HARRIER SDI Adapter
Version 1.3 July 2019
Test Pattern
With no video input connected, a simple "bouncing ball" motion test pattern is displayed (see Figure
3 ).
To display a 1080p60 static test pattern, move DIP switch 1 to the ON position (see Figure 4).

Connecting SDI Input
When you connect a suitable HD/3G-SDI data source to the SDI IN connector (75 Ohm coax/BNC,
e.g. 1080p60), or to the RJ-45 connector (100 Ohm twisted pair, e.g. 720p60), the Harrier SDI
adapter will take a second or two to lock onto the signal and then it will provide simultaneous video
outputs to devices connected to the SDI OUT (75 Ohm coax/BNC), HDMI OUT and USB VIDEO OUT
connectors. These video outputs will have the same video format as the SDI input stream so any
monitor connected to the SDI/HDMI outputs must be able to display the video mode being received
at the SDI input.
SDI Output
Data is always provided on the SDI output in parallel with the HDMI and UVC (USB Video Class)
outputs. The video outputs will have the same video format as the SDI input stream unless the Test
Pattern is set on. (See Test Pattern section above).
HD-VLC™ Compressed SDI Video Input & Output
HD-VLC compression allows HD/3G video to be sent using lower bitrate/frequency signals; this
reduce the loss in the cable and enables the video to be sent over much longer cable lengths. The
Harrier SDI Adapter will automatically detect and decode a HD-VLC encoded input stream (i.e.
HD/3G-SDI compressed into a SD-SDI bitrate stream). Use of 1080p60 or 720p60 mode is
recommended (these compress down to 540Mbs and 270Mbps respectively).
Note: HD-VLC compression does not support all video modes, for more information please check
the datasheet. Depending on the DIP switch settings the unit can output a decoded 3G/HD-SDI
stream or a HD-VLC encoded stream on the SDI Output BNC connector.
