    4 Hardware Streambox Chroma is available in 3 main models: HD, UHD, and 4K, with some additional upgraded versions such as the 12G-SDI version, available. Furthermore, each of the 3 models is available in an Encoder version and a Decoder-only version. The Encoder versions can be switched into Decoder mode, in a half-duplex fashion: the unit can be anEncoder or a Decoder, but not both at the same time.

    5. After saving the MSK value, press the Down arrow again to set the Default Gateway, which is the address the Streambox will use to reach outside the network. Edit and Save this value as above. 6. Press Down again, and you should see either SET STATIC or CHANGE STATIC, depending on whether there’s already a static value saved.
  • Page 37 Sending Live Streams (Point-to-Point) (1770/UDP) Streambox Encoders and Decoders can send live streams over private or public IP networks. The Decoder’s IP address is fed into the Encoder’s settings so it knows where to send the stream; the Decoder’s replies and acknowledgements are sent back to the Encoder (LDMP protocol).

  • Page 38: Network Ports

    52.66.83.26 Central Asia (India) Streambox Cloud is multi-tenant service; each Decoder setting for the Cloud can be configured for specific “destination” port number, with default port UDP 1770 . Streambox Cloud will use random source port number when routing stream to remote Decoder, so ​ t he firewall rule should not restrict traffic based on source port number, but can restrict traffic based on destination port number and Source IP.
