HELO H.264 Streaming and Recording Encoder v1.1r1 5 www.aja.com
Chapter 1 – Introduction
Overview
HELO is AJA’s first hardware-based H.264 solution. HELO can receive video
output from a switcher, camera or other device and deliver the stream directly
to a Content Delivery Network (CDN) via RTMP or RTP/UDP-TS. HELO can also
simultaneously record the video to its built-in SD slot, to a USB flash drive
attached to its USB 2.0 port, or to a local shared network drive via its Ethernet
port. This lets you configure your recording and streaming independently for
maximum efficiency and flexibility.
HELO has both HDMI and SDI video interfaces for inputting either type of signal,
as well as analog stereo audio in and out. Two hardware buttons are conveniently
located on the front, one for stream and one for record.
HELO is configured by default for DHCP network communications, so installation
can be as easy as just plugging in the Ethernet cable. A USB connection with AJA’s
eMini-Setup application also allows quick access directly to the HELO hardware
for network configuration, if necessary.
HELO uses a web browser based UI, where all of HELO’s controls are ready
to use. The robust web browser UI allows you to setup and configure your
CDN connection before you even arrive at your event. Once there, even an
inexperienced operator can start and stop streaming and recording with simple
button pushes. The web UI also provides complete control of HELO’s operations
from a remote location.

Chapter 3 – HELO Installation
Overview
An initial HELO installation includes the following steps:
1. Apply power to HELO.
2. Connect HELO to your Ethernet network.
3. Determine HELO’s IP address (DHCP), or congure HELO’s network settings,
using eMini-Setup and a USB connection.
4. Disconnect eMini-Setup and continue device conguration from the Web
Interface.
5. Launch a web browser and access HELO using its IP address.
6. Connect the HELO inputs and outputs.
7. Congure HELO’s basic operation.
8. Congure a HELO Recording Prole and a Streaming Prole.
9. When HELO is properly installed and congured, recording and/or
streaming can be started and stopped simply by pressing the buttons on
the front panel, or by using the web interface.
The current HELO configuration settings are retained, even when powered off, so
subsequent installations for an identical recording and/or streaming session can
be done with the following simple steps:
1. Apply power to HELO.
2. Connect HELO to your network and connect the HELO inputs and outputs.
3. Press the Record or Stream button to start and stop recording and/or
streaming.
Initial HELO Installation
Network Configuration
HELO requires a network connection to stream to the internet or record to a
network drive. HELO is shipped from the factory with DHCP enabled, so if your
network has a DHCP server, by simply connecting HELO to your network with
an Ethernet cable the DHCP server will assign HELO a compatible IP address.
However, you will need to know that IP address before you will be able to access
HELO’s internal web server for initial configuration.
The eMini-Setup application, included with the HELO software and available
as a free download from the AJA website, lets you identity the current HELO IP
address, if configured, or to manually set the network configuration to work in
your environment. Refer to "Chapter 4 eMini-Setup" on page 16” for information
about installing and using AJA’s eMini-Setup application.
Once configured and connected to your network, HELO can be used for recording
to locally inserted media (USB stick or SD card). For streaming or recording to a
network drive additional HELO configuration is required. A properly configured
HELO can stream and record simultaneously or perform each task individually.

HELO H.264 Streaming and Recording Encoder v1.1r1 14 www.aja.com
HELO Recording Quick Start
HELO is shipped from the factory configured with the following basic recording
settings:
• Input - (HDMI, Video Source on HELO web browser Cong screen)
• Audio Input Source - (HDMI, Audio Source on Cong screen)
• Recording Target - (SD, Recording Media Type on Recording Proles screen)
• Recording default format is Selected Input Video Geometry Full Frame Rate
20Mb MOV
The easiest way to record is to simply apply power to HELO, connect HELO’s HDMI
port to a valid video/audio source, insert formatted SD media into HELO’s SD slot,
and then press the Record button on HELO’s front panel. The Record button and
SD LEDs will blink green while recording. Pressing the Record button again stops
the recording.
To change HELO’s configuration settings (other than IP address) requires a
network connection to HELO and a computer running a web browser, as
described above. You can then change the input source (SDI or HDMI), recording
target (USB, SD card or network drive), and the recording format. Refer to "Chapter
5 HELO Web Interface" on page 23 for detailed information.
NOTE: On Mac systems, after deleting files from a USB thumb drive or SD card, you must
also empty the trash to make that space available on the media.
HELO Streaming Quick Start
HELO is shipped from the factory configured with the following basic streaming
settings:
• Input - (HDMI, Video Source on HELO web browser Cong screen)
• Audio Input Source - (HDMI, Audio Source on Cong screen)
• RTMP Stream Type - (RTMP on Streaming Proles Screen)
• Streaming default format is Selected Input Video Geometry Full Frame Rate
20Mb RTMP
Streaming requires a valid video/audio source, a network connection, and HELO
configured with specific settings to match the Content Delivery Network (CDN)
you will be using. Typically these CDN credentials for RTMP streaming include the
following:
• RTMP Server URL
• RTMP Stream Name
• RTMP Username
• RTMP Password
The Server URL and Stream Name combine to create the information needed for
the RTMP server to understand the incoming stream.
You obtain this information directly from the CDN and, using a web browser,
enter the data into HELO’s Streaming Profiles configuration screen. This
information is intended only for your streaming session(s).
Caution! Do not share your streaming credentials with anyone. That information
allows anyone to access and stream to your channel without your knowledge
or permission. CDNs will not ask for a stream key by email, so ignore any such
requests. HELO stored presets contain streaming credentials. If you share an
exported preset to someone, that person can extract the credentials. Before
loaning the device to someone, or returning it as a rental, the factory reset
button should be used to clear the device of sensitive information.
Your CDN or Video Server may also have other recommended settings for your
streaming session. For best results you should follow those recommendations
closely.

HELO H.264 Streaming and Recording Encoder v1.1r1 15 www.aja.com
Refer to "Chapter 5 HELO Web Interface" on page 23 for detailed information
about HELO streaming configuration.
After you have entered the CDN credentials into HELO and configured any
other streaming settings, you can simply connect a valid video/audio source to
HELO (either HDMI or SDI) and press the Stream button on HELO’s front panel.
Depending on the CDN/Video Server being used there may be a delay before the
streamed signal is viewable on the output.

Chapter 4 – eMini-Setup
Overview
This chapter describes using the eMini-Setup application to initially communicate
with and configure the HELO over a direct USB connection. Once configured,
the HELO can be accessed via an Ethernet network using a web browser.
Subsequently, that device can then be reconfigured over that network, using its
IP address and built in web server.
NOTE: The eMini-Setup application is only used to setup selected Ethernet capable AJA
devices, and cannot be used to connect to or setup other AJA Mini-Converters.
The general procedure is:
1. Acquire eMini-Setup from the AJA website and install the eMini-Setup
application onto a computer.
2. Connect the HELO to that computer’s USB port.
3. Launch the eMini-Setup application.
4. Go to the Control Network tab and Media Network tab, where the IP
address settings are displayed. You can use the existing DHCP assigned IP
address, or it can be changed manually.
5. You can also use eMini-Setup to load rmware to the device, although this
can also be done quickly and easily using the web browser interface.
