Osprey flying for ATG

6 March 2007

ATG Broadcast has won multiple orders from two major European broadcast industry players — Cologne-based G&L Geissendoerfer & Leschinsky GmbH and IdeasUnlimited.TV – for its Osprey series of video capture cards. G&L Geissendoerfer & Leschinsky GmbH is one of Germany’s most innovative streaming service providers, and has ordered 20 Osprey 230 video capture cards and 14 Osprey Simulstream multi-streaming cards.

The Osprey-230 is a half-slot low-profile PCI bus card for capturing full-motion video from a standard composite analogue source. It includes logo/bitmap overlay/watermarking, hardware audio gain control, 32, 44, 48 kHz audio sampling rates, and authoring software. Multiple cards can be used in a single system.

Osprey SimulStream video capture cards allow simultaneous multiple streams to be created at different bitrate speeds from a single source. A single card can create as many different streams from a single source (analogue or digital) as the processing power of the host PC/encoding station can handle. Typical examples are six simultaneous realtime streams comprising three streams of 56, 128 and 384 kb/s in Windows Media format and three streams of 56, 128 and 512 kb/s in Real format.

Fifteen Osprey 440 multi-channel processors and five 230 cards were purchased by IdeasUnlimited.TV. Started and managed by Glyn Powell-Evans (founder of automation specialist OmniBus), IdeasUnlimited.TV specialises in broadcast transmission verification and monitoring of television content.

The Osprey 440 is designed for applications where multiple channels of video need to be captured and processed independently. It allows four analogue video and audio sources to be capture and streamed simultaneously. Four standard alarm inputs and four alarm outputs are incorporated, supported via an Osprey AVStream driver. Twelve additional internal auxiliary audio and video inputs can be switched in as alternatives to the rear panel connectors (three per channel).

“Early applications of streaming video tended to be over local area networks where clients could be sure of high transmission bitrates,” commented ATG Broadcast MD, Graham Buchanan. “Internet delivery infrastructure has gradually improved in speed and reliability throughout the world to the point where content providers are able to transmit direct to their audience. Given the continuing worldwide development of IP infrastructure and ever-improving cost-efficiency, this technology has a tremendous future.”
