NVS-20
Video bit rate and mode
The NVS-20 video bit rate is the conversion level from video into data so that
it can be sent across an IP network. The higher the bit rate the better the
quality of the picture. For example; Standard Definition pictures may look
acceptable at 1000 Kbps. However, High Definition pictures may be
unacceptable at 1000 Kbps. Also remember that high bit rates will use more
bandwidth across the IP network. This may be okay within a Gigabit office
LAN but may be limited by the speed / bandwidth of your internet connection.
The NVS-20 also has two bit rate modes VBR or Variable Bit Rate and CBR or
Constant Bit Rate. Set the NVS-20 to VBR to efficiently send video data
across an IP network but this is also a trade off against picture quality. CBR
provides better video quality but is less data and bandwidth efficient when sent
across an IP network.
NOTE: All setting changes will not be actioned on the NVS-20 until the Apply
button has been clicked and the NVS-20 configuration progress bar has
completed at 100%.
