The Rise and Fall and Rise of JPEG2000

The Rise and Fall and Rise of JPEG2000

Currently a niche codec, recent enhancements to the JPEG 2000 standard speed it up by 10x and will propel it into the mainstream.

Track: Open Media devroom
Room: UB2.147
Day: Sunday
Start: 10:00
End: 10:25

JPEG 2000 was developed to replace the very successful JPEG standard, but it has instead remained a niche code. With recent updates to the standard speeding up decode by 10X, is world domination around the corner ? This talk will describe many of the sophisticated features that JPEG 2000 offers, and discuss why a 20 year old standard may be the codec of the future.

Released in 2000 as a potential replacement for the wildly successful JPEG standard, JPEG 2000 is a versatile codec with many sophisticated features including:

Superior compression at low bit rates
Storage of multiple resolutions in a single bitstream
Precise rate control without re-compression
Lossy and losssless compression
Progression by resolution, component, spatial region or quality

It is an essential codec in medical imaging, digital cinema and remote sensing. However, due to its high complexity, it has remained a niche codec that never gained the popularity of its predecessor.

All of this is about to change with the recently released High Throughput JPEG 2000 standard that speeds up the codec by up to 10x, while leaving almost all of its features intact. This will propel it into the mainstream, particularly in broadcast and digital cinema.

I will talk about the history of JPEG 2000, give an overview of its features and discuss the upcoming changes. I will also talk about current and planned GStreamer support for JPEG 2000.
