And I don't ask that to support the idea that upscaling makes it HD; I just don't know the actual meaning of 'HD'.
Are you talking about the specification standard for the definition for "HD" or are you asking for an approximate definition of what HD should be at a minimum to be, in good faith, a reasonable effort to have been produced in high definition?
Typically, 720i is the minimum for "HD" with no reference to actual bitrate or content.
