Several 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. 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. Little by little, 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.
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. 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 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. Digital video technology can still surprise us!
