Nejjednodušší je mrknout se na seznam podporovaných DVB-T USB zařízení na DVB-T USB Devices a najít některé, které se dá snadno koupit. Následující text popisuje zkušenosti s Leadtek WinFast DTV Dongle Gold (682 Kč).

Podporu v jádře má, stačí nahrát firmware:

[[email protected] ~]# cd /lib/firmware/
[[email protected] ~]# wget http://www.otit.fi/~crope/v4l-dvb/af9015/af9015_firmware_cutter/firmware_files/4.95.0/dvb-usb-af9015.fw

Po připojení tuneru k PC dmesg šťastně hlásí:

Pokud váš dmesg tak šťastný není, nahrajte příslušný modul do jádra

[[email protected] ~]# modprobe /lib/modules/3.1.5-1.fc16.x86_64/kernel/drivers/media/dvb/dvb-usb/dvb-usb-af9015.ko

nebo restartujte PC.

Sledování

A něčím se dívat. Například VLC. Nejdřív repozitáře:

[[email protected] ~]# yum localinstall --nogpgcheck -y http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm -y

A samotné VLC:

[[email protected] ~]# yum install vlc -y

A zábava začíná:

[[email protected] ~]$ vlc channels.conf

Nahrávání

Ještě připomenu, že až si budete chtít něco nahrát, stačí ve VLC ve View zatrhnout Advanced Controls. Na dolní liště přibude tlačítko pro nahrávání. Výsledný .ts soubor najdete v /home/franta_uzivatel/Downloads.
