Dolby Previews New Video Technologies At CEATEC 2007

Sneak peek at Dolby’s newest imaging technologies for improved contrast and brightness for certain LCD TV and higher-quality Internet video

October 2, 2007

At CEATEC today, Dolby Laboratories, Inc. unveiled details of its new dynamic range imaging technologies, Dolby® Contrast and Dolby Vision, as well as its new video content processing technology which highly improves video encoding efficiency. “Dolby is committed to providing innovative entertainment technology solutions. At CEATEC, we are demonstrating new video technologies that could transform LCD picture quality and IP-based video quality,” said Francois Modarresse, Vice President, Marketing, Dolby Laboratories. “Dolby’s surround sound technologies are world renowned, and our imaging capabilities are already modernizing how we see entertainment. For example, Dolby Digital Cinema systems deliver movies with opening night quality every night.” Dolby will be conducting technology demonstrations of its new imaging technologies at CEATEC in room 201B. Dolby’s dynamic range imaging technology, Dolby Contrast provides dramatically enhanced contrast, while Dolby Vision, combines dramatically enhanced contrast with extended brightness and dynamic range for LCD televisions with LED back lighting technology. • Dolby Contrast, leveraging light-emitting diodes (LEDs) with local dimming, provides outstanding contrast ratio and improvements to the overall image quality. • Dolby Vision adds to LED back-light units with local dimming advanced high-dynamic range algorithms, which deliver stunning images, by providing simultaneously high brightness and high-contrast ratio. In demonstrations, LCD displays with Dolby Vision deliver picture quality that virtually matches real-world visual perception of depth, detail and color. Developed for an enhanced multimedia experience, Dolby's video processing technology provides sharper, better-looking video content for PCs, portable media players, mobile phones, and digital media adapters. With greatly improved video coding efficiency, Dolby's video processing technology delivers better video quality at lower bit rates, resulting in faster downloads and more storage for video files. It also delivers higher-quality video at standard bit rates for streaming content to larger displays. This new video content processing technology is based on H.264/AVC standards.
