Far from the madding convention center, Dolby provided A-B comparisons of their new Dolby Contrast technology, part of their HDR ("High Dynamic Range") tech family. The interesting part is that it is a video technology, for adjusting the range of dark to light in the LED backlighting of LCD TVs. By precisely dimming the right area of the screen at the right time, contrast can be heightened as never before, for a very film-like effect. (As the exciting screen image suggests, Blu-ray and DVD playback will both benefit.)
