Live Video Broadcasting over Bonded 4G LTE and 5G

Choose the transport and production equipment

Portabella can use the optional Streamer software add-on for live video optimization. Streamer PRO and Teleporter are End-of-life historical designs; they are not the current embedded-modem Streamer models. Compare the current family brochures.

Set up the complete broadcast path

1. Verify the encoder and destination. Confirm the video/audio format, bitrate, stream protocol, destination URL and any stream credentials against the chosen server/CDN and relay service.
2. Bring each WAN online. Activate and test each cellular or wired path independently. Check antennas, carrier plans, wired WAN addressing and available uplink capacity.
3. Connect the encoded stream. Connect the encoder/switcher through the supported Ethernet or Wi-Fi input. Keep the encoder and transport LAN settings consistent with the supplied configuration.
4. Configure and verify the video relay. Confirm the Streamer-to-relay connection and the relay-to-destination path. The Streamer VOM reference uses “Connected to BPA: YES” as a connection check; use the applicable firmware/status view.
5. Select the bitrate and delay policy. Leave adequate usable uplink capacity for the stream and transport overhead, including the expected surviving paths. Set the play-out delay for the acceptable production latency and path variability.
6. Validate at the receiver. Observe the stream at the actual CDN/player or studio endpoint, checking audio/video sync, continuity, delivered bitrate and end-to-end delay.

Understand adaptive transport, capacity and latency

Video Armor uses the relay and its buffering/transport configuration to handle the encoded stream over changing WAN paths. The bonding algorithms adapt path use as capacity, delay, loss and outages change.

A larger permitted play-out delay can provide more time to handle path variation, at the cost of added production latency. The older support reference explains that a sender delay approaching or exceeding the configured play-out delay can produce an uneven output stream. Use the values approved for the exact model, firmware and production workflow.

If usable uplink capacity falls below the stream’s needs for too long, reduce the encoded bitrate or revise the connection mix and delay policy. Total path loss, relay unavailability or a failed encoder/CDN can interrupt the production; the transport is not a guarantee against every failure.

Rehearse the production before going live

• Record the transport model, modem/carrier mix, firmware, encoder, codec, protocol, bitrate, relay, play-out delay and receiver/player.
• Run a representative stream for the planned production duration and monitor both the transport and receiving endpoint.
• In a test setup, disconnect a WAN and introduce reduced capacity, loss or changing delay. Observe receiver continuity, sender/play-out delay and the bitrate supported by the surviving paths.
• Test competing network traffic, encoder restart and relay/destination reachability, with the expected recovery procedure documented.
• For a studio workflow, confirm the receiver/decoder, audio/video format and end-to-end production latency.
