w_scan >>> Deutsche Version

w_scan is a small command line utility used to perform frequency scans for DVB and ATSC transmissions.
It is capable of creating channels.conf files (in different output formats !) as well as initial tuning data for scan.
It's based on the utility scan from linuxtv-dvb-apps, but meanwhile it was heavily changed and has different features:

  1. no need for "initial transponders", and such no need for a config file
  2. w_scan finds automatically the best matching dvb card
  3. complete different command line options
  4. a different default output format as well as bunch of output formats. (if you feel, that some format is missing - contact me)

  10. create DVB-T initial-tuning-data:
    w_scan -ft -c DE -x > initial-tuning-data.txt
  11. create DVB-C initial-tuning-data:
    w_scan -fc -c DE -x > initial-tuning-data.txt
  12. create DVB-S initial-tuning-data:
    w_scan -fs -s S19E2 -x > initial-tuning-data.txt
  13. DVB-T kaffeine channels.dvb:
    w_scan -k > channels.dvb
  14. DVB-C kaffeine channels.dvb:
    w_scan -fc -k > channels.dvb
  15. north-american ATSC Aerial (VSB):
    w_scan -fa > channels.conf
  16. north-american ATSC Cable TV (US QAM Annex-B):
    w_scan -A2 > channels.conf
  17. north-american ATSC Aerial (VSB) and Cable (US QAM-B):

Reporting problems:

A log file can be created with

./w_scan  -v -v 2>&1 | tee w_scan.log
usually one can understand from that file what goes wrong.

w_scan start script:

Start with: 

./w_scan_start.sh
