I'd support this except for a few key issues (you clearly haven't thought this out):
1) Reds in NTSC are either illegal (out of gamut) or very close to black (bad for black and white sets)
2) solid color borders and constant flashing cause bandwidth issues to crop up, making the content illegible
3) Part of the issue with delaying the shut-off is that MANY full-power TV transmitters are on their last legs and new parts are unavailable.
4) You don't need the "If you did not expect this, " part.
5) You are stupid.

Actually, Digital has a wider reach with the same power output which is why most stations have had power greatly reduced from their analog to their digital transmitters. Unfortunately, DTV is very susceptible to multipath (you see this as "ghosting" in analog, with a low-grade digital receiver, you see this as "no signal") and in many places, with the lower power required for interference prevention with neighbors, the coverage becomes reduced.

You won't be getting HDTV with one of these converter boxes, but you'll be getting the SD sub-channel, which has the advantage over analog of zero static.

Actually, you can get the HDTV channel, your box will just downconvert it.

There is nowhere that anyone who watches analog TV can claim that.

Actually, the transmitter site is quite a place, and you can get static-free reception quite a ways away from one too.

Over the air digital broadcasts, which is what these converter boxes are for, are actually the only way to get a full-bandwidth signal currently.

Define full-bandwidth. MPEG-2 is compressed, OTA or otherwise.

(All of the cable and satellite companies molest the signal in various ways to maximize bandwidth.)

They recompress it for their digital service tiers because they cannot easily simply retransmit the inputted MPEG stream. While it is possible, it becomes an issue of signal management and converting to baseband and recompressing is easier than playing with MPEG streams.

And there's absolutely no DRM on OTA digital broadcasts.

Most ATSC encoders and Muxers offer a variety of encoding and encryption options. Broadcasters could broadcast signals that are not watchable or listenable by viewers, but they would be blocking almost all viewers (broadcast equipment with the proper keys could still decode it).

They're not "rolling out" digital. It's already here. All this program is supposed to do is help people who haven't already upgraded, even though they've had about ten years to do so already.

Not all markets have had digital stations for this long. North America is quite unique in the high number of individual broadcast areas (we call them markets) and the nations of this continent have had logistical nightmares trying to arrange frequencies.

They make wonderful little boxes that you can plug a real HDD in and plug a memory card in and it will transfer the data from the card to the HDD... or you can just use your computer when you return home. I personally just use one card per device and when the portions it writes get full, that data gets archived and wiped from the card.

Education

+ - Runnig linux with the same username at schools 2

Submitted by
Carlbunn
Carlbunn writes "I'm part of a project that's installing Fedora on Brazil's public schools, in the state of Santa Catarina. One of the requisites of the project, is that a whole class of students logs with the same account on the machines, and gets permission to write in the class own folder, stored on a server. The server also has a LDAP server. The thing is, when multiple students open some programs, like firefox, only one copy may run, and we receive a message that's already open in the other machines. We did fixed the problem making home folders and links to every user, but the result got to be very messy, and it doesn't allow simple creation of new users (each class is one user). Is there a more elegant solution? I want to ditch the LDAP server, but to do this, I have to present a better solution to the bigwigs. Centralised remote support is also a big plus. Any ideas?"

As a SysAdmin that handles multiple computers and windows versions, the IE7 update is being skipped since it broke internal apps at my company.

After checking sever machines, both 2003 and XP, IE7 is not listed as an update or a hidden update. A critical update disappears, What gives?"
Input Devices

+ - Can the Trackbar Emotion Replace the Mouse?

Submitted by
ThinSkin
ThinSkin writes "The Trackbar Emotion is an ergonomic input device in which users can move a horizontal bar from side to side, and rolled up and down, to move the cursor. Because it sits below the keyboard and keeps your hands close to the main typing area, there's no need to reach for a mouse — helping to reduce shoulder strain in the process. Aside from that, moving the trackbar is a bit different from moving a mouse, which for some people might help alleviate symptoms related to RSI or other disorders. This is very much similar to the RollerMousePro featured a couple of years ago, although according to this review, the RollerMousePro is clearly a more superior product."

What they did not provide Vista with was the ability to tell which sounds are coming from the speakers and which sounds are coming from your mouth into the microphone. The result? If you play a sound file with Vista commands in it, Vista does what the sounds tell it to do. Even if the commands are to delete all your files and empty the trash to make sure you can't get them back!


This means that sound played through the speakers from any source could trigger voice command actions. User-friendly? You bet. Safe? Well ..."
