So, given a typical PC, how much would it actually cost to equip it such 
that you can record and play back TV with it? What actual hardware and

[No, I have no intension of doing this. I'm just curios.]

A capture card is needed, and I'd recommend a sufficient amount of 
memory, disk space, and a decent video card for playback.

Over here, capture cards vary in price; Hauppage is a popular brand from 
what I've read/seen.  There are some limitations, though - some won't do 
digital channels, most won't do scrambled channels, etc.  Pricing is 
going to vary from a few hundred bucks to a few thousand (depending on 
what other upgrades you need).

You could get a Slingbox, it'll broadcast your TV stuff over
internet so you can access it anywhere with a good connection,
you can use it to control a DVR, your cable box etc.
They're a couple hundred bucks or so...

For Windows, a couple hundred bucks for the capture card and "Windows 
Media Center" (aka MCE), or a more recent version of Windows. That's 
pretty much what Media Center does, along with showing pictures and 
music and stuff like that. It also talks to Xboxes and "media extenders" 
so you can network it thru your house like AppleTV does.

http://en.wikipedia.org/wiki/Windows_Media_Center

There's also MythTV if you want to do it with Linux, don't mind the 
typical expert-tolerant Linux type interfaces, and don't mind stealing 
the TV listings. (Or have they fixed that lately?)

Most capture cards come with some form of primitive Windows software for 
doing this.

I understand TiVo runs some form of Linux inside.

Many places sell machines in a stereo form-factor (i.e., a low flat 
case) so you can put it in your stereo rack.

Indeed yes. And they all seem to be very expensive. I was wondering 
whether the technology that goes into them is actually expensive itself, 
or whether you're just paying to have something that works out of the box...

  I honestly can't believe you are such a computer nerd, yet so clueless
about basic PC hardware.

  The only thing you need is a graphics card which supports video out,
and then you connect it to a TV (or VCR) which supports video in. I have
owned such a graphics card myself at one point.

Hey, nobody knows everything. ;-)

I know about processors and RAM and stuff, but exotic things like fancy 
video processing or infrared communication are outside my experience.

I know my laptop has S-Video out on it. (While not really knowing what 
S-Video is.) I was really astonished when I hooked my laptop up to the 
TV; all the text was unreadably blurry. But then, I guess you normally 
view a TV from the other side of the room, so why bother making it 
produce a crisp image of something you can only see from a few feet away?

I was just wondering what it takes to connect a normal PC to a TV. It's 
not something I've ever tried to do, or wanted to do, but I figured 
somebody here would surely know the answer.

I know 20 years ago it required an expensive scanrate conversion box. I 
haven't really looked at it since then.

(My dad claims his TV has a VGA input socket. But then, I suppose it is 
an LCD, so multiple scanrates probably isn't an issue...)

  Well, that's the problem with TVs (and PAL/NTSC). There's little that
can be done about it (although the quality if the video out chip in the
graphics card can help some).

> I was just wondering what it takes to connect a normal PC to a TV.

  A device which converts VGA to video signal.

Depends on your videocard.  My laptop has an S=Video out, so usually I 
just have to plug it in.

I have to disagree with Warp - I don't believe this is not an NTSC vs. 
PAL issue; NTSC and PAL signaling are different enough that the image 
would appear corrupted (different number of lines, different scanrate, 
etc) and would flicker a lot (PAL is 25 fps, NTSC is 29.97 fps).

That said, you should have settings in the video drivers to select the 
output format, or there should be a utility to switch it.

A friend of mine was having fun trying to do that with his laptop, no  

picture. Faffing with the video drivers, no picture. Turned out he neede
d  

to invoke the secret Fn+Fx key combination to switch screens. After some
  

pointers I think he ended up with a dual monitor setup so he could set t

resolution of the TV independently from his laptop screen.

Yeah, often times there is a key combination to get it turned on.

Not hard. With modern TVs aand computers all you probably need is a cable.

I've got one in the cupboard that plugs into a standard VGA socket and then
into a TV's video in. Can't remember where I got it from.

Not in the US at least. Look up "tv capture card". I got a full-blown 
system, 300G drive, 1G ram, dual core 3GHz machine with dual tuner card 
and hardware mpeg, fairly high-end video card (Radeon whatever) 7.1 
surround sound yadda yadda for just under $1000.

The tuner cards themselves are anywhere from $50 to $150 depending on 
how many channels they can tune at once, whether they have hardware mpeg 
support, etc.

If you're commenting on the horizontal boxes, they're a bit more 
expensive than a tower, but the tech inside is identical, including the 
motherboards and all that. It's just rearranged inside to fit.

That's what you need to hook it up. Or "composite", which is a yellow 
RCA plug. (S-Video carries the color and luminescense on different 
lines, or something like that. Somewhat better, but not a lot.)

That's the TV. If you shop around for a TV that's clear, you can read 
80x24 on it pretty easily.

  I didn't mean to say it's an NTSC vs PAL issue, but that the NTSC/PAL

One of the more popular systems for Windows is BeyondTV. You also get 
the ability to tell their system, "Record all new episodes of X", and it 
will automatically schedule them. I **do** suggest that, no matter what 
you use, you set it up on its own dedicated PC. While ones recorded on 
mine, and its not that bad of a system, are mostly watchable, if I am 
doing anything that requires disk access or CPU use, it can fowl up the 
recording, making it play back poorly (or having it not play back 
watchable at all). I have no idea how well Media Center works for doing 
this, but you ***won't*** find it listed as a good alternative on *any* 
site dedicated to TV capture cards. Take from that what ever you want.

