DTS Coherent Acoustics is a perceptual audio codec. The main technique used is a QMF filter together with Huffman, ADPCM and vector quantization.
Specification can be found through the ETSI, search for DTS. Info completeing the incomplete specification can be found here [1], [2] and here [3].
The VideoLAN project has created libdts/libdca an open source implementation of DTS. Unfortunately libdts was pushed underground through patent scare tactics for a while.
