1.7 - * When using the LiveTV content, put the location URI in the following
1.8 - * format:
1.9 + * If you want to get the LiveTV content (set channel, TV tuner, RemoteEncoder,
1.10 + * Recorder),
1.11 + * put the following URI:
1.12 *
1.13 - * myth://mythtv:mythtv@xxx.xxx.xxx.xxx:6543/?mythconverg
1.14 + * myth://xxx.xxx.xxx.xxx:6543/livetv?channel=BBC
1.15 + *
1.16 + * This URI will say to the gmyth library to configure the Recorder instance (used to
1.17 + * change the channel, start the TV multimedia content transmition, etc.), using
1.18 + * the IP address (xxx.xxx.xxx.xxx) and port number (6543) of the MythTV backend
1.19 + * server, and setting the channel name to "BBC".
1.20 + *
1.21 + * To get a already recorded the MythTV NUV file, put the following URI:
1.22 + *
1.23 + * myth://xxx.xxx.xxx.xxx:6543/filename.nuv
1.24 + *
1.25 + * This URI will say to the gmyth library to configure the Recorder instance (used to
1.26 + * change the channel, start the TV multimedia content transmition, etc.), using
1.27 + * the IP address (xxx.xxx.xxx.xxx) and port number (6543) of the MythTV backend
1.28 + * server, and setting the channel name to "BBC".
1.29 + *
1.30 + * Another possible way to use the LiveTV content, and just in the case you want to
1.31 + * use the mysql database, put the location URI in the following format:
1.32 + *
1.33 + * myth://mythtv:mythtv@xxx.xxx.xxx.xxx:port/?mythconverg
1.34 *
1.35 * Where the first field is the protocol (myth), the second and third are user
1.36 * name (mythtv) and password (mythtv), then backend host name and port number,
