Why are station logos displayed even though they cause burn in on Plasma TVs?

[donesprague]

The documentation with our new Plasma TV specifically calls out the burn in problem associated station logos being constantly displayed. Burn in a permanent image that is burnt onto the Plasma display because of things like station logos and financial stations with stock ticker having a constant ticker background. I understand that things like stock tickers might need to have a constant background. I don’t understand why stations need to put their logo at the bottom right of the screen when they are showing programming.

Can anybody explain why station logos are constantly displayed?

Could it be that station managers don’t realize they are causing a burn in problem? Could it be that they think viewers are unaware of the channel they are watching? Could it be that they don’t care that logos causes burn in which ruins the TV? I hope they just unaware.

Does anybody have another possible reason for station logos to be there burning in on Plasma TVs? What am I missing?

The Logo's were there first.

The material they broadcast is copywrited.

It really isn't a problem unless you leave the T.V. on the same channel hour-after-hour-after-hour and follow some basic breakin setup.

Could be to protect copywrited material.

Could be that normal viewing patters are no problem for the vast majority of TV owners with Plasma TV owners being a subset of that majority and with even only a small subset of the subset of the majority of TV's being used in a manner that will cause burn in.

CRT based TV/Monitor's also had the same issue of burn in for static images, but in 50 years of TV viewing the ONLY "burn in" I've witnessed are on business computers running the same image or frame layout for data all day long day after day.

All good comments. Good information about burn in.

I know that logos have been displayed for years. However; originally they were just displayed occasionally and only a few second or minutes. That was annoying and some times covered part of the programming. Now the constant logo is very annoying and at times covers some of the program. The logos don’t protect the stations from copyright violations. They do advertise the station and they do annoy.
Periodic logos would be better. Smaller logos would be better. Faint logos would be better. No logos would be best. They would eliminate customer dissatisfaction with the people who decided to place the logos.

I will follow advice about burn in but will remain dissatisfied with the stations for placing the logos.

Digital on-screen graphic

A digital on-screen graphic (DOG; also known as bug) is a watermark-like station logo that many television broadcasters overlay over a portion of the screen-area of their programs to assist viewers in identifying the channel. They are thus a form of permanent visual station identification, increasing brand recognition and asserting ownership of the video signal. In some cases, the graphic also shows the name of the current program. Some networks use an on-screen graphic to advertise later programs in the day's television schedule—this is generally displayed after the opening, during in-programme credits, and when returning from a commercial break.

From its inception, cable network VH-1 commonly utlitzed a bug in the corner of the screen while broadcasting music videos for copyright purposes. MTV also did the same, beginning in 1993. MTV first began using a bug while videos were shown on the program Beavis and Butt-head. http://en.allexperts.com/e/d/di/digital_on-screen_graphic.htm



Because of the graphic, it is easy to identify the source, i.e. protect the copyright of the transmitting station.

Fox News may have set theirs to spin to prevent this burn in?

All good info here. I work in a TV station and the logo or "bug" is used for copyright protection and station branding. We also keep the bug at a low opacity to keep burn in at a minimum. We have litterally a hundred sets here at the station all tuned to the same signal with no logo burn in.

The networks are in cahoots with the manufacturers to drive up sales!

I seriously forget what channel I'm watching if there's not a bug. :eek:

I'll use the menu, select a show, and it's commercial. Ok. Whatever. But a few minutes later..."What am I watching again?"

Modern plasmas are much better at preventing burn in.

Channel 3 here in Norfolk had the logo for a local law firm in the lower right corner for the entire Redskins preseason game. This wasn't a watermark but just as bright as if it were part of the programming. It was very distracting and often covered up what you wanted to see (assuming you wanted to see anything with the Redskins that is).

With ad revenues going down, expect this more and more. I personally will make it a point of not using whatever is being advertised in this manner
