Replace satellite with SRT ·
broadcast transport over the public internet.
Point Media Tech's Caster Transport is an SRT internet transport system: it carries broadcast video over the public internet with SRT and WebRTC, replacing SNG trucks and leased fibre. 4K broadcast quality, sub-second end-to-end latency, SRT packet recovery on unstable networks, AES-256 encryption. One feed pushes to YouTube, Facebook Live and self-hosted CDNs at once, and the transport kit fits in a server rack.

Zero frames lost on air.
Caster's transport monitor shows link packet loss and on-air frame loss side by side. The amber spikes are packets SRT retransmitted inside the latency budget, and below them one feed fans out to five destinations across four protocols.
From SNG trucks and leased fibre, to SRT + WebRTC over public IP,
the cost model of live contribution changes.
Caster Transport moves remote contribution and live events from SNG trucks and leased fibre onto the public internet, so an added fixture no longer waits for a circuit. The legacy route means expensive kit, monthly channel fees and mobility tied to hardware; Caster uses SRT packet recovery, WebRTC network traversal and AES-256 encryption, so one server handles many streams to several platforms.
SNG trucks, leased channels, fiber runs
Each SNG dispatch is a major line item; satellite channels billed monthly; cross-region fiber priced by distance; equipment moves and setup take hours; multi-platform delivery means multiple devices; mobility constrained by hardware location.
SRT recovery, WebRTC traversal, AES encryption
Public-internet SRT recovers lost packets without dropping frames; sub-second end-to-end latency; 4K broadcast quality; AES-256 encryption; one server pushes to YouTube, Facebook, and self-hosted CDN simultaneously; new venues can be added at short notice.
Today · Satellite trucks and leased fibre
- Remote contribution rides a satellite truck
- Live events depend on leased fibre
- Expensive kit, high circuit costs
- Adding a fixture at short notice is painful
After · SRT and WebRTC over the public internet
- SRT recovers packets without dropping frames
- WebRTC is immediate across networks
- AES-256 encryption on every packet
- One server, many pushes, several platforms at once
Three capability layers, threaded into one
low-latency transport chain.
Caster Transport works in three layers: transport protocols, multi-platform distribution and system integration. Each layer can be evaluated independently, licensed by stream count, and scaled later.
Transport protocols and low latency
SRT recovery preserves packet integrity; WebRTC enables real-time cross-network transit; HLS / RTMP for compatibility; AES-256 end-to-end encryption; broadcast quality holds even on lossy networks.
- SRT / WebRTC / RTMP / HLS
- End-to-end latency < 1 s
- AES-256 encryption
- Packet recovery / FEC
Multi-platform simultaneous distribution
One source, simultaneous push to YouTube Live, Facebook Live, Twitch, and self-hosted CDN; independent bitrate and resolution per destination; live status monitoring; auto-reconnect on failure.
- YouTube / Facebook / Twitch
- Self-hosted CDN / RTMP server
- Independent bitrate per stream

System integration and management
REST API and webhook into Playout / Encoder / Master Control; live stream status reporting; multi-user permissions; unified dashboard for every route; historical logs and report export.

Caster Transport is the last mile to the audience,
moving live signal to every platform.
Caster Transport sits after the encoder and before the delivery platforms: it takes the Broadcast Encoder output, carries it over SRT / WebRTC on the public internet, and fans it out to YouTube, Facebook and CDNs.

Integration assessment
Our solution architects review your existing sources and destination platforms, and plan the connection points to Encoder / Playout / Master Control.
Deployment and go-live
Complete configuration, run acceptance tests (SRT connectivity, multi-platform sync, encryption verification), and roll out in phases so existing operations are not disrupted.
Frequently asked questions.
Which transport and streaming protocols does Caster Transport support?
Point Media Tech's Caster Transport supports SRT, WebRTC, RTMP / RTMPS, HLS and MPEG-TS over UDP. SRT and WebRTC handle contribution and cross-network transport over the public internet; RTMP and HLS push to YouTube, Facebook Live and self-hosted CDNs.
What actually changes when SRT internet transport replaces satellite?
Caster Transport replaces SNG trucks, satellite channels and leased fibre with SRT over the public internet; a venue needs just an encoder and network. SRT recovers packets with ARQ + FEC, end-to-end latency is under 1 second, and AES-256 encryption is built in. Operators typically reduce equipment and channel rental costs by more than 90% compared to satellite contribution.
Can Caster Transport integrate with our existing Playout, Encoder and Master Control?
Yes. Caster Transport connects to Kaster Playout, Broadcast Encoder and Master Control through a REST API and webhooks, and passes SCTE-35 markers through. Stream status reporting and a unified dashboard let on-duty staff see every destination on one screen.
How is Caster Transport licensed and priced?
Caster Transport is licensed by outbound stream count and destination platforms, as a software license plus annual maintenance. Quotes depend on your actual streaming requirements; contact a sales consultant.
What hardware and network conditions does Caster Transport need?
Caster Transport runs on standard Linux or Windows servers, as a single node or a cluster. Exact specifications depend on stream count, resolution and destinations; uplink bandwidth and line quality at the venue are tested during the assessment.
