Why is DVD so popular?

Digital video recording is a recording format that involves the use of digital bits to represent a sound wave or image sequence so that the storage thereof can be immaculate and without loss of any quality over the duration of its journey from the video source to the ultimate destination, the viewer or the recording device, or without loss of quality due to the gradual deterioration of the recording medium. The purpose is to replace analog recording technology, as this is inferior due to the abovementioned natural traits of analog recording. The signal and recording thereof is far too susceptible to the damage due to time and distance.
The first Digital Video Recording format was the Sony D1 format, which utilizes a standard definition component video signal and does not compress that signal. This format was integrated in 1983. This format was known to be highly expensive though and was not commonly used among the public, but generally, use was confined to large television companies. This was due to this fact that the recording format was duly replaced by a much less exorbitant system that made use of data compression. Sony Betacam was a prominent one, and is still utilized very much in today’s advanced industry. 1990 was the birth of quicktime in its basic rough form, a product from Apple Computers that helped greatly in making the advantage of digital recording available to the larger consumer element of the public. The span of 15 years has seen drastic positive advancements in the field of digital recording as the introduction of mpeg 1 and mpeg 2 data formats, which were apparently developed for use in television signal transmitting and also in DVD recording media, made the quality that the average pc user could dabble with far greater. When DV format was brought about, it made editing a walk in the park compared to the lengthy process before, as cutting up and reordering streams of tape into desirable segments was replaced by on screen programs that could suspend digital representations on the pc screen of the video data, turning the average user into a video wizard.
Digital audio technology has been developing for a longer period of time than that of digital video. The abundant usage of digital technology is due to the great benefits it offers to mass production and easy quick editing of sound and music. Digital data compression formats are put into use here probably for the simple reason that the human system of sound processing when it comes to music and television is not precise. One does not sit and process each and every individual piece of sound that runs along simultaneously through a song or TV program or news broadcast. The human mind has a clever way of simplifying its task by focusing on symbolic entities such as a word or a familiar instrument or what have you. It listens to the sound as a whole, and interprets it at its own pace rather than doing it linearly. This is probably why music can be so enjoyable, because we pick up new elements to a piece of music every separate time we listen to it. Conclusively, it is for this reason that sound can be recorded in digital, and it only appears to enhance the listening experience.
