The examples below show some uses for the insertion/extraction functionality on the AIE Board.
Individual connectors on an AIE Board can be set to insert or extract audio onto/from their numerically
corresponding standard inputs/outputs.
AIE Board in Left AIE Slot – Extract Function
Extracted audio remains intact from standard input to standard output but is also sent on to an auxiliary
audio system for further distribution.
AIE Board in Left AIE Slot – Insert Function
Inserted audio is received separately from PC source, embedded onto the HDMI signal, and routed from
standard input through standard output(s) to destination(s) as an HDMI signal with embedded audio.
AIE Board in Right AIE Slot – Insert Function
Inserted audio from auxiliary audio system replaces embedded audio on HDMI signal and is sent to the
