AUDIO BREAKAWAY AND EMBEDDING

PROBLEM – ACCESSING EMBEDDED AUDIO ON HDMI

HDMI inputs integrate audio and video into the same cable. Unfortunately, embedded audio provides an

added layer of difficulty when dealing with most installations. Because audio is embedded within the

video stream, there is no way to access the audio directly for use in other locations than where the

displays are located. Additionally problematic is the need to integrate audio over a digital input which

doesn’t yet have embedded audio (DVI from a computer) and must be routed through the common

distribution system.

Both issues have traditionally required extra converters, extractors or embedding devices, which involve

set-up, extra space and cabling hassles either before or after a centralized matrix switching system. But

these issues have been eliminated with the Enova DGX 16/32 Audio Insert/Extract board.

AMX SOLUTION – AUDIO INSERT/EXTRACT BOARDS

The Audio Insert/Extract board allows integrators to access embedded HDMI audio from local or

distance transport inputs or outputs and can be set up to provide insert or extract functionality on a per

channel basis. The board is loaded in either the input or output side expansion slot and does not reduce

the overall matrix size through its use. For even greater flexibility, an Audio Insert/Extract board can be

loaded on both input and output sides to access both inputs and outputs simultaneously. This solution

greatly increases the usability and access of embedded audio without requiring extra audio

strippers/extractors either before or after the matrix switcher.

The illustrations show options to embed or de-embed audio from various sources to various outputs.

INSERTING AUDIO TO A DIGITAL VIDEO ONLY SOURCE TO PROVIDE HDMI WITH EMBEDDED AUDIO

OUTPUT (SOURCE SIDE - AUDIO INSERTION)

This design allows a separate audio source from the PC to be embedded with the video source and sent

over a single HDMI cable to the display:
