The system is capable of providing the learners of foreign languages with good audio-visual conditions, composed of a main frame, a keyboard, handsets and TV connector.

Its advantage is to enjoy videos on TV. It has neither change in sound quality and nor noise in listening or conversing.

Controlled by a keyboard, the user can listen to teacher's explanation and have dialogue with teacher or other learner.

The system has the function of review, too.

Ri Jae Hun, section chief of the Educational Information Exchange Agency, told KCNA that the system has already been applied to Pyongyang Han Tok Su University of Light Industry, Pyongyang College of Statistics, Pyongyang Hasin Primary School and other educational institutions.
