Workflow Automation

The software counterpart of the versatile Dolby® 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 can encode Dolby Atmos® content, and it also includes a high-quality single-step Dolby Digital to Dolby Digital Plus™ transcoder that preserves the metadata and minimizes tandem coding losses.
