NCast Presentation Recorder Reference Manual
1. Introduction
1.1. PURPOSE
The NCast Presentation Recorder Reference Manual is intended for the Audio/Video or Network engineer
who will be tasked with the job of installing and setting up a Presentation Recorder or a system of multiple
Presentation Recorders. This guide is designed to cover topics in depth and to assist in optimizing the
performance of a Presentation Recorder.
1.2. DOCUMENT OVERVIEW
This document is divided into two major sections: the theory of operation and a discussion of parameter
settings.
1.3. PRESENTATION RECORDERS – BASIC MODELS
The Presentation Recorder is a stand-alone network communications appliance which captures RGB (VGA),
omposite, omponent, 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 (192 x12 ) input resolutions with up to 1 8 p (192 x1 8 ) 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 (192 x12 ) input resolutions with up to 1 8 p (192 x1 8 ) 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:
N ast orporation Revision 2.2
Page 6

NCast Presentation Recorder Reference Manual
•Two independent HD encoders – With identical inputs, one encoder may be setup to stream and record a
high-bandwidth, high-resolution stream and the second encoder provides for a reduced resolution,
reduced bandwidth stream.
•Dual wide-screen delivery – One encoder transmits a hi-def camera stream, and the second transmits a
wide-screen presentation. Telepresence at a budget price!
•Synchronized Encoders – Two HD wide-screens side by side, giving a dual-HD panorama, or a 3D left-right
image.
•Two-way Interactive – One encoder is configured for streaming send, and the second is setup for
streaming receive.
•Fail-Safe System – Each encoder independently transmitting the same material. Should one fail, the
receivers can switch to the other.
•Hot Standby – A spare unit for critical applications.
PR-HD-Basic-P - A flange-mounted unit with streaming and archiving capabilities. This is a very
small form-factor chassis suitable for mounting on the walls of a podium, on top of or underneath a
podium shelf, in a mobile cart, or on a wall in an equipment room.
PR-HD-Basic-M - A desktop unit with streaming and archiving capabilities. This is a very small
form-factor case suitable for desktop or mobile cart applications.
All PR-HD Series units share a core operating system and base set of features. The mainboard and
connector set is similar for all units. Please review the product spec sheets for further details.
1.4. PRESENTATION RECORDERS – EXTREME MODELS
The Presentation Recorder Extreme has all the features of the Basic model but in addition will record in 1080
definition, stream in 1080 (but simultaneous recording and streaming at this resolution is not allowed). There
is also an HDMI output connector for an all-digital connection to a display monitor.
1.5. PRESENTATION RECORDERS – ULTRA MODELS
The Presentation Recorder Ultra has all the features of the Extreme (except HDMI Out) and in addition
supports 3G-SDI digital input.

1.6. PRESENTATION RECORDERS – CONNECTOR OPTIONS
The following diagram describes the back-panel connectors available:
Backpanel for PR-HD-Basic-M, PR-HD-Basic-P
•Serial Control – Wired control from a touch panel, such as restron or AMX
•Ethernet – onnection to the Internet
•XLR Audio – Balanced XLR input connector and additionally a balanced 0.25” connector
•VGA – Input from the presenter's P
•VGA Loopback – VGA output, usually to the room projector
•VGA/Component Out – RGBHV or Y-Pb-Pr output to the local display
•USB – For specifying a static IP connection with a USB drive or saving an archive file
•Line-In, Line-Out, Mic-In - Unbalanced 3.5 mm. audio connections. Stereo for Line-In, Line-Out
•HDMI – Video input from cameras or computers, audio not supported
•DVI-D – Digital input
•DVI-A – Analog RGBHV input or Y-Pb-Pr component from a camera source
•Displayport – Input from the Displayport output of a computer
•SDI – 3G-SDI Serial Digital Input
•Composite – NTS or PAL input
Note: onversion of HDMI or DVI signals to Displayport requires an active (not passive) adapter.

1.7. PRESENTATION RECORDERS – GENERATION 1 VS. GENERATION 2
Earlier versions of the PR-720 and PR-HD Presentation Recorders had a different backpanel and connector
lineup. Documentation on these first generation units is found in hapter 14.
1.8. PRESENTATION RECORDERS – PHOENIX CONNECTOR WIRING
The Presentation Recorder rack mount models come with a Phoenix balanced audio connector.
