dvb-apps is a distribution of tools useful for low-level testing and configuration of DVB hardware. In various places it is also called dvbutils or dvbtools. Many consider these tools essential to anyone with a DVB adapter.
Most Linux distributions have a dvbutils package which will be a breeze to install. For example, with Debian or Ubuntu install the package with:
apt-get install dvb-utils
apt-get install dvb-apps
If you have a system based on atrpms.net you can install the utilities with:
yum install linuxtv-dvb-apps
Note: Fedora 12 has dvb-apps and w_scan in the updates repo.
Alternatively, you can build them yourself from the source code. There are two ways of obtaining the sourcecode:
Option 1: Obtain the source code from CVS:
cvs -d :pserver:firstname.lastname@example.org:/cvs/linuxtv login (use an empty password) cvs -z3 -d :pserver:email@example.com:/cvs/linuxtv co dvb-apps
Option 2: Obtain the source code by downloading it:
- Pick the most up to date version from http://linuxtv.org/downloads
- Unpack it using tar xvjf linuxtv-dvb-apps<your version>.tar.bz2
Once you have the source code (and are in the correct directory), build and install it by typing:
make make install
(dvb)scan(dvb)scan is on some systems called "dvbscan" and on others called "scan", it is used to produce a channel configuration file. This is the first step to any successful DVB setup. You use it like this:
scan /usr/share/doc/dvb-utils//examples/scan/dvb-t/au-sydney_north_shore -o zap | tee ~/.mplayer/channels.confwhich gives you a file that mplayer can use (e.g. mplayer dvb:// -vo null)
*zaptzap (and it's siblings szap, czap, & azap) is a command line channel changing and signal monitor program. It can also set your card device up for recording. This util is the most basic means of testing your card. e.g.:
tzap -c ~/.mplayer/channels.conf ABC1
dvbdate is a utility for working with the time signal from DVB transmissions. You can view the transmitted date/time and set the system clock. This looks to be a useful alternative to setting up NTP.
This utility resets Hauppauge DEC USB DVB adapters.
This util appears to create a new network adapter based on the /dev/dvb/adapterN/net0 device.
This appears to analyze dvb traffic, but only on /dev/dvb/adapter0 as it's hardcoded!
This util is used to load the remote control configuration on certain DVB units.
This util gathers signal statistics from dib3000 modulators.
