What is Zixi?

Zixi’s software platform enables the delivery of flawless, broadcast-quality HD video over the Internet, in real time to any device over any distance. Based on Zixi's low-latency, distance-agnostic protocol, the platform includes end-to-end components that deliver video with unprecedented quality regardless of network conditions.

 

How to use Zixi

Using Zixi is very similar to the other streaming outputs on Videon devices. For the most part, all that is needed is a properly constructed URL. Zixi has a couple additional options, which are explained below.

  1. Navigate to Encoder Control > Outputs > Zixi 1, 2, or 3
  2. Enter the URL of the receiving end and a port. The default port is set to 2088. The URL may be an IP and port combination or a host name, depending if the ingest is a Point-to-Point decoder or an online streaming platform.
      1. The port should match on the sender (Videon device) and receiver (ingest/decoder/server)
  3. Enter the Stream ID if applicable. Some servers that accept Zixi require Stream IDs to be used in order to ingest multiple Zixi streams at the same port
  4. Set the Max Latency value
    • This value represents the duration of content that is buffered to allow for re-transmission of data (that is how Zixi is reliable). This is not the expected glass-to-glass latency
    • The lower the latency, the less reliable. The higher the latency, the more reliable the stream will be
  5. Set the FEC Percentage (Forward Error Correction) value
    • This value represents the reserved/allowed bitrate/bandwidth overhead for FEC packet (re)transmission
    • We allow setting up to 50% FEC Percentage value
  6. (Optional) Set the passphrase
    • The passphrase allows the Zixi stream to be passphrase protected
  7. (Optional) Set the encryption key and key size
    • Encryption allows the Zixi stream to only be accessible to a receiver that has a matching encryption key and key size set. This allows a stream using Zixi to ensure only the right receiver is decoding the stream.
    • The larger the encryption key, the more secure
    • An encryption key can be generated from the Videon Web UI by clicking Generate
      The following pop-up will then display:
      EncryptionKey.jpg
    • You can then select Use Key and this will be the encryption key used in the Zixi stream. It is also recommended to select Copy Key to make note of the encryption key if needed elsewhere
  8. Once everything is set, enable Zixi, select Save, and check if it is being received by the other end of the workflow!
