the various input signals:
GENERAL USE
In use, the X-DVIPRO-DL modules should be transparent - the system and its
peripherals should operate exactly as normal, the only difference being that they are now
up to 50 meters apart.
Video display (EDID) information
ExtendedDisplayIdenticationData(orEDID)isanindustrystandardschemewhich
allows video displays to declare their capabilities to the computer’s video adapter
circuitry, allowing the latter to optimize their outputs accordingly. Since the widespread
adoption of the scheme, video adapters have become increasingly dependent on receiving
relevant EDID information during start-up, before they will output anything more than a
rudimentary video signal.
Each time that the remote module is powered on, it attempts to read the EDID
information from the connected DVI video monitor. If the attempt is successful, the
information is transferred to the local module and stored within non-volatile memory.
This information is then made available to the computer’s video adapter when required.
HDMI 1.3a operation
Using optional HDMI to DVI converter cables (Adder part number: VSCD11), the
AdderLink X-DVIPRO-DL can support HDMI video and audio up to the 165MHz clock
rate (1920 x 1080 at 60Hz, 24-bit color).
Eight channels of HDMI audio are supported with sample sizes of 16, 20 or 24-bits at
32KHz,44.1kHz,48kHz,88.2kHz,96kHz,176.4kHz,or192kHz(simultaneouslywiththe
jack audio).
Note: The High-bandwidth Digital Content Protection (HDCP) and Consumer Electronics Control
(CEC) schemes are not supported.
