Sad...
When we discussed compression to be used for HDTV in 1987 MPEG won because of
uniform performance across many image sequences and communication channels. It
is also survived as DVD compression format in early 90-th.

Leonardo code
Leonardo Chiariglione is widely regarded as the father of MPEG, as the
co-founder of the Moving Picture Experts Group over thirty years ago.
Now, it seems MPEG is no more, at least as far as he is concerned.
Speaking to informitv, he offered coded clues to the cause. As ever, I would be
interested in your views. Our CONNECTED VISION newsletter reaches an
influential group of regular readers. Feel free to forward this to your

MPEG is no more
14 June 2020
MPEG, the Moving Picture Experts Group, is no more. Leonardo Chiariglione, who
co-founded the group in 1988 and has chaired it since then, has resigned
because the MPEG group was closed. He suggests, rather enigmatically, that
there are those that would rather such an organisation did not exist, posing
the question of who benefits from such an outcome.
MPEG was formed as a working group of the International Standards Organisation
and International Electrotechnical Commission. The official designation is
ISO/IES JTC 1/SC 29/WG 11, that is Joint Technical Committee 1, Sub Committee
29, Working Group 11. Most people know it as MPEG and it has given this name to
a suite of 180 audio and video coding standards that are used worldwide.
The 130th quarterly meeting was due to take place in Austria in April but
instead was held as the first online only meeting of the group, with more than
600 participants. It seems it may be the last, at least the last to be chaired
by Leonardo Chiariglione.
A statement on the home page of the MPEG group, hosted at chiariglione.org,
says it was updated until 6 June 2020, “the day when the MPEG founder and
convenor Leonardo Chiariglione has resigned because the MPEG group was closed”.
MPEG
It seems that Sub Committee 29 decided to “erase” the MPEG group, although the
subcommittee will continue and so will its existing standards. Whether its work
will continue to have the same impact, or whether some form of MPEG initiative
will re-emerge outside the ISO process, remain to be seen.
After a degree in Electronic Engineering from the Polytechnic of Turin in 1967,
the father of MPEG gained a PhD in Electrical Communication from the University
of Tokyo in 1973. He launched the ISO/IEC Moving Picture Experts Group in 1988,
recognising the need for an organisation that would create digital media
standards so that consumers could seamlessly communicate and enable a global
market of interoperable products, services and applications.
Since then, MPEG has become almost synonymous with digital video compression,
much as JPEG, from the Joint Photographic Experts Group, has become synonymous
with still image compression.
However, there are many competing standards for advanced video compression and
the field is flooded with intellectual property claims, meaning that adoption
is encumbered by patent licensing issues, resulting in cost, complexity and
uncertainty.
The Alliance for Open Media, or AOM, was formed in 2015 to develop a
royalty-free alternative. The founding members were Amazon, Cisco, Google,
Intel, Microsoft, Mozilla, and Netflix. They have since been joined by Apple,
ARM, Facebook, IBM, Nvidia, Samsung and Tencent as governing members, with many
more general members.
Alliance for Open Media
The Alliance requires technology contributors to disclose all patents that may
be relevant and to agree to a royalty-free patent license. It will release
video codecs as free software under an open source licence.
Its first project was to develop AV1, a new open video codec and format as a
successor to VP9 and a royalty-free alternative to HEVC, or H.265, otherwise
known as MPEG-H Part 2, the successor to AVC, or H.264, otherwise known as
MPEG-4 Part 10.
HEVC has had some success in the broadcast industry, as the successor to AVC
and MPEG-2, but has seen less adoption in online usage, where some of the most
powerful players are involved in the Alliance for Open Media, although support
for AV1 remains patchy.
Speaking to informitv, the father of MPEG was characteristically philosophical.
“MPEG is no more,” he said. “An answer may come if you connect the dots guided
by the maxim ‘cui prodest?’” In other words, who benefits? The phrase is often
used to suggest that the perpetrator of a crime stands to benefit.
“I had this vision 33 years ago,” he said. “I took care of the baby and then
the baby grew up. I had a lot of personal satisfaction from that.
If the industry thinks they don’t need that baby, so be it.”
