The proposal from Vince is a more rational structure and maintains the semantics of groups of bands. Can you clarify exactly what you mean by "groups of bands"? Previous messages talked about how the US TV spectrum is indeed a set of four separate bands. However the EuroDTT spectrum is not, it's a single contiguous band. There's no need to be throwing away information to save a few octets. What information is being being thrown away? This is not about saving octets. (f1, f2, p1, p2) is at best the same as (f, p) and when the PSD slope is non-zero it's slightly less efficient. I need the ability to represent a frequency discontinuity *within* a nominally contiguous band, ideally without having to treat that band as if it were actually two or more separate bands. If your intention above is to allow the full information about the _channel plan_ to be represented that's OK, but that's _not_ the right semantics for representing a non-permitted channel in a contiguous band.
