Hold the ladder, pal ! I'm climbing up with the box .

I'm betting it isn't lit up yet. They're just toying with us

I'll post pictures late, but as I can see the satellite have transponders on - 7,9,11,17,19,21,23 and 24,22,20,18,16,14 and three more even numbers.
Little akward because of DP LNBF.

EDIT. Pictures added.
It's hard to identify even tps in Hi-band, seems to me there are many problems with TWTA.

All MPEG4 fellas... You asked for more HD, right? The consolidation begins!

129W snapshot. 61.5W coming soon...

Ah, so that's how they have 5 HD channels on one transponder. I asked earlier how they were doing it but I guess I got my answer now.

New MPEG4 encoders? How do any of those 6 channels look?

 

[BobMurdoch]

It's real Mpeg4? Not the Mpeg2 masquerading as Mpeg4 in the flags?

 

[Kirby Baker]

Has to be at those bitrates, or else all HD subs would cancel.

61.5

 

[RandallA]

For the experts, what's a good bit rate for MPEG4 so the picture looks good? I believe it was 14 Mbps for MPEG2.

From what I know, 6-8. But thats obviously not an absolute. And I think the video I saw in that range was done via offline encoding, not real time.

 

[Scott Greczkowski]

I have not seen the video quality yet... But I did log in and grab these bitrates a few moments ago.

The video quality on them as far as resolution numbers are the same as they were before.

ESPN2 1280x720
NFL 1440x1080
NatGeo 1280x720
StarzHD 1440x1080
HGTVHD 1440x1080
FoodHD 1440x1080

Well starting this year you will see more broadcasters adopted the H.264 compression standard.

 

[Kirby Baker]

Just got home... have to say, doesnt look horrible. Nothing real glaring.. no big breakups or anything like that so far.

I assume you are not referring to OTA broadcasts. Not in ATSC spec.

Sounds good, of course for the ultimate PQ I guess we will need Sean Mota to give his review.

5 HD Channel on one transponder, wow!

dont you mean 6???

 

[Poke]

No not OTA just have been reading some info on what companies are doing with H.264.

You can find allot of info on this site.

[Kirby Baker]

Of course if the US had chosen CODFM (or whatever its acronym is) then we could have H.264 for OTA as well I think. Think its in the spec.

 

[mdonnelly]

Wouldn't the ESPN-2 signal have to be encoded in real time? Or are they only showing canned stuff?
