Nah. An atsc stream is already digital. Storing it takes very little horsepower, although it does take a "fast" hard drive-- the stream is 19.39 Mbs. Decompression could be a problem, but semimodern video cards have partial MPEG-2 decoding hardware built in, which substantially lightens the load. IIRC, wintel PCs only need a 800 MHz PIII to decode, assuming that video card acceleration is available.
Apple hasn't exposed the necessary APIs, but if they wanted too, they could. But personally, I wouldn't expect any movement in this area until CoreVideo and CoreImage are finished.

ATI and nVidia's innovations tend to trickle down into the next generation of budget cards. High end audio gear is often produced by companies who have no intention of selling to the low end. So while the punter who's shelling out for a dual 6800 Ultra setup may be funding the next generation of cards you might actually be able to afford, the punter who's getting the Wilson Audio speakers custom finished to match his ferrari is not doing much to improve the quality of low end speakers.
Much of the crazier audiophile stuff is sold either to vinyl fans (who actually might "need" an isolation table) or to people with more money with sense. If one wants to further reduce the noise floor, but one also lacks a degree in Electrical engineering, ones wallet is ripe for the picking.

Interesting. It seems that my graduate school had access to most of the complete works of these right wingers. Not surprising, really-- there is a center for the study of right wing political economy on campus.
Oh, I chose the most general subject headings, mostly for speed-- none of those figures encompasses the totality of works on the subject.
Oh. My current setup involves the use of a smaller CRT hooked up to the VGA output of a set-top box. It's only 720p, but technically, 720p is still High Definition.
I figure that if I need a bigger screen, I'll move to a projector-- sometime, way off in the distant future.
You have a SDTV? Isn't that kind of a waste? Sure, it's nice to be able to watch the subchannels on one's PBS feed, (avoiding Tucker Carlson, and the more marginal programs) but most channels don't use them for anything more than weather graphics... I suppose the picture's marginally nicer than a ntsc feed.
The DVHS machines are notweorthy because they can record and playback streams over IEEE1394. A number of companies also produce prerecorded content on DVHS tape-- but of course, there are onerous DRM restrictions. (HDCP, anyone?)
Virtual DVHS simply emulates a HDTV recorder, and it produces a.m2t stream, which can be either played with VLC, or sent back to the tuner for hardware accelerated playback.
IEEE1394 does include a encryption option, though, and it is not completely clear whether the presence of the broadcast flag will tell a set top box to use this encryption. A consumer model recorder may have the proper codes, but I am not so sure that a computer will be able to handshake with a atsc tuner.
A certain Korean electronics giant has produced a whole range of HDTV tuners, some with interesting features, such as RGB and IEEE1394 interfaces. They claim, however, that the products produced before November 2002 require a firmware update.
If you fail to upgrade your set top box and the Broadcast Flag is broadcast, your set top box could lock and display nothing until you perform the upgrade.
Now, although they claim
The Broadcast Flag will not prevent you from making copies of your favorite TV broadcasts.
So what is the broadcast flag for? If a certain owner wishes to use a VirtualDVHS program, instead of a rather expensive DVHS deck, what guarantee do the content mafia have that those streams won't be passed around like candy?
I feel as though the consumer electronics people have somehow been encourage to lie, cheat, and cajole their customers into compliance...
Testing distributed primality algorithms. I should have thought this was obvious.
And, no, one does not encrypt with Mersenne primes. The rarity of such numbers makes a "brute force" crypto-analysis seem rather plausible. Best to use an ordinary prime number-- there are, after all, many more of them to choose from.
The "G4" or PPC 7xxx chips are made by "Freescale Semiconductor". IBM makes the "G3" (PPC 7x0) (which isn't used by Apple anymore), the "G5" (PPC 9x0), and the POWERx chips.
But how much exatcly does it take to send a proper HDTV signal?
An ATSC channel is is 19.8 Mb/s, which can be divided into several subchannels. Most of my local broadcasters divide their allocations up into a HDTV channel, and a SDTV auxiliary channel. Usually the the subchannel is used for weather information, though my PBS channel gets into the habit of showing "Ooh what a pretty picture" stuff on its main channel, and regular PBS programming on the subchannel. PAX shows 6 channels of SDTV-- mostly religious crap, I would imagine.
NeXT is an attempt to render a logo in ASCII. Most of us are stuck with dreary typefaces that don't include a full height 'e', so it looks rather odd. The 'e' supposedly stands for a variety of words: "education", "exponent"...
The logo was designed by Paul Rand, who designed logos for UPS, IBM, and British Petroleum, among others.
The persistent use inter-capitalization (NextCube, OpenStep, AppKit) probably derives from too much exposure to the NextStep api and Objective C-- both of which use inter-capitalization to enhance the readability of code.
Pity they don't list the CPU's model number. I think it's a 7447a, which freescale lists as having a maximum clock of 1420 MHz. Perhaps Apple has a separate, exclusive supply line. From the looks of things, the 7447a can't really take advantage of DDR memory, either.
Freescale does produce a Dual Core G4, but those chips also have 1MB of L2-- a feature that Apple would be sure to trumpet. They're 32 bit, though, so Apple is unlikely to use them in a "Powerbook G5"
Not sure if my kitchen is clean enough to host a computer. I mean, consider making spaghetti sauce. You have a boiling hot pot of tomato puree, meat, onions, etc., simmering on the stove for a couple of hours. Occasionally, the mixture gets a bit hot, and small droplets are apt to go flying about, possibly landing on delicate electronics.
In addition, my kitchen is so small that anybody attempting to use the "kitchen computer" is likely to get warned off by a territorial chef.

TOSLink can be easily integrated into a 1/8" stereo mini jack. Apple just needs to consult whoever designed the Airport Express for a demonstration.

Interesting. You might have shown slashdot the true breadth of your knowledge by explaining how you came to your essential conclusion:
"People who buy CRTs with the aim of displaying more than 786432 pixels are wasting their money."
Instead, you have regressed to the level of a twelve year old. I sometimes have that effect on people. Annoying, really.
So, all of those people spending hundreds of dollars on 21"--24" inch monitors are wasting their money. Interesting
petit bourgeois scum...
As long as the (4:3) monitor is capable of at least 1280x768, it will display 720p hdtv, within a letterbox.
Well it just has! How about my nice SDTV :-)

So, 17-18 Mb/s should suffice.
NTSC specifies 525 lines, 480 of which are visible. But that's 20th century tech. The best modern television sets support 1080x1920.
It was introduced with System 7.0--May 1991
The logo was designed by Paul Rand, who designed logos for UPS, IBM, and British Petroleum, among others.
The persistent use inter-capitalization (NextCube, OpenStep, AppKit) probably derives from too much exposure to the NextStep api and Objective C-- both of which use inter-capitalization to enhance the readability of code.
e.g the class NSBezierPath implements the method
The "NS" namespace comes from OpenStep-- the original Nextstep used the "NX" prefix. NS stands for Next/Sun.
