Other Information

The Harrier SDI Adapter is designed for format conversion of 3G-SDI and HD-SDI video streams. The input signal is supplied via the BNC connector, or as a twisted pair via the RJ45 connector. Three output formats are supported: 3G-SDI / HD-SDI output (via BNC), HDMI output, and SuperSpeed USB Type-C output providing USB Video Class (UVC) v1.1 compliant video streaming. A remote camera may be controlled using RS-485 comms via either the SuperSpeed USB port using a compatible UVC application, or via the separate USB-UART Micro-B interface. The RS-485 port and twisted-pair input share the RJ45 connector.

As well as standard 3G / HD-SDI streams, the unit automatically decodes HD-VLC encoded video streams which may typically come from a Tamron or Sony block camera fitted with one of Active Silicon’s Harrier Camera Interface Boards. Use of this end-to-end HD-VLC solution allows longer cable lengths (see Active Silicon’s White Paper on long-reach HD digital video solutions with this technology).

The unit is available as a board (as in product image), or as a cased version for use with a PC or laptop.

General information

Power Options

In both the board and cased versions, the unit may be bus powered from either USB port. The board version also has a power header for a fixed system power supply. If multiple power sources are connected, an internal power switch selects the appropriate source with the following priority:

1. System power header.
2. USB 3.0 type C port.
3. USB 2.0 Micro-B port.

Application Information

For maximum cable length applications, the input signal should be supplied to the BNC input using a good quality coaxial cable. For shorter cable length applications, the input signal may alternatively be supplied to the RJ45 input using twisted pair cable.

The unit auto-detects which input is connected, and if both are connected it gives priority to the BNC.

The input video format and frame rate are automatically detected, as is HD-VLC compression. The
selected input, speed (3G/HD) and use of HD-VLC are indicated on the status LEDs.

The RS-485 communications to the camera may be controlled via the USB Micro-B control port, or via the
USB-C port which serves as both video output and UVC control input. This selection is made via DIP switch.

The HDMI and SDI outputs are always enabled. The USB-C Video output is enabled when the port is
connected to a host SuperSpeed USB 3.x port. Connection to a host USB2.0 port will display an error.

The SDI output has a separate HD-VLC control, which means the unit can also be used to compress a standard 3G/HD-SDI input video stream.

Supported Video Formats

The Harrier SDI adapter supports a range of video input/output formats.
The SDI input and output are compliant with ST292 (HD-SDI) and ST424 (3G-SDI). The HDMI output complies with v1.4 of the HDMI specification. The USB video is UVC 1.1, USB 3.1 Gen 1 Super Speed, 5 Gbps.
