The first success in the creation of a digital video was reported back in the 70s and 80s when with a special effect unit and some time base connectors, an analog video input was digitized. 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. Step by step, 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. This progress contributed significantly to the introduction of the high definition television.
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. Digital video information can be stored without any danger of degradation or data corruption; 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 has been made really simple and there is an avalanche of programs, softwares and tools that make editing possible. The most common format for editing a digital video with Internet applications is Windows Media while MPEG2 is exclusively used for DVDs.
One can hardly express the full number of applications and the usage extent of digital video technology nowadays. From corporate business use to home applications, digital technology now defines our society better than ever. And more evolved forms are expected to appear. Digital video technology can still surprise us!
