1.3 Advanced Features
With the release of version 4.1.5

, the KXI-DVI-Bridge has two modes of operation:
1) Mode A (Static Content): This is the same functionality as a standard (pre-4.1.5) KXI-DVI-Bridge
(see “Basic Features” above). The KXI-DVI-Bridge always outputs at 1920x1080p @ 29.97 no
matter what the input is. Best for computer-generated text and static graphics.
2) Mode B (Dynamic Content): In this mode, the KXI-DVI Bridge can convert DVI signals entering or
leaving a Kaleido-X.
Input: The upgraded KXI-DVI-Bridge converts DVI signals to 1920x1080p @ 50/60 Hz or 1280x720p
@ 50/60 Hz, suitable for input to a KXI card. The refresh rate is maintained and hence smooth
playback of streaming video or computer-generated animations is possible.
Output: The upgraded KXI-DVI-Bridge converts Kaleido output (specifically preset to 1920x1080p or
1280x720p @ 50/60 Hz) to a corresponding HD-SDI 1080i or 720p at the same refresh rate (50/60
Hz). Note that it will not scale to a different resolution.
• Dual-path pixel-to-pixel processing always enabled.
• Anti-flicker filter applied when output is interlaced.
• Output format is automatically selected as follows:
DVI Input HD-SDI Output
1280x720p @ 50 Hz 1280x720p @ 50 Hz
1280x720p @ 60 Hz 1280x720p @ 59.94 Hz
1920x1080p @ 50 Hz 1920x1080i @ 50 Hz
1920x1080p @ 60 Hz 1920x1080i @ 59.94 Hz
Note: A KXI-DVI-Bridge with older firmware cannot be used at the output of the Kaleido-X.
New systems ship with a dongle that is used to set the device mode. The dongle plugs into the RS-232/GPI
port on the rear panel of the KXI-DVI-Bridge. At power-up, the device checks for the presence of this dongle.
If it is not present, the device will behave as a Kaleido input device (corresponding to Mode A described
above). If the dongle is present, the unit behaves as either a Kaleido input device, or an output device
(corresponding to Mode B described above).
KXI-DVI-Bridge Dongle
Older models of the KXI-DVI-Bridge can be upgraded. The upgrade package consists of new firmware and a
dongle. Contact Miranda Technical Support for more information.
3 The KXI-DVI-Bridge version 4.1.5 release corresponds to firmware version 8.0105.
