AAF Explanations from...the AMW Association

I apologize for the break in postings...I've been on assignment.

As we all approach the world of universal project and media structure...more or less, it's always good to review why in the world we are doing this to ourselves and at least remember that the whole idea was ultimately to make everything easier.






The Advanced Media Workflow Association is the name of the body that is the keeper of the AAF and MXF standards that manufacturers seem to typically adopt, but not completely or in a standard way...which of course leaves the main role of these standards (transportability between applications and environments) absent in many circumstances.

Eventually however, we all know that intellectually the adoption of open standards in a uniform manner will benefit the entire production community and therefore we'll hold out hope that some day manufacturers may actually agree and implement accordingly...

In the meantime, the AMWA has an excellent AAF explanation document available for those of you interested in a better understanding of what AAF is ...and isn't.

Want to hear about the REAL beginning of the Internet?

Vint Cerf (pictured) was around way back when the idea of what we now know as the internet was being visualized and being concept-tested. I know it isn't related to imaging directly, but this is an interesting presentation by a really engaging speaker on a topic that affects all of us.

Trust me, it's a great tech war story, you'll like it. It runs an hour and you can download it and watch it when you have some wait time.

...on one of my favorite sites, The Research Channel.

General Knowledge: Quick Visual Guide to RAID Levels

JetStor has (in my opinion) one of the most easily understood visual guides to RAID Levels and how they work.







The selection buttons are a little small, but they're just above the illustration.

Enjoy.

Dalsa announces a 48 megapixel image sensor.

Dalsa has introduced an image sensor that is 48mm x 36mm and has a photosite lattice of 8000 x 6000. The CCD is a Bayer pattern in the modern RGB configuration. (See the post "Bayer Sensors...Patented in 1976...")

The technical paperwork in here. The claim is that even though each photosite is reduced in size by 30% from the previous generation sensor, the signal-to-noise ratio improved by the same amount.

Dalsa also has an excellent tech paper on how image sensors work here.

Luckily our data storage expands as voraciously as our pixel counts...

More excellent reference material: CCD vs CMOS image sensors

I'm dusting off all my favorite reference material and sharing it with you this Holiday Season.

The fine people of Dalsa have some of the most detailed CCD vs CMOS sensor comparisons I've seen. Make sure to also check out the two links on the right side that take you to additional papers on the topic in PDF form.

More news from Dalsa tomorrow...a small hint...pixel count.

Enjoy.
