Considerations and Preparations
Technology Overview:
Key Digital’s Enterprise AV over IP products enable distribution, switching, and extension
of HD Video and other media using managed network switches as the central hub of the
system.
Enterprise AV utilizes multicasting technology to broadcast (encode) the source media (ie HD
video, audio, IR and RS-232 control, USB) to connected
network devices. Decoders receive the desired source by
setting a Group ID that corresponds with the ID of the desired
encoder.
The network switch must support IGMP v2 (Internet Grouping
Management Protocol) and 8K Jumbo Frame in order to
prevent a broadcasted signal from being received at an
undesired decoder or interrupting other non-Enterprise AV network devices.
