Lecture Recorder x2 User Guide
2Overview
2.1 Introduction
Epiphan’s Lecture Recorder x2™is a compact, portable solution combining both
Ethernet-based audio-video broadcast streaming and recording functionalities. It
transfers up to 30 frames per second of visual and audio information with resolution
up to 1920x1080.
Input sources can be:
a DVI/VGA/HDMI display or camera source
an analog camera (S-Video or composite) source, and
an analog audio source.
This flexibility of input sources gives the Lecture Recorder x2 the capability of
synchronizing a high quality audio stream with a corresponding video stream.
Streams can be encoded with Motion JPEG, MPEG4 or H.264 video compression.
When video from the two input sources is being used for either broadcasting or
broadcasting and recording simultaneously the following format choices are
available:
1. Independent Channel Stream, streams the video from the two input
sources using two separate URLs. Recordings consist of a single multi-track
file with two video tracks and one audio track. In this mode you cannot
publish both streams through CDN or set up two multicast RTP streams.
2. Single Channel Stream, combines the input from the two video input
sources using one URL and various picture in picture layouts. Recordings
consist of one video track and one audio track.
The Lecture Recorder x2 is connected to a network with an Ethernet connection,
once connected to the network, it can be configured and operated through an easy-
to-use web interface. Recommended maximum operating temperature: 45°C. The
Lecture Recorder x2 is ideal for educational and training institutions, creating sales
and marketing videos and technical support how to demonstrations that require
the ability to stream/record/synchronize a computer display along with live video.
Each channel which is being streamed is automatically assigned a unique URL.
Viewers are simply provided with the required URL in order for them to watch the
desired broadcast stream. Additionally, the Lecture Recorder x2 allows content
producers to also record the broadcast to .AVI, .MOV, or MPEG-TS formatted files.

Lecture Recorder x2 User Guide
When configured for dual streaming, the Lecture Recorder x2 is being used for the
simultaneous broadcasting from both a DVI/VGA/HDMI input source and either a
composite or S-Video analog input source if this is not the case of publishing stream
or multicast RTP stream. In addition to a single URL showing both streams, viewers
may obtain two different URLs one for each of the input sources making up the
broadcast. However, when the Lecture Recorder x2 is also recording a broadcast
consisting of video input from its two video sources, it always records both video
input sources into a single multi-track .AVI, .MOV, or MPEG-TS file. Whether this
multi-track file consists of one or two video tracks depends upon whether the
recording is being done using the Single Channel Stream configuration or the
Independent Channel Stream configuration.
When recording broadcasts, recorded video files are stored in internal solid-state
memory. Recorded video files can be archived to a network storage device such as a
FTP server or copied to an inserted USB drive. When using FTP to transfer recorded
files, the internal memory is used to provide buffering such that in the event the
network is experiencing slow transfer rates, no captured data will be lost.

blinking.
Green and blue LEDs: When the Lecture Recorder x2
device first starts up, the blue LED lights up. A few
seconds later the green LED lights up. After about
another 20 seconds the blue LED turns off, leaving the
green LED on indicating that the Lecture Recorder x2
has started up and can start capturing images. During
operation the blue LED blinks during video signal test
operation and when the system tunes video
parameters (e.g. VGA parameters).
Blue LED: The blue LED blinks to indicate that the
Lecture Recorder x2 is recording received images. If the
files are not being recorded, the blue LED remains off.
Note: Sometimes it may take more than 20 minutes to
power up the device. During this time the blue LED is
on and the green LED is blinking. It means that the
Check disk function started automatically when the
device powered up.

It is important to note that due to resource constraints,
simultaneous usage of multiple USB devices can
seriously affect the performance of the Lecture
Recorder x2.

3.2.8 Power over Ethernet (PoE) Injector
The Lecture Recorder x2 incorporates a Power over Ethernet (PoE) technology. PoE
delivers both data and electrical power to an Ethernet enabled device using a single
Ethernet cable. This eliminates the need for the Lecture Recorder x2 to be situated
close to a power outlet. This allows more freedom in its placement.
PoE injectors supply or inject direct current (DC) power through network cables to
power network devices.
4Getting Started
4.1 Supplying Power to the Lecture Recorder x2
To provide power to the Lecture Recorder x2, plug the provided PoE adapter into a
10/100Base-T Ethernet network using an Ethernet cable. This network must be
running the TCP/IP protocol.
If your network does not provide Power over Ethernet, connect the Lecture
Recorder x2 to an AC power outlet with the PoE adapter/injector connected to an
Ethernet cable and plugged into the Lecture Recorder x2’s RJ45 Ethernet port.

Getting Started
16
Lecture Recorder x2 User Guide
Regardless of the power source once connected, the Lecture Recorder x2 now
powers up. Its power and activity LEDs will now light up following their start up
sequence.
4.2 Confirm Input Signals are Received
Confirming that the input signals are being received by the Lecture Recorder x2 can
be done once the Lecture Recorder x2 has been powered on and the input sources
have been started.
First, check that the Lecture Recorder x2’s red LED is blinking. A blinking LED
indicates that the Lecture Recorder x2 is capturing images. If the red LED does not
start flashing, check the input sources to ensure that they are transmitting a signal.
Additionally, check that all cables from the input sources to the Lecture Recorder x2
are connected correctly.
Depending on the input source, the Lecture Recorder x2’s output signal ports can be
used to confirm that data from specific input sources are being captured
4.2.1 Checking the Signal from a DVI/VGA or HDMI Input source
The Lecture Recorder x2 has a DVI output port that is used to confirm that the signal
from any of the above sources is being captured. In order to perform this
verification ensure that there is an input source streaming to the Lecture Recorder
x2 using its DVI input port. If yes, then connect a monitor to the Lecture Recorder x2
using the DVI output port and the appropriate DVI cable. The monitor will then
display any data being captured by the Lecture Recorder x2 via its DVI input port.
4.2.2 Checking the Signal from an S-Video or Composite Source
The Lecture Recorder x2 does not come equipped with a mechanism to confirm the
quality of the video input being received via its S-Video input video source.
However, you can trouble shoot by this source by connecting an S-Video or
composite receiver such as a TV or monitor to confirm that a high quality signal is
being generated by the video source prior to connecting the S-Video or composite
source to the Lecture Recorder x2.
