The new JPEG 2000 work items have been introduced partly as a direct result of the active part taken by European delegates to the ISO/JPEG meetings.
They take the basic JPEG 2000 standard and add new features and capabilities in:
- Security: security is a growing concern for owners of digital media content. The JPEG committee has started a new Part 8 to the standard, referred to as JPSEC in order to ensure the security of transaction, protection of contents (IPR), protection of technologies (IP), and to allow applications to generate, consume and exchange JPEG 2000 secured codestreams.
- Interactivity: this covers the opportunities for client / server computing, where the server or the client can control and optimize the data flow over a network to meet application needs. As well as allowing for optimized image communication to different platforms, this can allow the re-ordering of JPEG 2000 codestreams - for example to handle region of interest or low resolution delivery as a priority. Named JPIP by the JPEG committee, this interactivity is covered in a new Part 9.
- Volumetric: volumetric and 3D images are needed in many applications, including medical imaging (e.g., CT, Computer Tomography), biology, geology, and artwork representation (sculptures, objects). A new Part 10 called JP3D has been started for this work area.
- Wireless: transmission errors due to noisy channels may adversely impact image quality and even the proper decoding of a JPEG 2000 codestream. Examples of applications include domains like 2.5G (GPRS), 3G (UMTS), DRM (Digital Radio Mondiale), wireless LAN and others. The JPEG committee has decided to produce a new Part 11 to the standard to cover this topic, referred to as JPWL.
