    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.

    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?

    As many here have said, it is a process. And as with all processes, timelines can change. The first step is to get national programming off 119, which is largely done. Then, SD locals will be turned off if the come from 119. There's every indication that a subset of SD nationals could stay on 101 for some time. Remember these are channels that are used on airplanes, RV's and other special purpose installations.

    However just because there is "some" SD national programming on 101 doesn't mean there will be much. It also doesn't mean that the average person will have access to it.

    The real truth is, very few people really understand the whole timeline and those who do are rarely going to discuss it.

    One thing I can tell you, some people are claiming that the 101 satellites are going offline. That is 100% patently untrue.

    Thank you, Stuart. It never occurred to me to explain that the 101 Transponders will remain active, in one form or another. I didn't realize that thought was even out there. The satellites may change, but those 32 transponders will remain, from what I observe.

    Yes. ALL Directv receivers have a separate network tuner, and since it doesn't need to receive HD programming it doesn't need to support DVB-S2. So a single tuner receiver actually has two tuners, the dual tuner DVRs have three, the HR34 & HR44 have 6, the HR54 has 8 and the HS17 has 16.

    In some cases they are chips containing more than one tuner - the HR34/HR44 have two three tuner chips, for instance. Some single tuner receivers have a dual tuner chip, others have two separate tuners. Since a DVB-S/DSS only tuner was older and therefore cost less, they were used since Directv wasn't concerned about whether they would need to continue to support DSS for guide data as long as those receivers were in use.

    Hello Stuart Sweet,
    With the programming removal from the 119 satellite it makes less than zero sense to believe that the 101 satellite would go offline. There would be too little capacity for the 99 and 103 satellites to handle. With only the 99, 101 and 103 satellites it becomes easier to align and realign, when necessary, for optimum signal levels.
