>Well you're nice white paper is essentially telling the same as I outlined. It clearly indicates that the extension data is used to reconstruct all the samples in the decoder. The extened data doesn't contain high band frequency content only.<

I disagree and we're obviously interpreting the technical data in different ways with the confusion arising over the word "reconstruct".

"The core decoder decodes the core data and produces the core LPCM audio that is next up-sampled to 96kHz using the 48-to-96kHz interpolator."

This is very clear and open to very little misinterpretation. The core 48kHz data is upsampled before being combined with the extension data.

At no point does the document state that the extension data is used to increase the inherent resolution of the core data or how such a thing would even be possible. If you consider the practicalities involved, to enhance the resolution of the core component to 96kHz a far greater amount of data would be required than could be delivered by the extension component, unless of course DTS considers the need to exceed Nyquist unnecessary and are saving the bitpool in that way, in which case we're back to square one, a core component that is no better than 48kHz.
