External Edid Management

EDID MANAGEMENT

The 4x2 Switcher for HDMI 1.3 features EDID Management. Before the source can send video or audio signals, the source device reads the EDID (Extended Display Identiﬁcation 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 4x2 Switcher for HDMI 1.3 distributes a single source 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 1:

•Supported Resolutions

•3D Support

•Audio Features

EDID color features are built based on all attached displays, using the following rules:

•Deep Color will be enabled if one or more displays are connected to the Splitter supporting Deep Color.

•xvYCC (x.v.Color) is supported if all connected displays support it.

Display Connections:

•If a display is not connected to Output 1, 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 1 and the Splitter is power- cycled.

•EDID is built from Output 1 to the Input. The audio block will be copied from Output 1. EDID-copying is performed only when the Splitter is reset or power-cycled.
