CASTER TRANSPORT · BROADCAST-GRADE INTERNET

Replace satellite links with
sub-second broadcast transport.

Caster Transport uses SRT and WebRTC to deliver broadcast-grade HD and UHD video over the public internet. Sub-second end-to-end latency, 4K quality, packet-loss resilience on unstable networks, AES-256 encryption. Push simultaneously to YouTube, Facebook Live, and self-hosted CDNs — and put the SNG truck back in its rack.

WHY NOW

From SNG trucks and SDI runs, to SRT + WebRTC over public IP,
this is the engineering shift for live contribution.

Remote contribution means SNG trucks; live events mean leased fiber. Equipment is expensive, channel fees are monthly, and adding a venue means re-trucking and re-cabling. Caster Transport moves contribution onto the public internet: SRT recovers from packet loss without dropping frames, WebRTC crosses network boundaries in real time, AES-256 turns every packet into a sealed envelope. One server, many streams, every platform.

LEGACY · SATELLITE CONTRIBUTION

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.

CASTER TRANSPORT · POINT MEDIA TECH

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 spin up in minutes, not days.

CAPABILITIES · THREE LAYERS

Three capability layers, threaded into one
low-latency transport chain.

Transport protocols → multi-platform distribution → system integration. Each layer can be evaluated independently, licensed by stream count, and scaled later.

i.

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
ii.

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
  • Auto-reconnect on failure
iii.

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.

  • REST API + webhook
  • Playout / Encoder integration
  • Multi-user permissions
  • Dashboard and logs

WORKFLOW

Caster Transport is the last mile to the audience,
moving live signal to every platform.

From camera to viewer screen, Caster Transport replaces SNG trucks, leased fiber, and CDN encoders — one server end to end.

HOW TO START

Three steps, from evaluation to go-live.

i.

Request a trial

Submit the contact form. Our sales team responds within one business day and schedules an assessment with a solution architect.

ii.

Integration assessment

Our solution architects review your existing sources and destination platforms, and plan the connection points to Encoder / Playout / Master Control.

iii.

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.

FAQ

Frequently asked questions.

Which streaming protocols does Caster Transport support?

Caster Transport supports SRT, RTMP, HLS, and WebRTC, and can push simultaneously to YouTube, Facebook Live, self-hosted CDNs, and other destinations — covering both contribution and distribution workflows.

What are the concrete advantages of Caster Transport versus traditional satellite contribution?

Caster Transport replaces satellite links with internet transport, delivering sub-second end-to-end latency and AES-256 encryption. Operators typically reduce equipment and channel rental costs by more than 90% compared to satellite contribution.

Can Caster Transport integrate with our existing broadcast systems?

Yes. Caster Transport exposes standard APIs that integrate with Kaster Playout, Broadcast Encoder, and Master Control, enabling one-click, multi-platform simultaneous push from the same source.

How is Caster Transport licensed?

Caster Transport is licensed by the number of outbound streams and destination platforms, with flexible tiers. Contact a sales consultant for a detailed quote matched to your actual contribution and distribution needs.

What system requirements does Caster Transport have?

Caster Transport runs on standard server hardware and supports Linux and Windows. Exact specifications depend on stream count, resolution, and destination platforms — our solution architects will help size the right configuration.
