><title>What is DVB?</title>
><body>
>
><p>
><e>DVB</e> stands for <e>Digital Video Broadcasting</e>. DVB describes methods
>to transfer digital data of TV, radio, interactive services like MHP, EPG and
>teletext. Through data compression with MPEG-2, or H.264 for HDTV, it's possible
>to transfer several channels on the same frequency. The more data compression,
>the more channels can be transfered, but you pay it with quality loss.
></p>
>
><p>
>DVB can be transfered in several ways. The trailing letter identifies the way
>of transfer, e.g. DVB-<e>T</e> for terrestrial transmission. There are some more:
></p>
>
><ul>
>  <li>DVB-S for transmission over satelites</li>
>  <li>DVB-C for transmission over cable</li>
>  <li>DVB-H for transmission to mobile devices (terrestrial)</li>
>  <li>DVB-IPI for transmission over IP based networks, e.g. internet</li>
>  <li>
>    DVB-RC(S/C/T) return channel for the transmission of data services, e.g.
>    broadband internet
>  </li>
></ul>

><title>Types and requirement of DVB cards</title>
><body>
>
><p>
>Beside the different methods to receive the DVB stream, the cards are classified
>by their type of produced output. They're cards with a decoder implemented, which
>offer direct access to the stream by the device <path>/dev/video</path>. These
>cards are called <e>Full featured cards</e>. Other cards havn't an own decoder
>implemented and require a software decoder on the computer and are called
><e>Budget cards</e>. That implies a higher system requirement; you shouldn't use
>a computer based on a CPU with lower than 600 MHz and a memory amount lower than
>256 MB. <uri link="http://linuxtv.org/wiki/index.php/DVB_Card_Vendors">This list
></uri> is useful to identify your

>At first we have to ensure that your kernel supports DVB and your DVB device.
>Since kernel version 2.6 the neccassary drivers are included. Check your kernel
>configuration and make sure the following options are selected as static driver,
>or as module.

></pre>

><p>
>Additionally we have to select the proper driver for your hardware. To find out
>the right module for your card, we mark every driver as module. If you have a

>drivers or you don't own a PCI card, skip this point and continue with <uri

>executing program (e.g. MPlayer loads the file <path>~/.mplayer/lircrc</path>).
