A brilliant concept, however I don't think I have ever come across even one DVD that has truly been encoded with "Pan-and-Scan" metadata. All widescreen DVDs I play on my 4:3 television, with pan-and-scan selected in the DVD player, always provides a 4:3 center cut, and that's all. For that matter, I don't think I have ever come across a DVD encoded with multiple scenes, either.
And we have the example like this Wizard of Oz release that deliberately disables pan-and-scan and viewer controlled zoom functions, because the content creator wants complete and total control over how his/her original concepts are presented.
If studios can't be bothered to encode simple scene-by-scene pan-and-scan metadata into DVD releases, why would they spend the extra time encoding scene-by-scene pan-scan-zoom information for multiple display sizes?

Therefore I invented "pan-scan-zoom", where the source provides some metadata about the area of interest, whose details should be preserved. The SD receiver can (dynamically) zoom in on the details, instead of down-sampling the whole image. It is like havingseveral virtual SD cameras on the scene.
