My $1,700 47" Panasonic also supports 1080i natively, but it still has less than 1920x1080 in actual screen resolution...
Yes, your set does support 1080i natively... and it may have 1600 lines of resolution, but are these normalized ? Here is a post by "edyee" on [Home Theater Spot] describing the resolution issue.
"Panansonic's quoted resolution is 850 lines of horizontal resolution (# of light/dark transitions horizontally that be discerned, not the number of scan lines). And further, if this is quoted as 850 lines of horizontal resolution per picture height, the total number of lines across the 16:9 screen would be 850x1.78 or approx 1500. The question is what is Mitsubishi's quote of 1200 in relation to? Is it the total across the screen or is it also lines per picture height? If it is not lines/pic height, then normalizing Mitsubishi's number gives about 674. And Panasonic has greater horizontal resolution."
Well lets start on the same page. I'm talking about terrestrial broadcasters. CBS in Los Angeles transmits their 1080i signal at the full 1080x1920 resolution. There have not been any indications in the industry journals to the contrary.
I think you might be thinking of DirecTV. They started broadcasting 1080i video, but low-passed to 1080x1280 in order to lower the bandwidth so that they could fit two HD channels into a single transponder.
And I agree with you on the colour and geometry issue. But you have to admit, the really expensive HD sets that are capable of true 1080x1920 and 720p look amazing:)
I agree with you that any video source that is 2k can be considered high definition.
Firstly: Why refer to "CCIR 601/656" when we are talking about HD ? 601 specifies the image format for digital 'standard' (SD) TV signals (NTSC/PAL/SECAM). And 656 describes the serial and parallel interface styles.
Secondly: I was interested in the poster's definition of 'HDTV'. For instance, what compression algorithm was used 10 years ago ? (not MPEG-2 obviously) How were the streams transmitted ? (e.g. DVB/8-VSB as is currently defined).
The $5,000 HDTV sets do not have the a resolution capable of supporting 1960x1080. E.g. the Sony 36" HDTV's only have a 600 horizontal line resolution. Yet they are still capable of "displaying" 1960x1080 as they downsample the video. This has nothing to do with saving bandwidth as broadcasters that transmit HD in 1080i (1960x1080) send all of that data in a 19Mbps stream.
It's only the really, really expensive HDTV sets that have the resolution to support true 1960x1080
Please explain what "HDTV" means to you. 10 years ago, SGI could only have supported high definition ANALOG TV, not the high definition DIGITAL TV as defined today.
HDTV as currently defined uses the MPEG-2 compression algorithm which was not standardized until 1995.
Why do most Americans insist on using 'Legos' as the plural form instead of the accepted 'Lego' ? I see most slashdotters get this one right (perhaps because the majority of the posters are European ?), the article got it wrong.
Do you say one sheep, many sheeps ? (It's sheep)
One cactus, many cactuses (It's cacti)
One mongoose many mongooses? (Actually this is correct. I bet many of you thought the plural form is mongeese)
A) The vaccine is not FDA approved... if you want to be a guinea pig, go right ahead.
B) It is not just a single injection. You require multiple shots for the vaccine to be effective(nine injections over 18 months I believe).
C) There are a whole bunch of nasty side effects.
D) Anthrax is not contagious.
What would happen if 'Car & Driver' got a 16 year old valley girl to road test a Ferrari ? She would think the car was crap because, not knowing how to drive a stick shift, she would never get out of first gear.
Come on.

Europe tried going the HD analog route. In the US it's all digital.
You will be able to buy a really cheap set-top box that will convert the incoming digital transmission into an analogue signal that your old TV is still able to process. So don't get your nickers in a knot.
That radio is marvellous. Half and hour of audio from a couple minutes of winding, it's amazing. You have no idea how much people in the outlying African areas rely on their radios. They don't have TV and probably don't have electricity so they depend on batteries. How would you like spending 20% of your monthly salary on batteries just to keep your radio going ? Batteries are really expensive (in South Africa at least).
You must understand that for Mandela it really is a big thing: he probably only had radio while imprisoned for 20+ years. It may not be the greatest invention of the century to you: but to a people of whom many don't even have toilets it may just be the greatest thing since sliced bread. It's a big step forward for creating devices that do not rely on an expensive power source.

I just recently broke the 15.4" LCD display on my Dell Inspiron notebook. Cost to replace: $1060.
OK. Imagine if Toyota modified the peddle/gear shift/steering wheel layout every model year.
Then imagine that there was no standard for these across car manufacturers.
Hardware designers seem more willing to standardize on a single format (the DVD-R/DVD-RAM/DVD-RW/DVD+RW wars not withstanding) than do programmers.
The problem, I think, is that programmers have the "not invented here" attitude, and are constantly re-inventing the wheel.

Exactly. Who here would be willing to pay >$900 for a copy of Quake III ? No one, that's who.
Cheap software == bugs. Examples being pretty much all commercial software.
Expensive software == a lot less bugs. Examples being, the Space Shuttle.
The software in the shuttle cost upwards of $1000 per line of code written.
English is but one of the 11 languages spoken in South Africa.

You have just described a console.

You'll just need a new, or perhaps upgrade your existing, ATSC receiver/decoder.

Yes, nice set that seeing as it comes with a DirecTV receiver built in too.
Now can anyone tell me why RCA decided not to allow anyone to record DirecTV programming by not including any video outputs ?
I've heard you get an average of $10,000 more a year with an MBA.
And of course it's much easier to move into a management position if you have an MBA.
Otherwise, when a programmer reaches a certain age, he/she gets kicked in the proverbial nuts and sent on their way. (Or so I've read)

And just how many services are controlled by computers in African countries ? I believe pencil and paper are still Y2K compliant.
I agree that airline radar poses a problem, as Y2K testing in Africa will probably only during the week between Christmas and New Year.
