OnPremise SRT Server by StreamRus is commonly deployed in IPTV and cable headends to manage contribution and distribution of live video over IP networks using SRT and UDP.
This page lists typical broadcast workflows where an on-premise SRT gateway is required.
Problem
An operator needs to receive live feeds from remote locations over the Internet and inject them into a local IPTV headend.
Why SRT
SRT provides encrypted, low-latency and packet-loss-resilient transport over unmanaged networks.
How OnPremise SRT Server fits
OnPremise SRT Server by StreamRus receives incoming SRT streams and forwards them locally as UDP unicast or multicast to encoders, multiplexers or IPTV middleware.

IPTV Headend (UDP unicast/multicast)
Problem
A single live feed must be distributed to multiple remote sites (regional headends, affiliates, monitoring locations).
Why SRT
SRT allows secure distribution over WAN links without multicast.
How OnPremise SRT Server fits
The server acts as a central SRT gateway, receiving one input and replicating it to multiple SRT outputs.

Problem
UDP multicast cannot be transported reliably across WAN/Internet links.
Why SRT
SRT replaces multicast with encrypted unicast transport, keeping low latency.
How OnPremise SRT Server fits
OnPremise SRT Server converts local UDP multicast streams into SRT for WAN distribution, and can restore them as UDP multicast at the destination.
Problem
Contribution and distribution networks must be isolated for security and operational reasons.
How OnPremise SRT Server fits
The software supports multi-NIC and VLAN-based deployments, enabling separate networks for input and output traffic.
Problem
Broadcast environments require deterministic behaviour and continuous operation.
How OnPremise SRT Server fits
Designed for on-premise deployment, the server integrates into headend monitoring and operational workflows.
