Digital Video
The history of the modern digital video started back in the 70s and 80s when the analog video input was digitized by means of time base connectors and digital video effects units. The signal, effects and manipulation of the video improved considerably afterwards. More digital video equipments were created in the Bosch research labs in the 70s but the commercial introduction took longer, with the first digital video available with Sony D-1 in 1986.
In the first forms of digital video, the analog source remained essential because it served for the digitized encoding that could be read by computers. Little by little, television transmissions adopted the digital video standard when passing from the analog to the digital signal. Yet, another element that completed the digital video revolution for good was the appearance of the non-linear video systems. High definition television would not be possible without it.
All the communication devices designed and manufactured today included a digital video camera, not to mention that almost every family has such a piece of electronics in the household. Only the older phone models are camera-less. Moreover, the market has been quickly won by the popular concept of camcorder that combines a camera with a recorder. A digital video can be stored and copied without any degradation of the information; after editing, the clarity of the image is the same as at the moment when it was filmed.
Digital video applications are more numerous than just the private use with mobile phones; Internet communications and conferencing systems are the best examples here. The editing process for the applications has been simplified to a very large extent and the Internet abounds in programs, tools and softwares that are provided for free download. Windows Media and MPEG2 are the most common of Internet applications that perform digital video editing.
One can hardly express the full number of applications and the usage extent of free digital video technology nowadays. From corporate business use to home applications, digital technology has become not only relevant but characteristic of our society. And more evolved forms are expected to appear. Digital video technology can still surprise us!
