Learning Digital Video from Past to Present
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 outcome of such experiments was the improvement of the video quality for manipulation, effects and signal. Bosch also created digital video equipments in the 70s but they remained lab research only until 1986 when the first digital video was created with Sony D-1.
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. Soon, the appearance of the non-linear editing systems would mark the evolution of electronics for good. 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. The more popular concept of camcorder (a device that combines the recorder and the camera) is winning the market as our society depends on the quick quality access to information more than ever. Digital video information can be stored without any danger of degradation or data corruption; the clarity of the sound and image remains high quality if it was filmed properly.
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 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.
It is impossible to exhaust the number of applications and the constant extent of digital video in day to day life. From home applications and corporate business, digital technology now defines our society better than ever. And more evolved forms are expected to appear. There is more in stock with digital video than we may know!
