Bandwidth Licence in Delta was introduced with Delta 2.5, based on the output bandwidth (not media bandwidth). So, for example, a server driving 8 × HD 60 Hz projectors, the output bandwidth in GB/s would be calculated as (7680 × 2160 × 3[RGB] × 60) / (1024 × 1024) = 2.78 GB/s. All new servers shipped with Delta 2.5 carry an output bandwidth number relating to the bandwidth for which the server was specified at the point of sale.
The default licence value for all servers not previously specifically licensed for output bandwidth, is 4 GB/s.
The licensed bandwidth for a server can be seen in the DeltaServer dialog: About > About Server (below, left).
In DeltaGUI: Help > About GUI (below right) this will show red if it exceeds the licence limit:
If the licensed bandwidth is exceeded, each output will show a moving watermark stating ‘Licensed Bandwidth Exceeded’, and the Stats display will show usage versus licence in red:
An example of when the bandwidth licence could be exceeded would be if the timeline frame rate has been changed from 30 fps to 60 fps, or the resolution of the connected display is higher than specified at the point of sale.
If you wish to operate beyond the preset bandwidth of a server, please contact us at info@7thsense.one. It will sometimes be the case that we need to supply upgraded hardware components and/or move to you into a more powerful base platform to suit increased performance requirement.
Note that if you update to a current DeltaServer software build with an old license, you may need to receive a licence update from us. Please contact us at info@7thsense.one for assistance.
