Connect an SRT stream as an input
3. In the Connection mode field, select the SRT mode:
a. For Caller mode, enter the following:
l
URL - the URL of the SRT source (encoder) using the format
srt://<encoder-ip-
address>:<port>, where the <encoder-ip-address> and <port> could be a Pearl device
sending an SRT stream.
l
Source port - enter the port number for Pearl Mini to use for SRT traffic.
l
Stream ID - In the Stream ID field, enter a unique name for this stream.
b. For Listener mode, optionally enter the following:
l
Enter the Port number for this device to use for SRT traffic. See
Network ports used by Pearl
Mini
to determine available ports.
c. For Rendezvous mode enter the following:
l
URL of the SRT source (encoder) using the format
srt://<encoder-ip-address>:<port>,
where the
<encoder-ip-address> and <port> values are provided by the SRT encoder
device.
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
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.
5. Click Apply.
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,
