Digital Video
The history of the modern digital video started back in the 70s and 80s when the analog video imput was digitized by means of time base connectors and digital video effects units. 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. Little by little, the passage from analog to digital signal became predominant with television transmissions adopting the digital video standards. 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.
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. 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. 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.
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.
It is impossible to exhaust the number of applications and the constant extent of digital video in day to day life. From corporate business use to home applications, 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!
