You are misinterpreting what I said to be an attack on your personal agenda. I never said I favor big oppressive governments. I only suggested that there should be a global network purely for the enlightenment of mankind and the sharing of useful information. No greed, no power struggles, no investors to satisfy, etc.
Hopefully never. There should be a network that remains purely academic forever. Commercialization is evil. Look what it did to Internet1. 95% of all pages have some kind of ad on them, and finding anything useful when you're looking for something obscure is nearly impossible, whereas in about '95 I could find just about any obscure thing I wanted to know.
Extensions are what make OpenGL great. The core API can go unchanged for several years, but with extensions you can still access the latest and greatest features. With DirectX, you'd have to wait for the next release to get a new hardware feature.
The gnuradio package does include an atsc_tx signal modulator, but I don't know what kind of hardware is necessary to actually get the signal in the air. Transmitting is probably just the reverse of receiving, so you're probably looking at a 20MHz ADC, some way to modulate the carrier, then remove it so that only the sidebands remain (an 8VSB signal modulator - did I get that right?), a 50-1000MHz multiple kilowatt amplifier, and an antenna.
I have no idea what any of that would cost, but if I had to make a guess, I'd say that you could have pirate GNU Radio-powered HDTV for not more than a million dollars or so.
It says on the site that they used GIMP's auto color balancing to adjust the snapshots. That will mess up the colors pretty quickly. Someone else posted a link that has some ads in HDTV.ts format (MPEG-2 transport stream), 1280x720. Take a look at those. I've yet to find a media player capable of playing them, though. VLC screws up the sound, Xine plays the video choppy, MPlayer doesn't support transport streams.
You should probably back those tapes up to a modern format as soon as possible; video tape typically only has an archival shelf life of 20 years.
DAS4020/12: $1300 US, 1200 pounds GB

