Chapter 1 – Introduction
Overview
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 CIFS network storage. HELO Plus
also provides Picture-In-Picture and graphics functionality in hardware for
compelling presentations made simple.
Hardware
HELO Plus has 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 fan-less 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.
Dual Streaming Outputs Plus Record
HELO Plus has dual encoders and dual stream outputs, giving the flexibility to
create different output settings from a single input source. The two streams can
have different packaging settings and different output frame size which means
that a single content stream can be presented in two ways to serve a wider
audience. It can 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.
Layouts for Picture-in-Picture
HELO Plus brings the 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. Additionally, each live
video source can be used in its picture-in-picture (PiP) element.
