The PANORAMAdtv HD2SD down-converter
is a compact, convenient, and cost effective
solution for converting HD-SDI to SD-SDI
and analog video in the modern SD and HD
broadcast studio environment.
The HD2SD accepts HD-SDI (SMPTE
292M/274M/296M) signals for conversion to
SD-SDI (SMPTE 625i50 or 525i59.94) video.
The down-converted SD-SDI signal is also
converted to the selected analog output
type (Component, RGB, or Composite/S-
Video). HD to SD down-conversion is 10-bit
with over-sampling of 16x for SD-SDI signals.
HD-SDI input format is detected automati-
cally and the various video output options
are selectable by setting two external 10-
position DIP switches.
Eight channels of audio is passed as 20-bit
or 24-bit and the unit can also generate
its own embedded AES audio test tones.
A range of additional features is available,
including 4:3, 16:9, or 14:9 safe action grati-
cule, SD pedestal, vertical blanking, anamor-
phic or letterbox output, and generation of
a wide range of useful video test patterns.
Two LEDs on the units rear panel indicate
power and HD-SDI signal lock status. Size of
the unit is relatively small with dimensions
of 4” x 3.4”x 1”. Power may be provided by
an optional external 12V power supply with
locking connector.

HD/SD-SDI Input
This connector accepts high-definition HD-SDI signals to be down-converted to SD-SDI signals.
SD-SDI Outputs (1 and 2)
Each of these two unbalanced BNC connectors output SD-SDI video signals down-converted from the HD-SDI signal
entering the unit at the input (Item 1). Each connector outputs the same signal. Note that when the unit is set to output
audio test tones, the audio signals are embedded and output from these connectors.

APower Supply Connector
A 12V DC power supply is connected here to provide power to the unit.
Power Indication LED
This LED lights up GREEN to indicate that the unit is receiving power.
Signal Lock Status LED
This LED lights up GREEN to indicate that the HD-SDI input signal is "locked". The LED lights up AMBER to indicate
an unlocked signal. The LED remains unlit if no source is attached to the input.
Option DIP Switches (1 and 2)
These two 10-position DIP switches modules (1and 2) are used to set the available options for the HD2SD. For detailed
information about the available options and how to set them, see details starting on page 10.

Y/G/COMP Output
• Component = outputs Y(Luminance) signal
• RGB = outputs GREEN (G) signal
• Composite = outputs Composite signal (not available from HD-SDI source*)
PB/B/C Output
• Component = outputs PB(BLUE color difference) signal
• RGB = outputs BLUE (B) signal
• S-Video = outputs C(Color) signal (not available from HD-SDI source*)
PR/R/Y Output
• Component = outputs PR(RED color difference) signal
• RGB = outputs RED (R) signal
• S-Video = outputs Y(Luminance) signal (not available from HD-SDI source*)
HD2SD Settings - DIP Module 1 and 2
The various options are selected by setting the switches on DIP Module 1 and DIP Module 2.
DIP Module 1 is used to set the analog output type (converted from the down-converted SD signal), SD pedes-
tal, graticule type, center cross, embedded audio resolution, video anti-alias filter, and down-converter output
format.
DIP Module 2 operates in two selection modes; Video/Audio Options mode and Video Test Pattern mode.
When switch 9of DIPModule 2 is in the UP position, it is in Video/Audio Options mode and is used to set the
down-converted aspect format, SD raster output and graticule aspect ratio, EDH, and audio test tones. When
switch 9of DIPModule 2 is in the DOWN position, it is in VideoTest Pattern Mode is used to select video test
patterns for output.
DIP Module 2 also features two refresh modes as set by switch 10; Update Mode and Update Pause Mode. In
Update Mode the DIPswitch is continuously monitored for changes to its settings and so the unit will update it’s
function at the first detected switch change. When making multiple switch settings, the user should place the unit
into Update Pause Mode by setting DIP Switch 10 into the DOWN position. This pauses the updating of the
DIP switch settings. When the desired multi-switch setting has been made, the unit should be placed back into
Update Mode by placing DIP Switch 10 into the UP position so that the new setting configuration can be read
and enabled by the unit.
See the procedures for the selection modes in the following pages for more information on how to use the refresh
modes.
HD2SD Front Panel Features
3Analog Output Connectors (PR/R/Y, PB/B/C, and Y/G/COMP)
The converted analog video signals are output from these three connectors. The analog output type is selected by setting
Option DIP Switch 1 (Item D). Selecting component outputs PR/PB/Y signals from the three connectors, selecting
RGB outputs Red/Green/Blue signals, and selecting Composite/S-Video outputs Y/C signals (S-Video) from two
connectors (Items 3a and 3b) and a Composite signal from the third connector (Item 3c). See 3a, 3b, and 3c below.
