Evolution of NTSC Color Bars (1954-2009) - High Quality

With the new parameters for uploading video files, this can (theoretically) be seen in optimum 480-line height.

(NOTE: The colors may look different on some systems, based on such variables as different web browsers, i.e. Netscape / Firefox / Flock vs. Internet Explorer, or which Flash player, e.g. Version 9 vs. Version 10.)

In view of the upcoming demise of the analogue-based NTSC color TV system which was in effect from 1954 until 2009, here are recreations of key major electronic color bar designs, going back to the earliest days of the NTSC color system in 1954 (note how the -I and +Q matrices are initially bunched together before the 100% white bar is placed in-between them), all through the development of EIA RS-189A color bars (with and without PLUGE) and the iconic SMPTE bars (originally classified ECR 1-1978, later renamed EG 1-1990). Also seen towards the end is the new generation of color bars for the digital-based HDTV system which became the only means of transmission from June 12, 2009 onwards.

The tones heard go from the lowest to the highest with each different color bar design: 400 Hz, 440 Hz, 480 Hz, 600 Hz, 750 Hz, 900 Hz and 1 kHz. Volume set at -12 dB.

So the super at the beginning...that sure looks a lot like the Vidifont's two-font selection. You don't have one of those up and running, do you...?

@jcburns - Very sharp eye there. No, that wasn't typed on a Vidifont, but an incredible simulation. Wish I had, though, for ol' times' sake . . .

I only wish I could track down test patterns from the Japanese MUSE analog HDTV broadcasts. I've found a couple of sign-ons on-line (recorded on VHS using downconverters, apparently), but that's it.

I like this! See? Colors. Nice shape. I like the theme song. "It's A TEST PATTERN!"

I like that bit from Dinosaurs, but I do like the test patterns.
