Rca left everyone else at the alter

[oldtvman]

I know that during the developement of color television all the ideas and principles that Rca used for its compatible color system were'nt theirs alone. I wonder if any of you old timers can shed more light on the fact that after the fcc adopted the never the same color system, most manufacturers then decided to let Rca sell color to the public, not to mention the bad taste CBS had for having their line secuential system thrown in the trash. any thoughts?

Nobody else had the deep pockets (for color tv) Sarnoff had.

Those same deep (greedy) pockets led to Armstrong's suicide over the crap they gave him for his invention of FM. Truly despicable ego driven corporate behavior.

PS The real tragedy and irony of what Sarnoff did to this man is that if he had only embraced the technology then RCA could've made a fortune for themselves by selling new compatible radios and transmitters, just like what we now endure whenever a new recording format appears (Cylinder records-Discs-LP-Wire recording-RTR-4 track-8 track-Cassette-CD-Mini Disc-MP3........1/2" video tape-Beta-VHS-8mm-Digital.....Laser Disc-DVD-who knows what next!)

Where I can find the tragic story of Armstrong?

[Chad Hauris]

There is a book called "Man of High Fidelity" that has Edwin Armstrong's story.

Telecolor,

A GOOGLE search for "Edwin Armstrong" will provide several sites including a biography.

You're not suggesting we would have been better off with CBS's system are you?

actually the colour wars were dirty on both sides of course ..CBS wanted to delay television by promising "Color Now" while RCA wanted to get some money back on its investment in mono TV ....but the behaviour of Senate which was effectively bought off by Sarnoff to prevent CBS broadcasting in color in the late 40s set a new low.

There would have been a severe motion artifact with the CBS system. Moving objects would have color fringes that changed from field to field. Only today's digital processing would be able to fix this. Something similar to MPEG.

Yes but would there have been any electronic alternative besides the tri-color tube? I mean they are still selling them now, if something cheaper AND better than the color kinescope had come along wouldn't we have seen it by now after 51 years? So IMO even if CBS had gotten rid of the color drums or wheels, it would have just been another version of RCA's with it's own drawbacks, plus the non-compatability issue. I think the farther you get from 1954, the better RCA's system looked compared to CBS....Frenchy

I think I remember reading a story somewhere on the web where in 1951, one guy when he was a kid used to tweak the oscillators the family TV set to receive the CBS 405 line color system tests in New York every night, in black and white of course. It was kind of interesting. I guess if the FCC took the CBS color system instead, they could always tweak the B&W sets out there to receive it.

I think I've read somewhere that Philo T. Farnsworth suggested the use of a 625 line picture standard in 1941 when the FCC was settling on the TV standard we use today.

But on the other hand there would have been no phase error ..but then again extracting RBG would been fun ..and no saturation control....mmm...as for color fringing ...perhaps a quick check with the Early Television museum may clear that up ..as they have some CBS field sequential sets working????

Of course just as CBS did the blue banana trick RCA had swirling batons which very neatly showed this problem! ...aaaagh fun and joy

Having no phase error was true IF the camera tube discharged completely on each field. So, image orthicons worked OK, but vidicon cameras using a color wheel would have contamination from one color into the next, requiring a complex apparatus to store frames if you wanted to fix it. (Or I suppose you could cheat and change the colors of the filters slightly.)

Also, the bit about no convergence errors is only true if the power supplies in the receiver are good. They must have good high voltage regulation so the raster doesn't change size between fields, even if the scene is mostly one color. My old boss who saw the original CBS tests talked about this problem in receiver design. Also, the power supply had to be low ripple, because the 60 Hz line was not in sync with the sweep. The monitors we saw at ETF last year seemed OK in this regard.
