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 IP250UHD-TX
Transmitter meaning there is only a single EDID handshake. As each Blustream Multicast IP250UHD-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 IP250UHD-RX Receiver (max 4K 60Hz 4:2:0 or 4K 30Hz 4:4:4).
Configuration of Multicast EDID settings can be achieved in several ways:
1)
During the manual configuration of the IP250UHD-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 IP / 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:

Please note:
The Blustream Multicast products do not down-mix Dolby Digital, DTS or 5.1ch audio signals. Should
the end-points (displays) only support 2ch PCM, or Dante audio features are used, set the EDID value to match audio
formats supported throughout the system.
