The main advantages provided by this technology are:
• largeness of the geographic area covered
• fixed costs of transmission even at increasing numbers of
receiving stations
• high scalability level
• no limits of destination accessibility
The teacher/speaker can make his lesson/speech in any of the transmitting/receiving rooms of the CSS, by using his own laptop computer or by copying his lesson from any mass storage device. An instant messaging connection, active during the lesson, permits the students to send questions or comments to the teacher/speaker.
The CSS system allows also the deferred download through Internet, at any time, of previous lessons/events, by contacting a specifically developed web-based event repository service.
