picture quality

I have just changed out 4 x 6000's for Bell supplied 6141's and the customer and I noticed no difference between picture quality or brightness. 2 TV's were connected with Component and 2 using HDMI.

I believe BrystonUser has a defective box.
 
I've not heard of the announcement. Bell must have thousands of 6100s and 9200s in the field they would have to swap out. And considering they were about 6 years behind Dishnet switching to 8PSK, I wouldn't hold my breath.
 
How come HD Spiderman 2 on my Bell Showcase HD today does not look as good as Spiderman 2 on my DVD?
 
So my question is, are any of the "HD" American Superstations going to be converted to 8PSK?
 
I personally use component,, I first tried HDMI with my 9242,, my setup is everything plugs to amp to tv,, i did notice hdmi connection colors seemed alot brighter and washed out,, component blacks were blacker, picture seemed slightly softer too.. i run my blu ray hdmi,, its flawless..
 
Also, to get them to stop saying "the most HD channels" and "more then 100 HD channels (true only if you count the french ones)". I would also like them to stop advertising the HD offerings on SpeedTV SD, like we can get that in HD!

bah they should just switch to mpeg4 and 8psk at the same time and they have tons of room.too bad its financially impossible to switch the SD channels to MPEG4 too
 
Yes, both those machines are MPEG4 capable. When it will be implemented is any body's guess. It is the older model 9200 that is not MPEG4 that is holding up the transition to MPEG4 because Bell would have to offer those customers a deal on a new MPEG4 PVR. Bell is waiting for as many of them to die (so they don't have to replace them) before they do the switchover.
 
The evidence comes from previous threads (and this thread) where people have connected HTPCs to monitor format and bitrate. We know the bitrate of the transponders too and know that there are typically 3 channels per 30 Mbps transponder. See the format link and the threads discussing format and bitrate in post 272. All you need to do is check out the previous threads on this topic.

The resulting PQ can still be quite good, however, the format change and compression can affect some programming more than others.
 
I do not have any artifact issues with my TV's (I have 3 HD TV's, all set to 720p). I watch hockey, football, car racing with no issues.
 
So if nobody else sees these artifacts (not digital artifacts but just a blocky picture in dark background, and blocky is the wrong word to use), then what could be causing this for me? Like I said, I see it on both my HD and SD tv, I have a Pioneer 6010 1080p plasma, and had a Panasonic plasma before this one that also displayed these, so it's not the tv as I've seen it on more then one and other sources don't show it. So what can it be, I've tried different HDMI cables, all come with the same result, I've went from a 6100 to 9242 receiver, same thing. Could it be something wrong with my LNB's or dish in general?
 
Interceptor: I agree with you about Centre Ice on Bell last night. Picture was great on all four HD channels. There was an early game lighting issue in Edmonton but once that was out of the way the picture looked great. My TV by the way is a Sony SXRD A2000 60 incher by the way.

I too have suggested that the problems may be set or set up related or perhaps even related to geography/satellite angles/atmospheric conditions. Unfortunately the experts seem to dismiss these factors.

What I'd like to see is a blind viewing test to see if some of these problems are real or just subjective. Unfortunately I don't have the resources or facilities to make such tests a reality.
 
I too sometimes wonder if the poor quality on some channels is because of location, it's not one person in one place that's for sure as I can see some bad quality on my tv (Pioneer 60" Elite), go to Vision's or Future Shop, find the same thing on Bell and see the same problems in the quality, so it's not just me. I wondered if the Centre Ice channel of the Flames/Oilers would look better, the Sportsnet channel looked really bad, of course to me all Sportsnet HD channels look bad including the full time ones with the baseball on last night. However, the early games on Centre Ice I found the quality to be quite good. Watched the Ducks/Bruins game and the quality was really good. Sens game didn't have any blocking either, but looked soft to me. I also notice some macroblocking on CBC Montreal on HNIC, but when watching on CBC Toronto the picture is really nice, except game two last weekend almost looked like SD Widescreen to me. I notice the same with TSN, noise and blocking in the picture, but watch the same game on TSN2 3 hours later and it's quite clean, way better then TSNHD. So you can try to explain that.
 
I watched the Canadiens / Buffalo game on Saturday night on CBCHE and was it just my setup or was it really bad ? The blurriness was awful and there was jagged lines in many places. Compression artifacts galore. It usually is OK but I have not Hockey broadcasts from the Bell Centre look this bad in a while. Anybody else notice this ?
 
I'd imagine for workflow reasons...

The signal that Bell gets is much higher bitrate than they transmit.
After switching encoders (from essentially CBR to VBR) and going three hidef channels per transponder, I think Bell wants to keep control over bitrate allotment per channel. This can't be automated, at least not yet... Therefore, it must be done manually on case by case basis.

The footage provider, being it network or movie channel, might also insist on not having hard copies of the material provided (just a guess on my part)...
 
Please don't take this the wrong way but I sometimes wonder if those of you with PQ complaints ever watch a station/program for the content?
 
What was up with the Penquins game last night ?

Was it the cameras they use in the bulilding.

The Vancouver game looked good.
