Mux found, but no services available

pierre azerty

Hello,

I am setting up a media center based on XBMC and Ubuntu Linux (14.04 alpha and 3.13 kernel)
My DVB adapter is a Pinacle PCTV 73A USB and it works on that box with me-tv.
When using tvheadend (3.4.27~gfbda802~raring), the adapter is recognized as DiBcom 7000 PC and the initial scan finds 40 muxes, that appears in the Muxes tab.

Unfortunately, there are not any services found.

Googling did not help... will you ? :)

hugh thomson

bump.

I got the similar situation. it comes up as DiBcom 7000 PC, I add muxes manually using info from http://www.ukfree.tv/transmitters.php but it doesn't seem to give the muxes a muxid, network id, or find any services. It will show x muxes awaiting initial scan and the map dvb services to channels is greyed out. I have it installed on opnelec.

I have had this tuner for years and have had it working in the past fine. I am in the UK (angus transmitter) and always have to add the mux manually but I think this is normal.

I have tried deleting muxes, restarting, varying the mux info, playing with the tick boxes on the general tab. hopefully someone can assist us somehow on this.

Many Thanks,

Hugh

Can you both provide a screenshot of your muxes, please, as well as a link to what you think you should have (I think Hugh's reference to Angus is probably good enough for me to find them). It may be that you have the mux information incomplete, and something's missing that's needed to make sense of the signal.

I've got the DiBcom chipset in one of my tuners, and it works fine.

@pierre - it may be that you're auto-scanning and picking up the analogue channels, not the digital muxes - or that the mux records are out of date (a common issue) and things have moved around. You need a good source that will tell you what the mux frequencies are and how they're configured.

@Hugh - try adding the frequencies as listed on ukfree.tv, but make sure the frequency is correctly in kHz and the bandwidth is 8kHz. The rest of the fields can be left as Auto.

Hello,

Thank you for taking care of this problem.

Here is a screenshot of the muxes.

I live in France and as long as I know, there is no more analog TV broadcasted.

As I successfully use both me-tv and Kaffeine, is there a way to get the channels from some file ?

hugh thomson

Hi Yaffle,

Thank you for the quick response. I have attached the screenshots to the message all being well. Below is the full story I think:

Hardware: 5 yr old version of http://www.asrock.com/nettop/overview.asp?Model=ION%20330 I bought in 2008 along with my hauppage tv tuner.

I live in Perth, Scotland.

I've had it working with tvheadend on linux mint OS from about version 12 to version 14. I did fresh instal of linux 16 a few weeks ago along with latest version of tcheadend. I had the same issue as shown in screenshots. I then installed a version of openelec http://openelec.tv/ booting from a flash drive which comes preinstalled with tvheadend. I had the same issue.

I have double checked I am getting a signal on the coaxial cable by connecting direct to tv.

There was a guide in the web that gave specific settings for all the muxs settings for the UK so I tried them before reverting back to using "auto" for everything I could. I have tried playing with the check boxes on the general page. I have rebooted etc. It doenst do anything when I add muxes and the log file doesnt show anything.

Any help with this would be greatly appreciated. Our freeview dvr box broke the other day and I would like to finally move over completely to tvheadend & openelec and save the purchase of another av box.

Many Thanks,

Hugh

ProfYaffle

Immediate obvious thing for Hugh - your adapter isn't enabled! Try switching it on with the "Enable" tick box. I'll take a look to see if there's anything else obvious.

Pierre - do you have a source that lists what muxes/configurations you should get where you live? The QAM64/8MHz/8kHz looks right for what I know of French DVB-T, so I'd suspect the frequencies. Also, can I see your adapter config, please, to see if there's anything obvious there.

ProfYaffle

Additional thought... you both have too many muxes, I think.

There are 8 muxes in Dundee, not all of which are broadcasting yet - and this includes the DVB-T2 (HD) ones, which this chipset won't receive. So to have 11 is excessive - it won't break anything, it's just baggage. Also, turn on idle scanning so you can find any muxes we miss.

I have to also doubt thatTrifouillis-les-Oies has 40-odd muxes as well, so I'm suspicious of this list.

pierre azerty

I do agree that 40 muxes are too much. I should have 8 muxes

Prof Yaffle,

Doh!...I could have sworn I had that enabled originally. Dont know how I managed to miss that. I enabled it and the services were found and mapped. As attached.

It only picked up a small number of channels but I think this is just due to the rubbish tv aerial but moving house in a couple months so that will hopefully fix the issue.

thanks so much for your help. embarrassed to miss the simple mistake but its good to get an easy fix.

Many Thanks,

Hugh

ProfYaffle

Hmmm... still not sure of those muxes, Hugh, but I'll live with it. I suspect you're not actually pointing at the Dundee transmitter you linked to, but if it works then who am I to argue! Glad you have something.

One down...

@Pierre: your config looks okay, but the fact that you have 30 muxes awaiting scan doesn't help. I'd suggest you delete all of your muxes and start again. You need just the 8 you list, so let's aim for that for the moment.

