3.2 AMS server
The AMS server is used for storing files and
messages of quizzes. It is composed of DTV Exam
Service APIs and assessment data. The APIs defined
by MHP middleware provide a simple way to make
connections between server and user client. Like
runtime environment in set-top box, there is also a
program in the AMS server for transmitting data to
user clients. This application in AMS server can
transfer user-defined data embedded in digital TV
program streams.
