What is MPEG doing these days?

It is a now a few months since I last talked about the standards being developed  by MPEG. As the group dynamics is fast, I think it is time to make an update about the main areas of standardisation: Video, Audio, Point Clouds, Fonts, Neural Networks, Genomic data, Scene description, Transport, File Format and API. You will also find a few words on three exploration that MPEG is making Video Coding for Machines MPEG-21 contracts to smart contracts Machine tool data.…

MPEG is a big thing. Can it be bigger?

Introduction Having become the enabler of a market of devices and services worth 1.5 T$ p.a., MPEG is a big achievement, but is that a climax or the starting point aiming at new highs? This is a natural question to ask for a group that calls itself “MPEG Future”. The future is still to be written and the success of MPEG will largely depend on the ability of those who attempt to write it. This article will try and analyse…

MPEG: vision, execution, results and a conclusion

Introduction In 1987, a few months before MPEG was the established, ISO TC 97 Data Processing became the ISO/IEC Joint Technical Committee 1 (JTC 1) on Information Technology. With this operation the data processing industry, renamed information technology industry on the occasion, was able to concentrate on a single Technical Committee (TC) all standardisation activities needed by that industry, including those “electrical”, until then the exclusive purview of IEC. Thirty-two years later, JTC 1 has become a very large TC,…

Who “decides” in MPEG?

If MPEG were a typical company, the answer to this question would be simple. Persons in charge of different levels of the organisation “decide”. But MPEG is not a company and there is no chain of command where A tells B to do C or else. Decisions are made, but how? As an autocracy, an oligarchy or a democracy? To answer these questions, let’s first see how the work in MPEG is organised. The convenor chairs the 3 plenary sessions.…

What is the difference between an image and a video frame?

The question looks innocent enough. A video is a sequence of images (called frames) captured and eventually displayed at a given frequency. However, by stopping at a specific frame of the sequence, a single video frame, i.e. an image, is obtained. If we talk of a sequence of video frames, that would always be true. It would also be true if an image compression algorithm (an “intra-frame” coding system) is applied to each individual frame. Such coding system may not…

MPEG and JPEG are grown up

Introduction A group of MPEG and JPEG members have developed a proposal seek to leverage the impact MPEG and JPEG standards have had on thousands of companies and billions of people all over the world. A few numbers related to 2018 tell a long story. At the device level, the installed base of MPEG-enabled devices was worth 2.8 trillion USD and the value of devices in that year was in excess of 1 trillion USD. At the service level, the…
