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.
