The antenna array is a beautiful piece of marketing by Aereo. Who could object to renting an antenna?
And, in fact, if the output of that antenna -- that is, the radio-frequency signal -- was transmitted to the home (as CableVision was doing back in the day) I think that Aereo would have an slam dunk. But that's not what they are doing.
They are converting the microwatt signal coming out of these antennas a few times. First, they are separating out just the channel that the user wants to watch, then they are digitizing that signal and encoding it onto the internet. That's what I don't think they are allowed to do, and that's why I believe they'll be shut down.
For still photography, focus isn't a terribly hard problem to solve. Autofocus works, and DSLRs let you compose, focus, and shoot manually as well. Easy peasy.
On the other hand, for movies shot using large-format sensors, focus is a huge issue. The amount of work spent following focus on a movie is significant, and it fails more often than you might think. Modern lenses are incredibly sharp, but they have such a tiny range that is in perfect focus that they are hard to use. Admittedly, the people who use these cameras and lenses are professionals with years or decades of experience, and they do well...
I recognize that the amount of processing that goes on to make these images makes a motion picture camera a challenge, and the number of high-end motion picture cameras is probably a tenth of a percent of the DSLRs that are made, at most. Still, we could just capture the 40 MRays and do the processing later; storage and networks are getting faster and larger all the time.

At the time, one of the most popular magazines was "Reader's Digest", which edited long articles into short three-page summaries. They did a pretty good job of it. They would often have a "condensed book" as well.
After reading the Reader's Digest versions of articles, though, it was difficult to go back to long-form reading. There's really nothing new here!
I havent been here for years!

It would be cool if we could track the trackers, and post their location on maps in real time; showing where they troll for cars, where they park at night, what donut stores they frequent. After all, the license plate trackers are plainly visible, anybody could see them and remember where and and when they did.
....find another client.
The real value here is it enables much more granular logging.
I object to this article, however, on grounds that this is not news. It's a press release, and crap like this is why I only visit slashdot every few months any more.
Yes. I understand that they have built these arrays of so-called microantennas. I believe that they are props, fakes, shiny objects to distract from what is really happening.
Those antennae are tiny, too small to pick up the relatively long wavelengths of current transmissions. The are packed together so tightly that they would be shielding one another from the signals. Running analog signals from those antennae to tens of thousands of separate tuners? Come on, really?

Does anybody really think that there is actually one antenna per customer? And that that antenna is hooked up to a particular DVR? And that that antenna and DVR are connected to just one customer?
I just can't and don't believe it. The 'antenna array' is surely a prop, and the DVR has to be a rack of shared servers.
I did visual effects for the first four Fast and Furious movies. We did a lot of the car photography on a green-screen stage, and comped in backgrounds shot driving down streets. We used arrays of film cameras, usually Arri 435s (on Fast 2 we also used VistaVision cameras.)
These would be much simpler, cheaper, and more rugged.
There are similar cameras from Point Grey [ptgrey.com]. These have been out for quite some time. The Point Grey cameras are an order of magnitude more expensive than these vaporware cameras, though.

Curiously, in my youth in the 60's, we referred to Luna-9 as a "hard landing", and the first "soft landing" was Surveyor 1 three months later. Now, it's clear that the Luna 9 lander really was a soft landing (similar to the landings of the Mars Pathfinder and Spirit/Opportunity rovers) and we were just ragging on the Soviets.
Sending a neutrino beam through the earth will be faster than taking the great-circle route across the surface of the earth.
Of course, one would have to send a ridiculously large number of neutrinos to be sure to have them detected, but that's just an engineering problem.
I don't think any of the designs will get up to mach 10 in the atmosphere, there's little point. Staging out of the atmosphere is a lot easier. And once you're in space, it's probably easier to kick yourself along (a boosted skip-glide) around the world to get back to the launch point.
With fiber optics...I don't think it's very easy. Especially with the new doped fibers that do their own recharging.
It used to be that there had to be transceivers every so often along the fiber, to turn the optical signals back into electronic signals, then generate new laser pulses. The new cables basically build lasers into the fiber, allow it to refresh the signal without going through that process.
