    NASA Readies Ultra HD TV Channel for Satellite, Cable, and Streaming

    NASA and Harmonic have revealed plans to launch an Ultra HD TV channel. NASA TV UHD will offer 4K content to a variety of platforms.
    . . .
    Exact distribution partners for NASA TV UHD have not been announced yet, but Harmonic is working with pay TV providers to offer the channel on satellite, cable and optical networks. In addition, NASA TV UHD will also be available to stream over the internet and will require a connection speed of at least 13 MBps. The channel is set to launch on November 1.

    I'd just be happy to get NASA TV in HD. For some stuff, it doesn't really matter really. I don't care about things like "Education File". But launches, rocket tests and spacewalks? Absolutely.

    So will this be the first UHD linear channel on DIRECTV?

    Seems reasonable, since no others have been announced other than that demo channel that's probably just a loop of the same content over and over again. The pictures of Pluto coming in are pretty cool, they can only look better in UHD.

    Since they don't have the RDBS LNB publicly released, and may not even have the transponders lit up, they'd probably use Ka for this at first. If so any HR34/HR44/HR54 would work with a 4K RVU ready TV or C61K.

    It would be kind of funny if Directv had the NASA channel in UHD before they had in HD :)

    Would a 4K channel be compatible with regular HD? Or if they did add only a 4K channel, those with 4K sets would get it and the rest of us would be stuck on SD?

    No, the HD receivers couldn't decode it. One would imagine they would add an HD feed at the same time so that scenario seems unlikely.

    is there any setting in C61K to output in HD instead of default 4k or will do that automatically after HDMI negotiation?

    My understanding is that if the C61K receives a 4K channel it is capable of outputting it in 4K only, it will not downscale to HD if the HDMI 2.0/HDCP 2.2 negotiation fails. It will function as a normal HD client when connected to a HDTV, so it will display HD and SD channels, but if there was a NASA 4K and SD channel and no NASA HD channel (I doubt they'd do that, but hypothetically) you could only view the SD version if your C61K was connected to a HDTV.

    The C61K also does not upscale HD to 4K, it feeds HD to a 4K TV and leaves it to the TV to do the upscaling. Which is too bad, the (potential) quality is improved when the scaler has access to the original MPEG4 stream. Probably the chipset they used doesn't support it, but I would guess that future generations will add this ability. The designers of the first generation 4K chipsets were probably more concerned with just getting the 4K part right, and will add the bells and whistles later.

    I was under the impression that the C61K will up-scale 1080p to 4K

    Maybe it will with 1080p, but that's only used for PPV. People probably care more about upscaling the 720p and 1080i content that all of Directv's channels are delivering, not Directv's overpriced PPV content.

    I think it would be very easy test for owner of the C61k - connect it to HD [1080] TV and run 4k demo ...

    C61K connected to 4K TV and found the following

    C61K will not upscale 720p/1080i/1080p to 4K.
    It will only pass them to the TV at their native resolution, or 1080i for all on air content at 720/1080i, and for 1080p (ch 125) it will pass it at 1080 24p.

    I can take a 4K Demo Directv recording at let it go to the TV at 4K. It showed 3840x2160 24p.

    I can take the same recording and force 1080i or 720p, but not 1080p.

    thank you for the tests

    any chance to connect the C61k to normal 1080i TV, not 4k ? to see if 4k recordings will play with downrezzing

    Yeah I'm curious if it will downres 4K to 1080 if not connected to a UHD TV. Or does it act like 3D on DirecTV, where the software just prohibits it?

    I know on cable you could still tune 3D on a non-3D TV. You would have to sit rather close to the TV and cross your eyes a certain way until the side by side content sort of merged, and it would look 3D more so in the middle, but that was hard on the eyes!

    The way that current HD set tops easily downres to SD makes it seem it should work this way. It's not a completely new thing like 3D was.

    It would be simpler (and better) for DirecTV to do the conversion and have a separate HD channel from the UHD. That way ALL subscribers with HD receivers could see a HD feed without needing to downconvert the content at each receiver.

    And they would be able to get rid of the SD version too...

    Do they ever get rid of SD channels? Customers who are SD only might complain...

    I know Directv is going to want to push them to upgrade eventually, but they don't have any pressing need to free up that Ku bandwidth on 101 so I could see them waiting many years before they do.

    NASA SD tv is in mpeg4 on 99 or 103 so.....

    How many customers are out there that have only SD mpeg4 equipment with a dish that picks up 99 and 103?

    There's only a couple channels like that.
