Take a look into the HELO Plus and its exciting features in this informative video.

PlayToStream allows the user to stream – via either or both of the Stream outputs – a previous program that was recorded on a HELO Plus and .mp4 and .mov clips recorded on a HELO classic system, stored either on local SD or USB storage or on external SMB or NAS systems. The system can stream live video out of one Stream output while simultaneously performing a PlayToStream action on the other Stream output. The system can also record that live stream while simultaneously performing the PlayToStream output – so a single HELO Plus can simultaneously play back a previously recorded session, stream a live session and record that live session without the need for additional equipment.

HELO Plus can expand the number of audio channels available for streaming and recording from 2x channels (a single stereo pair, the standard configuration) to 4x channels (two stereo pairs). This enables multiple dual language workflows, as different languages can now be carried on each stereo pair – as for example, enabling “home” and “away” commentaries in both English and French for Ice Hockey games.

Additionally, this option gives the user the ability to extract a stereo audio service from any of the 4x stereo pairs that may be embedded into an SDI signal (Audio 1&2, Audio 3&4, Audio 5&6, Audio 7&8) and use them in either of HELO Plus’ Audio sources for both streaming and recording.

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.

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.

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.

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.

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 stop 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. 

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.

In this use case, a sports channel 1080p59.94 video feed is being commentated on in the studio, with the video output and embedded audio being passed directly to the SDI input of the HELO Plus. The HELO Plus streaming content is monitored using an HDMI monitor and headphones.

With the optional 4-Channel audio support, the first encoder is set to encode the video and audio as an RTMP stream in English, while the second encoder is set to output an RTMP alternate language stream. HELO Plus allows high quality sports feeds with higher frame rates of 59.94 and 60 to be encoded easily, with greater detail and motion than lower frame rate content, offering an enhanced user experience.

In this use case, the live event PGM feed is passed to the SDI input of the HELO Plus. The HELO Plus streaming content is monitored using an HDMI monitor and headphones. The first encoder is set to output an RTMP with an English language stream, while the second encoder is streaming an alternate language while simultaneously recording directly to an SD card as a backup for later editorial use or restreaming with the optional PlayToStream feature.

In this use case, a college lecture is taking place. The HELO Plus receives video over SDI of the lecturer. At the same time, the presentation on the lecturer’s laptop is being output via HDMI to the HDMI of the HELO Plus.

The HELO Plus streaming content is monitored using an HDMI monitor and headphones. The HELO Plus has been set up to create a layout for picture-in-picture. In this case, the lecturer's video is scaled down and moved to the lower right corner as an overlay of the presentation.

This picture-in-picture combined output is passed to both encoders, with the first encoder offering a stream for students outside the facility via RTMP. At the same time, the second encoder utilizes HLS for delivery to a college breakout area.

In this use case, the switched video output of a studio production is being recorded as a ProRes master on an AJA Ki Pro Ultra 12G. The Ki Pro Ultra 12G passes the video and audio via SDI to a HELO Plus. The HELO Plus is configured for a layout that shows the production video scaled down with a composite background provided by the frame store.

The Ki Pro Ultra 12G and HELO Plus are connected to the same Ethernet network, configured to be a group, with Ki Pro Ultra 12G as the leader. Hitting record on the Ki Pro Ultra 12G triggers the HELO Plus to start streaming and recording to USB simultaneously.

Grouping HELO Plus with other AJA video devices offers even more sophisticated control, with simultaneous synchronization for recording and streaming across multiple devices.
