Here is a link to the Don Spencer hit version on YouTube. (It was a minor hit in the UK in 1962 or 3). Don sang the closing theme on the TV show. Don is now a children's TV entertainer in Australia.

Enjoy!

Opps! forgot the link.

Thanks!

I didn't realize there were that many versions of the theme and that many verses to the song.

I'm trying to find a link to the version on "Space City Special", as the sax backing and solo really adds a lot and I don't hear it any of the versions I've found using your link.

I think Fireball XL-5 would make a great live-action movie, provided no one who worked on the recent live-action "Thunderbirds" movie has *anything* to do with it!

Or on somebody's checkerboard blouse or tie. The little tiny black-n-white lines are high-frequency information that goes above 5 megahertz on the band. As a result, the black-n-white lines "bleed" into the Chroma part of the signal..... thus creating a rainbow effect. (It is really odd seeing a color rainbow in the middle of a black-n-white film.)

And you're right, S-video would eliminate that effect since the Luma is kept separate, and thus there's no way for teeny-tiny checkerboards to corrupt the Chroma signal. Result: Better picture.

.

I remember when I upgraded my PS2 from Composite to S-video, and YES there was a difference. The picture went from a kind of blur, to where I could see the individual videogame pixels on the screen. In a word:

"Sharper"

S-video was also the output the was used on Commodore 64s back in the 80s. The purpose was to allow people to upgrade from the standard Composite output (which made the color "run" and the on-screen text difficult to read), to a nice, clear S-video picture that was as sharp as a tack.

No there are 486 visible lines.
243 lines per field.
The first (line 1) and last (line 486) are actually half lines.

You might ask yourself how is it that an RF modulated signal running in RG58, RG59 or similar shielded coax will be "more" susceptible to to "interference from local stations and in-home electronics" than the same signal running on the yellow rca cable which is also coaxial, only lower quality shielding, and transmission characteristics. Seems to me it's gotta be as good or better.
The shielded coax is not completely shielded.... it has exposed metal bits that can pick-up interference. In my last hotel, my cable stopped working, and in order to watch TV I actually use my coax cable as a kind of antenna (move it around until I got a signal & then taped it to the ceiling).

RF cable can pick-up external signals (like channels 3 and 4 over-the-air) (or noise from refrigerator motors, the TV set, or elsewhere), thus interfering with whatever you're trying to watch from the DVD, PS2, or ATSC-to-NTSC converter.

As for composite, this is a baseband signal that sits at 0 megahertz. (Versus RF3 or RF4 that sits somewhere around 60 megahertz.) There's very little interference on the baseband. Now I'm not saying composite is perfect... only better:

- If I connect my DVD using the Coax, I get interference lines running through the signal, due to interference from over-the-air stations & other spurious noise.
- If I connect my DVD with Composite/Baseband, I get no interference.
- Clearly Composite is better than RF.

However, as for "A digital-to-analog converter without S-video will look like crap." Still gotta disagree - most likely it will look no worse than the consumer is used to seeing from OTA which is composite and often degraded by weak signal.
That is true. The DTV-to-NTSC Composite connection would look no worse than current NTSC. But why?

Why should the consumer settle for "blur" caused by chroma & luma overlapping one another (composite), when DTV sends those signals separately? There ought to be an option to use a connection that preserves DTV's separate chroma/luma format (i.e. S-video) and feed that clean signal into the old analog set.

Like mine.

troy, it has become painfully clear that you have no idea what you are talking about and that you are completely misinformed and do not understand the first thing about either RF or coaxial cable.

believe what you like.

Perhaps, but this is not the way to convince me that RF is better S-video.

You fail to persuade.
