    Why can't transfers happen faster than real time? Claiming it is a "known fact" lends a lot more certainty that I think it deserves.

    It is a "known fact" that some of the competition (DISH, TiVo) are doing transfers faster than real time.

    No idea.
    It deserves 100% certainty, because it's 100% known. I'm not going to sit here and go around and around on this. Transfers from the DVR to Nomad happen in real time. Period.

    Sure, it COULD be done in less than real time, but that would require a new transfer mechanism on the DVR, since today they can only playback a recording to another receiver. I would think that they would get the Nomad on the market and stable before they start activating new transfer code on the DVRs.

    Maybe the processor in the DVR isn't powerful enough to add the DTCP-IP encryption to a faster data stream.

    Or maybe they don't want to tie up the network with to much bandwidth so that it won't bog down MRV?

    When the DVR is sending content to Nomad, it cannot also serve an MRV stream. So that is irrelevant.

    I suspect I'll still find it takes more than 4 hours to transfer 4 hours worth of stuff and therefore I won't own one. But anyway, we'll know someday.....

    Which processor is doing the encryption? I'm betting it isn't the CPU.

    Even if it were, you would think that an HR24 would do it more quickly than an HR21.

    Given that it's a 1:1 time for moving from the DVR to the nomad I think it would be logical to say that the nomad is doing the converting to whatever format it uses. It probably is setup how a DVD burner is where the DVR actually plays it and the nomad converts it.

    To copy off of the nomad is significantly faster.

    Sixto has described the best way to use it.

    You could in theory just pick something each night to queue up and then have it held on the nomad for a just in case. Perhaps if you have kids you could load up a couple of kid movies/shows that you know they would watch no matter what and then just store them on the nomad.

    If makes sense to me that it’s a two step process. That way it can transcode selected items even when the mobile device isn’t on the network, such as when I’m at work. I come home, start the app, and voilá, it’s on my device.

    If we believe Gizmodo about Nomad's on board storage then in theory after the first download to the device the only time length you really need to be worried about is how long the actual download takes. I’m guessing after the first use it goes like this; select so stuff to download, watch what’s on my device, and when I want new stuff I download from Nomad and select some more stuff to transcode, repeat. In this scenario with a little forethought you should never have to wait for more time than it takes to download to get new stuff to watch. Further, if 100 hours of stuff isn’t enough and the Gizmodo article is correct about additional storage via USB, I can have a lot of stuff waiting to be downloaded and never have to worry about transcode times...in theory at least. :)

    IMHO, Rube Goldberg would be pretty disappointed with two steps. Now if it transcoded, uploaded to a DIRECTV server where it’s sent via satellite to a duplication facility, it gets burned to a DVD, the DVD is then shipped via DHL, DHL delivers it to the local post office, USPS delivers it to the house, the app copies it to your desktop, and you upload it to your device...Now that Rube might have liked. :grin:

    The article is correct on both accounts for storage.

    Without a 2 part step every item you put on the nomad would have to be sent to every registered device you have which would not be very friendly to accounts with multiple people using the service.

    I'm making the assumption that the device that I use to select something to download will be the devices that gets it; even if I have multiple devices registered. I don't see how a one step transcode/download would be any different...unless I'm missing something.

    Video with audio isn't something that an HR2x can put on your LAN. It encrypts and dumps MPEG data.

    In contrast, most DVD recorders use NTSC video with audio and digitize that.

    In analog form. But I highly doubt that's what Shades was referring to, which makes this statement pointless. And I'm sure you knew that, too.

    No, its really not. You can also be receiveing a mrv feed from another drv, you maybe have other dvrs talking to other dvrs, you also could be downloading vod content. If one dvr was allowed to use more than its one allotted stream, then you start limiting what else can go on the network at the same time more so than its limits today, although I have yet to find the limits with my 7 dvrs.

    IIRC, the DECA "cloud" can handle up to 150Mbps. There is plenty of room for a single Nomad stream to be going faster than realtime. There is no way this is a network limitation.

    Guys, I'd like to remind you not to discuss each other, but to discuss Nomad. Thanks.

    OT, I know, but since it came up... I'm pretty sure the DECA cloud can handle ~ 250Mbps, based on the diagnostic screens.

    Not sure what that has to do with Nomad. Does it connect via coax?

    Not sure either. But if Nomad wants only connects Cat5 and needs to see your DVRs, I guess it could also connect via a DECA adapter, like an HR20-23.
