There is more Digital & Multimedia Evidence (DME) than any other type of evidence today.
Working together we've expedited tens of thousands of criminal investigations. Learn more

I just returned from another great week of DME training at our office out on the east coast last week. One of the themes I've come to recognize through my travels teaching the fundamentals of DME Processing, is that even some of the most seasoned technicians and analysts don’t really understand the significance of hardware to accurate and proper processing of DME. It’s completely understandable why, given the marketing messages of some DME vendors, the fact that we're all constantly asked to do more with less, and the rate of related technological advancements.

Understanding video standards is fundamental to aspect ratio correction. Back in the predominantly analog days we had three main standards referenced or used for most video recordings; NTSC, PAL, and SECAM. Then in the early ‘90’s came the first digital multimedia frameworks to reach the average consumer; QuickTime and, shortly thereafter, Video for Windows (VfW).

Today we have dozens of multimedia frameworks, digital video and digital display standards, all of which lead to a great deal of confusion regarding the plethora of acronyms and what they truly mean. AVC or H.264? HEVC or H.265? CIF or SIF? Don’t even get me started on the profiles and parameters available for each standard, as the combinations are truly mindboggling. When it comes to proper Display Aspect Ratio (DAR) though, it really boils down to “Are the originally recorded pixels square or non-square?”

$5.00/gallon? $10.00/gallon? Maybe Web meetings will be more socially acceptable in the business world when gas prices have completely crippled our economy and there's practically no such thing as a small business anymore. I, for one, certainly hope we don't have to wait and see.

Online meeting services are certainly nothing new, yet every time gas prices reach a new high they're all the buzz, and rightfully so. Unfortunately, after a few months of feeling like you're being robbed at the pump, they seem to slip off the to-do list for most. Why is that?

HP made some big product announcements today that I've been patiently waiting for.  My patience is wearing thin though, as the two devices I am most anxious to get my hands on won't be out until this summer.  I was a bit peeved earlier when I heard that, but there's no doubt I'll wait rather than jump ship to another OS (he says as he writes this post from his original Palm Pre).

For those who have spent any time with all of the major mobile operating systems, it has been clear from day one webOS has the most potential.  True multi-tasking is a biggie, and nobody does it better.

Yes, I'll wait for the Pre 3 and HP Touchpad, but I'd better get a nice loyalty discount HP! 😉

3D graphics have, for many years now, been based on the idea of polygons -- flat shapes fitted together to form three dimensional objects. There have been some experiments with other approaches -- volumetric 3D pixels or "voxels" became quite popular with some developers in the late 90s, but for the most part, polygons were seen as the way forward. New consoles and graphics cards were marketed based around how many polygons they could push around the screen at once, and it looked like the industry had settled on a good solution.

I just wanted to thank all who attended, planned and supported the LEVA 2011 Training Conference. I truly enjoyed the training and community discussion sessions.  It was great seeing everybody and meeting new peers, and in hindsight only wish I could have stayed for the evening events and more peer networking.  As always, I truly look forward to next time.  All the best. - LC

The browser war rages on and new versions are being released at a break-neck pace. Unfortunately, for Web developers at least, each new version seems to introduce multiple changes that not only affect how pages are displayed, but how and if various features in a site will even function. It's madness I tell 'ya.

Anyway, since I started using Safari as my primary browser, I've been looking for another WYSIWYG editor for our members, because in Safari with TinyMCE set as your editor members couldn't use the Submit or Cancel buttons when attempting to submit articles, news, or events. Long story short I've found one, I'm using it right now, and I'm diggin' it so far.

 

A couple weeks ago I was up in Vancouver to teach Ocean Systems’ DVR Assessment & Video Recovery training course, which was hosted by the Vancouver Police Department. Many thanks to our host agency and students, as it was another great week of training and information sharing. Next week I’ll be in Miami to provide a free seminar on Digital Video Evidence on Monday morning, followed by our 3-day DVR Recovery training course which will run Tuesday through Thursday.
