Hi we all know little bit about all things which are use in the audio visual Field.
know we see the little bit about projectors.

There are many types of projectors used in video conferencing for the display purpose.

There are main three types of projectors ...... !

1> LCD




LCD projectors start with a source of light (lamp) and split the light into three beams. Each beam passes through its own LCD panel. The LCD panels each have hundreds of thousands of tiny pixels the higher the resolution the more pixels.Data determines whether light is allowed to pass through each.

2> DLP



The vast majority of DLP projectors use a single monochrome DLP chip (officially DMD for "Digital Micro Device), and the aforementioned spinning color filter wheel to generate colors. Unless specifically noted, when this series of articles refers to DLP projectors, they are discussing single chip models

3> CRT



The full form of CRT is(Cathode Ray Tube)When video projectors first arrived on the scene, television technology was based on the Cathode Ray Tube (CRT), on which the viewer sees the television image. Three small CRTs (one for each primary color), coupled with a light magnifying lens, can project a color image onto a large screen in a darkened room. With the proper video processing circuitry, CRT size, and lens combination, a CRT projector can produce excellent high resolution images.

The basic concept is that the computer network acts as a central hub where all the participants go to connect in to the conference.

Audio output Usually consists of speakers. These speakers can range from professional equipment headphones or even tiny speakers on a laptop computer.



Hmmmmmmm know we see little bit about importance of video conferencing ..... !

Video conferencing is used by many businesses usually to save both time and money. One of the great advantages of video conferencing is that two or more parties can have a virtual face to face meeting to conduct business, which is seen as more beneficial than just a conference call. Other parties such as educators and health professionals use video conferencing when giving lectures, teaching about topics that require visual cues or visual information. Health professionals can give a diagnosis by conducting an examination via a video conference. There are many advantages to this technology and this has a lot to do with its exponential growth in recent years.

audio visual | what is conferencing | equipmensts used

Conference means when two or more people come together or share the information its called as conferencing .



Conferences can be face-to-face affairs. A salesman attends a trade show to pitch his product to hundreds of potential clients.
* There are may types of conferencing *

1> Teleconferencing.
2> Videoconferencing.
3> Web conferencing.

First we see the TELECONFERENCING ....... !

If you ever use a three way phone call you've already teleconferenced.There are two types of conference call.1(Meet-Me)& 2(Ad-Hoc).
Meet-Me :-Meet-Me conferencing requires participants to call a special phone number on a given day and time and enter an access code to join the teleconference.
Ad-Hoc :-conferencing requires a moderator to call each of the attendees individually and connect them together.



Teleconferencing has endless applications in the business world, from large corporate conference calls for shareholder earnings reports to four salesmen in four different cubicles discussing a new product.
Teleconferencing advantages are that the technology is familiar to anyone who uses a phone, it's easy to set up, and it offers good audio interactivity for small groups. Its disadvantages are that it greatly limits collaboration and interaction for larger groups, and that audio-only presentations are often less engaging to attendees.

Know we see the VIDEOCONFERENCING ....... !

This is the simplest form of videoconferencing, where the presenter appears on the screens of all the attendees in a small Web cam video window. For small groups, some software programs offer the "Brady Bunch" effect, in which all of the attendees appear on the screen in separate Web cam windows.

There is a difference, however, between this simple form of videoconferencing and what are known as Web casts. Web casts are professional-quality online video presentations, usually for larger groups and with less interactivity between participants.
