Some Things You Need to Know about Digital Video
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. 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.
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, the passage from analog to digital signal became predominant with television transmissions adopting the digital video standards. 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.
At present, almost every family has at least one digital video camera, not to mention that the technology is available with all the communications devices we use today. 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; 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 the Internet abounds in programs, tools and softwares that are provided for free download. 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 has become not only relevant but characteristic of our society. And we can expect to use it in even more evolved forms over the coming decades. There is more in stock with digital video than we may know!
