EDID MANAGEMENT
External EDID Management
The
8x8 Crosspoint Matrix for HDMI
features EDID Management. Before the
I
source can send video or audio signals, the source device reads the EDID
(Extended Display Identifi cation Data) from the output devices connected to the
8x8 Crosspoint Matrix for HDMI
. The EDID contains information about what type
of audio/video data that the source can send to each output device.
The following EDID features are copied from Output A:
•
Supported Resolutions
•
3D Support
•
Audio Features
Display Connections:
•
If a device is not connected to Output A, then no EDID changes are made,
meaning that the previous EDID information will be used. This state will be
in effect until a display is connected to Output A and the Matrix is power-
cycled.
•
EDID is built from Output A to the Input. The audio block will be copied
from Output A. EDID-copying is performed only when the Matrix is reset or
power-cycled.
