    Actually, you are likely correct, that the new birds will be able to cover as many or more areas as the space ways. But that makes your second part so very wrong. You can now use the entire bandwidth of the space ways to give an entire market every channel that is on the other main birds that the other main birds can't hit because of positioning, but the space ways can. Seems like a no brainer to me.

    I seem to recall an area somewhere around Lost Wages that had significant trouble getting their spot beam as well as some market on the East Coast that was only partially served.

    DIRECTV would probably do better to send an RB signal that way -- nore bang for the bandwidth (albeit without a transitional solution).

    "RB" (Reverse Band) is destined for CONUS coverage and according to Phil Goswitz SVP Space & Communications, DIRECTV, Inc., to carry what looks like International programming. Perhaps an eventual replacement for the 95w International dish service?

    No spotbeam capability is currently planned.

    NOTE: and in case you're wondering, I think the Reverse Band RB-2A's four large SB payload aboard D12 at 103w is(was) for advanced customer testing while the dispute with Spectrum 5 was settled and are not steerable anyway.

    Actually, if they use that for international, I'd say it might also be to replace everything at 119 as well. They may plan to move all services to 99 101 and 103 eventually.

    With that said,I see no reasons pothead can't be used for rb at some point.

    Could be;

    I was just referring to a brief comment Goswitz recently made on the issue of the future use of RB in addition to the main topic of Ultra HD as quoted in the conclusion to a March 2012 article in AdvancedTelevision.com:

    Why would they want to give up the 32 Ku transponders at 101, IMHO that makes no sense?

    That's where the confusion comes in.

    AdvancedTelevision.com in March has Goswitz saying Ku signals will eventually end.

    Yet later at October 1st Swanni also allegedly quotes from AdvancedTelevision.com (no date given) has Goswitz now saying the Ku band will be used in the future for Ultra HD channels.

    I think he probably meant that he sess sd mpeg2 from Ku ending, thus implying it will be retasked for other uses at some point than core sd programing that it is used for now. Possibly 4/8k. I also wouldn't be surprised if they use some bss at some point to get all the local sub channels. Maybe even some of the ku capacity at some point down the road, after its emptied.

    I think that the Ku band with its better signal to noise ratio and better ability to plow through rain fade (as opposed to Ka) would allow them to utilize higher order modulation rates (like 8PSK). This higher spectrum efficiency poses a great asset to high bandwidth 4k / 8k ultra definition content. Paired with new advanced codecs, there could be a capacity for a half decent lineup of 4k or even 8k channels.

    I don't think they can bounce 8PSK off of many Ku transponders today because all the old equipment deployed out there that doesn't have the ability to demodulate that type of signal. I could see it being a gradual transition as old receivers are swapped out, much like some Echostar birds have a mix of 8PSK and QPSK.

    Yes, but I wonder if the regulations for the Ku band BSS service will need to be entirely revamped first, as they were firmly established by the FCC and ITU long ago (AP30/AP30A standards) for 32 24 MHz wide transponder channels per slot (For "our" ITU region 2) at 9 degree longitude spacing.

    Doubt you can do much with only 24 MHz wide transponders for UHD even with higher level modulation like 8-PSK or new greater compression formats beyond MPEG-4.

    Isn't 45W outside the purview of the FCC?

    When would D14 be operational more or less.

    Very good question. 45W appears to be directly above Brazil. The filing indicates that the uplinks will be in Brazil. The US may be the coordinator of the geosynchronous orbit in the western hemisphere. Now who coordinates all the GPS and spy satellites running around up there is any ones guess.

    Nothing definitive yet, other than the launch window estimate DIRECTV filed with the FCC in the Schedule S document.

    From 1/15/2014 to 3/1/2014.

    Intelsat has a satellite at 45°WL that is authorized for service into the US and Canada, so I guess that gives the FCC some control. Also, since command and control, if not some uplink of content, could presumably originate in the US, that could also give the FCC a say.

    I would imagine that DirecTV also needs to file an application with Brazil to authorize broadcasting into that country.

    From the filing, all transmission (including TT&C run on the edges of the uplink band) would be from and to Brazil.

    The FCC generally doesn't hold sway to anything on or over international waters unless it is broadcast from a ship registered to the US so maybe that's what is going on here. IIRC, there are some Mexican broadcast stations located in the oceans that relay content under this exception.
