      • Comprehensive Dolby Digital Encoding Capabilities

        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.

        Broadcast Friendly

        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.

        Ideal for DVD Authoring

        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.
