The LinuxTV dvb-apps package contains some Linux DVB API applications and a set of utilities that both the developer and end user alike will find quite useful. Specifically, the utilities are geared towards the initial setup, testing, and operation of a DVB device, whether it be of the sofware decoding (aka budget) or hardware decoding (aka premium or full featured) class.

Obtaining the dvb-apps package

Unfortunately, an element of confusion in regards to the package has been introduced by the fact that not all Linux distributions ('distro's') refer to it by the "dvb-apps" name. The Debian package name, for example, is "dvb-utils". Additionally, you may sometimes also see it called "dvbtools" (though dvbtools is/was itself the name of another set of utilities seperate from the LinuxTV project (see here)).

In any regards, the sources for the dvb-apps package are available for direct download from the LinuxTV website, in either tar.bz2 or tar.gz format. (Note: The build procedure is very simple -- uncompress the download; in a command shell, cd to the top directory level of the uncompressed sources; run 'make' and then 'sudo make install').

Alternatively, if the package is maintained in a repository available for your "distro", then you can obtain it with your package manager. For example:

To install it on a debian system:

 # apt-get install dvb-utils

With gentoo:

 # emerge linuxtv-dvb-apps

Using Fedora, assume root privileges then install the dvb utilities with:

  # yum install dvb-apps
