I do not get it, that system SUCKS.

One remark: Use a good antenna. I have one in the attic. Oh, maybe I need to turn my antenne, there was something about going vertical polarisation.

Wow, and I have it horizontal still :-) Still I get a hundred stations :-) Maybe in the weekend I will turn the antenne.
Joerg, protest with your senator, ask for the European system ;-). LOL
Most of that has to do with the tuner. Some brands cut out the picture completely with drop outs in the data stream. Others show the anomalous picture segments, and only drop out bad sound segments.
You don't have mountains like we do. The highest point in NL is 322 meters (I lived on the slope of that one), out here it's over 2000 meters. Watch a Bonanza re-run and you can see the very mountains that cause multi-path out here.
Nah. But I could imagine others will. In the US most everything has to be sold via a brand-new "must have" feature. You can't just go out and tell people they have to buy a new TV so that additioanl tax renevue can be generated by auctioning off some of the UHF band. You have to come up with a compelling reason and that reason is HDTV.
Yep. Yesterday I could see a documentary where they had even given the street lamps a spit shine. Then "Ah, you guys forgot that one back there!" What I noticed is that they squish more make-up on the newscaster's faces. The difference is striking when they interview someone out of the blue where there is no time for make-up. Then you can see all the wrinkles and pimples. And guess what? IMHO David Letterman looks a bit older in HD than he used to on our old set. But I don't watch those shows so I have no idea how old he really is.
I've seen that. Interpolation sets in. Then some more interpolation. Then parts of the image kind of freeze up, later the whole image becomes still. Switched back to the analog channel with same programming and saw extreme ghosting and snow but still intelligible.
-bw N DVB-T bandwidth (Mhz) - N=6, 7 or 8 (default)
-tm N DVB-T transmission mode - N=2 (default) or 8
-hy N DVB-T hierarchy - N=1, 2, 4, NONE (default) or AUTO
-b beep with frequency depending on signal to noise ratio (disk align)
-analyse Perform a simple analysis of the bitrates of the PIDs in the transport stream
NOTE: Use pid1=8192 to broadcast whole TS stream from a budget card
The -b option was my contribution :-)
dvbstream works both for satelite and for terrestial, and can also stream the content over the internet via multicast.
I use dvbstream only for terrestial, for satellite I use xdipo, it creates a log file and writes to it anytime a bit error occurs, with timestamp. This is useful if you later need to edit it and re-align audio-video sync, something that goes often wrong when editing a transport stream or mpeg2 stream with missing packets. ftp://panteltje.com/pub/xdipo2.jpg I wrote xdipo, soem related programs too. Most everything is scripted, xdipo has timers too.
So you watch TV via a PC? That would not fly in our living room. I am married :-)
But it's always good to make sure new TV sets are PC compatible so if this while DTV stuff falls off the cliff because of multipath or whatever people could view via the web some day.

Neat! I never saw someone put that much effort into TV reception.

In my view, now things are still moving, it is best to consider the 'TV" in the living room more a 'monitor'.
That may sound cryptic perhaps, but if the 'TV" (monitor) has a DVI or HDMI connector, then why not let the PC do the decoding, processing, recording, etc... (after all most people will use timeshifted playback I think), and simply update the soft if 'Yet An Other Standard' is agreed on. There is an other issue too. I am way into the sixties, and these days need glasses to see really sharp close by (far away no problem). If I sit in a living room, at say 2.5 to 3 meters from a set, it is too far for glasses, and too close for no glasses. What also counts is the viewing angle:
160 inch at 4 meters sharp without glasses
80 inch at 2 meters.
----------------------------------------- unsharp with or without glasses
40 inch at 1 meter ------------------------------- sharp with glasses
20 inch at 50 cm sharp with glasses ------------
So the question then becomes: What is you 'HDTV' perception? Test it yourself, can you see the individual pixel at your living room viewing distance?
1) yes
2) no
if 1 you are fine. if 2 you are not REALLY watching HD.
This is the stuff they will not tell you in a TV shop.

However this one is only 320x240..... A HD one would work perhaps...
Special TV glasses would work too. But note the viewing angle, to get the same at 50 cm from a 20 inch monitor, you need a 80 inch screen at 2 meters.
My living room is not that big, and I cannot afford a 80 inch screen. Projectors suck, and eat lightbulbs like we eat onions.
Yep. When the one at our church went poof someone said "Here goes another five hundred bucks". But with a congregation of >200 you really don't have a choice.
Our church seats about 300 so it's a pretty large room. The projector hangs from a ceiling pod about half way from the front but AFAIR the bulb didn't cost more than $500. I thought that was already quite outrageous. The display on the projector screen is nice, probably about
Yes, even the new Dell here supposedly can do it. Still have to find out why they didn't send the Y-cable with it that has VGA coming off one end and HD off the other.
Video game are something I'll probably never touch during my time on earth. When I was a kid I built a pong game, from DTL chips pried out of discarded mainframe boards (with my pa's blow torch). Just for the challenge, the millisecond it worked I gave it away.
Makes sense for the serious user but not for us. Since you seem to know a lot about DTV, is there any comprehensive guide that shows what will play on the digital OTA channels? Like those weekly guides that used to be available at the supermarket? Our local paper gives one out each weekend but the digital channels aren't in there.
I found much the same thing recently but the viewing in the store doesn't tell all. Like listening to stereo equipment in a showroom, the store can change the environment and setup to sell any unit. The VFW where I used to hang out bought a 32" Visio and I wasn't impressed with its real life performance, though it looked "decent" in the store. I ended up with the $1300 variety (42" Panasonic 1080p plasma).
No, they picked 8VSB (for over the air, and a different modulation for cable) because at that time COFDM wasn't developed enough. The US standard was defined before the European one. This stuff has been waiting around for ages, (15 years?), and not really going anywhere.
They made it very complex with something like 13 different screen size and frame rate combinations and the requirement to deal with incoming 1080i with reformatting for smaller displays for decoders. That's made the decoders too expensive and made them wait for "Moore's Law" to catch up. Add that it's not a worldwide market so the volume is lower.
They took so long that there's no US receiver industry left to protect. And Direct Broadcast Satellite and Cable and the Internet has left the decentralized broadcast industry with a declining market.

A PS3 is far more than a video game. It incorporates one of the most modern CPUs to date, and Sony allows the user to add their own Linux OS to use it as a computing platform.
It is a good deal. One gets a BluRay disc player, a game console, and a PC all in one package!
