A feature like this is key, especially at this stage, to ensure
your encoded video is compatible with streaming platforms
and video decoders that do not yet support HEVC.
Despite the somewhat limited support for HEVC, there are
still a few ways to take advantage of it now, and Cube makes
that easier than ever before.
One great example is IP video routing over existing network
infrastructure. The greater efficiency allows for better video
quality that is much closer to traditional HD video bitrates,
all while on standard, ubiquitous Ethernet networks. Teradek
offers encoders and decoders, and has also been tested and
verified with other manufacturers’ current HEVC offerings.
HEVC also offers many benefits for bonded cellular
broadcasting solutions such as the Teradek Bond, which utilizes
the Cube’s video encoder.
Since cellular bandwidth
is constantly variable and
lower bitrates are often
required to ensure video
reaches its destination
without issue. With HEVC,
you can achieve much
higher-quality video at
lower bitrates than ever
possible with similar H.264
systems. The challenge
continues after video has
been successfully delivered to the cloud, as most web platforms
lack support for the new codec. Teradek solved this problem
by adding on-demand transcoding to its Core IP video
Teradek’s Core platform enhances Teradek codecs by offering
multiple cloud-based features including archiving, monitoring,
remote configuration, routing, and now, transcoding. With
Core’s new transcoding engine, Teradek users can take
advantage of HEVC’s benefits and H.264’s far-reaching support.
After streaming to Core—via bonded or a direct connection
to the platform—live video can be transcoded into H.264 for
delivery to any online video platform or H.264 decoder.
For Apple users, HEVC support and the new Cube encoders
open up even more possibilities. Teradek’s various apps, including
the Live: Air suite of live production tools, will allow independent
content creators, schools, life streamers, and others to access the
benefits of HEVC without the price tag of other solutions.
SHOULD I ALWAYS STREAM IN HEVC
AND AT THE HIGHEST RESOLUTION?
While the Teradek end-to-end HEVC solution opens up
the door for picture perfect HD and Ultra HD streaming over
local networks and the Internet, there are still some factors
dictating just how high the quality can go.
Despite HEVC’s ability to cut AVC bitrates in half and
maintain video quality, good quality 4K video still requires 20
to 30Mbps. To achieve the absolute best quality, that number
will be higher still. This sort of bandwidth can be prohibitively
expensive for live production companies and other remote or
fixed encoding applications. Bandwidth at fixed locations is
often tough to guarantee, and the cost of short-term dedicated
bandwidth at venues and conferences will easily approach
tens of thousands of dollars.
Another major consideration is the viewers. At bitrates as
high as 20 or 30Mbps, many home internet connections would
struggle to stream the content without buffering or stuttering.
4K video, though approaching commonplace in production
environments, is still relatively new and and uncommon for the
average home. Few households have a 4K capable television,
computer, or smart device, so delivering content at that
resolution, especially live, isn’t strictly necessary. Just as HEVC
must deal with the inertia of widespread adoption, stream
bitrates and resolutions must contend with the availability
of cheap, reliable bandwidth, and 4K viewing equipment.
HEVC IS HERE AND IT’S
NEARLY READY FOR PRIMETIME
HEVC is the future, and the benefits it brings to streaming
video are undeniable. End-to-end solutions like Teradek’s
Cube, Bond, and Core, along with the upcoming addition of
HEVC support in iOS, allow broadcasters and enthusiasts to
take advantage of the immense bandwidth savings HEVC
offers without the delivery problems that come with it. The
question is no longer whether it’s time to go live in “265,”
it’s how soon will you start?
Teradek manufactures wireless video devices for remote video
capture, camera control, real-time monitoring, color correction and
webcasting. For complex IP video systems, Teradek’s cloud-based
workflow management platform allows users to remotely operate a
fleet of Teradek encoders in real-time from anywhere in the world.
All Teradek products are designed and manufactured in the USA.
The Teradek Bond module is attached directly to the Cube,
enabling a more robust, bonded-cellular bandwidth solution.
The Live:Air app for iOS is a powerful video switching and studio application
that allows you to bring in video sources connected to Cube as wireless feeds.
Teradek’s Core platform allows users to create a
robust ecosystem for a complete web streaming
and point to point workflow.
