Broadcast whites....why?

I understand that Broadcasters can get in trouble with the FCC if they broadcast images that have a white level over 100.

But what the hell is the danger?

I don't understand the fuss. What happens (besides the image looking bad)?

Do people eyes burn? Do TVs explode?

What's the deal?

Have you ever seen a commercial that buzzes uncontrolably when a white screen comes on. T hat white screen if above color safe areas causes an audible buzz that can be quite annoying, althgou I admit that I didn't know you could actually get in trouble with the FCC.
 
broadcast standers are important to keep. It is like sending a loud over modulated audio tone. It can really hert some equipment if it is done to often and for two long.

It's a standard. You can't have a bunch of mish-mash.

It's kind of like the no animated signature rule here at DVXUser. It would just end up being a distraction and hurting your eyes.

:grin:
 
Yea!! some local commercials here on Time warner cable for some reason, when the screen goes white, it starts mushing up and a loud Buzz is heard.....

Thats why that happens, i thought my TV was going on the fritz...

I would try it. Send a signal to a set for a prolonged amount of time. and Boom!! Maybe we just uncovered the next terrorist plan..
 
it is also important to work within broadcast standards because some TVs (like a certain Philips LCD HDTV I own) automatically blacks out the screen when white level is too high to protect itself from damaging signals.

Now I don't get that. I was under the impression that a station will just crush your blacks, and bring down your whites before airing the footage.

Is that feature in case the station simply didn't do that? Who would get hit with the fine in that instance, the person who submitted the illegal footage, or the station who didn't bring it into the legal levels?
 
Damned good question TC...I've wondered the same thing. My new HD TV goes to black and mutes the audio when it detects any input written by people with less than a 70 IQ, It won't even turn on on 90% of the channels.

i dont know who would be liable. ive come across illegal white level on DVD supplemental material a few times. and confirmed the reason for the blackout by using the HDTV as a client monitor on my edit bay for a short time.
 
I use to work for a cable station and it was a big deal. Now we do have a compressors that the material goes through before it gets modulated, but if the footage dose not have the right levels it will come out of the compressor or processor looking kind of funny. So the answer is yes and no. As for who would get the fine. Well the station would for letting it air. But you better believe that the station is going to fine you. They are not going to carry the buck so to speak.
 
Why is it kind of scary?

Unless you mean that at any time, sounds and images could be pumped into our TV screens that would make us blind or def.

I guess that is kind of scary.
