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	For CBR, enter a value within 500ms - 10s range. For VBR, enter a value within 800ms - 10s range.
	Broadcast over SRT
	Video Return
	Broadcast (SST low latency mode)	For CBR, enter a value within 80 - 500ms range. VBR mode is not available.
Bitrate Control Mode	CBR mode for streaming over managed networks. VBR mode for streaming over unmanaged networks.
Resolution	As source for encoding in the same resolution as source. Dynamic when the resolution is adapted to available bitrate.
Live Bitrate (static resolution as source)	Video Resolution	Bitrate Range
	Video Resolution	H.265/HEVC	H.264/AVC
	2160p 50/59.94/60	3 Mbps - 80 Mbps	-

Audio Settings	Channel Layout	Bitrate Range
	1 x Mono	32 - 256 kbps
	1 x Stereo	64 - 512 kbps
	2 x Mono	64 - 512 kbps
	2 x Stereo	128 - 1024 kbps
	4 x Mono	128 - 1024 kbps
	4 x Stereo	256 - 2048 kbps
	8 x Mono (single encoding only)	256 - 2048 kbps

The following Transport Stream settings are available if the Application type is set to Broadcast (SRT):

Bitrate Control	VBR CBR
TS ID	1 - 1023
Program Number	1 - 1023
PMT PID	32 - 8183
PCR PID	32 - 8183
Video PID	32 - 8183
Audio PID	32 - 8183

Note

When starting a live in multi-encoding mode, the minimum bitrate is 4Mbps over cellular network.
In Ultra Low Latency mode, regardless of the resolution, the system is forced as H.265/HEVC in CBR mode. Under these conditions, the bitrate can be set up to 80 Mbps.
