Abstract:

Video is a Latin word that means 'I see'. This technology includes, capturing, transmitting and replaying visual media. Video is actually the technique of turning a series of still images into moving images and the technology to do this varies through time. Video has come a long way from the black and white images that used to move much like a fast slide show just a couple of decades ago. Live video was made possible with the invention of the 'Vidicon', which was the heart of the video camera. This was first used in television cameras in the large television studios. Today, video cameras come in various shapes and sizes to match the work they are required to do. Small video cameras that fit into the palm of your hand are the most common and inexpensive cameras that produce very high quality images that can be stored on discs or video tape.
