Image Compression
for Video Transport
Image Matters unveils ORIGAMI Hardware Accelerated Video Ecosystem at 2016's NAB Show...
HD, 4K, and 8K Resolution
HD resolution has been massively
adopted over the last 15 years.
Higher resolution of 4K was
originally driven by digital cinema,
but it also became a new TV broadcast
standard in 2013 (SMPTE and EBU).
The next step after the 4K is
UHDTV-2 (8K). 8K at 120 frames per
second was originally developed by
NHK, the Japanese public broadcasting
organisation, becoming an ITU
standard in 2012. 8K is emerging
namely with the Japanese effort in
the road to the 2020 Tokyo Olympic
Games.
This
very
demanding
resolution of 7680 × 4320 is 16 times
larger than HD image (33 million
pixels/frame).
Current Studio infrastructure
Studio infrastructures for video
signal transport are still mostly based
on HD-SDI (1.5Gbps) and 3G-SDI
(3Gbps) coaxial cables. 12G-SDI to
carry 4K in a single interface is just
starting to be adopted.
The transition towards video
transport over IP is also starting,
with only some pioneers having
already switched toward full-IP
infrastructure. Moreover, IP transport
still requires a lot of standardisation
and interoperability efforts.

codecs. There are multiple candidates,
such as JPEG 2000, TICO, and HEVC.
High Efficiency Video Coding (HEVC)
is a new standard for beyond HD
video, but mainly targets broadcasting
and distribution of content to
consumers at very low bitrate. HEVC
is based on DCT transform which
makes it subject to rapid video quality
degradation over successive encodingdecoding cycles. Consequently HEVC
does not constitute an ideal option for
studio-quality video transport.
For the last 10 years, JPEG 2000
has been commonly used in studio for
HD contribution over IP. It preserves
image quality and offers a low latency,
while keeping affordable codec prices.
JPEG 2000 in 2K and 4K resolutions
is also used for digital cinema as
it delivers a pristine quality to the
highly-demanding cinema audience.
JPEG 2000 and TICO compression
schemes as intra-frame codecs based
on wavelet transform have been
specifically designed as alternatives
to uncompressed systems for live
production over IP or over SDI. Used
as "mezzanine" compression, they
are visually lossless, low-latency, and
robust to multiple cycles of encoding
and decoding without degradation,
which is necessary for the production
workflows.

Video Compression
Practically, broadcasting of high
bandwidth and storage of big volumes
of 4K or 8K video require good,
visually lossless, and effective video

Video Transport Infrastructure
8K60p video requires a minimum
of 48Gbps. Current SDI and Ethernet
practices or standards are not able
to handle 8K. Today, the only way to

transport uncompressed 8K video is to
use multiple SDI cables in parallel, or
to use expensive 40 Gbps or 100 Gbps
Ethernet network connections.
Additionally, 8K coding is usually
solved by multiple HD equipment
with independent HD codecs, SDI and
network connections. No 8K interfacebased on mezzanine codecs is being
proposed today.
With light compression ratio, TICO
can offer a way to carry 8K over a
single 12Gbps SDI cable or over a 10G
Ethernet port. With slightly higher
compression ratio, JPEG2000 allows
users to carry multiple 8K streams
and to use currently installed studio
infrastructure based on 3G-SDI or 1G
Ethernet.
The Ideal Connectivity
To be future-proof, manufacturers
have to create devices supporting
HD-SDI, 3G-SDI, 6G-SDI, and 12G-SDI
and which are ready for the upcoming
24G-SDI, as well as interfacing with
10G Ethernet, 4×10GEthernet. They
also have to be prepared to address 25
G Ethernet, 4×25G Ethernet, and 100 G
Ethernet.
These devices also have to integrate
light compression codecs such as
TICO, or studio-quality strong codecs
like JPEG 2000 and, if addressing the
distribution to end-viewer, MPEG2,
MPEG-AVC, and HEVC codecs.
These interfaces also must integrate
transport format wrappers like SMPTE
2022, TR01, TR03, or for file-based
workflow, IMF, DCP, etc.

8K resolution is 16 times larger than that of HD

A first step in that direction is
provided by Image Matters through its
innovative ORIGAMI Module.
Hardware Accelerated
Video Ecosystem
With ORIGAMI, Image Matters
offers
innovating,
cutting-edge
technology for video transmission
over high-speed networks and SDI
infrastructure, easing the access to
single links connection for 4K and 8K
formats at high frames rates.
Grouping
together
extensive
experience in image compression,
video
interfacing,
network
management, and electronic board
design, together with multiple
partners from all around the world,
Image Matters introduces the
ORIGAMI Hardware Accelerated Video
Ecosystem at this year's NAB Show.
Based on a modular architecture
and provided with powerful tools,
ORIGAMI empowers OEMs with easy
access to current and future video
infrastructure needs. The ORIGAMI
product range includes processing
modules built around powerful Xilinx
FPGAs
and
application-oriented
carrier boards. The module is
populated with pre-validated IPCores to interface SDI and Ethernet
signals, and to process video streams
including TICO, JPEG 2000, and HEVC
compression kernels, as well as
SMPTE 2022 and TR03 wrappers. Each
module is able to process 4K60p in
JPEG 2000 and 8K 60p in TICO.
