Configuring Live Profiles

A Live Profile is a set of audio and video settings configured to fit within specific broadcasting requirements. Live Profiles can be configured from either the Web Interface or on the Unit Front Panel.

The unit is delivered with three (3) default Live Profiles:

DEFAULT
LOW DELAY
HQUALITY 10s

Recommendations when configuring a Live Profile:

End-to-End Latency (by Application type)	Broadcast Over SST mode	For CBR, enter a value within the 500ms - 10s range. For VBR, enter a value within the 800ms - 10s range.
	Broadcast over SRT mode
	Video Return
Bitrate Control Mode	CBR mode for streaming over managed networks. VBR mode for streaming over unmanaged networks.
Resolution	As source for an encoding in the same resolution as source. Dynamic when the resolution is adapted to available bitrate (H.264 only).
Live Bitrate (static resolution as source)	Video Resolution	Bitrate Range
