There's some pretty interesting discussions being had over on the DIRECTV Domestic & LatinAm Transponder Maps: New Data 8/29/2012 thread.

Just sayin' for those who don't follow that thread (and they should be following that thread!).

Thanks for the tip, but you could have been a bit more forthcoming as to why we'd care on this thread. :)

Presumably you're referring to the fact that thread thinks it has found 9 local HD channels on a single D10 or D12 spot transponder?

Anybody have any insight to shed on that, whether it is true, and whether it has any relevance to CONUS transponder capacity?

I can't say I've personally paid a lot of attention to the spots on a technical basis. Do they have the same bandwidth as the CONUS transponders? Is this "new encoders as applied to spots". . . evidence of D* watering down HD PQ on locals. . .or something else entirely?

I go cross-eyed trying to understand half of it... but the implications are huge. Maybe not for the national channels, but certainly for the local channels. A good thing given the new carriage laws taking effect for all DMAs offered HD service next year.

Yes, that was what I was referring to...

Okay, fair enough.

Since by far most D* customers get their broadcast network (read "highest rated") content from their locals, I'd be just this side of gobsmacked if D* were to pick *there* to start monkeying with where the noticeable limits on PQ vs bandwidth are. I could certainly imagine that the "new encoders" discussion upstream would just as easily apply to spot bandwidth optimization as CONUS.

Let's see what our eggheads have to say about it. . .

Unfortunately, the local channels are doing that all by themselves...

It's bad enough when it was just SD sub-channels, but now we have to worry about HD sub-channels. My neighboring market just stuffed two HD channels on a single frequency. My market will most likely be doing that next year, and the NBC affiliate in Tupelo, MS just added ABC in HD on their sub-channel.

On the plus side, one DirecTV subscriber in the Tupelo, MS market described ABC as looking MUCH better on DirecTV than it does OTA.


Getting back on topic, I don't know if this effects the NATIONAL channels at all, but I thought that those who are interested in the technical aspect of the industry that read this thread might be equally interested in the discussion over in the other thread... hence the link from here.

In my (top 20) market, I happen to know the NBC channel feeds Comcast and D* directly by fiber. . . and DISH takes OTA. I haven't asked about the intermediate switching tho. NBC started feeding mpeg4 to the affiliates sometime back, even tho mpeg2 is what has to go OTA.

That new encoder doc waaaaay upstream also talks about mpeg2 encoder advances, tho I didn't pay much attention to that section. I'd think that might have some applicability to the locals OTA bandwidth allocation, tho small market locals in particular are *notoriously* cheap about engineering budgets.

Very interesting changes:

D12 TP20 & D12 TP21 now being used for linear CONUS HD.

Good news (if it stays this way).

That means they freed up some capacity for national HD channels?

How much would we have if this holds up?

Those 10-12 slots were unused for national HD recently.

This may seem silly and isn't intended to go off topic, but is there a chance for Pac12 Networks with this movement?

And I see there are some *TEST channels that were removed from it.... perhaps they tested the transponders with a few internal channels to make sure they were all right, and launched them to be "in production" now?

That means we have a bit more HD bandwidth. Nice!

It doesn't mean that at all. PAC12 will be found on one of Dish's satellites this year. :lol:
They already HAD the bandwidth to add PAC12. I think this is just looking towards the future, they have a lot more fish to fry.

Those test channels have been there for over 2 years ... :)

We've always wondered if they'd ever use that transponder for linear HD ... :)

So, they were just test and nothing else? Not push, not anything but test? Kind of odd, no?

I always thought it was used for insertion of local commercials on CONUS channels. They do push local commercials to my DVR, and use them on certain channels I believe.... is that done through channels/transponders you might not even be able to see? (Do they use Spotbeams for those pushes, would make sense too)

They're starting to slip CINEHD into 1060 slots now? That's probably a positive, so far as getting further up the max curve on that theoretical 44 new HD slots.

Is cinehd 24fps? You should easily fit 6 per TP then. Show time and Starz have been multiplexing big qty's of their movie channels for years now and I thought part of it was slightly reduced framerate.

Well, looking at the map (not updated yet for this morning), the pattern that jumps out is that if there are two or more Cinema HD on a TP, that TP only has 4 channels on it, not 5.

Dunno if that's a recent phenomenon or not.
