    They are dropping MPEG2 SD in phases, so depending on where you live your locals will disappear this spring/summer and eventually all MPEG2 SD nationals will be dropped. We don't know exactly when, only that it will be by the end of this year.

    They are only dropping the MPEG2 SD duplicates, channels that are currently MPEG2 SD only will become MPEG4 SD. They are not and never will go "all HD". There are some channels that not even available in HD, and others where for various contractual reasons Directv does not make them available in HD. That won't change when they drop MPEG2 SD.

    Any idea on whether the limited SD channels carried forward will stay on Ku (w/MPEG4), or will D* force antenna upgrades (for those with Ku only LNBs) along with the receiver upgrades?

    Its likely the SD only channels will be mostly or entirely carried on Ka. If you have a Ku only LNB you will want to upgrade if at all possible, otherwise you will only have those channels that Directv decides to put on 101 (110 & 119 are going away by the end of the year)

    It would seem that leaving the SD programming on Ku would be less of an impact (big bang integration) for RV systems. On the flip side however, it would be worthwhile to put HD programming on the repurposed Ku transponders; so RV systems currently limited to SD programming would be upgraded to HD. Are there transponder resource efficiencies gained in implementing one way or the other?

    They are getting rid of ALL duplicate channels, so if they left all the SD channels on 101 they would be mostly stuff no one wants to watch since there aren't any popular or even semi-popular channels left on Directv that are SD only. That would hardly please RV owners.

    Even if you like the selection of channels on 101 initially, they could always move a channel you really like off 101 at any time so it isn't something you'd want to count on long term. I think RV owners who can't upgrade to a Slimline for whatever reason are going to need to switch to Dish.

    As Slice so well explained, the main thing they are accomplishing is to stop wasting spectrum by transmitting two different streams of the same program content. It also will allow them to convert at least some of the Ku band transponders to new modulation and compression methods. They can keep using DSS modulation on some of the transponders and have the video streams compressed using mpeg4, but that is a combination we have not seen with DirecTV. Up to now, all of the transponders whose programming streams use MPEG4 compression, have used A3 modulation. It will take all year to weed out all of the old SD only customer equipment, but after doing that for a specific DMA, I expect the SD locals for that area to be taken down.

    As for the guide data, as near as we are able to figure out, they are probably going to keep some Ku transponders up with DSS modulation to carry Network Information, software, and guide data. We can't predict what transponders will carry that information. All we can do is follow it to where they put it. If they find a way to put all of that stuff on A3 (modified DVB-S2) transponders, then most of the data we publish here in the Resources Forum, that requires up to date information, will probably disappear.

    Fortunately for your data gathering process, Directv does not have the option of dropping DSS for the guide data. Some HD receivers and standalone DVRs have network tuners that are DVB-S/DSS only. Maybe some day in the far future they will obsolete the H2x and HR2x, but I think they will probably keep supporting them as long as they offer satellite.

    If they cannot mix MPEG4 and DSS for some reason, there may still be some limited use of MPEG2 SD on those transponders (assuming they don't just have one transponder that carries all the metadata and no programming) We'll find out in less than a year.

    I don't understand how they can have an HD receiver that is physically only able to tune DSS. It wouldn't be able to tune in any of the current HD channels. Other than the physical characteristics of the tuners, everything else would in the firmware. Unless the the Ku band tuner is limited, when the Ka band is not. If that were a limitation. they would have trouble with the A3 HD channels on 119.

    Do these receivers you are talking about have a tuner for the network information that has different capabilities than the one that receives program streams?
