Open IO Support for SRT
Secure Reliable Transport (SRT) is an open source video transport protocol and technology that
optimizes video streaming performance across networks.
SRT in Media Composer is broadcast ONLY. You need an SRT application on the other end (forexample, Haivision Free Play Pro App, VLC player, any SRT enabled decoder) to watch the SRTstream. SRT enabled devices or Apps can playback the output of Media Composer.
To learn more about options for playback, visit the SRT Alliance web page: https://www.srtalliance.org and or the list of companies who now have built SRT into their cameras,encoders/decoders, players, mobile apps etc.
Note the following when working with the SRT plug-in:
Decoded Output•Due to the compressed streaming nature of SRT, and the variety of SRT decoding applications
and devices available, the decoded output may not be in sync with the Media Composer desktop.
Depending on the decoder being used, the output may be up to several seconds out of sync.
Adjusting the buffering settings in the decoder as well as the SRT latency setting can help toimprove the delay depending on your network's quality of service.

SRT Quality Bitrates•The default quality settings for a 1080p/29.97 project are 5-15 Mbits/sec for low, 10-30Mbps formedium and 30-80 Mbps for high. Bitrates will vary, and might exceed the average values, basedon the media being sent over SRT. Bitrates are scaled based on the frame rate and raster size, andmay vary in the actual bitstream based on how efficiently the codec can compress the frames.

•Only 8b quality is supported with SRT. Media Composer will automatically set the I/O to 8bquality if Media Composer is set to draft or 10b.

Projects and Media Support:•2K/UHD/4K projects will be downconverted to HD formats at the same frame rate. For example,
if you are working on a UHD 4k 23.976 projects, it will be converted to an HD 23.976p project.

•Interlaced formats are not natively supported, but will be converted to progressive format at theequivalent frame rate.

•

SRT will mix multi-channel audio to stereo audio.

•RGB is not natively supported and will be converted to YUV.

SRT plug-in is supported with Media Composer | Enterprise and Media Composer | Ultimaten Thelicenses only.

n Currently, audio scrubbing is disabled when broadcasting SRT or with NDI.
To work with the SRT plug-in:

1. Right click on the HW/SW button.
A context menu opens listing the available HW/SW plug-ins.

2. Select Configure.

Open IO Support for SRT

Use the following table to configure the SRT plugin.
ProtocolParameter

Description

SRT

Stream NameYou can provide a custom name for the stream

Mode

To establish a link between a source and destination device,
ensure that one device is a listener and the other is a caller.
The device you set as the caller or listener is arbitrary in mostcases. If the destination device is going to be ingesting
multiple SRT sources, then it must be configured as a listenerand Media Composer must be configured as a caller.

IP Address

The IP address of the destination SRT device.

PortThe port used between the destination and source SRT
device. If you are using SRT on a network protected with arouter and firewall, you may need to configure the router tosupport port forwarding for whatever port you specify.

Password

The password used by both the source and destination toencrypt the stream. You will need to note the password you
use and provide it to the user at your destination.
will receive a warning if you do not setup an Youpassword.

Latency

SRT provides high-quality, low-latency streaming acrossunreliable internet connections. If packets are lost in transit, arequest to re-transmit is sent back to the host. If the host still
has the packet, it will re-transmit. If not, then the packet islost and video and audio may be dropped. If you find that you
are seeing dropped audio and video, increasing the latency
will provide better quality of service but will also increase thelatency between the sender and receiver.

Quality

Specifies the target AV bitrate used for streaming.
High = 30-80 Mpbs

Medium = 10-30 Mbps

Low = 5-15 Mbps

Bitrate above is per 1080p/29.97 and scale proportionally forother formats.

3. Once you have configured the plugin, make sure to select the SRT plugin from the context menu.
A check mark appears next to the plugin when it is selected.
4. Click on the HW/SW button to start broadcasting.
