• Dolby Program Optimizer VM600

    For broadcast operations that are shifting to virtual workspaces, Dolby has created the VM600 software platform, which builds on the capabilities of our innovative DP600 hardware. Now you can have a file-based workflow solution for loudness correction, audio conversion, and upmixing.

    Screen capture: The Dolby VM600 can process up to 16 work orders simultaneously.

    Workflow Automation

    The software counterpart of our versatile DP600 and DP600-C hardware platforms, the Dolby® Program Optimizer VM600 can simplify and automate your broadcast workflows. We designed it specifically for cable, satellite, IPTV, terrestrial TV, OTT, radio, and postproduction facilities.

    Loudness Law Compliance

    Responding to consumer concerns, many countries regulate broadcast loudness. The Dolby VM600 offers you a simple, effective, and scalable way to ensure compliance with CALM and with EBU loudness laws.

    Comprehensive Processing Capabilities

    The Dolby VM600 can encode, decode, convert, or transcode audio between a number of popular file formats alone or within media containers, using your own virtual infrastructure and storage systems. It also includes a high-quality single-step Dolby Digital to Dolby Digital Plus™ transcoder that preserves the metadata and minimizes tandem coding losses.

    Dolby Loudness Solutions

    Dolby has been at the forefront of research into loudness problems, developing innovative solutions to overcome them. Our solutions work together to ensure the best possible viewer experience.

    Features

    • Audio Encoding/Decoding and Transcoding

      Provides faster-than-real-time file-based encoding, decoding, and conversion between all Dolby audio formats (Dolby Digital Plus, Dolby Digital, and Dolby E), and PCM, MPEG-1 LII, AAC, and HE AAC v2, while preserving the audio metadata.

    • Automated Loudness Analysis and Correction

      Delivers a more consistent, reliable, and high-quality experience without the need to manually validate and correct each piece of media. The virtual form factor allows jobs to be processed up to 12 times faster than on the DP600.

    • Patented Dialogue Intelligence Algorithm

      Delivers effective speech-based loudness normalization and automatically sets and/or corrects dialnorm values within media files without the need for decoding and reencoding.

    • Automated File Conversion and Transcoding

      Simplifies conversion of archives to next-generation formats. The high-quality, single-step Dolby Digital to Dolby Digital Plus transcoder preserves the metadata and eliminates transcoding losses.

    • Intelligent Upmixing Capability

      Enhances legacy two-channel content with our unique stereo-to-5.1 algorithm that creates a wider, natural-sounding sweet spot and ensures elimination of artifacts in any subsequent downmixing.

    • Hot Folder Mode

      Simplifies integration into existing workflows. Select a specific profile, and all media files moved to the hot folder will be automatically processed to that profile and delivered to a folder you define.

    • Two Configurations

      The Dolby VM600 is available in two versions to fit your workflow requirements: one that allows eight simultaneous work orders and another that allows 16.

    System Requirements

    The Dolby VM600 runs in a virtual machine environment and can be deployed in either VMware® vCenter 5.1 clustered servers or as a stand-alone virtual machine with the VMware Workstation™ 10.0 application.

    The following server and storage configurations are provided as examples only. Your specific requirements will vary greatly depending on your workflow requirements, so a consultation with Dolby sales and support is highly recommended prior to purchase.

    Example Configuration 1 – Long Form Content

    CPU: Dell™ R720 Dual Intel® Xeon® E5-2680 2.70 GHz*
    RAM: 16 GB minimum, 32 GB or greater recommended
    Storage: Hitachi® Unified Storage 130 or EMC® VNX5500™

    Example Configuration 2 – Short Form Content

    CPU: Dell R720 Dual Intel Xeon E5-2609, 2.4 GHz*
    RAM: 8 GB RAM minimum, 16 GB or greater recommended
    Storage: Internal RAID or SSD

    *The number of cores required depends on the number of simultaneous work orders you intend to run. VM600 can be purchased in two configurations (8 or 16 simultaneous work orders). Depending on your processing profiles, you may want to dedicate anywhere from one to three physical or virtual cores per work order.

    Storage

    During the Dolby VM600 install process, you can provision multiple hard drives for a virtual machine as follows:

    • First drive: System and database partitions (and scratch space if no other drives are present). 
    • Second drive: Scratch space for work orders. (If only two drives are provisioned, this is used for all work orders.) 
    • Second through nth drives: Scratch space for individual work orders. 

    Some example storage setups:

    If you are running VMware File System 5, and can provision disk sizes larger than 2 TB, consider:

    • One 500 GB system drive

    • One 8 TB or 16 TB scratch drive, depending on your license allowance 

    If you cannot provision disks larger than 2 TB, then we suggest:

    • One 500 GB system drive

    • Either 8 or 16 additional drives, each of 1 TB 

    Short content with network storage available:

    • One 500 GB system drive 
    • One 2 TB scratch drive


    Short content with local RAID array available:

    • One 500 GB system drive 
    • One 2 TB scratch drive

    License Server System Requirements

    For copy protection, the Dolby VM600 license server requires a separate PC running either Windows® 7 or Windows Server® 2008 (32 or 64-bit). Multiple VM600s in the same facility can all connect to a single license server.
