Well it looks like the C-Band Subscription service is over. Been reading all over the net that Comcast HITS will be transferring 70% of SD Channels to DVB-S2. Looks like this will start the second quarter of 2013. GOODBYE 4DTV. Not like we didn't know this was going to happen!

Good thing I sold my units while they were still bringing good money!

Anyone here able to see 127w CBAND? They use DVB-S2/digicipher. I assume that means its the DVB-S2 modulation with the digicipher encryption. 

I wonder if thats what they'll switch to, now will it be fixed key or zero key, or totally locked down. 

My skywalker isnt running right now and havent had a chance todo the tests genpix asked me todo before sending it to him, so I dont even know if HITS is currently using ZK or FK. I dont own any actual DGII receivers.

What I find most interesting in the press release is they will be using some pretty amazing technology.. 

"The upgrade begins in the second quarter of 2013. When it concludes, over 70% of the HITS Quantum multiplexes will be using 256 QAM DVB-S2 technology."

256QAM.. I can't even imagine what sort of C/N that would be necessary to properly decode that.. 

(Please note my sarcasm.  I guess no engineer proof read the press release.. )

I wonder if this will include Shaw Direct ?

What about those DC 2 signals on M6 & M5 ?

Equipment Needed
If you take signals only from the 64 QAM platform after the upgrade, you DO NOT need to purchase
any new equipment. HITS is maintaining the highly penetrated 64 QAM multiplexes.
NAS/Local Control Systems - If you take the upgraded 256 QAM services, you ONLY need ONE
Motorola DSR 4410MD to receive 2 multiplexes. The DSR 4410MD allows you to receive 2 multiplexes,
from one transponder, using a single receiver.
QT/QT+ Systems - If you take the upgraded 256 QAM services, you ONLY need ONE Drake 2x4 to
receive 4 multiplexes. The Drake 2x4 allows you to receive 2 transponders, with 2 multiplexes on each,
using a single piece of equipment.
All HITS Services can be received from a single satellite. HITS signals for all multiplexes will be available
on AMC-18, thereby minimizing the number of dishes needed.

All my sarcasm aside:

I am sure when Comcast references a 256QAM DVB-S2 Transponder they actually mean a DVB-S2 30000 8PSK 5/6 FEC Transponder.  
I am sure when they reference a 64QAM Transponder they actually mean a DCII 19.51 3/4 FEC Transponder.

If you look at CWDM's posts (I assume from the horses mouth) it says you get 2 multiplexes per transponder with the new system.. In this case multiplex would mean 6mhz wide cable channel.. 

Doing a little math it all makes perfect sense.
The DVB-S2 8PSK transponder has a bitrate of approximately 74mbit.  The bitrate of a 256QAM Cable channel in NA is 38.8mbit. (2:1 ratio)
The DCII transponders they use now have a bitrate of 26.97.  The bitrate of a 64QAM Cable Channel in NA is 26.97mbit as well. (1:1 ratio)

http://cdn.rohde-schwarz.com/dl_downloads/dl_common_library/dl_news_from_rs/article_6_7/n172_efa.pdf <-- If you want to see NA Cable Data Rates I found them here.

That may not answer the question as to if the 5 remaining DCII QPSK modulated TPs will be available for direct consumer purchase, but it sure doesn't look like the DCII Boxes will be entirely obsoleted with this change; Especially since its' only Comcast upgrading. Not the other slew of companies with DCII equipment in use.

I would guess that this is all in reference to the fact their main customer base is cable companies. satellite ird w/asi -> cable qam modulator. 

There is talk on other boards that they will switch over entirely to PowerVu. Who knows though, lots of speculation not alot of facts. We'll just have to wait and see I think.

If all channels will be available on AMC 18, does that mean they will be terminating their DCII combo mode muxes on SES 1?

The 256 QAM has to be refering to the cable end of things, no way they are going to use QAM256 for satellite. I cant even imagine the requirements for that to be half reliable.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
