Starting from the “marginal” idea of compressing digital video to fit it in the low throughput of 1.4 Mbit/s of a CD, MPEG had to develop newer areas of expertise...
A free translation of the fake Latin proverb “Homo homini lupus, femina feminae lupior, sacerdos sacerdoti lupissimus” could go like this: man behaves like a wolf toward another man, a...
In primitive societies every able individual was capable of making for himself all that was needed for a living: bows, arrows, shoes, tents, pottery, etc. From early on, the social...
Advancement in society – and ingenuity in developing appropriate technologies – created written works. If one takes the remaining samples of old written works, it is easy to imagine that...
Being able to own “rights” to something is a fundamental concept of living beings: ants own the “right” to suck aphids, but they are “obliged” to feed them, if they...
The MPEG-1 standard was an offspring of its age. Just as CD Audio had no content protection provision – something the music industry came to regret – the MPEG-1 standard...
Electronic computers were a great invention indeed and the progress of the hardware that has enabled the building of machines that get smaller and smaller year after year while, at...
My encounter with IT as a (business) tool for the AV world happened towards the end of the MPEG-2 development and was greatly enhanced by my participation in the DAVIC...
Devising methods to interact with machines and the very act of interacting with them are often endeavours with varying degrees of challenge. Playing a musical instrument may require years of...
Most of what has been said so far concerns audio and visual information generated in the real world and reaching human senses either directly or through a more or less...
Today the word “Internet” has become an integral part of everyone’s everyday vocabulary. So it is understandable that many people, with grounds or without, claim to have had a role...
Already in 1991, when MPEG-1 was maturing and the definition of MPEG-2 was rapidly progressing, I had begun to wonder whether there was a scope for work beyond what had...
Cliff Reader, who had joined Samsung after leaving Cypress, was appointed as chair of a new AHG with the task of identifying applications and requirements of the new project that...
Many papers and books explain the MPEG-4 standard using the figure below, originally contributed by Phil Chou, then with Xerox PARC. This page will be no different :-). We will...
MPEG-4 Visual provides a coding algorithm for natural video that is capable of operating from 5 kbit/s with a spatial resolution of QCIF (144×176 pixels) scaling up to bitrates of...
MPEG-4 Audio provides complete coverage of the bitrate range of 2 to 64 kbit/s. Good coded speech is obtained already at 2 kbit/s and transparent quality of monophonic music sampled...
The MPEG File Format has been designed to satisfy a set of requirements, some of which are listed below Binary assets Hierarchical structure Backward- & forward-compatible Suitable to hold timed...
During the development of MPEG-4, several liaison statements were sent to ITU-T suggesting to work together on the new MPEG-4 Visual standard and even on the MPEG-4 Audio standard, specifically on...
