• What does DTS, Dolby Digital, DivX, MPEG4 stand for and what do they do to my DVD player?
  • DTS stand for Digital Theater Systems Digital Sound and is a product of DTS, Inc. It is a multi-channel audio compression format similar to Dolby Digital. The difference between the two is that DTS generally uses higher data rates to store information the Dolby Digital. This means it has better quality audio.

    Dolby Digital uses the AC-3 file format, which any Dolby Digital Decoder can decode to produce 5.1 audio. Dolby Digital is the technical name for Dolby's multi-channel digital sound coding technique, more commonly referred to as Dolby 5.1. A six-channel sound coding process (one channel each for left, right, center, left surround, right surround speakers and a sub-woofer) originally created by Dolby for theaters, AC-3 was subsequently adapted for home use and is now steadily becoming the most common sound format for DVD.

    MPEG stands for Moving Picture Expert Group, in charge of the development of standards for coded representation of digital audio and video. It is used for both streaming and downloadable web content, and is also the video format employed by a growing number of portable video recorders. One of the best-known MPEG4 encoders is DivX, which since version 5 has been a fully standard-compliant MPEG4 encoder.

    DivX is video-encoding technology, released by a company called DivXNetworks. The DivX code is based on the MPEG-4 compression standard. This code is so advanced that it can reduce an MPEG-2 video to ten percent of its original size. DVD players including this technology will be able to perform a high standard of imaging.
