Bandwidth Management
The Bandwidth management section provides a method to set a maximum bit rate for the
encoded stream. It duplicates the Control mode settings already described in the Standard
Control
area (already described above) but includes two additional modes of control.
Figure 24. Bandwidth Management Section
Control Mode: Manual Frame drop
In this mode, the spatial image quality is held constant. However, a bit rate limit is applied
and maintained by controlling the frame update rate whenever this limit is exceeded. The
frame rate is managed by setting a value for the Frame Drop Percentage. This is the
percentage of frames that are dropped whenever the bit rate limit is exceeded.
Control Mode: Shared Flow rate
This mode is the same as the Peak flow rate but the bit rate control is applied to the
aggregate value for all streams from the encoder, as would be the case if multiple
(maximum 4) Unicast streams are chosen as the data transport method.
Streams Panel
The streams panel provides statistics on all of the active connections running on the encoder.
Figure 25. Streams Panel Section
The bit rate figure that is reported here is the total for all streams, including video, ancillary
(audio) and FEC.
