What is the video?
Video is a form of remote communication that allows the user not only to transmit a voice signal, but also a visual video signal. The concept has existed since the 1960s, but has never caught up with the general public to the extent that manufacturers expected it. The concept of Videophon is alive in the public's mind and is represented by virtually every depiction of the technological future - from Jetsons to modern sci -Fi movies. The idea of the video seems to be reasonable enough; Given that people like to hear the voices of the other in communication, they would also enjoy seeing who they are talking to in real time. In practice, however, all slow frames, expensive technology and lack of versatility have helped to prevent Videophon from becoming a ubiquitous method of communication.
While the actual VideoPhone technology is to run the high -speed lines and offering excellent frame frequencies when the video first PR firstOvedl his real introduction to the general public was limited to existing telephone lines and their seriously limited bandwidth. This has limited the video to 15 frames per second, which, when it is associated with jumps in the picture from the noise of the line that speaks through the video, a highly unpleasant experience. Better VideoPhone technology was also historically beyond the price that most consumers were willing to pay for a new technology of the infested errors. The video could easily cost five to ten times more than a decent wireless phone, a price that many people could not justify expenses. In recent years, the cost of video has decreased significantly, but it seems that new technologies such as webcams that videoophone can be rendered.
Given the difficulties in obtaining acceptance, the video has another major failure on the market. As with many developing technologies, the first users found that they had no one to connect with the use of their video. INSeeing that a critical number of consumers were not achieved fast enough, many of those who originally purchased a video color did not have to replace it as soon as it worries, because the user often had only one or two friends who also had a video to call.
One area in which VIDEO enjoyed a relatively large amount of popularity is in the business world. Using high -speed lines, many businesses use video phones, of course, to perform remote meetings. Many of them use the capabilities of conference calls to meet the entire albums without having to fly to the same place.
with the advent of high -speed Internet and extremely cheap digital camcorders, also known as webcams, the concept of videoophone returns, albeit in a somewhat different form. Using many Voice Over IP technologies (VOIP) users can talk to friends or clients when using their website. The idea is basically stItem as the idea of a video, except that instead of being an integrated hardware package running via existing telephone networks, a technology interface with an existing computer and internet network.
