I have been interviewed by the Chinese webzine LiveVideoStack. The questions were smart and gave me the opportunity to make my views known. Here is an extract of the questions on MPEG and of my answers. The full interview is here. LiveVideoStack: Your new book Even the stars die: The history of MPEG and how it made digital media happen has been published this summer, congratulations! Could you tell us what inspired you to write it? Leonardo: There is no…

Video compression patents – an obtuse story

  • Post author:
  • Post category:MPEG

People who look back at the MPEG-2 times as the golden age of video compression licensing have a point. For 20 years the ownership of an MPEG-2 Video and Systems patent was a licence to print money – just ask people in the industry. What those people don’t consider, however, is that the MPEG-2 licensing was not the first case of the new video compression licensing but the last case of the old consumer electronics licensing – just look at…

The second MPEG steps

Toward the end of the 1980’s, the television industry went crazy with digital TV: Among service providers you had the full spectrum of feelings: people yearning for it (satellite TV, cable TV and telecom), people exploiting it for different purposes (some terrestrial broadcasters), people fearing it (other terrestrial broadcasters) and people hating it (still other terrestrial broadcasters). Among manufacturers, the general feeling was of love (new markets and/or new products added to/replacing old products) mixed with fear (a competitor’s format winning the competition).…

The Genie that makes entertainment great

(By Dr. Jon Peddie PE, President, Jon Peddie Research, Tiburon, CA) Every time you watch a video or listen to music on your phone, computer, or TV, you use a data compressor-decompressor called a CODEC. By compressing the data representing the content you’re interested in, more people can use the already crowded networks we rely on every day, all day. The primary CODEC in use today is MPEG – the Moving Picture Experts Group. It has served us well since…

A funeral oration over the dead body of MPEG

  • Post author:
  • Post category:MPEG

Friends, world citizens, lend me your ears; I come to bury MPEG, not to praise him. The evil that men do lives after them; The good is oft interred with their bones; So let it be with MPEG. The noble ISO Hath told you MPEG was ambitious: If it were so, it was a grievous fault, And grievously hath MPEG answer'd it. Here, under leave of ISO and the rest For ISO is an honourable man; So are they all,…

The MPEG special forces: subgroups

  • Post author:
  • Post category:MPEG

MPEG started as a group tasked to develop a standard for interactive video on compact disc (CD). That was the great idea to make a standard that made sense. Telcos were not providing meaningful access to broadband. At most, you could get 64 kbit/s. Even today, after 30+ years of impetuous progress in compression, you don’t get much from a 64 kbit/s video. Therefore, for years and years, the videotelephone and videoconference business stagnated. Developing a standard for a consumer-application…
