JPEG2000 Summit at Library of Congress, May 12-13, 2011

It has been years since I’ve done meaningful work with JPEG2000, but I still try to keep tabs on what is happening in that community. In that vein, Rob Buckley — formerly of Xerox Research and now on his own with a consulting business — pointed me to an announcement about a JPEG2000 Summit happening at the Library of Congress next month.

Latest Views on JPEG2000 for Presentation and Archiving

Earlier this month, the JPEG 2000 Implementation Working Group, the Wellcome Trust Library, and the U.K. Digital Preservation Coalition hosted a free one-day seminar called JPEG2000 for the Practitioner. The presentation slides are now linked to the seminar program and is a short report of the event by Christy Henshaw of Wellcome Library. The presentation slides by themselves carry a great deal of depth even without a recording of the audio. In particular I can recommend “What did JPEG 2000 ever do for us?” by Simon Tanner and “JPEG 2000 standardization – a pragmatic viewpoint” by Richard Clark. As brief introductions to where we’ve been with JPEG 2000 and where we could go.

Broadcast JPEG2000 Alliance Announced

Today at IBC2009 Fast Forward Video (FFV) announced the launch of the JPEG2000 Alliance, “a consortium of broadcast industry leaders dedicated to ensuring that JPEG2000 continues to develop into a leading compression standard.” According to the press release:

In addition to developing their own JPEG2000 technologies and products, these companies will collaborate to ensure widespread acceptance, deployment, and support of the compression standard for the benefit of the media and video industries. Activities will be centered on educating and creating awareness about the benefits of JPEG2000, promoting interoperability between standards and system devices, and promoting the development of tools by members and industry peers.

Use of JPEG2000 for Broadcast Video Transmission

Although my day-to-day work takes me farther away from working with digital collections in general and JPEG2000 specifically, I still have a Google News search set up looking for hits on JPEG2000 topics. An entry appeared yesterday that gives some interesting insight into how motion JPEG2000 is being used in broadcast video transmission: “HBO Opens T-VIPS Video Gateways: Norweigan Vendor Helps Premium Net Ship Content Coast to Coast

LANL Releases Open Source JPEG2000 Image Server

The lead article in the September/October issue of D-Lib Magazine release yesterday is on djatoka, the open source JPEG2000 Image Server from Los Alamos National Laboratory. The authors, Ryan Chute and Herbert Van de Sompel describe their effort in the article abstract:

Survey Responses Sought: JPEG2000 for Still Images

David Lowe, Preservation Librarian at the University of Connecticut, is coordinating a survey of JPEG2000 use for digital imagery. The survey asks questions about the use of the JPEG2000 file format (for archival purposes or for access systems), tools used (both JPEG2000 toolkits and software that embeds JPEG2000 toolkits), and considerations of mathematically lossless versus visually lossless compression settings.

This is his announcement:

I am writing to solicit your help with a survey of library-related digital project staff regarding the implementation of the JPEG 2000 standard for digital images (specifically still images and not motion). We estimate that this task will take approximately 15 minutes of your time. It is available now at: http://www.surveymonkey.com/s.aspx?sm=WXFAJwyRNZZilRWzrnum_2fw_3d_3d

Archiving in Practice with JPEG2000: ALA Annual Conference, June 29, 8am-10am

The JPEG2000 in Archives and Libraries Interest Group of the LITA division of ALA is pleased to present a program on Archiving in Practice with JPEG2000 on Sunday, June 29th from 8am to 10am in Ballroom E, Anaheim Convention Center.

The lead presentation will be given by Justin Dávila, Digital Media Workflow, Business and Technology consultant. The formal presentation will be followed an invitation to the audience to present five-minute lightning talks on the topic of JPEG2000 for cultural heritage archiving and access. More details can be found in the announcement on the j2kArcLib.info website.

JPEG2000 to Zoomify Code4Lib Lightning Talk Video Now Available

Thanks, Noel, and everyone else who made the video editions of Code4Lib 2008 presentations possible. I just had a chance to notice that the video from my JPEG2000 to Zoomify Shim lightning talk was online:

Some updates since the post and the presentation were first done. The code that exists in the source code repository now was refactored to use JJ2000 as part of the Sun ImageIO package. We were seeing non-threadsafe problems with Kakadu and thought that using the multithreaded ImageIO package would help. Unfortunately, even with extensive caching, it did not. My next task is to bring Kakadu back into the picture using the threadsafe JNI implementation that is part of the ImageIO-ext project to see if that helps.

JPEG2000 to Zoomify Shim — Creating JPEG tiles from JPEG2000 images

This is a textual representation of a lightning talk done on Feb 26th at Code4Lib 2008. When the video of the talk is up (thanks, Noel!) I’ll link it here, too. The video is now available, and that article includes an update on progress since the this article was posted.

Wireless JPEG2000 Video and a Paper on How JPEG2000 Works

Two items of recent note in the JPEG2000 world. The first is the announcement of “the world’s first fully integrated wireless HDTV” that uses JPEG2000 over the air:

The High Definition LCD TV, featuring Pulse~LINK’s integrated CWave® UWB Wireless HDMI technology, will be on display for the first time at the 2008 International Consumer Electronics Show (CES) in Las Vegas, Nevada, January 7-10. […] With the integration of CWave® Wireless HDMI, digital display products can be mounted anywhere in the room without needing to run data cabling from the TV to the content source, such as a DVR, Blu-ray or HD DVD player, or a live cable or satellite feed. Video data is encoded using the JPEG2000 video codec, the same codec used by movie theaters for “Digital Cinema,” providing a secure high quality HD experience. Pulse-LINK’s Wireless HDMI solution is engineered to be equivalent in both content protection and visual experience to a wired HDMI connection.