HDTV via GNU Radio
·
· Score: 2, Interesting
I found out by downloading the kernel driver source code that the name of the board is actually Measurement Computing DAS4020/12, and costs $1300. Thanks to the other posters for also mentioning this.
Does anyone know where to find an HDTV tuner card with drivers for Linux? I'd really like to move my whole theater into the digital domain, without installing Windows (which is DEFINITELY not the right tool for the job, so don't give me one of those "use the right tool for the job fool" posts.. Windows is never the right tool for the job, unless the job is to annoy your boss/employees/coworkers and waste all your money).
I've tried various google searches for terms like MC4020, MC4020 data acquisition card, MC4020 data card, etc., and the only results that actually refer to a data acquisition card of some kind are on either the gnu radio page, or the MC4020 Linux kernel driver mailing list archive. I can't find pricing or distributor info anywhere.
If it costs less than $400, though (which is unlikely), I'd pick up an MC4020 instead of a traditional HDTV tuner card.
Of course an article written by researchers and scientists, who are nerds by some definition of the word, is going to claim that they got their sweet revenge against the jocks. Do you think that if the jocks wrote the article, the nerds would be portrayed so well?
Of course, I'm not complaining I can't get a date. Though I did just break up with my girlfriend because she was going out with someone else and wouldn't break up with me...
One of the major reasons there isn't color management and Pantone, etc. color palettes in The Gimp is because many or all of those color processes are patented. Nobody wants to pay for a patent license for every single installation of Gimp out there, and the holders of the patents seem to want to maintain their monopoly on good looking pictures.
It's a similar situation with Hollywood and music/movies. Entry by the little guy is barred by the huge sums of cash being tossed back and forth by the major players. It's pretty hard for a startup indie outfit to survive. Publishing DVD's is even harder, because of all the potential royalties involved.
Jack seems like a really cool idea. Once I finally got it to work though, the sound was distorted. I mean, really really bad. It sounded like it was being quantized to 4-bit precision, but separately for each major frequency band.
Enough to cause the muscles in my arms to rapidly contract. When I was a little kid, somewhere between 8 and 10, just getting into lower level electronics, I didn't know what the voltage was on a phone line, and so I was stripping live phone line wires with my teeth (my parents wouldn't buy me strippers) to run a cable to my modem, and the phone rang. Yow!
If all traffic becomes encrypted (IPsec, or all through ssl/ssh), then it becomes very expensive on the CPU to transfer data while doing another task. Even on a system as fast as my 1GHz Athlon4 laptop sshd takes as much as 50-60% CPU power when transferring large amounts of data, such as video or audio, across a 100mbit network (scp is a lot easier than smbclient or ftp). Only on my XP1800+ and faster machines do I not notice this as much.
An accelerated encryption unit, with no access to the private keys possible, would not onl speed up my ssh sessions, it would also eliminate the possibility of having my identity stolen along with my hard drive. By not storing the keys in an accessble location, nothing short of an extremely fine grain analysis of the chip itself will get them out.
Yes, it's possible that TCPA could also be implemented to facilitate secure communication between media provider and media system, without potential for user tampering to intercept the data. However, the TCPA system doesn't already support that. That would be implemented on another layer, by Microsoft in the case of Palladium. TCPA is pretty cool. Like someone else said, it's more like having integrated video that you never use, than having DRM forced down your throat at the hardware level. It could greatly enhance security of web servers as well, which in turns benefits consumers because they can rest a little easier knowing that their data is not as likely to be stolen.
I've seen you posting a lot on this thread; it seems you have strong feelings about DRM. As someone who makes videos, music, and software for a hobby, DRM really scares me, as it has the potential to prevent me from sharing what I do with others, if not forcefully at least by creating a de facto standard, convincing users that if it's not signed, it's evil. But, TCPA, just like P2P, has non-nefarious uses as well.
I also have the G90f, which I bought about a month ago. How would you say its color response is? When I first bought mine, I noticed that solid color backgrounds were slightly mottled, there was like a 1%-2% variation in the color in splotches across the image. Did you notice anything similar with yours? Fortunately mine is no longer doing this. Either that, or my eyes have degraded to compensate for the flickering of the DLP projector I just bought...
13" TV? Wow. How do you live with that? My TV is 110". With a 500:1 contrast ratio. With XGA resolution. I bet it didn't cost more than twice the cost of your 13" lcd either (if it really is an lcd. I suspect you may have transposed lcd/crt, since you said your laptop has a crt).
That's because Sony developed the SACD format to "compete" with DVD Audio. The only reason I think Philips is also involved, is because Philips is the owner of the original CDDA license/trademark, and without Philips approval, companies can't use the CDDA logo.
There's a relatively new contribution to the Linux NLE field, called Kdenlive. I haven't tried it myself, but the screenshots look pretty good, a lot like Adobe Premiere (which I use quite a bit).
http://freshmeat.net/redir/kdenlive/36293/url_ho me page/kdenlive.html
And for those of you saying Cinelerra is too hard, I have to agree. It's too slow too. I had to remux my DV files into Quicktime wrappers to load them, and then it took me a really long time to figure out how the timeline works (it's not even close to Premiere), and then playing the video was choppy, on my Athlon XP 1800+ with half a gig of RAM. It's a cool idea, but it really needs a new UI. It's not as revolutionary over Broadcast2k as they said it would be.
The timeline works kind of like Acid's tracks. Each track is a single file, instead of each track being a video layer that can contain any number of events from any number of files. Right now I think that Cinelerra would be capable of producing a half way decent wedding slideshow, but not a whole lot more, at least not without a dedicated rendering farm and months to learn the ins and outs of the UI.
They have their own, security-controlled repository at http://software.lindows.com/ (the repository appears empty until a properly authenticated Click-N-Run request is received, at which point the server gives only the files needed for that install).
If you're going to bash someone, at least get the facts straight. CNR version 0.90 might've used Debian's servers, but that was an alpha test version. Version 3.0 is very very very different.
Lindows really doesn't care if it alienates the Linux community. The attitude is one of "okay, thanks for the thousands of hours of work developing the backbone of the system guys, we'll take it from here, now get lost." The only times Lindows expresses interest in the welfare of the whole community are those times when it will benefit Lindows at least as much as it benefits anyone else. Michael Robertson, while a very charismatic and engaging speaker, is a smooth talking freeloader. Open Source vs. Microsoft, just like MP3 vs. RIAA, is just another easy ride to glory and riches. A while after Lindows becomes profitable, I bet Michael Robertson would sell it to the highest bidder (probably AOL). The really scary thing about Lindows is, Michael Robertson might have as much as $300 million dollars in cash and stock from the MP3.com buyout. Lindows believes that they will win because they've got the dough, and because the marketing+sales department is probably as big as the engineering department. I'm afraid that, because of this, the general public might begin to think LinuxLindowsAOL, just like they currently think PC"Pentinum"Microsoft.
Now that I've really ripped on Lindows.com, I really have to say that LindowsOS itself is pretty darn easy to use. Click-N-Run is great for installing software. The OS installation really takes less than 10 minutes on my Duron 850 and my XP1800+. But, that far from makes up for the careless treatment of the community.

Does anybody know if atsc_rx can be run realtime?
Just what could your 1970's vcr do?
You could maybe try reading the freetype site.

Well now, FAT32 is not an encrypted filesystem, now is it? If it's intended for data exchange, you wouldn't encrypt it.
