AJA HELO PLUS High Quality Streaming and Encoding
AJA HELO-PLUS is a compact, advanced H.264
streaming and recording stand-alone appliance. HELO Plus offers both SDI and
HDMI I/O with the capability to stream up to 1080p60 to a Content Delivery
Network and record simultaneously. Two separate streaming destinations can
be set up, and recordings can be made to a combination of SD card, USB
storage, and NFS or SMB network storage. HELO Plus also provides
Picture-In-Picture and graphics functionality in hardware for compelling
presentations made simple.
AJA HELO-PLUS v.2.0 firmware adds many new
features, including new optional upgrades with a free trial period –
PlayToStream, and 4-Channel Audio. PlayToStream offers users the ability to
re-stream a previously recorded program at a later date to either or both of
the Stream outputs. The system can simultaneously perform PlayToStream and
live encoding, sending each to its own Stream outputs. 4-Channel Audio
support means you can stream two separate audio pairs via each encode for
multi-language support.
AJA HELO-PLUS offers high-quality streaming
with ultra-reliable performance for any critical streaming service needs,
including eSports, news, sports, education, creator, live events, and
beyond.
Hardware
AJA HELO-PLUS is compact, with a very small desktop
footprint. It offers stand-alone capabilities with stream and record buttons
on the front of the unit as well as LED indicators. Audio level meters
provide valuable feedback about incoming audio.
AJA HELO-PLUS is
fanless and silent, allowing it to be used almost anywhere without fear of
introducing noise. SD card and USB ports are also situated on the front of
the unit for easy access.
Remote or Local Control
HELO Plus can be easily configured remotely on a
standard web browser, via the Ethernet connection, and using a desktop
computer, laptop, or iPad. Every function of HELO Plus is accessible in the
Web UI, with multiple HELO Plus devices being easily controllable via a
tabbed browser window. Once set up to your requirements, HELO Plus can also
be controlled via the stream and record buttons on the front of the device,
with audio-level LED meters providing feedback for monitoring, or the system
can be controlled directly from the included web-based UI. There’s also the
option for remote control via the system’s integrated REST API.
SRT Support
SRT is an open-source video transport protocol and
technology stack, developed and pioneered by Haivision, that optimizes
streaming performance across unpredictable networks with secure streams and
easy firewall traversal, bringing the best quality live video over the worst
networks.
The SRT Open Source Project, supported by the SRT Alliance,
is a collaborative community of industry leaders and developers striving to
achieve lower latency internet video transport by continuously improving
open-source SRT.
HELO Plus includes SRT (plus encryption) to ensure
you are well-positioned to deliver streaming video content securely, with
low latency and secure reliability.
HELO Plus offers all the
professional digital I/O you need to make it the heart of your streaming
service. The easy-to-access front panel buttons make starting and stopping
your stream simple.
Operational Flexibility
HELO Plus’ small footprint form factor and silent
operation allow it to fit on any desktop, with the operator using the
easy-to-access front panel start/stop buttons. But just as simply, HELO Plus
can be operated remotely from a desktop or laptop computer via Ethernet,
which is especially useful for multiple HELO Plus use cases.
HELO
Plus is designed to give you the flexibility to configure and deploy HELO
Plus to your needs in the field, home, or studio. HELO Plus fits any
streaming need imaginable, from sports, news, creator, education, eSports,
remote workflows, and many more.
REST API capabilities provide
control for all functions of the HELO Plus, regardless of the scenario,
allowing for user-developed integration and automation.
Simultaneous Stream and Record
HELO Plus has the capability to stream and record
up to 1080p60 simultaneously in the following combinations:
• Stream
to two destinations and record to SD local storage simultaneously •
Stream to two destinations and record to USB local storage simultaneously
• Stream to two destinations and record to NFS/CIFS network storage
simultaneously
Having a recorded backup of the video stream provides
a high-quality H.264 version for editing applications, with the most
suitable storage being selected. Network storage may make more sense for
edit sharing, while an SD card or USB recording provides an easy takeaway
for clients or editors.
Calendar Integration
HELO Plus opens up a world of new streaming
workflows for AV, live events, houses of worship, webcasting, corporate
communications, production, and post. HELO Plus offers a scheduler that
triggers pre-planned start and stops recording and streaming media,
simplifying projects requiring definitive schedules.
The schedule may
be programmed locally through HELO Plus’ web UI, importing .ics files, or
linking to external calendar providers such as Google Calendar.
Layouts – Powerful Multi-Input Video
Processing
HELO Plus brings an exciting layouts feature,
allowing multiple inputs to be combined into a single screen with a graphic
element overlay. A layout enables the user to combine the SDI input and the
HDMI input into a single output stream and then add a graphic (video + key)
into that composite. The layout can have up to three layers, and their
priority can be arbitrarily adjusted to suit the customer’s needs.
In
addition to the layering engine, both the SDI and the HDMI layers can be
arbitrarily downscaled and positioned anywhere in the frame. Effectively,
each live video source can be used in its picture-in-picture (PiP) element.
The system also has an internal matte generator, which can be used as
the background. In this way, the graphic can be keyed over the dual PiP
images, which are “over” a flat matte background.
The system can
accurately switch from one layout to another frame, allowing the user to
“cut” between layouts during a streaming session. Layouts are stored in one
of the 20 Presets, allowing users to recall all the parameters needed for a
specific purpose. There are ten layouts stored in each preset so that the
user can recall the show’s preset and switch between those ten layouts at
will.
The graphics system is equally impressive – It stores 20 images
in its internal, non-volatile memory.
Dual Streaming Outputs
HELO Plus has dual encoders for streaming outputs,
giving the flexibility to create different output settings from a single
input source. The two encoders can have different packaging settings and
different output frame sizes, which means that a single content stream can
be presented in two ways to serve a wider audience.
It can also be
duplicated across both encoders for added resilience. Either of these
encoder outputs can serve as the source for the HELO Plus recording system
as well.
Simple but Flexible
The simplified signal flow for video within HELO
Plus neatly highlights the flexibility of the device. Tracing a simple
pathway for each video input illustrates the encoder, graphics, recording,
and new PlayToStream options.
