Using Your Video Input

Video input has been around for a long time, and it helps us watch everything from our favorite shows to the morning and evening news. Of course this kind of technology was first used by the eggheads at NASA. They gave us video input and for that 6 billion people are grateful. If it wasn't for NASA we might never have gotten this video input and our own technology would have been pushed back possibly 50 years. That is a scary fact but NASA made sure that we never fell behind.

Video teleconferencing has been with us for quite some time.  Dating back to the early days of television with video input, a video teleconference could be seen in everything from the evening news to a football game.

Using a video input and audio input, NASA was the first group to use video teleconferencing as a means of communicating through live video feeds.   Using a video input, the technicians at NASA hooked up live action feeds between astronauts revolving in space and the command center.  This was an expensive and complicated system.  The most widely used teleconference was that which used audio input.

These days video teleconferencing is an every day occurrence.  Faced with the daunting task of communicating with divisions on opposite sides of the world, large corporations use video teleconferencing with video input and audio input to hold meetings in real time across the ocean.  This system has saved millions of dollars that would have normally been spent either flying the required persons in or using the telephone at great expense. 

 The concept of video teleconferencing is simple.  Using a video input as well as an audio input, people hook up through a series of signals that are moved back and fourth over lines, similar to phone lines.  Utilizing special equipment, these conferences take place in real time with little or no delay between the two places involved in the conference. 

Video inputs and audio inputs have been greatly improved since the days of NASA's use.  With the advent of digital imagery and audio, the quality is also improved. 

Speed is of great importance to people who take part in video teleconferencing.  In days past, Internet connections were slow and somewhat unreliable.  This was in part because of old technology being used to support new advances.  It was determined that old analog telephone lines could not support the massive amounts of information that were zipping along via the Internet. 

At great expense, most of which was past along to the customers, phone companies replaced old analog phone lines with new higher speed digital lines that are capable of moving signals much faster and hold up better under the stress.

The advent of broadband Internet has made dial up phone Internet connections nearly obsolete.  Operating at speeds up to fifty times faster than standard phone based service, broadband has dwarfed the competition.  The main downfall is the cost, which is sometimes twice, what one would pay for standard service.

By opening the lines of communication through a video input, many companies have made it possible to work from home, a far more comfortable setting for most people.  Though not widely used, work from home teleconferencing has revolutionized industries.  The need for large support staffs housed in expensive office buildings can be cut in half when video input teleconferencing is used. 

The main necessary component in video teleconferencing is a video input device.  There are several options but the most popular is a simple web cam.  Available all over for less than twenty dollars, a web cam is a simple device that lets just about anyone video teleconference with anyone else who also has a web cam.
