DTS Unveils New Names, Logos For Surround Technologies

9/05/2006 09:59:00 AM Eastern

Agoura Hill, Calif. – DTS unveiled new names and logos for the trio of DTS-developed surround technologies appearing on HD-DVD or Blu-ray discs.

The naming system and logos are designed to communicate different quality levels to consumers, and the company will work with content providers and hardware manufacturers during the next year to promote the DTS technologies at retail, the company said.

The three names are:

  • DTS-HD Master Audio, signifying sound that uses lossless compression to deliver sound that’s bit-for-bit identical to the master soundtrack,

  • DTS-HD High Resolution Audio, which uses lossy compression techniques to deliver audio “that is almost identical to the master soundtrack,”

  • DTS Encore, which delivers 5.1 channels of audio at twice the resolution found on most standard DVDs.

The DTS technology appearing on traditional DVD discs is called DTS Digital Surround, as before.

“We created this system to best serve content providers, hardware manufacturers as well as consumers as the industry makes the transition to a high definition world,” said Brian Towne, DTS’s senior VP of the consumer/pro division.

Here’s what each technology delivers:

DTS-HD Master Audio: HD Master Audio delivers sound that is bit-for-bit identical to the studio master at very high variable bit rates that are significantly higher than standard DVD bit rates. It can deliver up to 7.1 audio channels at a 96k sampling frequency with 24-bit depths. The DTS-HD Master Audio bit stream also contains the DTS 1.5 Mbps core for compatibility with existing DTS-enabled home theater systems but with delivery of 5.1 channels of sound at twice the resolution found on most standard DVDs, the company said.

DTS-HD High Resolution Audio: This also delivers up to 7.1 channels of sound but uses lossy compression techniques to deliver audio that’s “virtually indistinguishable” from the original soundtrack, the company said. It provides audio at high constant bit rates at up to 7.1 channels of 96k/24-bit quality “to provide rich, high-definition audio on content where disc space may not allow for DTS-HD Master Audio,” DTS said. The DTS-HD High Resolution Audio bit stream also contains the DTS 1.5 Mbps core for compatibility with existing DTS-enabled home theater systems.

DTS Encore : The original DTS surround technology designed initially for DVD players, this technology delivers 5.1 channels of audio at 1.5 Mbps, or “twice the resolution found on most standard DVDs, thereby providing the best sound performance possible from currently existing DTS-capable equipment,” the company said.

Because of space limitations on standard DVDs, most DVD content featuring DTS surround sound is encoded at 756kbps, but with the introduction of the new higher capacity high definition optical disc formats, consumers will be able to experience DTS at a full 1.5 Mbps through their existing surround-sound systems.
