07 Apr 16. Osprey Video announced the launch of the Osprey 840e video capture card. Built for customers who rely on SDI ingest in high-density applications, the Osprey 840e card features four independent, highly configurable input channels.
“One of Osprey Video’s strengths is our ability to easily adapt our products to suit our customers’ needs and budgets,” said Roger Bieri, general manager, Osprey Video. “With the 840e, we created a more affordable card that lets our customers save money without sacrificing quality or density.”
Each of the 840e’s four inputs can accept video in three different formats — SD-SDI, HD-SDI, and DVB-ASI MPTS/SPTS — along with four stereo pairs of embedded SDI audio. All inputs are clock-independent, which is why each of them can ingest a different format. This versatility makes the 840e well-suited for SDI-based mobile streaming applications that involve ingesting and streaming from multiple sources, such as concerts or sporting events.
Like all Osprey 800 Series cards, the 840e comes standard with Osprey SimulStream®, a feature that allows each input to produce multiple parallel output streams with completely independent settings for color space, cropping, scaling, closed captions, and overlays. Thanks to this capability, the 840e enables simultaneous delivery to multiple applications.
In the event of signal loss, the 840e card automatically replaces lost video with color bars and presents options for text overlay and audio tones. This feature guards against failure of downstream applications due to signal loss.
In terms of video preprocessing, the 840e handles functions such as VBI/VANC closed-caption extraction/on-screen rendering; scaling, cropping, deinterlacing, and inverse telecine; and vectorscope and lumascope readings.
The 840e card supports the Microsoft® DirectShow® API and Linux drivers, while an available Osprey SDK lets developers take full advantage of the driver capabilities in the Osprey 800e Series. Users can access additional audio options through the Osprey 800a audio-expansion card.
The 840e capture card is available now.
07 Apr 16. General Dynamics SATCOM Technologies completed the construction and walk-through of the 7,000 square-foot radar receive array structure that is part of the U.S. Air Force Space Fence radar system. With the array structure complete, the General Dynamics Space Fence team will carefully dismantle the 700,000-pound steel structure and ship it to Kwajalein Atoll, Marshall Islands, for reassembly and integration into the Space Fence system. Officials from the Air Force Space Fence program office and representatives from General Dynamics SATCOM Technologies and Lockheed Martin, the prime contractor for the Space Fence program, participated in the walk-through. The structure was built at General Dynamics’ Wortham, Texas, precision manufacturing facility.
“The ground-based receive array is an elegant merger of a huge physical structure built with the precision of a complex scientific or medical instrument,” said Mike DiBiase, a vice president and general manager of General Dynamics Mission Systems. “The SATCOM Technologies-built array has the sensitivity to locate, identify and track objects as small as a softball, hundreds of miles above the Earth’s surface.”
The structure stands 12 meters tall and is about the size of two regulation NBA basketball courts placed side-by-side. It is designed to withstand earthquakes, hurricane force winds and extremes in temperature and humidity while maintaining a consistent surface flatness that varies less than one millimeter from one end of the structure to the other and from side-to-side. To prepare for the journey to Kwajalein, workers at the Wortham facility will map the structure in meticulous detail, down to the location of each individual bolt. The compo
