It supposed to be executed on a separate computer; in this case it occupies the whole screen area of primary monitor. In case when software is running on single machine configuration, it occupies the whole area of second monitor. Image of this screen is displayed to the announcer. Another component represents controlling system for text scrolling component. It's used by operator who controls broadcasting process.

All components are implemented in C++. Text scrolling component implemented as COM-server that uses DirectDraw to render text. Controlling application is a typical Windows desktop application that communicates with text scrolling server via DCOM.
