2. Introduction
The IQQMD00 provides conversion for Quad-link Ultra HD SDI inputs to SDI outputs in
1080p, 1080i, 720p or SD formats. This allows Ultra High Definition signals to be integrated
into existing HD/SD-SDI workflows and monitored on standard 1920 x 1080 displays
removing the need for expensive Ultra HD specific equipment and monitors.
Drawing on Snell's extensive experience in conversion technology the IQQMD00 uses high
quality scaling and filtering technology to down convert and align the quad-link input to
provide a clean and sharp HD/SD output, ideal for monitoring and other signal distribution
applications.
The video output from this module is SDI with an option to add fiber, copper or HDMI SFP
module to extend the output capabilities of the IQQMD00.

6.2 Video
The Video pane enables you to specify and view the settings and status for all the video
inputs, video output, monitor output and reference.
6.2.1 Inputs
The following information is provided:
Fig 17. Video
Name Description
Valid Input Standards The Valid Input Formats check boxes specify the video input
standards that the module will accept. The module will
automatically detect the standard of the received input and
indicate any signal that does not comply with the selected video
formats as INVALID.
Input Mode Selects either Sony or SMPTE pixel interleave standard for the
4K-UHD input signal.
In Sony mode, the inputs are discreet 4k images and are
displayed one per quadrant. Normally, each input would be ¼ of
the image and would combine to be a single picture. If you
emulate it by providing 4 ordinary 4k pictures, they appear 1 per
quadrant.
In SMPTE mode, each input is pixel multiplexed so if you present
the same ordinary 4k signal into each input, it always appears as
a single picture.

6.3 System GPIO
The GPIO controls are used to configure the six General Purpose Input / Output (GPIO)
connector functionality.
6.3.1 GPIO 1, 2, 3, 4, 5 & 6
The following options enable you to control and monitor the GPIOs.
Fig 21. System GPIO
Name Description
GPIO The options are:
•Unused - When the GPIO is inactive
•Input - Configures the GPI as an input. This enables you to choose
what action occurs when the GPI input receives a driven state High
(>2Volts) or Low (<0.8Volts)
•Output - Configures the GPI as an output. This enables you to choose
what trigger occurs to produce an output signal at the GPI connector
when the GPI output is driven Low (+0.5V typical) or, if the Invert func-
tion is selected, Driving the GPI output High (+5V typical)
Status Displays the GPIO status.
Invert Configure the GPI to be active low when it is an Output.
