I just set up my new ReplayTV 4080 this evening,
and the video quality seems to be quite good.
Definitely better than the older ReplayTV models
and the Tivos that don't use an integrated
satellite decoder. (Those models record the
satellite bitstream directly, so the playback quality is identical to watching the program live.)
I finished the setup at about 7:10 PM local time,
too late to record Futurama, but a friend recorded
it on his ReplayTV 4080, so he's going to send
it to me over the internet. It was a repeat
anyhow, so it's no big deal, but it will be a good
test of the show sharing features.
Since the ReplayTV 4000 series can send the show
to another unit, and it can play from the disk
of another unit, I hope to come up with a way
to send my shows to a Linux server with a very
high-capacity RAID (a bunch of Maxtor 160G drives) for archiving, then play back from that.
Rumor has it that standard protocols are used; if true, it shouldn't be too hard to set it up.
Anyhow, I put a spare PC on a hub with the ReplayTV so that they were on the same port of my Ethernet switch, and have tcpdump logging all
the ReplayTV's network traffic to a file for
analysis.
I hope ReplayTV will develop a model with integrated satellite decoder. That would improve both the picture quality and the channel change latency. Actually, since they already have an Ethernet port, they could just build a satellite reciever with an Ethernet port, sell it as an accessory, and update the ReplayTV 4000 software to record from that.
And ofcourse it moves the polution to somewhere else.
It moves it to a centralized place where it is
easier to install equipment to scrub the exhaust,
resulting in lower total polutants emitted per end-user energy consumed.
No, because to produce large quantities of hydrogen,
you still need a lot of energy. Right now the only
cost-effective energy sources for that are fossil
fuels, nuclear, and hydroelectric, and in the US
we don't seem to be building more nuclear power
plants. Not much new hydro either, AFAIK.
What fuel cells do for you is provide a better
way to store energy. The energy
still has to come from somewhere.
so there was a mini-flame in the large tube that was burning oxygen.
No. By definition, what was happening was that the
hydrogen was undergoing combustion (i.e., burning).
Naturally if the oxygen supply is limited, the
hydrogen can only burn at a slow rate, and where
the oxygen is physically present.
1) How will you automate separating the tracks? If you are recording from spdif it's all going to be one long mp3. I'm sure you could write a filter to do silence detection, but that doesn't work even close to 100%, many song have pauses in them.
If your SPDIF input hardware on the computer lets
you access the User bit, that contains
the Q subcode from the CD, which has the track
number and time information with a granularity
of 1/75 second. One user bit is transmitted
per SPDIF subframe, and the CD Q subcode bits
are packed into those in a pseudo-async fashion,
where 16 consecutive zero bits indicates the start of a Q subcode frame, and a one bit is used as a leadin for each set of seven subcode bits.
Most SPDIF receiver chips (e.g., those from
Crystal Semiconductor) provide a way for a
processor to examine the Channel and User bits.
I have no idea whether common PC sound cards have
this capability. Wiring up an ISA card with a Crystal Semi receiver chip would be pretty easy.
For details, I recommend
The Art of Digital Audio
by John Watkinson. 2nd edition had detailed coverage of CD subcode in section 12.18 and of SPDIF User bits in section 7.11. These may have moved in the third edition, but I expect that
they're still present.
Principles of Digital Audio
by Ken Pohlman. Chapter 9 has good coverage of CD subcode. Chapter 10 includes information on the SPDIF User bits for CD sources, but not in as much detail as in Watkinson's book.
IEC standard 60908. The definitive reference on the CD-Audio format, including the subcode. Not available free, but it's not too expensive (CHF 228.00, about US $133), and you can buy a PDF file online.
How can the creditors possibly believe that the network
will be more valuable to potential buyers
AFTER they get it turned off,
and lose all of the customers and goodwill?
Maybe I'm missing something, but this seems like
the same stupidity that Ricochet went through.
And in that case, the creditors ended up having
to accept a lower offer, not
getting more.
I did read your post, and I fully understood what
you were claiming, and it's just plain wrong,
even though some people may say such things.
The current temperature where I am is 287 kelvins.
