Using w_scan Scan Files

w_scan is an external utility, not supplied with TVHeadEnd (TVH), that can scan for all available muxes and services. If the default scan files provided with TVH are unable to locate the muxes or services that a user expects to see in their location, the output from w_scan can also be used as a scan file for TVH.

Example

The following command can be used to create a scan file called au-wscan: w_scan -f t -c AU -x > au-wscan The explanation of every w_scan parameter is beyond the scope of this document, however, the -f t parameter is for scanning DVB-T, the -c AU parameter sets to country to Australia and the -x parameter is required to produce the output format required by TVH. Use w_scan -h and w_scan -H for a full list of parameters.

This file can be copied to the scan file location and once TVH has been restarted, used to scan for services.

Depending upon the exact installation of TVH, scan file can be found in various locations: /usr/local/share/tvheadend/data/dvb-scan/ /usr/share/tvheadend/data/dvb-scan/

Please Note: depending upon the parameters used, w_scan can take a very long time to perform a scan.
