Description
Possessing the
highest real-time transcoding density on the market and any-to-any format support,
the Harmonic Electra® XT Xtream™ transcoder delivers significant CAPEX and OPEX
savings and accelerates time to market for operators faced with fast channel
lineup growth and a rise in
multiscreen applications.
Now more than ever,
digital TV delivery is changing at a rapid pace, with an increasing number of
channels to broadcast, more formats to support and an explosion in the range of
multiscreen devices such as tablets, smartphones and connected TVs. Service
providers have to tackle these challenges while continuing to increase their
subscriber base, develop new web TV business and sustain average revenue per user.
The Harmonic Electra XT transcoder helps operators succeed in this new
paradigm.
A cost-effective
appliance for live content transcoding, the Electra XT provides high-density
and scalability for traditional broadcast over cable, IPTV, DTH and DTTV, as
well as for multiscreen applications.
Any-To-Any Format Support
The Electra XT receives
compressed video over IP streams and can transcode audio and video content from
any format to any other format. For video, the device supports MPEG-2, MPEG-4
AVC and HEVC decoding and encoding in SD and HD resolutions. A wide range of
audio codecs is also addressed, including MPEG-1 Layer II, Dolby® Digital
(AC-3), Dolby Digital Plus (E-AC-3), AAC-LC and HE-AAC v1/v2 in mono, stereo and
surround modes.
Highest Density & Scalability
Leveraging extensive
experience and innovation in video compression algorithms, the Electra XT
provides best-in-class transcoding density with up to 288 channels per
platform, depending on codec and resolution. It is designed with efficiency in
mind, and supports operator business growth with a modular architecture that
accommodates up to nine hot-swappable audio/video processing modules. Each
module can transcode a mix of channels independent of their codec (MPEG-2,
MPEG-4 AVC or HEVC), resolution (HD, SD and low resolution) and frame rate (up
to 60fps) through per-channel software licensing.
The high-density
benefits of the transcoder significantly reduce rack space and minimize power
consumption. A flexible web-based graphical user interface facilitates the
configuration and supervision of hundreds of simultaneous transcode channels.
Beyond Transcoding
The Electra XT is
much more than a basic high-density transcoder. To bring added value to
workflows, the unit embeds efficient and advanced features, including
user-defined text and logo insertion, and manual and automatic loudness control
on transcoded audio channels. For satellite, terrestrial and cable
applications, the Electra XT supports internal statistical multiplexing to meet
end-user demand for video quality while optimizing bandwidth. For multiscreen
applications, adaptive bitrate encoding is supported. Video can be delivered to
an external packager,
or it can be internally scrambled and packaged in the Apple® HLS, Microsoft® Smooth Streaming and MPEG-DASH formats.
