Definition of HDTV: here we go again

So what IS the minimum resolution requirement for something to be called "high-definition"? We kicked this around last year (and then we got kicked around in the comments) when discussing "Truth in Advertising". On on hand folks believe that any display that can show 720 horizontal lines qualifies as high-def, meaning that XGA (or 1024 x 768) should be considered high-def. Our contention is that XGA is a computer resolution and that the more traditional 1280 x 720 (or higher) would be required for the HD moniker. We'll be running a poll on this one later today, but before we do, take a look at Henning's thoughts over at HDBlog for his insights on the subject.
