Cinema DSP is a unique technology that enables movies to be heard with the same degree of realism and impact as the directors and sound engineers intended. Cinema DSP puts you inside the scene.
With Dolby Pro Logic movie soundtracks (found on VHS cassettes and stereo television broadcasts) Cinema DSP expands the decoded surround information into a more diffuse, more enveloping experience than standard Dolby Pro Logic. There are two sound fields created: a Presence sound field in the front, and one Surround sound field in the rear.
With Dolby Digital and DTS (Digital Theatre Systems) Surround, Cinema DSP projects three sound fields into the home theatre: a Presence sound field in the front and two Surround sound fields in the left rear and right rear. The Presence sound field supplies the dialogue, music and effects, while the Surround fields are independent stereo sound fields that create a large-scale surround environment, resulting in a powerfully realistic three-dimensional soundscape.
