Las Vegas, April 2, 2003--Dolby Laboratories will debut Dolby® Pro Logic® II
encoding for television broadcast at the 2003 NAB show in Las Vegas (booth SU4555).
Dolby Pro Logic II encoding allows networks to broadcast a high-quality, matrixed,
five-channel surround sound signal through any existing analog or digital stereo
medium, complementing the Dolby Digital 5.1 experience delivered on HDTV and
Dolby Pro Logic II decoding, rapidly becoming a standard feature in A/V receivers and home-theater-in-a-box (HTIB) systems, transforms any high-quality two-channel source content (such as compact discs, MP3 files, and stereo broadcasts) into a lush surround sound experience. When Dolby Pro Logic II encoding is applied by a broadcaster or content provider, and later decoded by a Dolby Pro Logic II receiver in the home environment, listeners are afforded an even more exact and realistic surround sound experience.
"We are introducing Dolby Pro Logic II encoding to the broadcast industry to enable broadcasters to deliver dynamic five-channel surround sound over their existing analog or digital stereo infrastructure," said Tom Daily, Marketing Director, Professional Audio, Dolby Laboratories. "For the ultimate television experience, many broadcasters include Dolby Digital 5.1 audio. However, Dolby Pro Logic II processing offers the next-best solution for stations not currently able to make the transition to true discrete 5.1-channel audio. Our goal is to provide a variety of solutions to meet the audio needs of every broadcaster."
The DP563 Dolby Surround Encoder can now be upgraded for $400 to include real-time encoding for Dolby Pro Logic II and Dolby Surround Pro Logic. New DP563 units will come equipped with the upgraded capability of Dolby Pro Logic II encoding, and will be available after NAB for $3,700.
Dolby's NAB booth will also display a new software-based Dolby Pro Logic II encoder from Minnetonka Audio, available as a stand-alone device or as a VST plug-in.
About Dolby Pro Logic II
Dolby Pro Logic II technology provides full-bandwidth, five-channel sound for applications ranging from home theater systems to PC audio, game consoles, and in-car entertainment devices. Dolby Pro Logic II incorporates recent advances in matrixed surround decoding to achieve better channel separation than previously possible. Broadcasters and content creators can use Dolby Pro Logic II technology to provide a surround sound experience for viewers of stereo TV services with no change to the broadcast delivery infrastructure. For game developers, Dolby Pro Logic II allows nextgeneration game consoles to deliver five-channel sound with virtually no cost to the host CPU.
Dolby Pro Logic II is also fully backward-compatible with Dolby Surround Pro Logic technology, and can optimally decode the thousands of commercially available Dolby Surround movies and television shows with enhanced surround spatiality. In addition, Dolby Pro Logic II converts any high-quality stereo programming, especially music, into a natural, immersing surround sound experience.
