This week’s DLTJ Thursday Threads has just two pointers. First, a new volunteer web service to report problems with websites, which may be useful for not only our own sites but for the sites our patrons visit. Second, a nine-minute video that illustrates the reuse of themes and ideas in motion pictures across time.

If you find these threads interesting and useful, you might want to add the Thursday Threads RSS Feed to your feed reader or subscribe to e-mail delivery using the form to the right.

Thursday Threads: Gobs of Video, Memento Submitted, Everybody’s Digital, and Cell Phone as Credit Card

Another slow Thursday Threads week due to higher priority work duties taking precedent over scanning for trends. This week has a look at the explosion of video content uploaded to YouTube (which dovetails nicely with the Thursday Threads report two weeks ago about the record amount of internet traffic attributed to Google’s services), why the distinction between ‘digital natives’ and ‘digital immigrants’ should be dropped, how telecomm companies want a piece of the credit card business, and the movement of Momento to an Internet Draft.

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”

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.

Preserving Digital Video

Posted on by

My place of work is looking to acquire educational videos in a digital form with an eye towards long-term preservation. At this point we receive a physical form (preferably DVD, but sometimes VHS) and digitize it to a very lossy access format (RealMedia, in this case). With this change, we would get a preservation-worthy digital copy from the producer/distributor and forego the physical version.

There is quite a lot written on preserving video, but I wanted to distill the requirements down into statements that vendors could reasonably provide today. I think these are pretty sound requirements, but I’m looking for feedback. In particular, I’m not quite sure how to handle the transfer of closed caption text from the publisher/distributor; suggestions are welcome.

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.

Two Lectures on Copyright and Fair Use Today

Spotted in the Chronicle of Higher Education Online this morning is mention of two lectures by Wendy Seltzer that will happen today on the topic of copyright and fair-use doctrine. Here are the summaries and hCalendar events (the latter being useful if your browser and/or RSS reader understands the hCalendar microformat markup). Long-time readers of DLTJ might remember Professor Seltzer’s battle with the NFL over the overly broad statement about use of telecasts by posting a 33-second clip the SuperBowl on YouTube, which, at the moment, is still online.

A recent posting in the Chronicle of Higher Education “Wired Campus” section describes the new iTunes U portal, “a spot on the site that will collect college lectures, commencement speeches, tours, sports highlights, and promotional material, all available at no cost.” (If you have iTunes on your desktop/laptop, you can use this link to visit iTunes U in the iTunes Store.) Now, according to the Apple press release, “content from iTunes can be loaded onto an iPod® with just one click and experienced on-the-go, anytime, making learning from a lecture just as simple as enjoying music.”

Fair Use Versus the NFL with YouTube Caught in the Middle

Here is something to keep an eye on. Via the Chronicle of Higher Education, Wendy Seltzer, a visiting assistant professor at Brooklyn Law School and Fellow at the Berkman Center for Internet & Society at Harvard Law School, is demonstrating the concept of fair use to her class by going head-to-head with the National Football League. Specifically, she posted a 30 second video snippet of the NFL’s standard copyright statement to YouTube on February 8th and waited to see what would happen.

Update to ‘Embedded Web Video in a Standards-Compliant, Accessible, and Successful Way’

With the release of Microsoft’s Windows Media Player version 11, the Microsoft Media Server (MMS) protocol is officially no longer supported. (Except, of course, for the confusing/amusing footnote on that page that says ‘mms://’ URIs are “highly recommended” as a protocol rollover URL — only Microsoft can at the same time make something deprecated and highly recommended.) As Ryan Eby noted earlier this year, those generating ASX files for Windows Media Player need to adjust their scripts.
