Description

Dear Developers!

I am using tvheadend for a long time now. New technologies come into play for the Sattelite market.
http://www.inverto.tv/products/product.php?section=3&id=329

These programmable unicable lnbs will become more usual in future. It can staticaly "mount" transponders into
the cabletree of an house installation. In my case the frequencies to tunein a transponder are completely different then
from those of the satalite itself by using a legacy lnb for example. In Result of this behavior a "Network discovery"
does not make sense anymore in its current state.

--------------------------------------------------------------------------------
Examples:
http://www.hdtv-sender.com/hd-sender/3sat-hd/
Channel:3 Sat HD
original Transponder: 11347V
in my case: 11005V

http://www.br.de/unternehmen/inhalt/technik/hd-br-digital100.html
channel: BR Fernsehen Nord HD
original Transponder: 11582V
in my case: 11208V
--------------------------------------------------------------------------------

What i did is a "blind scan" with my LG tv and picked out the transponders(32-lnblimit), which the lnb staticaly provides, one by one into tvheadend. This Method worked verry well
but took me hours to complete cause you have to pick every value by hand (freq,symb,roll....).

I tried Network discovery over few days, because i made good experiences over the years within other installations. But it is screwing you up all the time on such static lnb installations.
Playback is stuttering, a lot of channels are missing ~60% and you end up with ~200 dead transponders in your muxes list(Astra 19.2°).

What do you think, is a blindscan feature doable/desireable?

Thanks!
