Here's one for the older wrinklies on this forum. I was recently asked to
explain where the 16:9 aspect ratio of HD and now many SD TVs came from.
To date I have the following.
NHK and maybe Sony proposed 5:3 for HD (15:9). This was regarded as the
Golden Aspect ratio used in art. USA & Europe showed concern, (putting it
politley), and it was suggested that the aspect should fall between 1.66:1
and 1.85:1, being the then widescreen film aspect ratios of Europe & USA.
This suggested a ratio of 1.78:1, which was discussed I believe by SMPTE &
EBU. It was agreed globally that an aspect ratio of 16:9 would meet this
demand, and so it was born! In HD 1035 lines changed to 1080 to get
square pixels and everyone lived happily ever-after. Except of course there
were then suggestions of 2:1 and 2.4:1!
Can anyone throw more light on the origination of 16:9 or confirm the
