This is a little channel scan utility to generate szap/tzap/czap/azap
compatible channel lists. An atsc/dvbscan does not do a frequency scan, however,
so you must manually provide the data for tuning to one or more start
transponders. A number of initial-tuning-data files are provided for various
dvb-c, dvb-s, dvb-t and atsc networks around the world. If you make a new one
feel free to submit it to the linux-dvb mailing list
http://www.linuxtv.org/lists.php.

Basic usage: dvbscan /usr/share/dvb/dvb-s/Astra-19.2E | tee mychannels.conf
or           atscscan atsc/us-NTSC-center-frequencies-8VSB

If you want it to check a specific frequency, tune to that frequency
(e.g. using szap/tzap/czap/azap) and then use 'dvbscan -c' or 'atscscan -c'.

For more scan options see dvbscan -h or atscscan -h
Tuning files are stored in /usr/share/dvb.

atscscan is _just_ a copy of dvbscan to not confuse ATSC-user.

Good luck,
