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.

Getting dvb-apps

Precompiled

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

or

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

Source

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:anonymous@cvs.linuxtv.org:/cvs/linuxtv login (use an empty password)
cvs -z3 -d :pserver:anonymous@cvs.linuxtv.org:/cvs/linuxtv co dvb-apps

Option 2: Obtain the source code by downloading it:

1. Pick the most up to date version from http://linuxtv.org/downloads
2. 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

The apps

NOTE: Several of these tools may not operate properly while you are running the mythbackend. If mythbackend is running, it may have a lock on your DVB card, denying access to one of these tools.

(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.conf

which gives you a file that mplayer can use (e.g. mplayer dvb:// -vo null)

*zap

tzap (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.

dvbdate

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.

ttusb_dec_reset

This utility resets Hauppauge DEC USB DVB adapters.

dvbnet

This util appears to create a new network adapter based on the /dev/dvb/adapterN/net0 device.

dvbtraffic

This appears to analyze dvb traffic, but only on /dev/dvb/adapter0 as it's hardcoded!

av7110_loadkeys

This util is used to load the remote control configuration on certain DVB units.

dib3000-watch

This util gathers signal statistics from dib3000 modulators.
