The Journal Gazette reports that the Fort Wayne police have released security video from an armed robbery that occurred last week at the McDonald’s at 1103 Goshen Ave. in Ft. Wayne, Indiana

The video is available on YouTube and is also playing on our home page. Anyone with information is asked to call Crime Stoppers at 436-7867 or 1-800-237-7867. All information is confidential.

Improper cabling is the most common mistake made when setting up home theatre systems. Periodically I'll get a call or email from a friend or family member who just brought home their new HDTV, and the picture just doesn't seem right. More often than not, the obvious difference in picture quality from when you watched it in the store to when you set it up at home is the direct result of improper cabling. So here's the skinny, short and sweet.

ALWAYS USE COMPONENT VIDEO CONNECTIONS
Component video provides the best quality image, as it separates the video signal into three channels (red, green, blue), subsequently providing more bandwidth per channel. Audio is carried separately, usually via stereo RCA connections. For true HDTV you'll need to use the component connection, and its obviously ideal for other video sources as well (such as DVD players/recorders).

Magnetic tape has been used as a storage medium continuously from one of the first contemporary computers onwards -- the UNIVAC, in 1951. That gives it 60 years of unbroken use, from gigantic reel-to-reel rolls of the stuff to tape cartridges that might one day hold 70 terabytes apiece.

Broome County DPW Web Page - March, 2020

Turns out, pretty damn fast. Way faster than I would, on anything, let alone a croch rocket.

Many of my favorite memories of my time in Broome County involve Harry. Like when he and I where taking hang gliding classes together in the evenings, and those dark & early morning hours on the weekend.

My favorite though was almost dying with him, which I would gladly do to this day, if given an option of how to go out. We were riding motorcycles. Enough said.

Okay, maybe not enough. You should know that my career as an amateur daredevil started very young. I began riding our Honda 50 at 5 years old, and just kept trying to think of more spectacular ways to nearly kill myself from then on.

Harry has me beat. Hands down.

Our Executive office spoke with Harry about us riding motorcycles together, taking hang gliding lessons together, etcetera.  Thier comment to him was:

"There's a reason the President & the Vice President don't ride in the same vehicle together, Harry."

It has been an amazing and incredibly busy summer for me and my family. I briefly mentioned in a previous post that we moved at the beginning of summer, which was entirely unplanned by the way (!), and no sooner than that was behind us more curve balls were thrown our way. We’ve been so busy swinging as hard as we can to try and knock those balls out of the park that it’s impacted how active I’ve been here on DME Resources. The short of it is this, I am still committed to our online training library and hope to be posting regularly here again soon. With that said, two quick topics to discuss.

The multimedia evidence community has been really buzzing the last couple of years in regards to how useful FFmpeg and Libav can be for dealing with proprietary video formats. Both tools are extremely useful in several aspects of a forensic DME workflow. With that said, however, whether it’s FFmpeg, Libav or another 3rd party tool, there are limitations and causes for concern when using them to process proprietary video file formats.

A series of Key frames (K) and Delta frames from a video stream.

Lossless trimming is the ability to trim, cut or extract segments of audio & video without re-encoding the original multimedia streams, maintaining both the original frames/samples and their related metadata. It is a process as old as digital video itself, and one that can be extremely helpful when dealing with hundreds or thousands of hours of digital video evidence for a case.

Reduce file size, reduce duration and maintain the original frames & quality. Bonus, the process is even faster than traditional editing, as you don't have to wait for the video to be re-encoded!

Spatial vs. Temporal Compression

Spatial (Intraframe) compression is applied to each video frame independently, treating each frame as a stand-alone image. This is the type of compression leveraged by high-end video production facilities as it provides superior picture quality and efficiencies in the editing process. Every frame is a key frame.

Consider this: If the DOJ forces Apple to create a new method to access this data in JUST this case, more than one Apple employee will need to be intimately familiar with it. It will need to be well documented, and protected by the very same US Federal Government privacy and security rules and regulations the DOJ is asking Apple to breach (think HIPAA, etc). Cool, Apple can do that, they have been more than helpful putting policies and procedures in place to accommodate government access legally from day one.

Imaging expert Dave Helmly of Adobe will present new applications and discuss next generation possibilities during the "Imaging Supersession" at the upcoming LEVA conference. This LEVA event is the debut forum for CS4!!!!

Here is your chance to learn what is available and what’s on the horizon. You can share ideas in an open forum on imaging procedures and practices.

I was out in Indianapolis briefly yesterday to teach a couple of sessions during the LEVA LEVEL 2: DIGITAL MULTIMEDIA EVIDENCE PROCESSING course, which is wrapping up another great week of DME training for law enforcement professionals today at UIndy. Such a great learning environment with a truly talented instruction and support staff. Many thanks to LEVA, the other instructors, assistants, and yet another great group of students who made me feel right at home.

Congrats to everyone and safe travels home. Have a great weekend!
