SMPTE Television Color Test Calibration Bars and 1Khz Sine Wave For 1 Hour

SMPTE color bars is a television test pattern used where the NTSC video standard is utilized, including countries in North America. The Society of Motion Picture and Television Engineers (SMPTE) refers to this test pattern as Engineering Guideline EG 1-1990. The components of this pattern are a known standard. Comparing this pattern as received to the known standard gives video engineers an indication of how an NTSC video signal has been altered by recording or transmission and what adjustments must be made to bring it back to specification. The pattern is also used for setting a television monitor or receiver to reproduce NTSC chrominance and luminance information correctly. Originally conceived in the 1970s by Al Goldberg of CBS Laboratories, and previously categorized by SMPTE as ECR 1-1978, the development of this test pattern was awarded an Engineering Emmy in 2001-2002.

I remember this growing up. It might sound weird but I actually miss when tv stations would go off the air like this. I remember me and my best friend at the time would always try to stay up on the weekends/summer break until it came on.

For whatever reason this sound scared me shitless as a kid

gotta love when the color bars go

Man that's alot of swearing for 1 hour

This is still the best show on TV! Every episode stays consistent. It's fresh, colorful, and crisp. The best part is 0:00-1:00:01.

Oh, how I miss the good ol' days when TV channels showed this instead of them having shows 24/7 like today! 😥 Sometimes I'd stay up long enough when a channel signs off for the day just so I could stare at this masterpiece until I fall asleep!

[dead-aaa]

That's it?
That's the lost episode?
THAT WAS JUST A BUNCH OF CHEAP WALK CYCLES!

After approximately 29 minutes, 32 seconds, 31 milliseconds, and 5 nanoseconds, I have finally achieved what the rest of mankind couldn't. The Sight. I can now see 1 trillion new colors and I can fly and run faster than a cheetah.
