Re: [PATCH] dvb-sat: add support for North American Standard Ku LNB This is the standard LNB used in North America. It is designed with L.O. Freq of 10750 MHz. Intended for the North American FSS Ku Band, 11700 to 12200 MHz.

It is standard, standard for North America at least ...

Anyway, it's just a name...personally I have no preference

what ya name it, as long as it works and people here no longer

have to jump through hoops getting their hardware to function

properly in linux.

I'll send a modified patch tomorrow.

Thanks again for the support Mauro,

Bill

The patch it self looks good. The only thing that I'm not comfortable is
the name of the LNBf, as "STANDARD" means that it was standardized by
some telecommunications organism.

A quick google seek for "lnbf ku band united states" pointed to this site:
	http://www.galaxy-marketing.com/ku_band_lnbf.htm

With describes different models for K-band satellites within North America
and United States. I might be wrong, but it doesn't seem that someone
standardized it.

Instead, it seems to be a de-facto standard made by the hardware
industry, and that not every single LNBf used there follows it, as
some of them use different LO frequencies.

Anyway, if this was standardized by some organism, the better would
be to name it after such organism, e. g. supposing that this was
standardized by ATSC as "type 1", it could be called as
"ATSC type 1".

Otherwise, would be better to name it with something like
"North America LO10750", in order to reduce possible future
conflicts as we need to add more LNBf for US there.


Thanks,
Mauro
