Learning About Digital Video Profoundly

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. 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.

The first types of digital video formats depended on the use of an analog source that served as the starting point for the digitized encoding in computer-readable patterns. 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. 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. There is hardly any mobile phone model that does not incorporate a digital video camera.

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; after editing, the clarity of the image is the same as at the moment when it was filmed.

Besides the combined use with mobile phones, digital video has lots of applications with video conferencing systems as well as with communications on the Internet. 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.

One can hardly express the full number of applications and the usage extent of digital video technology nowadays. 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!
