HD2SD
HD-SDI to SD-SDI Down-Converter
and Video/Audio Test Signal Generator
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 259M) 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 automatically
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. A range of additional features is available, including 4:3, 16:9, or 14:9 safe
action graticule, SD pedestal, vertical blanking, and anamorphic or letterbox output. Two LEDs on the units rear panel indicate
power and HD-SDI signal lock status. The unit also functions as a video and audio test signal generator providing a wide range
of useful video test patterns and embedded audio test tones.
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.
