HELO H.264 Streaming and Recording Encoder v4.2 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, iPhone or other device and deliver the stream

directly to a Content Delivery Network (CDN) via RTMP, RTMPS, RTMPE, RTSP

(10 clients), HTTPS, RTP/UDP Unicast and Multi Unicast, or HLS (10 clients) (HTTP

Live Streaming). 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.

Configured by default for DHCP network communications, installing HELO 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. A low frame rate video monitor displays the video signal

to indicate its presence.

Using Mobile Devices

Streaming from HELO to Mobile Devices

When streaming from HELO to a mobile device, video is sent out through the LAN

port and delivered to the mobile device wirelessly using the HLS protocol. The

wireless delivery is done by a WiFi Access Point or by routing the stream through

a mobile telecom network. HELO does not have WiFi built in, and does not

support WiFi dongles in the USB port.

HELO H.264 Streaming and Recording Encoder v4.2 6 www.aja.com

Sending Video to HELO from Mobile Devices

When sending video from a mobile device to HELO for streaming, the mobile

device, such as an iPhone, iPad, or Android device, must be physically connected

to HELO's HDMI input using an appropriate adapter and an HDMI cable.

System Requirements

Remote computer configuration and control is accomplished using HELO’s

internal web server. A macOS or Windows computer with a web browser installed

is all that is required. A USB port is also required for eMini-Setup configuration.

NOTE: Safari is the preferred web browser for control on the Mac, and additionally

Chrome and Firefox on Windows. Other web browsers may work, but AJA cannot

guarantee consistent operation for all web browsers or web browser versions.

HELO REST API Documentation

AJA’s REST automation API provides a platform from which you can issue

commands to an AJA device’s internal web server, allowing remote systems

the ability to control AJA embedded or networked devices. With this control

framework, you can build integration and automation scripts, using any scripting

language, allowing you to take full advantage of the device’s functionality.

Factory Reset Button (Hardware)

A recessed Factory Reset hardware button is located between the USB ports.

Using a paper clip, press and hold for five seconds to perform a factory reset.

The hardware button does a hard reset, which resets everything, including

network connection parameters, and will also erase all saved presets, profiles, and

calendars. It is intended to be used in the factory to ensure a system is in a new

state before shipment, and for use by equipment loan or rental houses that need

to put HELOs into a new state, and also to ensure any saved passwords are erased.

NOTE: A Factory Preset button is also available on the web browser UI (Presets Screen),

but different parameters are reset from the web interface. See "Factory Reset

(Web UI)" on page 50 for more information.

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

CAUTION: Please use caution and take security into account when configuring your

HELO unit on your network. It is recommended that you place your HELO behind

a firewall so that it is not accessible on the open internet by unauthorized users.

If you have questions or concerns about how to configure HELO in a way that is

appropriate for your security needs, please consult with your IT staff or a qualified

network security consultant.

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 identify the current HELO IP

address, if configured, or to manually set the network configuration to work in

HELO H.264 Streaming and Recording Encoder v4.2 15 www.aja.com

your environment. Refer to "Chapter 4 eMini-Setup" on page 18 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.

Setting up HELO on a Static Network without eMini-Setup

If you choose not to use eMini-Setup to configure your HELO, this section

describes the steps you can take to temporarily modify your controlling

computer's IP address in order to connect to a HELO that has already had its IP

address set to its default Static IP address.

Because HELO ships with DHCP enabled by default, in order to setup a Static IP

address, you will first need to put HELO into Static IP mode via eMini-Setup or via

the Web interface.

For example, let us assume that, through using eMini-Setup, the Static IP address

of the HELO has previously been set to 192.168.101.1 with a subnet mask of

255.255.255.0.

To enable your computer to connect to HELO without using eMini-Setup, we

will walk through the network configuration steps needed for both MacOS

and Windows to temporarily configure your computer to be set to the static IP

address of 192.168.101. 2.

IMPORTANT: BEFORE following the steps below to alter your Mac or Windows network

configuration, record your existing TCP-IP settings so that you can return your

computer to normal network operation after completing this procedure.

MacOS

1. Open up the MacOS System Preferences and select Network.

2. Input the address information shown below:

• IP Address: 192.168 .101. 2

• Subnet Mask: 255.255.255.0

3. Click Apply. This will put both your computer and your HELO within suitable

address range for connection.

4. Ensure that the HELO device is connected to the Mac via Ethernet (directly

or via LAN).

5. Start Safari (or another browser) and enter 192.168 .101.1 as a web address.

6. Once connected to HELO’s web interface, recongure HELO’s network

parameters as desired.

7. Restore your computer to its normal network TCP-IP settings.

Windows

1. Use Control Panel to access your Local Area Network properties. In

Windows 10 the path is Control Panel > All Control Panel Items >

Network and Sharing Center.

2. Under Connections, click Local Area Connection for the PC’s Ethernet

port.

3. In the resulting General dialog screen, select Properties.

4. On the Networking tab, select Internet Protocol Version 4 and click the

Properties button below.

HELO H.264 Streaming and Recording Encoder v4.2 16 www.aja.com

5. Click the Use the following IP address: radio button and enter the IP

Address and Subnet Mask below:

• IP Address: 192.168.101.2

• Subnet Mask: 255.255.255.0

6. Click OK to store the changes.

7. Connect the Windows PC to HELO’s RJ-45 port (either direct or through your

LAN).

8. Point your web browser to 192.168.101.1.

9. Once connected to HELO’s web interface, recongure HELO’s network

parameters as desired.

10. Restore your computer to its normal network TCP-IP settings.

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 25 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

HELO H.264 Streaming and Recording Encoder v4.2 17 www.aja.com

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.

Refer to "Chapter 5 HELO Web Interface" on page 25 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.
