Talk:Safe area (television)

message: Additionally, the graphic in this article showing the safe area for PAL 720x576 is incorrectly illustrated.  It is created as actual 720 pixels by 576 pixels, not taking into account PAL's pixel aspect ratio - thus causing it to display in wikipedia as narrower than it should (since computers use square pixels).  The equivalent PAL dimensions when expressed in square pixels should be 768x576, in order to accurately show proper 4:3 aspect ratio.  See Pixel aspect ratio  The same would be true for NTSC 4:3, which would be 720x480 non-square pixels, but displays properly on computers at 640x480 or 853x480 for 16:9 video, due to proper horizontal scaling of nonsquare pixels.
As a broadcast engineer, I oppose merging Overscan and safe areas.  They are two different concepts.  Safe areas are largely made to compensate for overscan issues, but is its own thing.  TeamScottSmith 17:27, 10 February 2014 (UTC)

message: There is a suggestion to merge "Safe Area" with "Overscan".  I think they should remain separate articles.
I think the 5% and 10% refer to distance, not square area.  So if you have 480 lines, the title safe lines are from 49 to 432.

message: This article doesn't make sense without a diagram. 
Anyone consider adding a diagram since the bot destroyed the existing one? I would, but I only know the percentage of screen area that is title safe, I don't know what the margin percentage is.
:I have no idea if things are the same in Britain, but there is a safe area diagram with percentages at this site http://www.bbc.co.uk/commissioning/credits/position.shtml . RadicalPi 06:04, 18 September 2006 (UTC)

message: I Support merging Title safe and Action safe into safe area not overscan, as they fall into policy based techniques rather something that's part of broadcast television's hardware technical spec like overscan. Framing shots, graphics and captioning decisons are based on safe area standards. Eventhough overscan is the reason safe areas exist they're still separate topics. -IncidentFlux 21:45, 13 September 2007 (UTC)

message: In the Hollywood I knew, at least, the screen areas were called "safe action" and "safe title," but a film so-composed was said to have been shot "TV-safe." Is this nit worth including?Jim Stinson 03:24, 12 July 2007 (UTC)
thread_title:  Terminology 

message: "Safe area" is also the designation for a United Nations protected zone. There should be some sort of disambiguation link.

message: It would be handy if someone could post to this page the pixel co-ordinates of these "title safe" and "safe areas" within the 720x576 section.  —Preceding unsigned comment added by 132.185.144.124 (talk) 09:52, 19 February 2008 (UTC)

message: So what exactly is the reason the clean up tag? Does the person who put the tag on even remember? That person ought to read WP:RESPTAG. Cromulent Kwyjibo (talk) 21:35, 8 August 2008 (UTC)

message: I think that this article should at least mention that some of the "Invisible area" is used for transmitting Teletext. --109.228.177.118 (talk) 11:54, 26 December 2011 (UTC)
