The OT T service provider chose Harmonic’s EyeQ™
content-aware encoding solution based on its exclusive
abilities to boost QoE, reduce bandwidth, and decrease CDN
costs for OT T services. The EyeQ solution is an enhancement
to Harmonic’s widely deployed software-based PURE
Compression Engine™ and sits at the heart of the company’s
acclaimed software-based Electra™ X media processing
platform, which had previously been deployed by the
With the EyeQ solution, the service provider is perfectly
equipped to deliver high-quality HD live content to over
150,000 subscribers on a wide range of connected devices,
including set-top boxes, Apple TVs, and Android™ applications
on streaming media devices and LG TVs.
One of the unique selling points of EyeQ content-aware
encoding is that it eliminates client buffering. It does this
by creating a reduced and variable video bitrate stream
for each ABR profile with zero buffering to ensure the
best viewing experience for end users on any screen.
What’s especially innovative is that Harmonic’s EyeQ
content-aware video compression solution optimizes the
video quality, even over constrained OT T networks. As
more high-resolution profiles are selected, less toggling
between profiles occurs with EyeQ. In particular, the EyeQ
solution reduces the network load during peak streaming
events, such as live sports.
Beyond enhancing subscribers’ QoE, Harmonic’s EyeQ
solution significantly reduced the OTT service provider’s
bandwidth and CDN costs by up to 50 percent, helping
them realize 100 percent ROI within a few months. It
accomplished this by measuring video quality according
to the human visual system (HVS). Traditional encoding
methods, such as CBR and CVBR, are ineffective at
measuring video quality because they often utilize too little
or too much bandwidth to sustain satisfactory video quality.
EyeQ encoding takes a different approach, leveraging a
real-time Harmonic psychovisual metric to continuously
assess video quality, according to the HVS, and focuses bits
where and when they matter most for the viewer. By having
the ability to measure and adjust video quality in real time,
the OT T service provider can achieve true constant quality.
Unnecessary bits are eliminated to ensure video quality
targets are met at the lowest possible bandwidth.
