1.1. P URPOSE
The NCast Presentation Recorder Reference Manual is intended for the Audio/Video or Network engineer

Presentation Recorders. This guide is designed to cover topics in depth and to assist in optimizing the
performance of a Presentation Recorder.

This document is divided into two major sections: the theory of operation and a discussion of parameter
settings.
1.3. P RESENTATION R ECORDERS – B ASIC M ODELS
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 following Presentation Recorder models are covered by this documentation:
PR-HD-Basic-R – A rack-mounted unit with streaming and archiving capabilities. The PR-HD-Basic-R
introduces support for up to WUXGA (1920x1200) input resolutions with up to 1080p (1920x1080) capture
resolutions and PiP (Picture In Picture) video and graphics overlay.
PR-HD-Basic-D – A rack-mounted unit with streaming and archiving capabilities. The PR-HD-Basic-D
introduces support for up to WUXGA (1920x1200) input resolutions with up to 1080p (1920x1080) capture
resolutions and PiP (Picture In Picture) video and graphics overlay. This unit has two independent and
identical encoders in a single 1U rack-mount chassis (each encoder and its power supply occupy ½ rack).
The dual-encoding capabilities of this model enables many different applications, for example:
