Tutorial on How to Use Interactive Video Conference Term Paper

Introduction

Advancement in communication technology has presented the world with unbelievable costs effective and time saving face-to-face online meeting in interactive video conference. Professionals do not need to travel to meet their clients and every end of the globe can be reached with a click on the mouse. This is quite interesting because, not long ago, businesses had to incur heavy costs on communications. Besides, telephone conference was less effective as the involved, could not see face-to-face. This technology of video conferencing has been widely utilized by leaders of governments such as United States and Russia as well as other countries in the world to interact without covering thousands of miles for a meeting. This has effectively saved on airline costs as well as other operational expenses. This paper will give a systematic tutorial on the application of interactive video conference (IVC) with an in depth description of its basic equipments.

Interactive video conference

Video conference, also known as video-tele-conferencing is defined as a group of interactive telecommunication tools that permit two or more localities to network through a two-way audio and video broadcast simultaneously. It is important to note that video conference differs from other interactive technologies like videophone calls, which are designed for individuals as opposed to conference. Video-conferencing process occurs in an IVC room, which is equipped with all the relevant tools for its execution. The room is usually networked by video codec propriety software for connectivity and is designed by polycom.

Equipment in the IVC Room

IVC or polycom rooms contain several tools used to facilitate videoconferencing. These tools use an AMX touch panel, utilized as the controller panel or interface for operations of rooms. Equipments used in polycom rooms include:

• Monitors and video projectors
• Three Cameras, these are meant for student, document and instructors
• Push-to-talk-microphones
• DVD/VHS player
• VHS recorder
• Manual microphone controls for students
• Smartboard
• Chairs and tables, between 24-48
• Multimedia PC
• Internet access.

There are also roll about units, used by instructors for virtual meetings among others. These units contain two cameras, VHS/DVD deck, carts, desktop microphones and two cameras. Austin Community College (ACC) offers training on IVC as well as certification to help its staff, faculty and clients gain experience with the equipment and maximize their efficiency. Before any instructions are delivered, the instructors take two-three-hour workshops to ensure they switch to IVC from face-to-face instructions as well as improve on quality. These training workshops include Introduction to IVC, which is meant for those faculty members new to IVC technology or those who need to refresh. The other, is IVC advanced topics, meant for ACC instructors, and is vital in providing hands-on experience with IVC equipment. However, other members simply need to take Introduction to IVC with other specific trainings as needed.

IVC Equipment Training

To operate IVC equipment, you need to be able to first, identify each of them, their uses and follow systematic instructions below. This requires knowledge of all equipments contained in polycom room, as well as their correct usage. IVC room contains the following consoles, Desktop, instructor and cabinet.

Instructor guidelines

Instructors have options to set manual or auto for the student-push-to-talk microphones, they are required to set the microphone to manual when calling on a specific student, or turn to auto, which allows for first- push-first -talk mode for the students. The microphone is as shown below.
