It looks like Verizon might have underestimated the amount of iPhone 4 subscribers they would be getting on their service. It has just been reported that Verizon will be preventing users from downloading entire videos at once to help “ease capacity burdens on the network. "They will also be reducing the quality of the videos by eliminating colors and data “not visible to the human eye.”

"For many television viewers and forensic science enthusiasts, shows like CSI and the spin-off television shows CSI: Miami and CSI: New York are fun to watch and, with their various characters and story lines, continue to fascinate viewers of all demographics. Viewers anxiously marvel at the forensic technology, the latest scientific methodology, and the amazing deductive skills of the forensic specialist. Best of all, the whole case is completed in just one hour."

720p (Black), 1080N (Yellow), 1080P (Blue & Yellow)

1080 for sure, that's in the name.  They're all the same thing folks, and I'll be darned if I can find any formal video specification referencing any of them, so they share that too.  Is it all just marketing BS?  No, but surely the confusion has been leveraged by some DCCTV manufacturers, resellers, and the like to their benefit.

We've all been there. Sitting in a dimly lite room watching someone read the text off from their PowerPoint presentation. Responding to email under the table as we listen to the monotone disseration, looking up only during the brief breaks which occur between slides. Glancing around the room just in time to see one of your colleagues bounce their chin off from their chest. How many foreheads need to hit the conference table before we put an end to this senseless mid-day slaughter? I can tell you this, SlideRocket clearly doesn't want to find out.

SlideRocket is a rich internet application (RIA) being developed by a privately owned, venture funded, San Fransisco based company. The application is developed using Adobe Flex and Amazon's Simple Storage Services (S3), and it's sleek, user-friendly interface is entirely Flash based. It's not browser or platform dependent, so regardless of where you or your team may be or whether you're running the local player from a PC, Mac or Linux box, you're all good. While the presentation authoring tools are impressive, there are a plethora of other features and capabilities you won't find in related desktop apps that I personally find even more exciting.

Some more offline comments and testing recently have raised a critical issue; the use of Square Pixel Sampling and Non-Square Sample Formats. Before that though, let's talk about validation testing. When we get to this level of detail especially, it is important to validate our processing, tools, and complete process. Correcting Aspect Ratio is certainly no exception. In fact, I think we would all agree that when this level of detail really matters, you must validate. Lots of great resources out there about that topic.

"VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/2000/XP), licensed under the GNU General Public License (GPL). It lacks the editing power of a general-purpose editor such as Adobe Premiere but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images."
