Why is this so complex?

Added by Tiago Silva about 8 years ago

It's probably a stupid and newbie question, but i'm struggling to understand how can my crappy old crt tv, tune every channel available with a simple scan, and i'm here struggling with trying to guess parameters for muxes? Can't this be easier?

Ok, so i ran one of those frequencies:

f = 240500000
sr = 6000000
constelation = QAM/256

and BAM! Finally i saw other muxes being added, i mapped all services found and headed to the interface, but all the channels that were found seem to be the ones i don't have access to, premium channels, or HD versions of the ones i do, and i've tried to play the channels and although tvheadend client gets the schedule of the channel, i can't see nothing.. is there any clue in the output?

Thank you so much for even this small progress

This shows that i should find at 714 Mhz, a Symbol Rate of 6875 (6975000 ?) and a Modulation/Constelation of QAM-64.

But i get NOTHING :(, i borrowed another tv tunner even, an eye-tv hibrid, and got the same frustrating results.

My crappy old tv is still 1.000x easier, just auto scan and done, unbelievable.

Would you expect to be getting "RTP Alores"?

If so, try

f = 261500000
sr = 6000000
constelation = QAM/256

It's possible that the FTA services have been placed in a different network to the Pay TV ones, hence why it's not added those? w_scan certainly references two different network ID's although they look the same.

Are there any of the services you can see on Windows in the w_scan output?

That is one of the muxes it finds when i add the 1st one. So adding one or another has the same effect, the same muxes get automatically added.
I get 24 muxes in total of which only 8 don't fail here are they:

f: 170500000; sr: 6000000; QAM/256
f: 184500000; sr: 6000000; QAM/128
f: 219500000; sr: 6000000; QAM/256
f: 240500000; sr: 6000000; QAM/256 (the one i initially tried)
f: 247500000; sr: 6000000; QAM/128
f: 254500000; sr: 6000000; QAM/256
f: 261500000; sr: 6000000; QAM/256 (the one you suggested)
f: 714000000; sr: 6875000; QAM/64 (WAIT WHAT? i tried this one yesterday, i don't think this one showed up in my first try )

Yes i'm sure that last one didn't show up when i tried the 1st one because now i see a few more services, and on those new are the unencrypted channels i see on windows :D And IT WORKED :D wow, it finally did.

Thank you so much.
