Black bars = screen burn in

[michalsm]

I've just got hooked up with HDTV form my loal cable provider. I noticed that when I go to the HD stations, I have the "black bars" on the top and bottom of the screen. I have a Panasonic 36HX41 tv which is crt instead of projection. I've heard that there's the possiblity of screen burn in on projections and plasma tvs if you watch widescreen video for prolonged periods of time. My question is, is my TV succeptable to burn-in as well?

Also, I've seen on some TVs that you can "strech" the video to get rid of these black bars but the aspect ratio is greyed out if I try to change it. This only seems to be blacked out when I'm receiving a signal from the HD converter box. I'm able to stretch the video from my DVD player. Has anyone else encountered this with this model TV?

Thanks in advance for any advice!

You have a direct view TV. Personally I wouldn't worry about it.

Ditto. Just don't leave a static image on it for long periods of time. Like games paused or leaving a news or stock ticker on all day long. Do a search for burn*, lots of posts on this subject. Also check the FAQ's if you haven't.

michalsm. What does your operating manual say about burn in, static images, black bars, etc? Although Direct View TVs are not as susceptible to burn lines as an RPTV or Plasma, they are not totally immune.

I'd like to hear from people who have new direct view HDTVs - what do the operating manuals say about burn in? Most RPTVs now say 15% of the time...

People are overly concerned about burn-in. I have talked with showroom floor people that leave static images and identifier icons on the screen all day long for months and they have very little trouble with burn-in.

Hi this is my first Post here. I am a Canadian Broadcaster. I will be launching an HDTV service in 2004 to compliment my current standard definition service. I have been doing a lot of research into the impact on HDTV consumers and burn in is one that I have done a lot of research on. Plasma of course is my biggest concern and has been addressed by many broadcasters in the U.S. Unknown to many consumers the black bars that you see on a HD service are on what we call a vary grade system. What this means is when the material is being broadcast in 4:3 or letterbox the upconverter actually varies the levels of the bars that are visible. The amount the bars are varied by is up to the individual broadcaster. Most broadcasters set this up so the viewer notices no change but if you monitor this closely you will see the change over a period of time.

You could contact broadcasters to find out if they are using this technolgy if not becareful with your Plasma's as they will burn in quickly. There is a way to remove the Burn in but this will effect your Luminance output.

I on the other hand will be going full 16:9 24/7 I feel that this is the best choice for my Network. This will include Commercial content as well. I will be deploying state of the art Technology that has yet to reach the Broadcast market place. This technology was derived from the US military. To give you an idea of the type of processing power I'm talking about one of these units contains 300,200 64 mb processors. Which will offer unsurpassed HD quality.

I look forward to hearing from you all and welcome any questions or comments that you may have.

Does this mean that you will NOT show movies/films in OAR??

[Broadcaster]

If viewrs want to watch any OAR they would tune to my SD signal which will mirror my HD. Any SD programing that appears on my HD service will be upcoverted using the product I have detailed earlier. NR,Pan & Scan, Crop and Zoom will be applied not just a simple stretch. It looks very good. Any HD programing on my SD service will be down Converted using the same technology but in a 4x3 format. The viewer will have the choice of what format they want to watch.

sorry
that didn't make any sense to me


will any films be shown in the AR of 2.35 (meaning that there will be bars on the top and bottom)

[57U]

I think broadcaster assumed an OAR of 4:3, not 2.35:1.

that's what I didn't understand, because he said "full 16:9 24/7"

[57U]

What he's planning to do is "reformat" any 4:3 material using a "state of the art" system, so that "everything" is 16:9.

I have seen this done with some success on some channels. Some do it better than others (ESPN hasn't had the greatest reviews for example)

Hey 57 could you point me to those reviews or let us know what people don't like about ESPN?

The ESPN HD programmes are just fine. I've read a lot of complaints on this forum regarding the ESPN, non HD signal being stretched...

I'm sure the search engine using the keyword ESPN should yield the appropriate threads....
