the higher capacity of high-resolution discs serves up DTS at twice the bit
rate used on DVD-Video discs.

DTS-ES Matrix DTS Extended Surround adds a single surround back channel to DTS 5.1 • DTS-ES Matrix
digital surround sound. The Matrix version includes the surround back
channel information “matrixed” into the left and right (side) surround
channels, for compatibility with 5.1-channel systems.
DTS-ES Discrete DTS-ES Discrete is another Extended Surround mode that adds a surround • DTS-ES Discrete
back channel, but this information is encoded discretely on the disc, and
is not derived from information contained in the surround channels.
