    24  * MythTVSrc allows to access a remote MythTV backend streaming Video/Audio server,

    25  * and to render audio and video content through a TCP/IP connection to a specific

    26  * port on this server, and based on a known MythTV protocol that is based on

    27  * some message passing, such as REQUEST_BLOCK on a specified number of bytes, to get

    28  * some chunk of remote file data.

    29  * You should pass the information aboute the remote MythTV backend server

    30  * through the <link linkend="GstMythTVSrc--location">location</link> property.

    31  * </para>

    32  * <title>Examples</title>

    33  * <para>

    34  * If you want to get the LiveTV content (set channel, TV tuner, RemoteEncoder,

    35  * Recorder),

    36  * put the following URI:

    37  *

    38  * <programlisting>

    39  *  myth://xxx.xxx.xxx.xxx:6543/livetv?channel=BBC

    40  * </programlisting>

    41  *

    42  * This URI will say to the gmyth library to configure the Recorder instance (used to

    43  * change the channel, start the TV multimedia content transmition, etc.), using

    44  * the IP address (xxx.xxx.xxx.xxx) and port number (6543) of the MythTV backend

    45  * server, and setting the channel name to "BBC".

    46  *

    47  * To get a already recorded the MythTV NUV file, put the following URI:

    48  *

    49  * <programlisting>

    50  *  myth://xxx.xxx.xxx.xxx:6543/filename.nuv

    51  * </programlisting>

    52  *

    53  * This URI will say to the gmyth library to configure the Recorder instance (used to

    54  * change the channel, start the TV multimedia content transmition, etc.), using

    55  * the IP address (xxx.xxx.xxx.xxx) and port number (6543) of the MythTV backend

    56  * server, and setting the channel name to "BBC".

    57  *

    58  * Another possible way to use the LiveTV content, and just in the case you want to

    59  * use the mysql database, put the location URI in the following format:

    60  *

    61  * <programlisting>

    62  *  myth://mythtv:mythtv@xxx.xxx.xxx.xxx:6543/?mythconverg&channel=9

    63  * </programlisting>

    64  *

    65  * Where the first field is the protocol (myth), the second and third are user

    66  * name (mythtv) and password (mythtv), then backend host name and port number,

    67  * and the last field is the database name (mythconverg).

    68  * </para>
