    Preparing is done on the nomad device. Downloading is then done to the local device via WIFI.

    I've typically found that initiating the preparing step on the local PC (connected to nomad) renders the fastest overall processing cycle time. I then just download to my mobile devices - which is very fast.

    You can also start the whole process via the mobile device via WIFI, but is seems to take slightly longer going through the whole process.

    But you mean only a small difference, right? I was wondering if the fact that I requested the download on both my phone and PC was causing 12 hour preparation times.

    In some of the earlier firmware versions, I had some programs that would hang preparing or start preparing and then drop off the list. In viewing those programs on the TV, there were reception glitches that were probably causing that. A 30 second reset was necessary to get those off that were hung.

    Deleting the program on the dvr and re-recording generally fixed it. But you can't always re-record a program.

    Requesting a program from multiple clients doesn't affect transcode time. . it only transcodes once and remains in memory until it's bumped out.

    Processing time will be impacted by someone watching a show using whole home. If you queue a show up for processing and then watch a show using whole home, processing will pause until Nomad has exclusive access to the DVR.

    I assume the same goes for DirecTV2PC? I don't have whole home, but I do have DirecTV2PC. Also, I assume that would be the case if someone was streaming from the Nomad too, right?

    Very possible thou I have not tested it with DirecTV2PC or streaming. It would be a plausible explanation for not seeing 1:1 processing times.

    There's something else going on there then because I've never had preparation time take more than 1:1 (4 hour program taking 4 hours), with download <16.5 minutes thereafter using the latest version.

    Well, if it helps, I haven't used DirecTV2PC all week. I have an HR20 connected to a WiFi access point, and an HR21 connected to a powerline connection. My WiFi is n only, I have nothing running g to slow stuff down. Once the program is finished transcoding, I can download an hour program to my iPhone in about 2 minutes. As I mentioned, the shorter the program, the closer I get to 1:1 transcoding time. It doesn't seem to matter, encoding wise, which DVR I am pulling from. Also, both of them stream very well to my iPhone and iPad using the Nomad. No stopping to buffer (except briefly after a trickplay).

    Thanks for the added detail.

    I'm almost wondering if the older model HR20 & HR21 content feeds perhaps slow down somehow on larger files...but that's purely speculation without any firm data to support it.

    I'm running HR24 and newer HD DVRs only...so perhaps that may account for faster processing somehow. I'm also running a gigbit network and WIFI "n". Not sure how all that comes into play for nomad processing speed overall.

    Not sure if this is the exact right place to ask, but since it's a nomad question here goes:

    My wife and I are a mixed family, technology-wise. She's Apple and I'm Android/PC (pre-Windows 8). How does nomad work between the 2? When Android phones/tablets start being supported, would I have to prepare a file for each type of device? Or is there one file prepared that downloads and works on all devices? Right now, does 1 file type work on the iPhone and a PC?

    Thanks in advance for your knowledge.

    One size fits all. The same transcoded show can be downloaded to PC's and iOS devices today.

    Great question actually.

    The nomad device transcodes recorded content in 2 steps.

    The first is to prepare the file into a compiled secure file internal of the unit.

    The second step is to "download" (via WIFI) that file into the format of the client program requested, which varies by mobile device.

    Example - if you prepared a program on your laptop and then downloaded it to the laptop, you could view it as desired. If later you wanted it on your iPad...you could request the same program on that device from the DVR playlist but only the download step would execute to meet the format of that particular mobile device (it's the faster step in the process).

    In my case it is a new install... on 3 different PC's and none of them will accept my login that has been the same since I first created an account on directv.com...

    I called them last night and am working with case management on the issue...

    I had this same issue after a past upgrade and we found somehow Nomad was removed from my DirecTV account. Once they added it back to my account I was good to go.

    Excellent Post!!! A Very Good Explanation of what goes on in the Nomad Transcode/Download Process. :)

    It does not vary by device, AFAIK. All shows are transcoded into the same file format, and the "download" step simply copies that file over to the mobile device, "as is".

    Based on file sizes and resolution, my guess is everything is transcoded to 720x480 MP4, at about 1200-1500 kbps.

    I am working with Case Management as well so let's hope we get their attention.

    CM is very good at getting Results. :)

    Thanks for the replies, everyone. I get it now!

    The only thing holding me back from purchase is Android support. I hope "soon" is soon! :D

    From what I know it does vary by device per the Resolution of that particular Device. :)

    Resolution is a function of transcoding, Rich, so that would mean the transcode would be different depending on the first client that requested it, which is not the case. Once a file is transcoded and in "Ready to download", it's resolution, size and audio bit rate are fixed. "Download" simply copies and encrypts it to the client that requests it, "as is".

    I actually wish iPad client "watch now" streaming could occur at a higher bit rate, if the Nomad device knew a "retina display" iPad was requesting it, e.g. It would probably be less work for the transcoder to sample at a higher bit rate, and since a streamed file is not stored, file size wouldn't be an issue. Unfortunately, that's not the case right now.
