More video with more features

In Forty years of video coding and counting I presented a short but intense history of ITU and MPEG video compression standards. In this article I will focus on how more functionalities got added to video compression over the years to MPEG standards and how the next generation of standards will add even more. The table below gives an overview of all MPEG video compression standards – past, present and planned. Those in italic have not reached Final Draft International…

Matching technology supply with demand

Introduction There have always been people in need of technology and, most of the time, people ready to provide something in response to the demand.

Hephestus duly complied. Still in the fictional domain, but in more recent years, Agent 007 visits Q Branch to get the latest…

What would MPEG be without Systems?

The most visited articles on this blog Forty years of video coding and counting and Thirty years of audio coding and counting prove that MPEG is known for its audio and video coding standards.

It is hard to acknowledge,…

The MPEG drive to immersive visual experiences

Introduction In How does MPEG actually work? I described the MPEG process: once an idea is launched, context and objectives of the idea are identified; use cases submitted and analysed; requirements derived from use cases; and technologies proposed, validated for their effectiveness for eventual incorporation into the standard. Some people complain that MPEG standards contain too many technologies supporting “non-mainstream” use cases. Such complaints are understandable but misplaced. MPEG standards are designed to satisfy the needs of different industries and what…
