Term of the Week – DTS-ES

I love the terms of the week feature by the About.com crew, it is a quick yet informative method to teach people a little bit more anout HT before they go spend their hard earned dollars. This week's term is DTS-ES. 

From the article: 

DTS-ES Matrix can create a center rear channel from existing DTS 5.1
encoded material, while DTS-ES 6.1 Discrete requires that the software
being played already has a DTS-ES 6.1 Discrete soundtrack.

DTS-ES and DTS-ES 6.1 Discrete formats are backwards compatible with 5.1 channel DTS Receivers and DTS encoded DVDs.
