The Presentation Recorder is a stand-alone network communications appliance which captures RGB
(VGA), Composite, Component, DVI, HDMI, Displayport and optionally 3G-SDI signals from a desktop or
laptop, compresses the image with an industry standard compression algorithm, records the capture to a
file, packetizes and transmits the imagery as an internet media stream, receives a media stream from the
internet, decompresses the imagery, and presents the received information to a viewing audience
through use of a large-screen monitor or via a room projector. Presentation Recorders are able to
archive the media stream in real-time while simultaneously webcasting, allowing for playback by the
recipient at a later date.
The PR-Hydra-R brings unique capabilities to the Presentation Recorder lineup in being able to
simultaneously record and stream two hi-def images for capture or live viewing.
