It basicaly uses SOAP to control the TV.
You can send a key like channel down, channel up, volume control ... everything the iPhone App can do to.
Example:$tv = new vieraControl;
$tv->host = "192.168.5.122"; // replace with the ip address of your tv
$tv->sendKey("NRC_CH_DOWN-ONOFF");
?>
This example will change the channel.
There is a keylist in the vieracontrolclass.php file.
User 'Remote32' from coccontech forum found out some more commands:
NRC_HDMI1-ONOFF
NRC_HDMI2-ONOFF
NRC_HDMI3-ONOFF
(switches the input to HDMI1, HDMI2 or HDMI3)
