Getting ready - AWS Elemental Live

Getting ready

Before you create a Zixi output in your event, perform the following preparation.

  • Speak to the administrator of the downstream system and make sure that they can work as the Zixi receiver. If they can't, then you can't deliver using the Zixi option.

  • Decide if you want to deliver redundant streams in the output. Each stream has a different destination on the downstream system. The downstream destination initially handles one stream. If that stream fails, the downstream destination can switch to the other stream.

    You should find out if the downstream destination can handle this type of resiliency. If they can't then there is no point to delivering two streams.

    If you do want to deliver two streams, you must make sure that your content provider can send you two copies of the source. The two copies must be completely identical.

  • Decide if you want to encrypt the content. If you do, discuss the following with the downstream destination:

    • Discuss the encryption level with the administrator of the downstream system. Both sides must use the same level. You can use AES 128, AES 192, or AES 256. You should provide this information to the downstream destination so that they can set up with the same level.

    • Agree on an encryption key value. The value is an ASCII representation of hexadecimal bytes. The length must be correct for the encryption level. For example, for AES 128, it must be a 32-character string of 16 hexadecimal bytes.

  • Discuss the following with the administrator of the downstream destination:

    • Obtain the IP address and port for each destination for the output. For example, 198.51.100.0:2088.

    • Make sure that the administrator of the downstream system sets up to allow Elemental Live to access the destination. For example, they might need to open ports on the destination, or allow traffic from the public IP address of Elemental Live.

    • Tell the downstream destination the latency (in milliseconds) that you plan to configure into Elemental Live for packet loss and recovery. Packet recovery is a key feature of Zixi. The downstream destination should choose a latency value that is close to the value that you plan to use.