Don't get ATI though. The software a) didn't work when installed (not 
compatible with the motherboard), b) let you watch, when the update 
**finally** became available to patch it, but then wouldn't record and 
c) their TV program scheduler is handled by a third party, which hasn't 
released an updated version since like 90 versions ago of ATIs media 
center software, so it won't show the mini-view of the channel, its not 
integrated very well, and it will "look like" its set up to record, but 
it won't, since a different bug prevents that. Mind you, this is on 
"my" system. Some people get it to work... Fact is though, unless AMD 
has redone it, now that they have ATI, their software is garbage.

Media Center does something like that. (I.e., it might not do the same 
thing, but it does something you could describe the way you just 
described it.)

Yah. Actually, I don't watch that much TV, so I'll often run bittorrent 
there or POV or something. Running something that doesn't blast the CPU 
or disk much, or which hits the CPU but is set to run at a lower 
priority, and it seems to be fine.

I don't have any complaints about mediacenter itself. The hardware I 
bought seems pretty sucky, but the actual mediacenter program itself 
works fine for me. And it's quite easy to use.

If you have a DVI output and a modern TV with HDMI input, then you simply 
buy the correct cable which is about 10 quid.  DVI and HDMI are electrically 
the same, just different connectors (plus HDMI can include digital audio).

Search Amazon.co.uk for "DVB-T".  That will sort you out in the UK at least 
for the hardware.

Nobody I know of has a TV this new. However, my latest video card does 
have DVI output. (Fortunately it comes with a DVI to VGA adaptor, so I 
can still plug it in to my monitor and get a picture...)

Actually, for that matter, my dad can use DVI or VGA with his PC, and 
there doesn't appear to be a significant difference...

Most laptops I've seen have a big icon in the system tray that won't go 
away. When you click it, it gives you a menu that lets you instantly 
change resolution, colour depth, etc., without going through the whole 
settings dialog. Usually switching output is one of the very big, 
unmissable options.

Well actually an LCD only uses 1 or 2 scanrates (usually 50 and/or 60 Hz), 
the difference is that an LCD will include sophisticated DSP functionality 
and a frame-buffer anyway, so scan-rate conversion comes almost for free.

...which is the part I was getting at.

BTW, is it true that an LCD is matrix addressible? (i.e., all the pixels 
can be changed exactly simultaneously.)

You can only change a line at a time.  You charge up all the "column" wires 
to what voltage you want, then power up the row line which opens all the 
transistors inside every sub-pixel on that row, hence they all the get the 
voltage you wanted.  You then turn off that row (and hence the transistors 
close) and the sub-pixels remember their voltages until you come round next 
frame.  You can only do this process one row at a time.

So yes, it's matrix addressable, but no you can't change all the pixels 
exactly at the same time.

I see...

For what it's worth, does "TFT" actually mean something? Or is it just a 
marketing term that means "hey, this screen is great!!!1!1 please buy 
me!!1"?

As Michael said, it is the type of transistor that is laid down onto the 
glass in every sub-pixel.  TFT is also called active matrix (ie each 
sub-pixel is "active" because it has some control circuitry).

FWIW the opposite is passive matrix, which is basically a grid of wires, 
with a layer of LC (and no electronics) between the X and Y grid lines. 
Because LC needs above a certain voltage to work (let's say 5V), you can 
apply +4V to each row in turn, and then a voltage between -1 and -5 V to 
each column to set the brightness of just that row.  If you do the frame 
quick enough you can make a steady image, but then you get problems with 
stray charge "spilling over" from one line to the next because there is no 
time for voltages to settle.

There are numerous other problems with this method which makes it only 
suitable for black and white displays or very low resolution colour displays 
(eg low-end mobile phones).  Any monitor or TV is going to be TFT.

Yeah crazy ain't it.

Except some people do read the instructions, but six months later need to  
do something they've forgotten the function for and then have to locate  
the manual, which by this time had migrated to the back of some drawer or  
been accidently thrown out with some rubbish.

	We must have vastly different notions on what constitutes expensive.

	And proper video card drivers. Take it from a Linux user who's suffered
on this issue.

Oh, I see - I misread - and I agree, I get the same kind of blurriness 
Andy mentioned on my NTSC TV here.

Likely. I've been a professional computer programmer for 30 years. I 
don't mind spending money to get a decent system that fits my needs.

On the other hand, the TV it's plugged into is probably 15 years old at 
this point. I buy quality stuff when I can.

Relatively speaking, you pile up all the hardware together, it's pretty 
inexpensive for the machine it is. If you bought all the parts 
individually and left out the tuner card, it would be more than $1000. 
It's a pretty high-end tuner card, too. (I'm assuming you're saying 
$1000 would be expensive regardless of the machine it buys. The machine 
has a bunch of stuff in it I didn't list.)

A bottom-of-the-line machine from Wal-mart in the same time period was 
some $300 or $400 without any OS/software on it, no DVD drive, etc.

Mine does. But then I noticed it also installed a plain old Video for 
Windows driver, so I can capture just using VirtualDub; the same program 
I use to convert bunches of PNGs (fresh out of POV-Ray) into video 
files. It's a lot better than using the crappy included software.

I honestly can't believe I'm 17 and I would be able to answer these

Wow! Didn't know it could do that. Mind you, the display look crappy, 
with a lot of lines through it, so it doesn't "look" like its going to 
come out too well (even if the result might be OK), but I guess I really 
need to look into what that program actually does...
