3.2. Push XML Data
3.2.1. Push Mechanism
Push may be kicked by PC Client which operator uses.
Push is achieved with 2 steps.
First step is to send trigger.
Second step is to get XML data. (This is same as the description of "Get XML data".)
HTTP Server sends a Link XML data as Trigger, which describes the behavior of TGP/HDV, to "Push Port"
by using HTTP POST.
When TGP/HDV catches the Link XML data, TGP/HDV executes Push Event process.
