Quite nice!!!

[AiboPet]

WOW!!

Just when you start to take the Internet for granted....you can click a link and see THIS kind of history!

I'm 46...and can't think of anywhere I would have seen something quite this comprehensive about the "end-to-end" process of TV programming.

Makes one NOT want to just let this all slip into nothing but memory.

This was about the coolest thing I seen in quite awhile. LOVE those old "TV trucks" :-)

very very cool! stuff like this makes the internet worth it ...way more than myspace or any of that crap.

[Dude111]

Indeed it does!

I think all of us on this site PREFER OLDER STUFF!!!!

I Prefer CRT television,i prefer VHS and i would love to get a walkman again!! (A good one made in the 80s not this newer trash that was made up until last year)

In my opinion OLDER STUFF IS BETTER... Better quality,etc..........


Im so glad i found these 2 sites of Grumpys! (Audio and Videokarma) and its good to know HE feels like we all do

This really helped me understand also.
Not having color until I was 8 in 1971, black and white always seemed to be enough for me and a set full of tubes is a feast for the eyes as well. This forum is my favorite by far for that reason!
Its unfortunate that the "media world" is not explained this well.

Is this the same video? You can download various versions of it here, too:

Another member mentioned that site as a source of old TV commercials.

[Dude111]

Yes thank you!!!

I watched it in Real Player which played it BETTER THAN YOUTUBE DID (Kept stopping,etc (FLASH CAN BE QUITE CPU INTENSIVE (NOT A GOOD WAY TO STREAM VIDEO)))


Thank you indeed!!!!!!

I use Firefox with the little YouTube download plugin. Keeps me from being PISSED at the caching. Being in videophile frame of mind when clicking on ANYTHING from the Internet....will just end in tears, so not really a good idea to be critical of a YouTube vid. I'm just happy to see anything like this at all really.

I spent part of this afternoon looking at videos of people who MAKE their own tubes!! Without YouTube....I don't even get to see that, probably FOREVER.

I watched "The Secret Life of Machines" episode on "Tellies" after I watched the '39 show.. Yeah, Utooob DOES suck, but its better'n NOTHIN'...And I'd LOVE to hang w/Tim Hunkin for a day or 3...Bet a lot of the rest of us would, too..

"13 thousand times a second". That would imply that this TV system was the 441 interlaced line system, before it was bumped up to 525 lines. 441 times 30Hz = 13230Hz. as it was 30 frames a second, or 60 fields of 441/2 lines a second. In today's parlance, 1939 TV was 441i 60Hz. Also the sound if I recall correctly was to be amplitude modulated. Which would have sounded horrible in an intercarrier receiver.

If you wanted to, you could fake the appearance on an NTSC B&W set of a 441 line TV signal by using a CECB set to letterbox mode, and setting the vertical height to be overscanned enough to lose the top and bottom black areas. And have excessive overscan on the horozontal to make the geometry of the image look right. Use the luma output if your box has S-video available. Letterbox mode reduces the vertical resolution of the video image to something like that of 441 lines interlaced. Actually it's worse than that, it's about 394 lines, but close enough... If you are really crazy, you could build a 1939 style cabinet that houses a B&W CRT NTSV TV set, and make the mask on the CRT much smaller than the CRT, to crop the letterbox black areas top and bottom, and cropping the side areas to make it 4:3 aspect ratio.

The trick with Youtube to minimize or eliminate streaming interruptions, is to start then quickly pause the video. It will buffer all the way to its end on your computer. Then, resume watching it. You can typically see a three-colored stripe below the video. The brightest color is how far you watched, the medium is how far it has buffered into your computer (you want this one to go all the way to the right), and the darkest color is the unwatched and unbuffered area.

YouTube used to work that way but now if you pause the video they pause the buffer also, they only buffer a certain percentage, probably to save bandwidth on videos that you may not watch all the way through anyhow.

At least that's how it's working for me, maybe something is set wrong?

[AiboPet]

Yup Eric....Works exactly that way. YouTube vids only cache a very small time ahead. I do remember like a year ago when you COULD just pause it and watch the grey line still keep going.

Refreshing the page also now just flushes that cache and starts it over.
