Connect an SRT stream as an input
4. Enter the following optional settings:
l
Encryption
- select the check box and choose the AES
Key length
if the SRT destination
requires AES encryption. These settings must match the encryption settings of the
destination device.
l
Passphrase
- Enter a passphrase if one is required along with AES encryption.
l
Latency
- Add from 80 ms to 8000 ms of latency to the SRT stream. Increasing latency gives
more time to buffer packets and resend any that got lost in transit to the destination. If the
latency value set for the stream is too low and there is packet loss over the network,
retransmission of lost packets will not be possible and the stream quality will suffer.If you
require real-time responses from your audience, you should use as little latency as possible.
l
Audio delay
- The audio delay feature helps you adjust audio coming from external sources
so that your video and audio sources are synchronized when captured, streamed, and
recorded. You can apply from -300 ms to +300 ms of delay. By default, there's 0 ms of delay
applied to audio sources.
l
Enable UTC midnight-based timestamps
- This will enable syncing of SRT sources when
using Pearl-to-Pearl or Pearl-to-Unify SRT sources.
l
Use hardware acceleration
- This is the default H.264 encoding preset. Choose this setting
for best performance. (Pearl-2 and Pearl Mini only)
l
Disable color range conversion
- Color range conversion ensures that the ingested SRT
video signal is full-range RGB (0-255), even if the signal was sent with limited RGB color
range. By default, color range conversion is enabled.
l
No signal image
- Select an image to be displayed if there is no signal in the SRT stream.
from the dropdown list. The
DEFAULT
image displays the words
NO SIGNAL
. To add a new
image, select
Media
in the
Configuration
menu and click
Choose File
.
l
Timeout
- Select an amount of time with no signal before the
No signal image
appears.

We recommend using the default latency value for an initial test stream. After you perform a test stream,
you can determine the Quality of Service (QoS) and calculate the latency requirements. To set the SRT
stream latency, see
Adjust latency and view the SRT stream status
.
Hardware encoding is the default setting for a channel and is the recommended encoding for
use with Pearl Mini. However, if you are ingesting an SRT stream as a video input for a channel
and Pearl Mini does not recognize the signal, switch to using software encoding for that
channel, see
.
