there is no standardized definition of HD. HDTV is 720 or 1080, but HD is simply a generic term meaning better than standard definition.

- p1mrx 12y agoThe only exception I've ever seen to the "HD >= 720 lines" rule is that of ignorant video uploaders.
- lacksconfidence 12y agodo you have any official sources? I would love to update the related wikipedia page but can't exactly cite a hacker news comment.
- p1mrx 12y agoThe best I can find is this: http://www.ce.org/CorporateSite/media/Standards-Media/DTV_Definitions.pdf http://www.ce.org/CorporateSite/media/Standards-Media/DTV_De... But it's consistent with your previous comment, in that it only defines HDTV, not "High Definition" as a generic term. But given that HDTV is what caused "HD" to enter the vernacular, you'd have to be pretty dense to call something HD Video when it doesn't meet the HDTV standard. That would be like burning an .avi to a CD-R, and calling it a Digital Video Disc because it's a disc with digital video on it. Interestingly, the PDF above suggests that you could have a 960x720 4:3 display that shows letterboxed 16:9 at 540p, and still call it an "HDTV".
