BeStream Edge

Reliable Contribution Transport Protocol

Secure contribution transportfor unstable IP environments

BeStream Edge is a contribution transport protocol built for moving live video between field encoders, control rooms, studios and monitoring points over public or private IP networks. It combines authenticated encryption, adaptive packet recovery and operational monitoring in a sender/receiver workflow designed for real broadcast use.

Why engineering teams choose it

A protocol-first approach for reliable live video transport

BeStream Edge focuses on contribution-grade delivery over IP with encrypted packet transport, configurable recovery behaviour and clean sender/receiver operation on Windows or Linux. It is designed for broadcast and operational workflows where packet loss, jitter and route instability must be managed without losing the signal.

Protocol overview

One protocol layer. Encrypted transport, resilient delivery, operational control.

BeStream Edge runs as a lightweight sender/receiver service on Windows or Linux. Fully controlled by your team and deployable on private infrastructure.

Secure Transport

Move live contribution feeds across public, private or restricted IP paths with authenticated protection on each transport packet.

Authenticated encryption on every packet
Replay and tamper resistance at the transport layer
Suitable for public internet, VPN and private routing

Resilient Delivery

Adaptive FEC and ARQ recovery help sustain contribution feeds on lossy, jittery or operationally difficult links.

FEC for immediate recovery without always waiting for retransmission
ARQ support for burst-loss conditions
Configurable bitrate, latency and recovery profile

Operational Fit

Designed for real broadcast contribution workflows with deployable sender/receiver nodes and browser-based control.

Browser UI for channel and key management
Windows service or Linux daemon operation
Live bitrate, RTT, FEC and recovery visibility

Signal flow

Contribution transport in four stages

Any encoder or media source sends UDP into BeStream Edge. The TX applies transport protection and recovery settings, sends across the network, and the RX reconstructs and outputs the signal for local use.

Input: UDP from encoder or media gateway. Codec-agnostic contribution workflow.

Transport: BeStream Edge protocol with authenticated encryption, FEC, ARQ and adaptive transport behaviour over UDP.

Output: Clean UDP or RTMP for local media systems, monitoring or onward distribution.

Management: Browser-based channel setup, transport keys and live protocol telemetry.

Deployment path

Deploy sender and receiver

Run the same protocol stack on both ends as a lightweight Windows or Linux service.

Connect the source

Feed UDP from your encoder or upstream media device into the sender node.

Set transport profile

Choose encryption, recovery, bitrate and latency values based on the target network path.

Deliver at the far end

The receiver reconstructs the stream and outputs it to local broadcast or monitoring infrastructure.

Use cases

Built for contribution workflows that cannot rely on a perfect network

From broadcaster field contribution to difficult fixed-location paths, BeStream Edge is intended for situations where operational continuity matters more than ideal network conditions.

Transport behaviour

Recovery and continuity at the protocol layer

BeStream Edge is designed to improve contribution continuity by combining encrypted transport with adaptive recovery techniques. The aim is operational stability, controlled latency and better tolerance to packet loss on imperfect IP paths.

Control

Protocol behaviour that matches contribution requirements

Instead of relying on a single recovery method, BeStream Edge combines authenticated encryption, parity-based forward recovery and retransmission logic in one transport path. This gives operators more control over how bitrate, latency and resilience are balanced per link.

Packet recovery

Contribution transport that keeps the signal moving

BeStream Edge monitors packet loss and uses recovery mechanisms before damaged transport conditions turn into visible operational disruption downstream.

Recovery data travels alongside contribution traffic

✓ Receiver reconstructs the missing packet and the feed continues

Recovery data travels alongside contribution traffic. When loss conditions allow it, the receiver reconstructs missing packets without waiting for a full retransmission cycle. When needed, ARQ adds another recovery path for burst-loss events.

Difficult contribution paths where continuity matters most

Works quietly on difficult links

Recovery capacity can be tuned to match expected network conditions, from stable managed paths to more volatile public internet contribution routes.

Two recovery paths

If a packet is recoverable through parity, the receiver restores it immediately. If loss conditions exceed that layer, retransmission provides another recovery chance.

Operator control

Latency and recovery are not fixed assumptions. Operators can tune them to the path, bitrate and operational priority of the feed.

Protocol stack

A transport stack designed for live contribution

The protocol combines encryption, recovery and packet delivery behaviour in one transport layer so operators can control resilience without adding unnecessary workflow complexity.
