HDMI
Revision
1.3a + ARC. ARC (Audio Return Channel) imple-
mented per HDMI 1.4a
Device Connections
SOURCE Typically connects to the sink input of
a DUT.
The video is an internally generated sin-
gle color screen or the signal applied to
the AUX IN connector. The audio is
internally generated: see “Embedded
Output Signal Related” under “DIGITAL
I/O” for typical waveforms and parame-
ters.
ARC Tx / AUX IN HDMI ARC Tx configuration: Typically
connects to an HDMI source that
accepts ARC audio.

ing device.
HDMI ARC Rx configuration: Receives
and analyzes audio across ARC, per
HDMI 1.4a. No video is transmitted.
HDMI Sink configuration: Contains video
and audio sent to Sink input.
SINK Typically connects to the source out-
put of a DUT.
The embedded and encoded audio sig-
nal components are recovered for analy-
sis.
Hardware Interface
