BCE Sells Telesat; New BEV Nimiq 5 to be at 72.5!

Yes; on the other hand isn't it true that both satellites at 82 (prime and backup) are on their last legs to be replaced by a satellite launch in 2008? satellites typically have a 10-12 year shelf-life.

There was timing for this satellite launch but given the lead tmies it sounds like this is perhaps 2010? An *awful* lot of changes could have been wrought in the consumer TV provider market by that time. I wouldn't care to speculate on who will still be a player four years from now.
 
Wow...this sounds like a massive undertaking for Bell. Instead of moving the dishes, I think they are going to have to put another dish with the 9 degrees of the other two or they are going to have a lot of people without service. So that wouldn't be a possible solution.
 
Ciel satellite Group posted this related report which I posted earlier. I can only assume they are interested in providing services for Bell and Starchoice. I don't know how exactly that would work though. I think that sharing of services is the only practical solution to capacity problems for the satellite companies. Many technical challenges though.

If Ciel's prediction is correct, by 2010 BEV would need: 100*7Mbps + 382*2.2Mbps = 1540Mbps bandwidth.
With 27Mbps per transponder (number Ciel is using, probably due to overhead) it boils down to 57 transponders.
Adding some inefficiency of bandwidth utilization would probably bring it up to 60 or so, i.e. two fully functional sats.

So, theoretically speaking, Nimiq 4 and 5 could do it with the current sats in standby.
But by 2020 (again, if we believe Ciel), BEV's bandwidth requirements double and they would need more birds
(even the not yet launched 4 and 5 would be 10+ years old by then). But thats probably looking to far ahead.

EV is currently using more than 1 sat for SD now. I don't see them switching from MPEG2 for SD anytime in the foreseeable future. They don't have full use of N2 either EV will require another sat for the extra HD alone (70 more channels using 23 transponders @ 3 channels per transponder with MPEG4.) I base that on the fact that EV typically puts only 1 MPEG2 HD channel on each transponder and MPEG4 is at best twice as efficient (space wise) as MPEG2. I doubt that E* receivers will be using the best MPEG4 compression. I'm sure EV will add every available foreign language SD channel (and whatever else they can make a buck from) by 2010 as well. EV could move all HD to 72.5, once N5 is operational. (96 channels @ 3 per transponder.) That would free up N2 fo more SD and reduce the need for dish upgrades. I expect they will keep some HD on N2, maybe just some basic Canadian networks.
 
I'm speculating that the move of DTV 1R has nothing to do with BEV specially since DTV 1 has been at 72.5 (under Telesat control) for quite some time. Also, there's proabbly an agreement in place that Telesat lets DTV use the 72.5 slot for the time being, but they have to fly the satellite in order to satisfy Industry Canada regulations or something like that.

Why hasn't BEV switched to 8PSK for HDTV?? I would assume (and again I'm speculating) that the currently deployed STBs are not capable of demodulating the 8PSK signal. Rather than having to replace all the STBs now and then possibly having to have a bunch of subs repoint their dishes in a couple years when N5 is launched, they'll do it all at once.
 
As Diogen mentioned, BEV doesn't care what happens to the old satellites.

Typically when a satellite has outlived it's useful life for a particular company, they are often just put in a parking orbit until such a time as some buys it a temporary spare or orbital location placeholder such as Telesat has done for the current Nimiq 4i. Once the satellite is deemed no longer useful to anyone, they use the remaining fuel to push it out as far as possible where is simply becomes space junk.

As an aside, Telesat has a very good record for be able to reliably operate satellites well beyond their design life. Anik C1 was in service for over 18 years. Well beyond it's design life of 12 years.
 
I thought the model 6000 receivers had a slot for inserting an 8PSK adapter and I thought the 9200 receiver had it built in ???

I know this to be the case for Dishnetwork.
 
Yes, that's Nimiq4 which, last I heard, is supposed to launch in 2008. It will likely replace one of the existing birds though. Not a new slot.

Nobody is claiming they will.
They will have at least 4 HD channels per trasponder (Ciel, 7Mbps each), maybe more, up to 6 (Telesat).
Typically - two: HDNet & PBSHW, S+HD & VIEHD, EQATR & RUSH, MCHD1 & 2, etc.
And they will double them, cutting the bitrate in half.

You should read those two documents from Telesat and Ciel.

Diogen.
 
Do you know which one?
82 has a bunch of idle (non-working?) transponders.
That was always my understanding.

Diogen.
 
Well geez, you lose the purpose of HD if you downgrade the PQ.

I am not at all in favor of this.

It wouldn't be true HD.

I thought MPEG4 would open up room to give more HD channels, does this mean they cut the PQ on them.

I take quality over quantity any day...
 
Maybe Bell is going to use the Dish 1000, as it can pick up all three obirtial locations. The Dish 1000 antenna is used by Dishnet to receive signals from three orb ital locations: 110
 
I must say, this is an interesting read.....

Question, is it possible to "purchase" orbital space? lol
Maybe if we can start doing that, ppl will make money on leasing it to bell and other companies, lol..
Forget buying land, buy SPACE!

As for all this info, would be nice in a couple years to see everything in HD, Obviously the re-runs of Married with children wont be HD, but hey... :D Ill still watch Peg in HD. lol
 
"I'm sorry to inform you that the Clarke Belt is sold out". :eek:

Seriously though, I've no idea.
Considering each bird gets some 100kmx100km window to drift in, there must be empty slots.

Diogen.
 
Hmmm I know a lots been speculated but hmmm which direction would these new or re aligned satellites be?

I am in Vancouver so my dish faces southeast, forget the actual degrees but I am hoping it would face more south than east.

Thanks

I still have some damn branches that get in the way thus only get anywhere from 65-75 percent on the one sat. :mad:
 
All BEV`s HD stb are capable of demodulating the 8PSK signal, with the exception of the 6000 which has a slot for a 8PSK module as well as a 8VSB module. When Dishnetwork added Discovery you had to upgrade to 8PSK to get it.
