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
®
undesired decoder or interrupting other non-Enterprise AV network devices.

Enterprise AV is different from traditional fixed-chassis video matrixing systems (ie 4x4, 8x8,
16x16). For each video source/input, add an Encoder unit. For each video display/output,

add a Decoder unit. Up to 1024 encoders can be integrated with an unlimited amount of
displays.
For example, if your system requires 4 video sources to be distributed to 42 displays, you
may build a system using (4) KD-IP9222ENC, (42) KD-IP9222DEC, and the appropriate
IGMP network switch.
You must ensure that all units are fully configured before connecting all units to your network
switch. Refer to the Unit and System Setup using KD Wizard Utility section for more
information.
