DP 600C

The Dolby DP600-C Program Optimizer offers all the capabilities of the DP600 base model and adds faster-than-real-time file-based encoding, decoding, conversion, and transcoding between the following formats: Dolby Digital, Dolby Digital Plus, Dolby Pulse, and Dolby E bitstreams; as well as PCM, MPEG-1 LII, AAC, HE AAC, and HE AAC v.2. It also offers a unique, high-quality, single-step Dolby Digital to Dolby Digital Plus transcoder that preserves the metadata and minimizes tandem coding losses.

Automated Loudness and Metadata Correction

Content producers and broadcasters can reduce loudness complaints by using the DP600 to provide viewers with a consistent audio experience across programs, channels, and networks. Expanding upon the unique Dialogue IntelligenceT technology developed for the Dolby LM100 Broadcast Loudness Meter, the DP600 normalizes the loudness of audio programs while preserving their original dynamic range.* The DP600 analyzes the loudness of file-based audio bitstreams coded in Dolby Digital, Dolby Digital Plus, Dolby Pulse, and Dolby E, and validates and corrects the dialnorm audio metadata parameter without the need for decoding and reencoding the original audio bitstream. The DP600 also provides intelligent speech-based loudness normalization for both PCM (.wav and .aiff) audio and MPEG-1 LII audio.

* In very rare cases involving extreme loudness corrections that require gain, soft limiting will occur only during program peak levels that would exceed clipping after applying this type of loudness correction.

Audio Encoding/Decoding and Conversion

The DP600-C version of the Program Optimizer provides faster-than-real-time file-based encoding, decoding, and conversion between all of Dolby’s audio formats (Dolby Digital, Dolby Digital Plus, Dolby Pulse, and Dolby E) as well as PCM, MPEG-1 LII, AAC, HE AAC, and HE AAC v.2, while preserving the audio metadata.

In addition, it offers a unique, high-quality, single-step Dolby Digital to Dolby Digital Plus transcoder that preserves the metadata and minimizes tandem coding losses. This allows the audio from existing media archives to be converted to next-generation broadcast formats. The DP600 also supports Dolby Pro Logic® II encoding for two-channel matrix-encoded content derived from multichannel source files.

Upmixing Functionality

Customers interested in enhancing two-channel audio for use in 5.1-channel applications can purchase an optional software upgrade that adds an intelligent file-based upmixing capability to the DP600. This unique process is based on a newly developed Dolby algorithm that creates a wider natural-sounding sweet spot. It also ensures that subsequent downmixing is free from artifacts typically found with other solutions. The upmixing process can be adaptively integrated into the same DP600 work-flow profiles utilized for file-based loudness correction, encoding, decoding, conversion, and transcoding.

Work-Flow Flexibility and Ease of Use

The Dolby DP600 platform supports several types of applications, including archiving, automated quality control, content conversion, and media asset management, and offers considerable potential for integration with third-party systems through an open Web services-based API. In recognition that not all users require a high level of integration, the DP600 also features a hot folder ingest process that is simple to set up and use. In this mode, users can select a specific profile, and all media files moved to the hot folder will be automatically processed based on the profile and delivered to a user-defined folder upon completion.

Ready for the Future

The Dolby DP600 Program Optimizer is designed with future extensibility in mind, maintaining support for the latest broadcast and audio file formats and the most up-to-date Dolby innovations.
