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

Before using these tools you will need to build them yourself from the source code. To obtain the source code, the best way is to download it 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

Alternatively, download it from http://linuxtv.org/downloads (picking the most uptodate version) and 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 typeing:

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.


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.
