The history of the modern digital video started back in the 70s and 80s when the analog video input was digitized by means of time base connectors and digital video effects units. The signal, effects and manipulation of the video improved considerably afterwards. 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, 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.
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. Moreover, the market has been quickly won by the popular concept of camcorder that combines a camera with a recorder. 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. Windows Media and MPEG2 are the most common of Internet applications that perform digital video editing.
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!
