 OTT Protocols: OTT (Over-The-Top) Protocols are HTTP Live Streaming and RTMP.
Licenses in this column are applicable to both protocols. Each instance of either protocol
requires a license. OTT licenses are provided at no cost, please contact support@Niagara
Video.com with your encoder serial number if you would like to enable these protocols.
However, please note that RTMP only supports AAC-LC audio; the encoder must have
AAC-LC licenses to run RTMP. The HLS protocol does not require AAC-LC, but many
mobile devices that support HLS only work with AAC-LC. This is the case for most
Apple devices.
 SMPTE 2022 FEC: This enables FEC for the board. This is not a counted feature; if
FEC is enabled, the corresponding number is 1; if it is disabled, the corresponding
number is 0. The Used Licenses field will be set to 1 if there is at least one FEC instance
in use.
If you want to request a license key from Niagara Video, you will need to provide the card serial
number. It can be found in the Product Tab and in the Admin License Key Tab as well. Once
you receive the key from Niagara Video, enter it in the License Key field shown above, and
click on the Apply License Key button. If the key is accepted, you will see the message License
Key Installed OK, as illustrated above. If there are any problems, you will see an error message
in the same location. The following are the possible error messages:
 Invalid key: missing characters: the key you entered is too short. Double-check that you
entered all the characters. Make sure to press ENTER after entering the key.
 Invalid/Corrupted Key: the key you entered has the correct number of characters, but it is
invalid. Double check what you entered.
 Serial number mismatch: this key is for serial xxxxxxxxxxxx: B264 license keys are
specific to a card. You entered a valid license key, but it is intended for a different card,
whose serial number is displayed in the message. You must use this key on the correct
card.
 This key has already been applied: License keys can only be applied once. This is a
valid key for this card, but you have already applied it, and its features are already
available.
