I described the first steps in MPEG life that look so “easy” now: MPEG-1 (1988) for interactive video and digital audio broadcasting; MPEG-2 (1991) for digital television; MPEG-4 (1993) for digital audio and video on fixed and mobile internet; MPEG-7 (1997) for audio-video-multimedia metadata; MPEG-21 (2000) […]

Moving intelligence around
Introduction Artificial intelligence has reached the attention of mass media and technologies supporting it – Neural Networks (NN) – are being deployed in several contexts affecting end users, e.g. in their smart phones. If a NN is used locally, it is possible to use existing digital representation of NNs (e.g., NNEF, ONNX). However, these format […]
More standards – more successes – more failures
Introduction I have seen people ask the question: MPEG makes many very successful standard but many are not widely used. Why do you make so many standards? I know they ask this question because they dare not ask this other question “Why don’t you make just the good standards?”. They do not do it because […]
Thirty years of audio coding and counting
Introduction Obviously, the electrical representation of sound information happened before the electrical representation of visual information and so did the services that used that representation to distribute sound information. The digital representation of audio, too, happened at different times than video’s. In the early 1980s the Compact Disc (CD) allowed record companies to distribute digital […]
