worked and packets were being dropped so I am returning the device which is a shame because it is a well packaged nice little device.
The addressing might have been wrong as the box shows sat connections 1 and 2 and setup recognises 0 and 1 which might explain why only one input worked but the dropped packets caused noticeable glitching which would drive me crazy. Note it was connected to an Intel NUC through Gbit Ethernet on a local switch.
So in setup only the second input would scan and in normal live tv only the second input worked.
Lots of protocol errors and dropped packets but the two issues may be linked if the inputs are not being addressed correctly.

Re: Telestar Digibit Twin SAT/IP

Post by kmdewaal »

Sorry that it does not work right out of the box... It is more likely that this is a MythTV software issue than a broken box but to be explicit, there is no guarantee that native SatIP support will ever work correct with your box.

A few notes, maybe this gives you some ideas.

0. UPnP device detection looks OK.
1. There is support in MythTV for SatIP boxes using the External Recorder, as described in the Wiki in https://www.mythtv.org/wiki/SAT2IP_play ... ture_cards. If this work your box is OK.
2. The box I have can be configured with a web interface, using the IP address from the mythtv-setup log. In your case 192.168.0.41. I have never used a configuration utility.
3. With the web interface of my box the LNB configuration is done. For me the default did work. All LNBs must be equal. MythTV does not do anything with the LNB setting, that is completely in the box. The numbers as specified on my box count from 1 to 4, the "fe=x" parameter counts also from 1 to 4 but the numbers as reported in the"SatIP: Found..." messages count from 0 to 3. All numbers in MythTV go from 0 to 3.
5. The "Invalid RTCP packet" messages from your first log fragment should never be there.
6. The "Sequence Number mismatch" messages occur after a channel change, this does give a discontinuity in the sequence. In normal operation these message do come only when the MythTV system cannot keep up with the flow of packets. This happens here when I do tests on my lowest-power machine, a RPi3B, but even the RPI3B can do a successful channel scan. With my normal development box (Intel i7) does not have this problem. I expect your Intel NUC to be fast enough.
7. The "DiSEqCDevTree: No device tree" should not be there. This looks like a software bug but I need to figure out which configuration triggers this. It should only happen with real /dev/dvb/.... DVB-S/S2 devices that do not have the LNB configured, not with SatIP. I have not seen it here.
8. The "V4L2" message are harmless and need to be fixed one of these days....
9. I have, via the web interface of the box, done channel scans to check if the box did work. This is needed if you want to use the "External recorder" option but it should not make any difference if you use the SatIP native interface.

Hope this helps,
Klaas.

Thanks for the response.
By configuration utility I meant the web interface.
This device is really simple it does not have the Network and m3ulist items on the 'System' menu that the Digibit B1 does (looking at the latter's manual)
So it looks like its got to be returned.
The device did successfully scan on the second input using mythtv-setup.
So even if you can fix the interface the dropped packets implies that my configuration just cant keep up, so its looking like this solution is unsuitable for me.

Had second thoughts - the potential to get rid of some wiring spaghetti was just too great so. Sent it back and exchanged it for the Digibit R1 quad recever a much better device that works out of the box with master v32-Pre-1707-gf328b56be9.
Still some minor issues whicjh I will start a new thread on.

As far as the Digibit Twin goes its known to work in TV Headend but I think that has been changed to cope with a minor divergence from the SAT/IP standard. The quad device has far more facilities, its worth the extra.
