Configuration method
Multicast
Multicast is especially useful for use-cases that require a single source to be received on multiple receivers simultaneously.
Utilising Muliticast offloads the distribution of the NDI A/V packets from the BirdDog Flex 4K to the network infrastructure. You
should take care to ensure your network is specifically configured to support Multicast as using it on an ill-prepared network can
create unintended network problems.
MultiTCP
MultiTCP is a new NDI transport method that allows users to send NDI video over poor network topography such as WAN (Wide
Area Networks) without experiencing issues such as packet loss and lost frames. In the past in order to send NDI video over a
WAN the UDP transport was the only option available. UDP solved some issues of WAN applications by allowing the NDI video
to travel without dropping masses of frames but results in dropped packets being missed which could cause unstable video. UDP
also places more performance demands on devices sending and receiving the signal.
MultiTCP employs a new method of sending TCP packets whereby it opens a mass of TCP connections over the WAN and uses
them in a ‘round robin’ manner, this allows each individual TCP connection enough time to acknowledge the receiving packet,
confirm nothing is lost and prepare for the next one before it’s sent the next TCP packet in the round robin. This is similar to a
RAID setup in traditional storage.
OPERATION
Factory resetting your unit
If you have lost any network settings or cannot find your BirdDog Flex device on the network, you can perform a network factory
reset.
Simply depress the reset button located next to the RS-232 port for 5 seconds until the Halo tally illuminates flashing red. The unit
will be accessible as per factory settings approximately 10 second later.
