Important.png Note: The correct title of this article is dvb-apps. It appears incorrectly here due to technical restrictions.

dvb-apps is a distribution of tools useful for low-level testing and configuration of DVB hardware. Many consider these tools essential to anyone with a DVB adapter.

Getting dvb-apps

The best way to get them is to download them from CVS and build them youself.

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
make install

Alternatively, download them from http://linuxtv.org/downloads, picking the version you want. Unpack the tools using:

tar xvjf linuxtv-dvb-apps<your version>.tar.bz2

Then, go to the directory created when you untared the file and type:


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.


dvbscan is used to produce a channel configuration file. This is the first step to any successful DVB setup.


tzap (and it's siblings szap and czap) 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.


This is a util 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.
