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.
