Makes one wonder why, if the 5th generation is perfect, there's a
need for 30% better reception performance.

Too bad there's no description of what the improvements are.

In any case, the LG 5th gen is hardly "perfect," if the Samsung Gemini manages to trounce it so convincingly in so many aspects, and if smart people needed to create A-VSB to get by some of the limitations.

My position for a long time has been that there's no reason to assume that 8-VSB reception cannot continue to be improved, since after all the limitations of the past and present are mostly related to how much signal processing can be done at reasonable cost. The denser the electronics become, the more processing can be done at reasonable cost It looks like this continuous imporovement is happening, which is a very good deal. Still in plenty of time for the 2009 analog switchoff.

Assuming, of course, that LG (in particular) and others don't continue to play the same game of hide and seek. We come up with the new solution, now you consumers try to find where it is.

The other interesting irony is that the more echo tolerance the receiver can handle, the more the receiver can work in SFNs, but the less SFNs becomer necessary for good reception in urban settings.
