Adaptive Bit Rate
NOTE: Adaptive bit rate applies to a DM-NVX-36x(C) device that functions as
a transmitter.
Adaptive bit rate functionality enables a DM NVX transmitter to automatically set the
bit rate required for the input resolution of the stream; for example, the adaptive bit
rate for a common resolution such as 1920x1080p@60Hz (1080p60) is automatically set
to 400 Mbps. Adaptive bit rate makes better use of the available bandwidth.
The following table lists common resolutions and the associated adaptive bit rate
setting.
