    The data being read does not differentiate between SD and HD... only MPEG2 and MPEG4. WHAM-DT2 is now being simulcast in MPEG4, but there is no reason to believe it will be available in HD anytime soon. Perhaps you'll see the channel in HD a few months after DirecTV and Sinclair renegotiate.

    I feel your pain. My local affiliate of The CW (WSWG-DT3) started broadcasting HD OTA in October of 2013, but it's still SD on DirecTV.

    Yes, this past week helped reassure that our understandings are valid. They put the apples in the apple box and the oranges in the oranges box.

    Initially in PR, both CONUS+ National Redirects and Local PR channels were both provided by D14 Network 10, 99CA resources. Then this past week, they segregated the CONUS+ channels on 99CA and the PR Locals on 99S. The pieces all fit once again. The "Network 10, 99CA" and "Network 11, 99S" notations are valid indicators of the channel source.

    I have a feeling part of the reason its taking time to do all this is because they are not in a big rush, since they are probably strictly in rearrange mode till d15 is up and working, and the more sats you have you have up there, and the more complex they are, the more complicated moving stuff around becomes I'd imagine...

    I just did a quick spot check, those channels I posted back in post 848 are now coming from D14!

    The odd/even test channels are also now live on 9504 and 9505

    stoutman,

    In recognition of your frustration, You are the first, and at this time the only, DMA to have your MPEG-4/SD-Content channel properly marked in Green Shading in the TPN Map, beginning with the next posting. There are many other DMAs with your situation, but only yours will now be properly marked.

    We have this same condition in the CONUS tab - a number of SD Content channels are provided via MPEG4 compression. Our identification of these channels with Green Shading is only a sampling because it is a manual process, not a part of the weekly data collection.

    So does that mean that the other satellites are now showing empty transponders that were once occupied by those channels that are now on D14?

    Not whole xpndrs, but like vacated time slots on other xpndrs they use to share. So a former xpndr that use to have say 6 channels may now have 5 or something for example.

    Correct, I meant slots. Thanks.

    We won't know what's on the previous transponders until Gary and Doctor J do a new map.

    He seemed to think he had discovered significant changes that had come about with D14. I'm sorry it took us two days to respond. Turns out KyL416 was right. Very right. Big time.

    Doctor J did a data capture about 1:00 pm (PST) today. I will publish that 150427 TPN Map in a few minutes.

    Neither Doctor J or I did any real analysis; we will do that on our usual Wednesday post. But you folks do some darned good analysis on your own, I'm not sure you need us. So here is the data, two days early:

    D14 is now providing some 61 LIL channels via Network 11, 99S for Local Channels and via Network 10, 99CA for Puerto Rico mirrored nationals.

    But KyL416's astute discovery over the weekend was that D14, since our last TPN Map, is now providing 31 CONUS channels via Network 10, 99CA for the US Domestic market. THAT is a significant corner that we just turned.

    I will stop chatting and just post the data so YOU can begin some analysis....

    If you look at what SW1 & SW2 are currently covering versus available spots on D14, at least half the DMAs will go away from the Spaceways. Leaving plenty of room to add those uncovered DMAs. Possibly enough to allow retiring one of the Spaceways, hard to tell.

    16 is in the 90s again. 14 is still 0

    I have participated in a lot of speculation about what is going on with the satellites in the past few months. I had a hard time getting my mind around TPNs, TID, Frequency, and licensed spectrum utilization. I have gone off and pulled in every technical resource I could get my hands on, verified it all against Gary and Doctor J's transponder maps, and came up with a documentation of the DirecTV spectrum, correlating TID, TPNs and frequency. In 3 simple Excel spreadsheet pages, you see a lot of what's going on, as well as what could or could not happen in the future.

    The spreadsheet is here: http://www.dbstalk.com/topic/216777-tech-reference-library/#entry3357015

    In the course of this, I discovered some of the mystery of why the D14 spotbeams are using the TID and TPN numbers they are: Because they are on the same Net number as SW2, they cannot have a TID that duplicates a TID on the same NET on SW2. The TID's they chose for D14 spotbeams are the lowest block of unused TID's on a SW satellite.

    Wow Tom, nice work! It's a great visualization to see how it fits together.

    +1 here as well;

    Yes, nice work indeed Tom;

    Just a few notes though :)

    1) The last total outage of D10 revealed that all LiL spotbeams at 103W are coming from the Ka-lo band spotbeam payload of D12 not D10 even though their two SB payloads are identical.

    2) You show all LiL spotbeams at 101W as coming from the old D4S. Do you know this for a fact somehow? Last I was aware of it's not known on our end which local spotbeams are coming from the SB payloads of D4S or D9S as their local TID ranges overlap.

    3) You show TID numbers 20, 21, 23, 25, 26, and 29 for D7S at 119 grayed-out as though not assigned to carry programming. Yet the TPN maps show all these except for #20 carrying programs (And since there is no xpndr 21 where does TID #20 come from anyhow?).

    4) The tail end of the TID listings for D14's CONUS beam xpndrs should read as a grayed-out 20 and 22 since xpndrs 21 and 23 are defined and 22 and 24 undefined as N/A.

    You pose some interesting questions. I did the graying out of the TIDs as a last minute thing yesterday from Gary's TPN maps. I rushed trough the Ku band stuff and I may have got it wrong. I will review that later this evening.

    As for the other items, I will go back and review the sources of that information and how certain we are of the accuracy, and let you know what I find. Unfortunately, I will not be able to work on this until later this evening (Eastern time). If revisions or footnotes are needed, I will post the changes..

    I didn't spend a lot of time on the Ku stuff, so it is more likely to be inaccurate. I was primarily focusing on Ka bands.

    I'm still confused by the TID stuff and spotbeams, but you've quite accurately condensed my confusion onto a single page :)
