EDID Control
EDID (Extended Display Identification Data) is a data structure that is used between a display and a source. This data
is used by the source to find out what audio and video resolutions are supported by the display device. From this
information the source will discover what the best audio and video resolutions need to be output.
In a normal matrix based system, issues can arise when multiple displays or video matrix switching is introduced
because of the increased number of variables.
In the Blustream Multicast system each source device only communicates with a single Blustream IP50HD-TX
Transmitter meaning there is only a single EDID handshake. As each Blustream Multicast IP50HD-RX Receiver has its
own in-built video scaler, it is advised that the source EDID is set to output the best video signal possible as this can be
down-scaled (as required) at each IP50HD-RX Receiver.
Configuration of Multicast EDID settings can be achieved in several ways:
1)
During the manual configuration of the IP50HD-TX Transmitter - see previous pages
2)
Using the Multicast Web-GUI interface (by addressing the unit via it's IP Address within a browser)
3)
Using the Web-GUI of the Blustream ACM200
4)
Using RS-232 commands via the Blustream ACM200
When configuring the EDID during manual setup, or using RS-232 commands the following table indicates EDID values:

The Blustream IP50HD products only support 2ch audio signals. The available EDID options
therefore only allow for 2ch audio formats.
