It could be, but again, SD IRDs do not have 8PSK capability, so Dish has not ever or will not ever (nor can they) mix 2 HD 8PSK signals and a SD QPSK signal on a transponder - thus your Good, Better, Best Chart has what has never been done and isn't possible with about 12 Million SD IRDs in service.
HD Net Awsome tonight!

And to add insult to injury in the CRT-RP world, most retails seem to have declared them obsolete and maybe carry one or two models (if any).
Makes good business sense i guess - they can stock two or three LCD or Plasma's in the warehouse in the same space it takes to store one CRT-RP, and they sell the LCD/Plasma's for two or three times the price.
Glad I bought mine when I did - they're getting hard to come by!
Whenever I'm in best buy I check out the $3000 LCD's and Plasma's, and I still think the CRT-RP that I paid $1000 has a way better picture.
In my opinion, CRT-RP is being killed off before a viable technology with better PQ has been made available. Damn shame!

I said that exact thing back in post 22, but it was ignored (about not being able to mix).
And to be correct, there is a handful of E* SD IRD's that support 8PSK, but I am guessing those models dont make up a large percentage of the overall SD IRD numbers out there. (models 111, 311, 522 and I think 1 or 2 others).

Yep. Attached file shows statistics from a capture taken within the last hour on HDNet. 1440x1080i, like all of my recent recordings of HDNet.

My local NBC station is sending out some of the prime time dramas at some of the highest bitrates I've ever seen. Tonight "Las Vegas" was hair above 17.0 Mbits/sec, resulting in a file over 8,000,000,000 bytes (63 minutes recorded).
Somebody correct me if I'm wrong, but I don't think you measure CRT's in resolution the same way you do digital displays. Here is the chart in my RCA RP CRT:
SD HD
525 1125 Total Scan lines
480 1080 Effective Scan lines
4:3 16:9 Aspect Ratio
720 x 480 1920 x 1080 Max Resolution
2-ch stereo 5.1 ch Surround Sound
oops, posted before I read the rest of the thread!!!
I guess scan lines are something equivalent to resolution?
I love the PQ from my RP CRT, colors and blacks are great. It is a cheap set, so the sharpness of the picture doesn't come nearly as close to a digital set as it should. Convergence is also an issue. I can't complain for $600.

I know the feeling
You are correct - I should have said the large majority of E* SD IRDs do not support 8PSK and

Yes, but that still is not 26Mps from OTA ATSC that TSReader is showing in the links above.
My CRT RP TV is 1080i and my CRT projector will do 1080p. Judging by the picture on the HDNET test pattern that's what they do.
There must be something off, 19+mbps is all there is available for the 6mhz bandwidth on ATSC channels. Possible talking apples and oranges here.

I was only trying to point out a bitrate of 14.5-16Mbps is enough for 1920x1080i and used the clip as an example.
----Close Encounters----
MPEG Video: Bitrate 65.000 Mbps Resolution 1440 x 1080i
MPEG Video: Framerate 29.97 fps Aspect Ratio 16:9 Chroma Format 4:2:0
shows a bitrate 12.5Mbps.
I read several times about hdnmv was 15-16Mbs at 1440x1080, that did make sense (to me) but 12.5Mbps hdnmv at 1440x1080 does.
Tandberg EN8000 Encoder

Looks like dish has 6 hd on one tp, rummor is Tandberg EN8000
9425 - ESPN2 HD
9426 - NFL HD
9429 - National Geographic HD
9435 - StarzHD
9461 - HGTV HD
9462 - Food HD
Unique combination for HD and SD MPEG-4 AVC single and multi-channel encoding and transcoding
DVB-S2 and QPSK – can fit more than 6 channels of full-resolution HD
DVB-S2 and 8PSK – can fit more than 8 channels of full-resolution HD

Close Encounters 1440x1080 at 12.58 Mbps (Calculated multiplex rate: 12988529 bps) has a peak bitrate of 22.8Mbps. A 26Mbps VBR biterate would indeed be nice.

It max limit; BTW you quoted DVB-S2 from Tandberg - Dish doesn't have support of it. Only DirecTV use DVB-S2 in latest H20 and HR20 ( not sure about D12).
Congrats - you have just listed 6 HD Channels on a transponder - again, not a mix of SD and HD channels on the same transponder which again is what I stated so again you have yet to prove any different then what I have stated when I asked you to give us examples of where Dish has mixed SD and HD channels on the same transponder.
And you have proven again why TSREADER is faulty and gives high readings as the video is set in stone at 17.57Mbps CBR on their distribution.
Once again, this was choosen so HDNET and HDNET Movies would fit on 1 38.81 256QAM.
2 22Mbps channels will not fit.
It’s a little more complicated then that. Multiple MPEG-2 video streams from broadcasters are compressed at a variable bit rates (VBR) and these are multiplexed onto a single constant bit rate (CBR) stream. Statistical Multiplexing is a method of making the most efficient use of the bandwidth available for a given transponder, whilst maintaining a quality of service across all of the multiplexed channels. CBR stream with multiple MPEG VBR payload.
Never said it would. The clip 'Close Encounters of the Third Kind' from hdnmv viewed from a BitRate Viewer had a VBR peak of 22Mbps (very few frames of less than .1% of total length).

great - however there is a hard limit on HDNET and its not even in the 20s for 1 frame as I have tried to tell you.
HDNET uses the same bitrate for every frame in distribution - regardless of what it really contains.
That is why so many titles do not look as good as they should at 17.57Mbps.
If I record a cassette on a DVD, it will have take the full DVD Bitrate - but still sound like a cassette.
