MPAI standards

MPAI’s raison d’être is developing standards. So, including the word in the title looks like a pleonasm. But there is a reason: the word standard can be used to mean several things. Let’s first explore which ones. In my order of importance the first is “information representation”. If there were no standard saying that 65 (in 7 or 8 bits) means “A” and 97 means “a” there would be no email and no WWW. Actually there would not have been…

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…

Problem statement In the real world, a supply contract has at least three elements: the technical characteristics of the product the commercial terms, and the delivery date. These are vital elements for business. Indeed, the buyer would not be happy to discover that the product ordered has twice the volume, costs twice as much or is delivered one year later than the time agreed. The buyer who had known that before would probably have placed the order to a different…

MPAI basics

What it is MPAI – Moving Picture, Audio and Data Coding is an unaffiliated, non-profit, international association with the mission to develop data coding standards, predominantly using Artificial Intelligence. The MPAI Manifesto summarises the MPAI distinctive features. The main MPAI target is “data coding” that MPAI defines as the transformation of data from a given representation to an equivalent one more suited to a specific application, e.g., compression or semantics extraction. How it works MPAI develops standards using a rigorous…

Even the stars die – A guided tour

The Even the stars die is a book available on Amazon in electronic and paper form. It has several goals: To connect MPEG’s digital media standardisation with the traditional media standardisation To disclose why and how MPEG was conceived and the inside story of the first three “heroic” standards – MPEG-1, -2 and -4 To study the work done in some of the most important areas: video, audio, systems etc. To describe some of the unique MPEG characteristics To analyse the…
