    Seems clear to me. (I work for large company). "Higher-ups" in support dept. are screaming "what the #@% is going on with all these support calls?" "We have to give away to many credits" "Add no more functions until what is there is fixed". "Make the call volume go down, then add more features."
    Engineers say "OTA works fine, it is MPEG2". "It is the MPEG4 that is still not mature." "Who the #@% decided to use MPEG4?" "It was a stupid idea".

    DirecTV is now the lead developer/user for this relatively new codec as used in real time encoding.

    MPEG4 has been around since 1998. If it's not mature (as far as technology goes), I don't know what is.

    While there are some uses of MPEG4 that are very mature, the transcoding of MPEG2 (HDTV) into MPEG4, real-time, is very new. And we're seeing lots of instability in HD as stations try to actually use it. In many locals forums, people are forever rescanning all their channels to recover "missing" HD data streams.

    So life is interesting and when it stops, we technologists invent something else to be interesting...

    Cheers,

    MPEG2 is, MPEG4 is not.

    I've seen a lot of tools to compress to DIVX, XVID, etc. Get the right software, right player, right settings and it works great. Introduce such errors that are inherent with broadcast transmission mediums and then see the results as we have now.

    If D* gave me the option to turn off receiving MPEG4 and turn on MPEG2 OTA, I would do it in a heartbeat. Both my boxes were relatively stable until my locals went to MPEG4.

    Lets slice this a bit finer. If they go another, and I hope they don't, will you be able to give details? ;)

    Keep in mind its not just the encoding to MPEG-4. Lots of equipment and programs can do that. It is doing it in real-time that presents the problems.

    D* has been at it just over a year now. E* has had trouble with it as well.

    Considering how efficient MPEG-4 is with bandwidth, I don't see the option being given with the next generation of HD using the MPEG-4 codec. The success (or lack of) varies depending on the DMA you're in.

    I know in Sacramento, CA (market #19) MPEG-4 is pretty darn good IMO. I have issues with News 10 KXTV (ABC) at least once an hour with pixelization. I've verified by talking to others in my DMA that it is an encoding issue. I assume DTV will address the issue and replace and/or fix what’s creating the problem.

    Others on this board have reported MASSIVE MPEG-4 issues. Looks like it varies a bunch market to market.

    Have you verified that it isn't an MPEG2 issue that everyone is having as well? I used to get blurps in OTA here all the time. The local stations had a devil of a time tracking them down. Sometimes it was the local encoders, sometimes the DD5.1 equipment, all kinds of weird stuff you wouldn't think of unless you were a station engineer. Now, two years later, things are much better, but there are still times, like a transition from a network HD feed to a local SD commercial to back to a network feed that might be SD then HD, that things don't work the way they should yet. And then D* has to take in all the crap with the good and make it MPEG4 with brand new equipment in real-time. Gets very interesting...

    Cheers,

    I would get similar packet loss with News10 when I was connected via OTA to the HR10. Now, that could be associated with signal strength but it was consistently the same channel when I would get numbers around 60-70 in the HR10 signal strength menu.

    Tom,

    I considered that... Oddly enough it doesn't appear to be a loss of the data stream entirely since DD5.1 stays locked and there is no interruption in audio. Video just gets scrambled for 5-10 seconds and then completely clears up. That's why I tend to point at MPEG-4 but I have no OTA gear to verify.

    What show consistantly has that happen? I get News10 through my OTA on my TV's ATSC tuner.

    Can you say proof of concept?

    Well, after my previous post, I went down to the basement to see if D* had fixed the locals here in West Michigan so I could watch NBC or PBS (HD or SD - anything) on the HR20. I was not to surprised to find the HR20 completely locked up with a black screen.

    WOW! This is mind blowing that we are all this worked up over OTA! Earl you poor poor man you, how do you have time to actually watch your HR20 when all you seem to do is answer all of our questions muy rapido?! And do you actually work for Directv, or just a tester/informant ? Oh and by the way Earl; if I were to be going to send D* a thank you card for turning on the OTA, when should I send that in the mail?

    This is probably like therapy to Earl. He can have a hard day at work, call over some friends to his place and say "hey, watch what I can do to these guys on this forum, they are like a hive of bees.....bahahahahahahahah!" :lol:
