The Dolby Surround and Pro Logic II Encoder DP563 lets you create surround programming for distribution via all analog and digital stereo media.
Dolby Surround and Pro Logic II Encoder DP563
The all-digital Dolby® Surround and Pro Logic® II Encoder DP563 encodes discrete four- or five-channel surround mixes into Left total/Right total (Lt/Rt) stereo for delivery via two-channel television and radio broadcasts, PC and console games, and CDs.
Lt/Rt encoded stereo content lets you provide surround sound on millions of home theater systems equipped with Dolby Pro Logic or Pro Logic II decoding, while remaining fully compatible with stereo and mono playback.
The Dolby DP563 provides two surround encoding algorithms. The original Dolby Surround algorithm encodes Lt/Rt stereo with full-range Left, Center, and Right channels, plus a limited-range Surround channel, as intended originally for four-channel Dolby Pro Logic playback.
The Dolby Pro Logic II algorithm encodes Lt/Rt stereo with five full-range channels—Left, Center, Right, Left Surround, and Right Surround—for the most natural and involving surround experience that can be delivered via stereo media.
With its six digital input channels, the DP563 can create Dolby Surround or Dolby Pro Logic II encoded stereo directly from any discrete 5.1 mix. If you're a producer of 5.1 content for DTV, you can easily create a separate mix for distribution via stereo services. With Dolby E 5.1 content, metadata authored during production can enable the DP563 to create an Lt/Rt stereo mix exactly as specified by the producers.
Look to Dolby for the comprehensive tools, content services, and solutions you need to create, distribute, and deliver the highest-quality audio and imaging content.
