From Sixto posted on locked thread:



Sixto, shouldn't the selected mix channel 9702 be on D10 Tp. 14 based on previous postings?


Those *DTV channels seem to be what are now test channels which were formally the US Open "placeholders" in Sixto's previous post #1466 on the locked parent thread.

http://www.dbstalk.c...684#post3033684

That's why I questioned if D10 transponder "10" was accurate for channel 9702 and shouldn't it be Tp. 14.

Sorry, was out most of today ...

The simple answer is that 702 moved in the interim.

It was in an offline state ("1700") on one transponder and it moved to another transponder (still in an offline state). I don't show when part-time channels move from "1700" on one transponder to another, since they're not using any bandwidth.

Also, the 97xx channels always mirror the 7xx channels for these special events, always been that way. It will be easier to see now that the thread is locked and only the updates will show.

A while back I needed to decide what to show and what not to show, along with comments from others as to what folks thought was important. Decided to never show 1700 to 1700 moves. Lately I also usually don't show when they turn part-time channels on and off, because it clutters up the data, and there's usually very little of it in the morning anyway, unless it's long term part-time channels like the 7xx channels.

One other thing ... I do have a slight bug in the data presently where I'm not always getting these "redirected" channels correct. It's not a big deal because this analysis is mostly just to track channel addition or subtraction, but I would like to have the maps 100% accurate. Currently, I'm manually fixing the redirected channels until I nail the position of the redirected flag. Had PM'ed gct recently, may need to reach out to P.

Isn't that the truth. Sometimes just don't know why, it just is.

You guys do the hard work, every channel on every transponder. When I embarked on this solo mission, it was just to try to notice daily if any HD got added, and I've been tweaking it ever since that day a few years ago, but again you guys have the first-class tools and data.

Do you guys use DVB-S2 PCI tuner cards or are you getting it via serial from a directv set top box?

I recall someone asked the question with an intention to get his hands dirty ... year ago ... ;)

Cheaper solution would be using USB-Serial dongle and pull the data from your DVR/receiver. $15 total for the dongle cable.

More expensive is using sat feeds and PCI/PCIe or USB sat tuner.
The card could be cheap TH1020A (with DSS support) or first-class Genpix SW-1/2. Only newest SW-3 would support DVB-S2, but it will add only Ka PIDs bitrates measures - all system tables are on Ku [101W, etc] sats.

D12 doesn't start at TP1. It's actually 44 total, but D12 TP20-24 have always been used for other purposes, thus it's more like 39.


Checked the tpns:
  • 20,21 - empty, no channels;
  • 22 - has 6 channels(1800/10/20/30/40/50);
  • 23 - 5 channels (1800/10/20/40/50) and 7 Mbps reserve for 1830
  • 24 - 3 channel (1800 ...)

Well, if you'll watch the tpns long enough you could see the PIDs comes and go ... perhaps the PID range is telling : PUSH channels are here.

My focus has always been to just look at national HD daily. You guys do an excellent job of covering the full scope.

You have the tools, the reports, the expertise, and all the cool stuff. I just decided one day, several years ago, to wonder how national HD is delivered, and to analyze daily how they manage the bandwidth.

I guess Sixto intends to include the MPEG-4 SD channels as a related side statistic since they share the same transponder MPTS with the HD channels.

I think its because D10 was the first to offer national HD programming on the Ka band, and lately due to its well publicized technical problems and attempted fixes.

And D12 because of it being the first to offer national HD from an unprecedented 16 CONUS transponders on the Ka-hi band as well as its spot-beamed RB-2A RDBS payload which has drawn a lot of interest and speculation as well.

So TCM is looking like another 6th channel, and right after the quarter turn?

What is a '6th channel'? 6th channel on a single transponder?

Any idea how long until TCM HD is actually live and on the air for viewers?

Yes, under the previous standard DIRECTV would assign no more than 5 HD channels per Ka-Band transponder at 99 or 103W.

However with the installation of newer encoders DIRECTV is now transitioning to a customary transponder loading of 6 maximum per Ka Band Tp..

... Any idea how long until TCM HD is actually live and on the air for viewers?


New channel launch dates are usually on an early Wednesday morning at 6AM EST this week or any following one.

Yes, 6th channel HD channel on a transponder, same as some of the recent additions, with the assumed new encoders.

No idea of timetable, but probably in July.

Maybe I missed it, but you have any data on if six is the limit now? That is, any way of telling how much space is actually there with the assumed new encoders?

Per the paper that we found, it said a 20-25% reduction. Assuming 8Mbps previously, it now could be closer to 6Mbps.

There's actually now one transponder with 6 HD and 1 SD on D12.

I was also reading about H.265 this weekend, it will be even better some day, way in the future.
