<h2>Introduction</h2> |
| 20 |
|
| 21 |
<p>
|
| 22 |
The idea behind dvbd is to make maximum use of your DVB card by |
| 23 |
allowing multiple channels on the same frequency to be tuned. It is |
| 24 |
split into a daemon (dvbd) and client programs (dvbclient, dvblist). |
| 25 |
It is possible to associate a priority with a connection to the |
| 26 |
daemon, so that (depending on the given priority) the tuner can be |
| 27 |
made available by dropping connections of inferior priority. |
| 28 |
</p>
|

<a href="http://sourceforge.net">SourceForge</a> are kindly hosting |
| 32 |
this project. Here are the important links: |

</ul>

|
| 40 |
<p>
|
| 41 |
NB, at the moment only DVB-T is supported (that's the type of DVB that |
| 42 |
I have), but it should be fairly easy to add support for DVB-S and |
| 43 |
DVB-C. |
| 44 |
</p>
|
| 45 |
|
| 46 |
<h2>Configuration</h2> |
| 47 |
|
| 48 |
<p>
|
| 49 |
The daemon has a configuration file which by default is |
| 50 |
/etc/dvbd/config. The format of the file is lines of key=value. Line |
| 51 |
comments can be begun with #. |
| 52 |
</p>
|
| 53 |
|
| 54 |
<p>
|
| 55 |
The following configuration fields are available: |
| 56 |
|
| 57 |
<dl>
|
| 58 |
<dt>socket</dt> |
| 59 |
<dd>the (unix) socket to listen on. Default is /var/run/dvbd/dvbd.socket </dd> |
| 60 |
|
| 61 |
<dt>pid</dt> |
| 62 |
<dd>the pid file to write to once it has become a daemon. Default is /var/run/dvbd/dvbd.pid </dd> |
| 63 |
|
| 64 |
<dt>log</dt> |
| 65 |
<dd>the log file to write to. Default is /var/log/dvbd.log</dd> |
| 66 |
|
| 67 |
<dt>schedule</dt> |
| 68 |
<dd>the schedule file to write to. Default is /var/spool/dvbd/schedule</dd> |
| 69 |
|
| 70 |
<dt>debug</dt> |
| 71 |
<dd>the debug level (default is 0) If a higher debug level is set, dvbd will not go into the
|
| 72 |
background.</dd>
|
| 73 |
|
| 74 |
<dt>numcards</dt> |
| 75 |
<dd>the number of DVB cards your system supports</dd> |
| 76 |
|
| 77 |
<dt>card0</dt> |
| 78 |
<dd> the first DVB card. The format of this field is type:frontend:channels Where
|
| 79 |
<ul>
|
| 80 |
<li>type may be one of dvb-t, dvb-s or dvb-t.</li> |
| 81 |
<li>frontend is the path to the frontend (tuner) for the card</li> |
| 82 |
<li>channels is the path to the tzap/szap/czap format channels.conf file for the card.</li> |
| 83 |
</ul>
|
| 84 |
If no cards are specified, a default of one dvb-t card is assumed with |
| 85 |
channels file /etc/tzap.channels.conf and frontend |
| 86 |
/dev/dvb/adapter0/frontend0 |
| 87 |
</dd>
|
| 88 |
</dl>
|

<h2>Client Programs</h2> |
| 93 |
|
| 94 |
<p>
|
| 95 |
At the moment there are three client programs. dvbcat, dvblist and dvbsched. |
| 96 |
dvbcat can be used to extract a stream from the dvbd for live TV. |
| 97 |
</p>
|
| 98 |
|
| 99 |
<p>
|
| 100 |
For example: |
| 101 |
</p>
|
| 102 |
|
| 103 |
<pre>
|
| 104 |
dvbcat dvb-t "BBC ONE" | mplayer - |
| 105 |
</pre>
|
| 106 |
|
| 107 |
<p>
|
| 108 |
dvbsched is used to schedule a recording. Note that an output file |
| 109 |
must be specified whose containing directory must be owned by the user |
| 110 |
issuing the request. The directory must also be writable by the dvbd |
| 111 |
program. |
| 112 |
</p>
|
| 113 |
|
| 114 |
<p>
|
| 115 |
The time format is in at(1) format. See at's manpage for more |
| 116 |
information about it. |
| 117 |
</p>
|
| 118 |
|
| 119 |
<p>
|
| 120 |
For example: |
| 121 |
</p>
|
| 122 |
|
| 123 |
<pre>
|
| 124 |
mkdir /tmp/recordings |
| 125 |
dvbsched dvb-t "ITV 2" 19.20 32 /tmp/recordings/itv2.mpg |
| 126 |
</pre>
|
| 127 |
|
| 128 |
<p>
|
| 129 |
If there is a clash the program will ask you if you want |
| 130 |
to cancel your job. |
| 131 |
</p>
|
| 132 |
|
| 133 |
<p>
|
| 134 |
dvblist shows the channels available to tune at the given |
| 135 |
priority (default is 10). |
| 136 |
</p>
|
| 137 |
|
| 138 |
<p>
|
| 139 |
For example: |
| 140 |
</p>
|
| 141 |
|
| 142 |
<pre>
|
| 143 |
dvblist dvb-t |
| 144 |
</pre>
|
| 145 |
|
| 146 |
<p>
|
| 147 |
If there are some existing connections the list of channels |
| 148 |
may be shorter than the full list. |
