Debonding Decoder License

Updated on

What Does It Do?

The Debonding Decoder license allows users to receive a stream via a built-in Hyperion server (used for Teradek Bonding Protocol), decode that stream to SDI or HDMI, and re-stream further on.  It can also ingest generic streaming protocols to decode and send on.

What Is It Used For?

The license is primarily used when a cloud connection is unavailable or not desired.
For example, bonding across multiple connections from a roaming camera with a Prism Mobile back to a decoder in a small market TV station.

Additionally, there might be situations where one needs to ingest a third party encoding or PTZ stream and forward that stream onto a bigger platform over an internet connection.

Supported Input Protocols

The Debonding Decoder supports the following ingest types which will be passed onto the decoder

  • Teradek Bonding Protocol (Most used)
  • RTSP
  • SRT
  • RTMP
  • HLS
  • File ingest from SD card or NFS

Supported Output Protocols

The Debonding Decoder supports the following outbound types

  • Teradek Bonding Protocol
  • RTSP
  • SRT
  • RTMP
  • HLS
  • Airmix (TDS)


  • Prism Flex Decoder or Prism RU Decoder
  • Debonding Decoder License
  • A navigable public IP or a firewall that supports port forwarding when used with the public internet.
  • Teradek Bonding Protocol - port 5111 TCP/UDP. All others are declared in the configuration UI.

Contact your IT department for assistance with firewall configuration.

Setup the Debonding Decoder

This is the standard setup process for the Teradek Bonding Protocol over the public internet, assuming that your network requirements are in sync.

1. Navigate to the IP address of the Prism Flex or Prism RU decoder to open the decoder web UI.
2. From the decoder’s web UI, open Licenses and click the Enter License Key tab to enter the Debonding Decoder license key. If you don't have a license, please contact [email protected].

3. Open the Ingest tab above and set the Ingest Mode to Hyperion.

4. Scroll down and click + Add Ingest, then choose Teradek Bonding from the Stream Ingest options. Next, configure the Prism Encoder to transmit to the Debonding Decoder (see below). Once the video signal is live, choose the encoder via its serial number from the Device List to set up the Device ID. If you have set a password on the encoder, enter it in the Password field. When done, click Save to complete the process.

5. To output the stream to a specific destination, click + Add Stream under the Hyperion Output section.

6. Click the Scroll-down icon and select a Stream Mode. Click Save when done.


  • Teradek Bonding - Select this mode to stream to Core or another Hyperion Server (uncommon)
  • MPEG Transport Stream - Prism sends video via a TCP or UDP protocol to a specified unicast or multicast address.
  • SRT - Transmit high-quality, low-latency video over unreliable networks to a single destination IP address on a specific port. A port number and a passphrase (if encryption is enabled) are needed.
  • RTSP - Prism sends video via a TCP or UDP protocol to a specified IP address. Ensure you have the correct port and stream name (stream1 is the default).
  • HLS - Creates an HLS pull server that can be viewed in a web browser.
  • Airmix - Stream to device using the Airmix app (port default is 2020). NOTE: The Decoder and the device running Airmix must be on the same WiFi network.
  • Preset - Select a preconfigured Channel Preset from the Preset list below. NOTE: You must first configure a preset and/or account (if outputting to a streaming platform) before selecting this option.
    • Preset Streaming Options:
      • MPEG Transport Stream
      • SRT
      • RTSP
      • RTMP
      • Streaming Platforms - Facebook, Youtube, Vimeo, etc (you must first configure an account in the Accounts window below Channel Presets)

7. Click Save when done.

Setup the Encoder to Stream to the Debonding Decoder

1. From the encoder’s web UI, open the Input/Encoding tab and set the Stream Mode to Teradek Cloud.

2. Enter the details

  • Host: Public IP (whether port forwarded or not)
  • Port: (Default 5111) or if your public port forwarded port
  • Session Password (Optional):  Must match on the Debonding Decoder, if used
  • Buffer length:  the amount of delay in the Debonding Decoder to allow multiple connections to arrive.
  • Adaptive Bitrate: allows Teradek Bonding Protocol to adapt the bitrate of the stream to the entire network bond.
  • Encryption (Optional):  Encrypts Teradek Bonding Protocol with AES-128

3. Click Save and the encoder will start to stream video.
