On which channels do you have audio dropouts?

    In PCM mode mine are more like skips. A few times an hour, but noticeable. Happens on both receivers HR24 and H25. I'm convinced it's something in the stream that the decoders in the STB or something in my SWM setup does not handle well. Does anyone with a non-SWM system have the same problems?

    You should stop there, as it's in the uplink transcoder.

    i have no room correction modes such as Audyssey on my receiver and the dropouts still happen so i can't blame that as the culprit.

    who's the Sgt. Schultz at DTV saying "I hear NUTHING!!!!"

    Not sure who you're talking to, but the broadcast engineer that I do reports back things like: the tech svcs guys looked at the transport coming from the station and they see lots of PCR and some PTS errors.

    well then you would think that they are trying to do something to rectify the situation.

    I've been working with them for a very long time about this, can say they are spending a lot of effort on this.
    When the source of the problem is coming from someone else [the providers] it isn't within their total control, which makes it "slightly" harder.

    if the source of the problem is coming from the providers then why is it that i never encountered the same problem with Dish, just out of curiosity?

    I don't know what Dish is doing, "but":
    The problem mainly comes from errors in the MPEG-2 feed from the providers and how [poorly] the MPEG-4 transcoder deals with them. "Sometimes" resetting things at the uplink will resolve the problem, so it can be on the DirecTV end, but mostly it's from the providers.

    As to why another service doesn't have the same problem "could be" that they're using a transcoder from a different manufacturer that handles these errors better.
    MPEG-2 seems to be a bit more tolerant of these error, so they're not as noticeable, which tends to have the providers say it isn't their problem.
    As customers, it is "our problem".
    DirecTV has invested millions in Harmonic transcoders, and "I believe" is doing everything they can to address this.
    Dish may be using the tandberg encoder. :shrug:

    I worked for Harmonic a long time ago, and would gladly throw them under the bus over this.
    My local NBC is [has been] horrible and they use a Harmonic MPEG-2 encoder that Harmonic has checked out and claims there isn't anything wrong with it [according to the station], and this feeds the Harmonic MPEG-4 encoder which has the problem.

    Audio dropouts were as bad as I had ever experienced tonight during The Sing-Off on my local NBC station (WNCN, Raleigh). There was at least one dropout every three minutes for the entire hour.

    This is so clearly a problem with Directv's feed...if they try to tell you otherwise you should let them know you're not an idiot and either want out of your contract (since they are not providing the service they promised) without a penalty which you have the right to; or you want a credit for the remainder of your contract period to put up with the crappy audio.

    It's obviously not an end user problem because when the DVR is constantly recording the audio stream and if it was some intermittent problem with the end users equipment or cords or whatever it could not be reliably reproduced...but it can! The second audio drops out for you all you have to do is rewind your DVR and it will happen in the exact same spot every time...because the feed comes directly into the box and the DVR records that feed just as it is...it is a Directv problem.

    Capitalize on this people and make Directv pay....they WILL credit your account for you or they also have no basis to keep you in the contract since the audio is crap. The more people that take advantage of this will force Directv's hand to fix the problem with their providers.

    They are both using Harmonic, unknown as to whether or not a few older models are still in the 'production' of their feeds.

    But there is a MAJOR difference in how the streams are manipulated and sequenced which I'll get to in a minute.

    ALL repeat ALL feeds going through DirecTV have audio dropouts. IF you haven't heard them, you simply haven't spent enough time or aren't 'sensitive' to them (or don't have outboard equipment that may be, or exacerbates the problem) . This includes all those originating as Mpeg2 (SD or HD), those originating as Mpeg4 (SD or HD), those being transcoded at DirectV, being fed through Ku or Ka, those with or without Dolby Digital audio. ALL means ALL, period.

    So, what is the difference between the DISH plant and DirecTV then, if they use the same encoders? Well, for one, the digital routers (also made by Harmonic), of which DirecTV has and uses on a constant basis, and of which DISH DOESN'T have.

    What does this router do? Well, for one, how does DirecTV 'clone' all those RSN channels for their MLB game subscriptions? How do they quickly and easily map those channels around, handle the 'Sunday Ticket' feeds without a battalion worth technical folks patching and re-patching those feeds?

    The Harmonic router system. Which exact one they have, or if it's something Harmonic 'whipped up' out of their base product line, I have no idea; when it was installed they did issue a press release (this was at least 5-6 years ago), so what they actually have in place now is unknown.

    But it is the major difference between the two plants. It enables DirecTV to map things 'on the fly', while DISH relies on 'hard wiring' things. Obviously, it's 'integral' to DirecTV's operation, and as long as only a 'small' percentage of customers are highly bothered by it, they can 'blow the problem away', so to speak.

    The question of 'will it ever be fixed' is fairly interesting, as there are more customers than just one (or two) for their systems today, as major cable MSO's are beginning to transition to Mpeg4 quite literally as we speak. Bottom line, THEY WILL NOT PUT UP with this type of nonsense and will have to fix their system(s) pronto.

    Since I've turned off the Dolby Digital option on the DirecTV receivers and went straight PCM a couple weeks ago, the "brrrippps" are gone. I've decided the trade off of lower fidelity is worth it.

    Just wanted to throw in my two cents. I just joined this forum this evening after being a DTV customer since about April of this year. I have been having two audio issues since day one; one second drop outs on just about every channel and some audio sync problems. I've had both problems before I set up my HT with a receiver and after. I'm a little shocked from the long running post that this hasn't been taken care of yet. I might be "new" to DTV, but I was with them from the very beginning (early 90's) and only switched to cable in late 2007 after divorcing and moving to an apartment. I have never had an issue like this and it's a big time bummer to have to deal with. Anyhoo, I'll be keeping a close eye on this thread.

    Hello Everyone,

    I am currently experiencing audio dropouts on History HD 269 no dropouts on History SD 269. No problem on HDNet HD 306 (I know no SD but I am trying to be consistent). I have tried some other HD channels in different areas and have experienced no audio dropouts.The show has changed on History HD 269 and the audio is now perfect again. The time frame was more than 10 minutes of bad audio.
