HEVC Compression Standard Moves Forward
– Twice the Video Quality at Same Bandwidth
– Or, Twice the Streams at the Same Bandwidth
The Moving Picture Experts Group (MPEG) announced in August a
draft of the HEVC standard, which, if adopted, could cut by
50% the bandwidth needed for video without a decline in video
quality. It doubles the compression of the current H.264/AVC
The compression scheme, when carried to fruition, will have a
major and positive impact on OTT services which could offer
better video quality and reduce buffering.
It would help telcos who are struggling to meet the speeds the
cablecos are offering. It might postpone the need for them to
deploy all-fiber networks.
HEVC would also help pay TV services and over-the-air
broadcasters who could offer higher video quality such as 4K
over the same bandwidth or twice as many channels in the same
bandwidth. It will also help cellcos who are currently limited
in the volume of video they can stream to smartphones and
Companies involved in the development of the HEVC standard are
pay TV and broadband service providers, computer makers and
consumer electronics manufacturers.
The industry is itching to get HEVC implemented:
– Qualcomm demonstrated a HEVC decoder running on an Android
tablet with its Snapdragon S4 dual-core processor on February
29, 2012 at the 2012 Mobile World Congress. It showed a 50%
bit rate reduction compared to H.264/MPEG-4 AVC.
– In August 2012 Ericsson announced the world’s first HEVC
encoder, which is aimed at real time encoding of video for
delivery to mobile devices.
– In August of this year Allegro DVT announced two HEVC
broadcast encoders that stream live IP video.
– In September Vanguard Software Solutions (VSS) announced an
x86 PC software based HEVC encoder. It can encode 1080p
(1920×1080) at 30 frames per second (fps).
– In September Rovi announced that a SDK for HEVC that
includes a decoder, encoder and transport multiplexer for
Windows, Mac OS, Linux, iOS and Android.
– In September ATEME demonstrated a HEVC encoder that encoded
video with a resolution of 3840×2160p (4K) at 60 fps with an
average bit rate of 15 Mbps.
