EDID MANAGEMENT
External EDID Management
The 8x8 Crosspoint Matrix for HDMI 1.3 features EDID Management. Before
the 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
Splitter. The EDID contains information about what type of A/V data that the
source can send to each output device.
The 8x8 Crosspoint Matrix for HDMI 1.3 routes multiple sources to multiple
output devices. This involves reading EDID data from more than one device.
Management of the EDID data is important to maintain compatibility between all
devices.
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.
