DTS CDs are encoded in 5.1 surround sound using the DTS compression algorithm. As such, the fidelity is of lower quality than the sound quality offered by CDs, DVD-Audio discs, and SACDs. DTS CDs are not encoded in stereo. You can play DTS CDs in three ways:
* On a CD player connected to a 5.1-channel receiver or pre/pro with a DTS decoder via an optical or coaxial digital cable.
* On a DVD-Video player with the "DTS Digital Out" logo on the front panel (meaning any player available today) to a 5.1-channel receiver or pre/pro with a DTS decoder via an optical or coaxial digital cable.
* On a DVD-Video player with a built-in DTS decoder connected to a 5.1-channel receiver or pre/pro via the 5.1-channel outputs (i.e., six RCA cables).
The DVD-Audio format offers the capability of stereo and surround sound (5.1) playback at higher resolution than the CD (and therefore, higher resolution than DTS too). DVD-Audio uses PCM as the encoding algorithm like the CD, but while the CD is limited to encoding in 16-bit/44.1-kHz PCM, DVD-Audio can offer up to 24/192 in stereo and 24/96 in surround sound. In practice, the wordlength (the number of bits per pulse) on DVD-Audio discs can vary, though a 24-bit word is far and away the most prevalent. However, the sampling rate (in kHz) varies widely on DVD-Audio discs. In most cases, stereo tracks are presented in 24/96, but some discs are encoded 24/88.2 or 24/48, and some are encoded at the maximum 24/192. Most surround-sound tracks are encoded at 24/96.
The vast majority of DVD-Audio discs offer a high-resolution surround-sound track, and some also offer a high-resolution stereo track as well. Most discs also have DVD-Video-compatible Dolby Digital and/or DTS surround-sound tracks as well.
Note that to play DVD-Audio tracks, you must have a DVD-Audio player. Some are available through www.crutchfield.com , Best Buy, and Circuit City. Again, with a DVD-Video player, you can play Dolby Digital or DTS tracks that may be encoded on a DVD-Audio disc.