A claim that the temperature is "287 kelvin" is
grammatically incorrect. The only time such a
construct would be grammatically correct would
be when the temperature is 1 kelvin or less.
Just as it is correct to say that the temperature
is "72 degrees Farenheit", but incorrect to say
that the temperature is "72 degree Farenheit".
Didn't you learn about singular and plural in
grade school?
Have you ever read any peer-reviewed scientific
journals? There are occasional mistakes even
in those, but usually they get it right.
Wrong-o! I held a working prototype in my own
hands months ago. At that time
the plastics weren't final, but the device
definitely worked.
They've been working on this thing for quite a
while. If you'd actually bothered to read
before posting, you'd have seen that they
already have received round B funding.
I had so much fun with the prototype that I've
been eagerly awaiting the product/service launch
so I can buy one.
(And in case anyone is wondering, no, I don't
work for Danger.)
Wasn't Capitalism designed for the distribution of scarce resources?
Did it ever occur to you that one of the most
scarce resources of all is the creativity to
produce works that people want? Just because
the incremental cost of reproduction of a work
is negligible does not mean that the work has
no value, or that it didn't cost anything to
create.
It may be the case that someday all of the
people who create digital works get compensated
through some means other than per-copy payments
(as some do today), but that's going to take
a while.
In the mean time, if MS wants to charge money
for XP, let them. MS has tried hard to keep
you from having any other choices, but thanks
to the combined efforts of thousands of people,
there are some alternatives.
That's fine if you only use
software you "believe in", or software that
is available at no cost. It's not a reasonable
justification for installing MS software on
your computer without paying for it. If you
don't "believe in" MS software, you have no
reason to use it.
Much though I despise Microsoft and their software,
I've paid them for the for the few copies of
their stuff that I have to use. As time has
passed, I've been able to replace more and
more MSware with Free software, and I'm looking
forward to a day when I can be entirely MS-free.
It's getting close.
just my way of chipping away at their corporate empire.
A better way is to simply not use it at all. If you use it without paying, that doesn't hurt them
any worse than if you don't use it at all. In
fact, if you do use it, and create any documents with it, you're helping perpetuate their monopoly even if you don't pay for it.
Also, if you avoid it entirely, rather than
making unathorized copies, you are then
entitled to take the moral high ground.:-)
It's "60 kelvins is 10 kelvins more than 50 kelvins". Just like "60 volts is 10 volts more than 50 volts" or "60 kilometers is 10 kilometers more than 50 kilometers" or "60 automobiles is 10 automobiles more than 50 automobiles".
You wouldn't say "60 automobile is 10 automobiles more than 50 automobile", now would you?
And to be really really picky, it's "below 10 kelvins",
just like you would say "below 10 volts" or
"below 10 grams". It's not capitalized, and when
you're talking about more than one of them it
gains an "s" for the plural form.
I can think of several candidates for the first single-chip microcontroller. The very first one in commercial production was probably the Texas Instruments TMS1000, although I think they may have had an even earlier version (TMS0970, perhaps?). These were four-bit microcontrollers.
The first 8-bit single-chip microcontroller may have been the Intel 8048, introduced in 1976. It had masked ROM; there was also an EPROM version, the 8748, and a ROMless version (for external program memory), the 8035.
Another possibility for the first 8-bit microcontroller may be the Mostek MK3870, which was a single-chip version of the Fairchild F8 processor family.

It was used in the F-14A.
It is lesser known because the designer, Ray Holt, only received clearance to publish information about it in 1998.
Yes. In the high-end category, people buy whole-house control systems, which are insanely expensive and are custom tailored to each installation. One remote control for such a system costs anywhere from $1000 to $5000. Of course, they are VERY fancy remotes, not just small boxes with a bunch of buttons.
Three Molnyia-orbit satellites is NOT enough to avoid urban canyons. It helps, but repeaters are

Having three satellites in non-geosync orbits (if they're really doing that) is NOT enough to solve the "urban canyon" problem. Which is why Sirius, like XM, has requested a license from the FCC to operate ground-based repeaters. Both XM and Sirius have received temporary licenses.
