8PSK Conversion

I just checked lyngsat and there is 27 tps with HD signals. Some of those carry SD signals though. I don't think they can switch to 8PSK in this case since those SD channels would not be accessible with regular SD decoders.
 
If anything launches, I can see it being CNN (maybe), CBC Newsworld, Golf, and possibly Speed. Hopefully those will be all and they will increase pq. I don't want to see the Omni's in HD, SunTV, or E. Last thing we need is more simsubs.

I can also see Sportsnet East and West get turned on to full time HD channels, not just for games.

I'd also like to see CTV, CBC, HDNet, NBC, CBS, PBS, WGN, TSN and what ever other HD channels they have get converted back to 1080i instead of the 720p we are getting on everything now. It does make a difference.
 
Anyone have any information about how the testing is going...and a possible date to go live?
 
Arent 3100, 4100, 5x00 all capable of 8psk?? 2x00, 3x00 and 4x00 probably arent,, and who knows how many are still in service.
 
I forgot about this thread, it has been so long. To my knowledge Bell has not implemented this modulation scheme. Technical experts at "satelliteguys" say this is not a difficult process at all. I don't know what the rush was to clear out all those 6000 receivers in such a clumsy and logistically stupid way! However, Mike says that things might change tomorrow with new HD channels coming on. I guess will have to wait and see.

Consider that you are only as good as you're weakest link. Picture quality is affected all the way along the stream which starts from the source.

Newer programs such as the Merlin will employ the latest HD acquistion equipment during the production phase. With every fiscal period that passes more and more production facilities and broadcasters purchase newer and better HD equipment, including but not limited to expressvu.

Regarding the MLB poor quality post, it is also fair to consider some of the sports production facilities are still using first generation HD equipment as sports programming was one of the first to convert. Some made the conversion into low end equipment by financial limitation but with a desire to say they were HD. Their image may seem poor in comparison now.

As the days and weeks and months progress I'm sure the quality will continue to improve however you'll still be dissappointed every once in a while.

Many factors to consider when evaluating pq.
 
crazycanuck, it's not just you. I too feel that the PQ is better. More stable than before. Very noticeable on TSN/CFL football.
 
Right, but I don't think anyone is going to switch providers for those few channels. But back on topic, I think Bell's picture quality is what it is and I expect most other providers, particularly those that don't yet offer as many HD channels, to soon follow suit.

I believe they're in the testing phase still. TP05 is the only 8PSK transponder so far. That said, I haven't noticed any change in video quality.

Bell just added a 5th channel in the 8PSK test transponder (#5). So that is 5 channels in all.
 
Is it the conversion to 720P that is causing the soft picture on most HD channels, or is it the over compression of the signal? TSN HD looks great most of the time, as does SN HD and CBC HNIC HD. Are all of these channels originally broadcast in 720P so that no conversion is needed?
 
i kinda hope they don't add to many more ch. and just reduce the compression on what we do have.
 
Interesting point about low end equipment. I think a lot of people who complain about bad HD PQ don't realize that HD gear is not all the same. Just as consumer units vary in quality so do professional components. The poor pictures we complain about here and for which we blame our suppliers may actually be caused in some instances by the equipment used by the broadcaster.
 
Exactly the Module was NEVER offered by Bell as it is NOT in the software for the Bell 6000.
 
Conversion pretty much complete. All but 5 transponders now.

TP - 1,2,6,15 & 16 are still on the old tech
TP - 3,4,5,7,8,9,10,11,12,13,14,17-32 are 8PSK now.
 
Not to burst anyone's bubble, but 8PSK MPEG2 really only allows for 3 channels per transponder. I say "allows", but what I mean is that 3 in 8PSK yields roughly the same PQ are 2 in QPSK.
Now obviously Bell is moving to 8PSK so they can increase the number of channels, so don't hope for an increase in PQ. It's not realistic.
 
How many ae there currently per transponder 3?

if they go with 4 will this make PQ worse or better, or same?