I'm guessing at this point, but... assuming your 8 muxes are at the same frequency on both side of La Manche... and that's a big assumption...

R3: 33H 11W = Les plages en clair de CANAL+ , C+ SPORT (avec tuner HD MPEG-4) + les chaînes payantes C+ CINEMA et PLANETE+ (TOWERCAST).

Presuming 33H == channel 33 == 570MHz, that means you'd have these frequencies:

R3: 33H = 570MHz
R2: 36H = 594MHz
R6: 42H = 642
R4: 47H = 682
R5: 48H = 690
R8: 51H = 714
R1: 54H = 738

R7: 57H = 762

Soooo... try re-adding these, QAM64, 8MHz bandwidth, Auto everything else, and see what we get.

If you've got anything more specific, though, that would be good: the precise transmitters local to you, with channels/frequencies per mux.

Removing muxes and adding them manually lead to success !

I think that will be ok now.

I still have to read the manual to figure out how to watch the channels to make sure it is really ok, but I am confident.

I attach 2 screenshots to show muxes and channels

Thank you for your help

ProfYaffle

Excellent - glad it's all working. You've got the services and the channels, so I'm sure it will work. I'm a little suspicious of the mux at 4.3GHz, but that's disabled so I'll let it go...!

Good luck.

Brad Jones

Prof yaffle I'm having similar problems I'm trying to set up ota signal and I get 0 services I've been reading everywhere and it leads me to you can u help me please

Brad Jones

There's a screenshot for u

ProfYaffle

@Brad - can you help me understand a little more about your setup, please - where are you, how are you adding the muxes initially, what's your platform, etc.?

From the screenshot, it looks like it's scanning the muxes but getting stuck on something - I don't immediately know why, though. Does it stay on 281 muxes, 262 to scan, currently tuned to 689,000?

Plus... this is terrestrial, yes? With 281 muxes +/- the 689MHz range? Google suggests it's ATSC, but I'm not sure that explains the number of channels (carrier frequencies) you're seeing.

Other things I turned up - if this is on a Pi, you may have power issues... and if this is a hybrid tuner, there are some reports of w_scan working but tvheadend not, because of the analog(ue) side of the house. See the last post on this thread:

http://www.raspberrypi.org/phpBB3/viewtopic.php?f=38&t=22293

(post by Inept-Get » Mon Nov 25, 2013 8:53 pm)

I'd suggest you play a bit with w_scan to see if the stick itself is okay. After that, we can move to tvheadend - it seems common that it doesn't play nicely with ATSC, but that's simply because no-one on this side of the Atlantic can test it.
<<

ProfYaffle

EDIT

Still guessing at location/technology, but have look at this as well. It's for HDHomeRun, but maybe there're some diagnostic pointers in there since it has to address the ATSC issue.

@ Prof
Running raspmc I'm in Chicago, IL USA. The USB tuner is hauppauge wintv-hvr 950q. I'm running all USB devices through a powered hub Gigaware 4 port USB 2.0 desktop hub. I can send you a screen shot of my dmesg of the raspberry pi. Also I'm a complete noob at all this tv stuff I'm usually into windows, Mac , and dabble in Linux a lil just for stream lined media centers.
Ok so at first I wasn't sure what set of muxes to add so I just added a several more after I kept sawing no services. Illhave to go back and check again to see what I'm tuned to and what muxes I have and what I have left to scan. I'm gonna do more reading and investigating and I'll get back thanks so much

ProfYaffle

My guess, then - and I stress that it's really just that! - is that you've got some duff muxes defined. They may be valid carrier frequencies where you are (e.g. if there are old analogue channels still broadcasting), or they could be vacant - but, either way, tvheadend is getting stuck trying to find services on something that isn't actually carrying a multiplexed signal.

Take it back to basics and figure out what you need where you are (adapting for the 8ft of snow, which will surely reflect all those Canadian channels about how to be terribly polite at all times :-) ), and add just those as a minimal set. You have "autodetect muxes" on, so it should find anything you've missed... indeed, if all else fails, you may be able to get away with adding just one known-good frequency (a regular TV will tell you somehow) and let tvheadend find the rest over some random interval.

Brad Jones

I had to walk away from it for a day I was getting so frustrated. Let me ask you a couple things. How long should it take to scan the muxes? If I selected extra muxes like cable ones with the intended atsc would that effect me? And how can I erase all the muxes waiting to be scanned to start over again and just select the USA atsc ? Would all that even help? Since I'm not supper good at command line I don't know how to capture the log from dmesg to show u every time is right click and drag and highlight so I can copy the text the damn the enters it in the command line like I, giving it a huge command I did that 2x it did something to it but what I dunno that's another issue. Thanks

Brad Jones

Ok so I just know figured out what I were talking about with w_scan since I'm an idiot with command will you help explain in laymans terms what that person did. Like step 1 ....... 2.... Do u enter in all # seems like an awful lot. God I know your thinking I'm awful dumb. I swear I'd be in your debt thanks, brad
