Why doesn't Directv use flash video instead of mpeg4

    Are you sure about that?

    I'm thinking there must be some reason the ATSC has established standards for DTH satellite.

    Big brother cares about almost everything that uses the spectrum.

    Just because there's an established standard, doesn't mean that the FCC is involved. Interoperability pretty much requires it .. heck, just take a look at RVU as an example (I know, not quite a codec). The FCC is championing something that is arguably a rival to RVU - yet there it is, the RVU standard.

    The transmission method is just the way the 1's and 0's of a digital signal are represented. At higher levels you have the actual codec. You can easily mix and match the transmission method and the codec contained within the transmission.

    I sure don't want my TV or Sat box to have to use Adobe to show me tv. Not with the security updates they always have to do all the time.

    I don't disagree with you regarding an extra layer, but even if it were packaged that way the updates would be largely transparent to you.

    None of what you talk about has anything to do with the signals that travel to and from the satellites through the public airwaves. RVU is all about the signal after it has been rendered in its final form. Allvid is a similar but considerably more ambitious run at the same thing. The FCC is bargaining with what they do have power over to effect changes elsewhere in the name of The Public Interest.

    What they have power over is how the airwaves are used and I think it goes a lot farther than simply assigning a frequency band.

    I can understand why you might think this, but it's not the case. I challenge you to show me a single official FCC document approving a codec for a satellite broadcaster.

    Here, let's make it easy in the doggy . . .

    Go find us the basis for your assertions, harsh. We'll be right here when you get back.

    I know that RVU isn't through the satellites .. My point is more in the word "Standard." As for transmission over air waves. MPEG4 just rides on top of whatever transmission or storage format that the underlying service provides. Remember, even DIRECTV has multiple "streams" on a single transponder "broadcast." Those streams are extracted from the broadcast on the client end. This is why at location 101° there are only 32 transponders but hundreds of channels. It's the channels that are MPEG 4 (MPEG2 in the 101° example I noted). What the FCC does care about is how those 32 TPs are broadcast back to Earth. DIRECTV uses a proprietary format (DSS) and I'm not even positive that required FCC approval, but that might have. What is certainly required is location of Satellite and a set frequency range for broadcast (and probably a few other Rocket Scientist things that I know nothing about). As long as those criteria are met, it doesn't matter so much about how it is specifically delivered.

    Now, the FCC is a big government organization. Could they stick their head in and cause trouble? Probably, but do they or will they? It doesn't seem so at this point.

    But if we used Flash, we could get interactive TV!

    Bring back Wink!

    (no, really, please don't.)

    Interactive TV is already available on DirecTV.

    I'm well aware of that ... I was just making a (very poor) joke about the olden days when "interactive TV" was the buzzword.

    Look up Wink Communications. There was a "partnership" way back when between DirecTV and Wink - it was painful to say the least.

    I don't need to look it up, I've been around long enough to have actually used Wink back in the day. ;)

    Then you feel my pain!! :)

    I remember doing everything possible to avoid the update on my receiver; it made it soooooo slowwwwwwwwww.... The current DirecTV Interactive is light years beyond Wink... doesn't take much!

    I believe Wink had already been rolled out when I came aboard, so I never knew what it was like without it. I did like how they used Wink to provide enhanced song data on the music channels, though. It was far better than what they have today.

    Directv does have more advanced interactive then wink but not as many services that wink had. There were many different channels that had there own interactive service. Like espn, cnn, bloomberg. I wish Directv had at least as many interactive services as Dish Network. They have like three different gaming channels were as Directv just has Gamelounge. I think you can even order Papa Johns pizza on Dish and there are a lot of enhanced tv channels on Dish that Directv doesn't offer. I know none of them are that great since I did try using them but at least Dish tries harder then Directv with interactive tv.

    I didn't find anything interesting yet with regard to DTH satellite, but I will cite the specification for HD Radio as an example of a place where the FCC settled on a proprietary CODEC.

    http://en.wikipedia.org/wiki/HD_Radio

    Look under the Overview section for "HDC".

    HD Radio is exactly the same as ATSC digital TV in this regard. Both are meant for free public consumption, so the FCC has to set standards. DirecTV's service is 100% private, so the FCC doesn't say anything about their signal as long as it's the right frequency and coming from the right location in space. They have no other authority over the technical aspects of the service.
