dvbt-tsid-qual - Show signal quality of DVBT channels
dvbt-tsid-qual [options]
Options:
-debug level set debug level -verbose level set verbosity level -help brief help message -man full documentation -cfg <config> use specified configuration directory -tsid <tsid> show only the specified multiplex
Print a brief help message and exits.
Prints the manual page and exits.
Set verbosity level. Higher values show more information.
Set debug level. Higher levels show more debugging information (only really of any interest to developers!)
Specify an alternate configuration directory (containing the dvb-ts, dvb-pr files) to use, rather than using the default.
Specify the TSID and only the results for that multiplex will be shown
Script that uses the perl Linux::DVB::DVBT package to provide DVB-T adapter functions.
Reads the config files (either default set or specified using the -cfg option) and then records a few seconds for each channel, displaying the results showing any errors.
The displayed channel information contains:
The logical channel number (where supported) or just an incrementing index.
The channel name as broadcast
Whether this is a TV channel (i.e. contains video), or a radio station (audio only)
The statistics column shows the results of recording this channel. It is in two parts: video and audio. Each part contains the number of recorded packets, the number of errors (shown as number e) and the number of buffer overflows (shown as number o)
For example:
2 | Yesterday | tv | video: 5252 ( 0 e 0 o) audio: 436 ( 0 e 0 o)
Once the full set has completed, a summary table showing statistics for each multiplex is shown.
