The Dolby Multichannel Dolby Digital Encoder DP569 is designed for digital television and disc-authoring applications, including automated broadcast installations and mastering for DVD and other recorded media. Supporting encoded bit ranges from 56 to 640 kbps and channel configurations from mono to 5.1-channel surround sound, the DP569 is our reference encoder for Dolby Digital multichannel audio.

Features for Broadcast and DVD Authoring

With reliability proven in hundreds of TV stations around the world, the 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.

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. 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 QC monitoring during the recording process.

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), and bypass connections enable a hot-standby mode for broadcast installations.

Front-panel controls include buttons for accessing status, setup and configuration parameters, and display modes. Front- and rear-panel serial interfaces, along with supplied application software, make it possible to configure and control the DP569 from a Windows®-based PC or other remote device.

For decoding Dolby Digital material, the Dolby Multichannel Audio Decoder DP564 is an ideal companion to the DP569. The DP564 also provides decoding for Dolby Digital Surround EX, Dolby Pro Logic®, and Dolby Pro Logic II formats.
