In order to minimize the limited space allocated on a DVD for audio soundtracks, DD and DTS utilize lossy data reduction algorithms, which reduce the number of bits needed to encode an audio signal. The DVDWG mandated that any DVD carrying a DTS soundtrack must also contain one of two of the previously mentioned required soundtracks. A year after this occurrence, Digital Theater Systems (DTS) joined the soiree claiming its coding method sounded better due to higher bit rates and less compression. The DVDWG also allowed for DTS and SDDS as optional soundtracks. The DVDWG agreed, and DD was selected as 1 of 2 required soundtracks, the other being PCM, on all DVD releases in the USA.

Dolby argued that its name recognition, familiarity with the movie industry, and the choice of its system for audio coding in the new DTV standard made it a logical choice for DVD as well. When the consumer-electronics industry DVD Working Group (DVDWG) sought the best audio coding technology for the new format back in 1995, Dolby Labs jumped at the opportunity. For the first time, a fully discrete digital 5.1 channel surround format was created for both the theaters and home audio marketplace. Enter Dolby's newest creation, Dolby Digital (DD). However, this would soon not be enough for a society that thrives on the "bigger and better" mentality. With the birth of Dolby Surround in movie theaters, it was only a matter of time before we the consumers would reap the benefits of this trickle down technology into the consumer A/V marketplace. Well, I must say since then, life has gotten a whole lot better in the realm of audio. I remember the days when I used to hook up my 2 channel audio system to my mono VCR and thought life was good. The market floods with newer and newer technology, allowing consumers to be less easily impressed and more picky, sometimes loosing touch with what was involved in producing this marvel of technology that only a few years ago, would have been a nearly impossible feat. As technology improves and becomes more competitive, increased performance is realized at lower cost to the consumer. With the advent of home theater, consumers are continually demand higher performance.
