# Miscellaneous DVB Notes

## How to test that a device is working?

Here is one basic way to test a [[!template id=man name="dtv" section="4"]]
device. The example uses DVB-T. First install the necessary packages

	# cd /usr/pkgsrc/multimedia/dvb-apps
	# make install package clean

	# cd /usr/pkgsrc/multimedia/mplayer
	# make install package clean

Scan a basic `channels.conf`:

	$ scan -x 0 /usr/pkg/share/dvb/dvb-t/fi-Turku > \
		~/.mplayer/channels.conf

Then you should be able to already use `mplayer`:

	$ mplayer dvb://"YLE TV1"

For more involved testing, one can use for instance `tzap` (or equivalently,
`czap` or `szap`). In one terminal set the driver for recording:

	$ tzap -r "YLE TV1"

This gives continous information such as the signal strength. Check that the
FE_HAS_LOCK flag is present. Then pipe in an another terminal:

	$ cat /dev/dvb/adapter0/dvr0 > file.ts

At some point break and try to play the output file with `mplayer`.
