When I did run scan command using /usr/share/dvb/dvb-t/cz-All table, some
channels that my "ordinary" TV did tune did not tune (even attempt to tune) on
the PC TV adapter. I traced issue to
the aforementioned table, which is (by commented header inside the table)
taken from public sources not directly under the CZ TV regulator's control. I
found the official broadcast spectrum
regulation (as of August 2012 - currently valid) here
http://www.ctu.cz/cs/download/plan-vyuziti-radioveho-spektra/rok_2012/pv-
p_10-08_2012-11.pdf
It states on pages 9, 15-16 that all the channels 21-60 are allocated for
various DVB-T networks in the country. The aforementioned table cz-All did
include just some of them, what lead to
"missing" of some newly installed channels from the scanning. (Understandable,
DVB-T is still in the development phase in Czech republic and many spectrum
allocations are still designated as
testing or not-definitive.)
Attached is the new table I created, ensuring scan of all the channels
theoretically allocatable in Czech republic. Tested on my own comp it really
found channels consistent with the TV box scan,
with no bugging.
The only part I am not sure about is the guard-interval where 1/4 and 1/8
values were irregularly mixed in the original table and no regulatory
guidelines are released. Based on the theoretical
assumption, that 1/8 should tune (i.e. not exclude) more channels than 1/4, I
entered 1/8 for all the channels. Should you have better experience or
regulatory resources on the topic, please,
correct these values as appropriate.
I suggest to replace the cz-All table with my updated one in the next release.
Thanks for your mail. The scan files have been split out into a
separate package called dtv-scan-tables. Therefore I am reassigning it
to d-s-t. Oliver Schinagl (CC'd) is the upstream dtv-scan-tables
maintainer. I have reattached your cz-All-actual-2013 for his consideration.
Pushed to github, git.linuxtv.org for inclusion.
Oliver
Thanks,
Jon
