Sienna VSControl is an interface server which allows Sienna AutomationX to control Omneon's Spectrum and MediaDeck video servers. The control mechanism uses Omneon's ethernet based protocol, and Sienna is the only Mac-based automation system to control Omneon via this superior interface.

Media is automatically transferred to Spectrum or MediaDeck via Sienna MediaServices, as part of an automated Sienna workflow. Additionally Sienna is able to copy media from any production storage volume to the Spectrum / MediaDeck storage in a special mode which allows AutomationX to initiate playout from Omneon whilst the transfer is still in progress.
