Our reference decoder for Dolby Digital multichannel audio, the DP569 is designed for digital television and disc-authoring applications, including automated broadcast installations and mastering for DVD and other recorded media.
The Dolby DP569 supports encoded bit ranges from 56 to 640 kbps and channel configurations from mono to 5.1-channel surround sound. The DP569 supports all metadata, including the Dolby Digital Surround EX™ flag that enables downstream consumer A/V receivers and decoders to recognize the format. The unit provides real-time encoding for DVD authoring facilities and allows quality-control (QC) monitoring during recording.
With reliability proven in hundreds of TV stations around the world, the Dolby DP569 offers many broadcast-friendly features. Among them, an AES reference input locks the DP569 to the transmission equipment clock reference.
The unit features selectable sample rate converters on the audio inputs. For on-air and other broadcast applications, the DP569 is capable of creating SMPTE 339M time stamp data bursts for synchronization with downstream equipment. Bypass connections enable a hot-standby mode for broadcast installations.
LTC and VITC timecode inputs allow Dolby Digital bitstreams to be time-stamped to synchronize with audio and video in DVD-authoring systems. The timecode inputs allow the encoder to stop and start accurately to create separate program segments and soundtrack files for DVD authoring.
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.
Up to 5.1 channels; encoding bit rates of 56 to 640 kbps; Dolby metadata.
A rear-panel connector provides an external metadata input from other Dolby products (for example, a Dolby E Decoder DP572).
Fault-monitoring circuits warn of actual or potential system failure (via the GPI/O port).
Front- and rear-panel serial interfaces, along with supplied application software, make it possible to configure and control the Dolby DP569 from a Windows® based PC or other remote device.
