  2. Outline • What? • Why? • Equipments needed? • Preparations before the conference • Videoconference in action • Exercise for today JOY/ Sirpa Torvinen

  3. What is a videoconference? • real-time discussions • via the network connections (IP/ISDN) • with picture AND sound connections • between at least two participants • e.g. virtual meetings, seminars, distance lectures, supervising etc. JOY/ Sirpa Torvinen
