- * <refsect2>
- * <para>
- * MythTVSrc allows to access a remote MythTV backend streaming Video/Audio server,
- * and to render audio and video content through a TCP/IP connection to a specific
- * port on this server, and based on a known MythTV protocol that is based on
- * some message passing, such as REQUEST_BLOCK on a specified number of bytes, to get
- * some chunk of remote file data.
- * You should pass the information aboute the remote MythTV backend server
- * through the <link linkend="GstMythTVSrc--location">location</link> property.
- * </para>
- * <title>Examples</title>
- * <para>
- * If you want to get the LiveTV content (set channel, TV tuner, RemoteEncoder,
- * Recorder),
- * put the following URI:
- *
- * <programlisting>
- * myth://xxx.xxx.xxx.xxx:6543/livetv?channel=BBC
- * </programlisting>
- *
- * This URI will say to the gmyth library to configure the Recorder instance (used to
- * change the channel, start the TV multimedia content transmition, etc.), using
- * the IP address (xxx.xxx.xxx.xxx) and port number (6543) of the MythTV backend
- * server, and setting the channel name to "BBC".
- *
- * To get a already recorded the MythTV NUV file, put the following URI:
- *
- * <programlisting>
- * myth://xxx.xxx.xxx.xxx:6543/filename.nuv
- * </programlisting>
- *
- * This URI will say to the gmyth library to configure the Recorder instance (used to
- * change the channel, start the TV multimedia content transmition, etc.), using
- * the IP address (xxx.xxx.xxx.xxx) and port number (6543) of the MythTV backend
- * server, and setting the channel name to "BBC".
- *
- * Another possible way to use the LiveTV content, and just in the case you want to
- * use the mysql database, put the location URI in the following format:
- *
- * <programlisting>
- * myth://mythtv:mythtv@xxx.xxx.xxx.xxx:6543/?mythconverg&channel=9
- * </programlisting>
- *
- * Where the first field is the protocol (myth), the second and third are user
- * name (mythtv) and password (mythtv), then backend host name and port number,
- * and the last field is the database name (mythconverg).
- * </para>
