DVCi HD video system

NETmc Marine, a leading supplier of digital video recorders to the ROV and commercial diving market since 2000, has developed a new type of High Definition video recording
system, the DVCi, designed for the structural and pipeline inspection market.

Typically, due to data rates in excess of 1Gbps, the use of an HD SDI camera on an ROV requires expensive upgrades of umbilical, connectors, mux and sliprings, as well as new
distribution systems and monitors to enable a full HD experience to be achieved. NETmc Marine's DVCi system uses the latest compression technology to reduce the data rate to
below 2Mbps, this is sufficiently low that it can be transmitted though standard video coax, twisted pair cable or via ethernet with no loss in resolution.

Due to the low data rates it is possible to install multiple DVCi cameras on an ROV for use in pipeline inspections.

The DVCi is a complete subsea camera and topside recording system. No other upgrade of equipment is required. The topside recorder manages the MPEG4 H264 files and also
facilitates the camera's configuration. Functional controls for setting the optical zoom, auto / manual focus, and other interactive functionality are via the topside GUI.
