How are your signal strength numbers?
I was thinking the same thing. However, the issue is only during “fast motion” scenes. I thought if your signal was poor, you get “blocking issues” on slow moving scenes too, not just fast.
I guess I could be wrong. Won’t be the first time. :lol:
I hadn't paid attention to the fact that the playback was paused in the picture. Still, often with action, a paused picture will show more blur than the picture during play because the frame that is paused on does contain data from 2 adjacent frames, at least, with a 1080i signal.
From the quality of the image posted, it is hard for me to know for sure what I'm seeing, but it does look there is an issue with pixelization. For that reason, I'd also wonder about the signal strength and wonder if the signal could be going in and out repeatedly. And I would also still be interested in knowing if the OP is seeing the issue with both 720p and 1080i programming or just with 1080i.
Join the club.
"What I think" is happening, is there simply isn't enough bandwidth being allocated "fast enough" for that program.
Each transponder carries about 5 HD channels. During the uplink process and the transcoding to MPEG-4, there is also a process that "guesses" the bandwidth needed and tries to figure out how much the other channels "aren't using" at that moment.
It looks like "the guess" wasn't correct.
DirecTV does this to maximize their bandwidth and not have any wasted. It's fairly complex, but if one channel doesn't need it at a moment in time, it is better to allow another to use it if it needs to.
Not sure if you remember the PBS Ken Burns Nation parks series a while back, but it ate up the bandwidth like no other program. Mine came off a OTA feed to DirecTV, that was a 720p and couldn't have used most than 19 Mb/s, yet recorded in MPEG-4 @ greater than 20 Mb/s, which cause it to take up twice the space on the DVR.
Prime time airing would also breakup so bad you couldn't watch them, but the late night airings came in fine, since all the other HD channels on the transponder had gone to low bit rate programing.
If you search [or remember] there were many posts/threads complaining about Ken Burns back when it aired.
That is crazy stuff. I didn't know there was a process like that.
It sure is.
We're long past simply wiggling the rabbit ears to get a better picture. :lol:
VOS knows his stuff as he is an Undercover Agent for DIRECTV!!!
Saw your pictures. I have six Panny plasmas and have bought seven. One went bad, made noises and I returned it to Costco, got my money back and promptly went to a 6th Avenue store and got the same model for about $200 less and have never had a problem with it.
I've called Sony and Panasonic several times and have found out that they don't really want to talk about the TV sets that Costco sells. I'd take that plasma back and get a new one somewhere else. Try Vann's in Montana. Free shipping and if it doesn't work right, free shipping back. And really low prices. The model you got is a highly recommended model and should have no problems.
I called Sony several times about a model Costco was selling. It looked like an 800 but was called an 801. Sony didn't want to talk about it, and I finally got a CSR at Sony that would. His advice, in a nutshell, was buy your TVs somewhere else.
The Sony that I was looking at was a 60" 240 Hertz LCD, with LED backlighting. Since discontinued. Asked the guy what the difference was between an 800 and an 801 and he told me to take a ride and find an 800 of any size and compare them.
I found a 52" model in a BB and I quickly saw what he meant. The salesman I talked to was familiar with the 801s that were only sold thru Costco and Sam's Club and showed me many features that the 800s have that the 801s don't have.
But you're having the same problems on both an LCD and a Plasma. And your pictures look like pixellation problems. That happens. Not much you can do about that.
It's no real secret that the mega-retailers (Walmart/Sam's Club and Costco) often order special versions of existing products with fewer features that can be offered at a lower price. These will have their own model numbers that you won't find on the manufacturer's website, for example. They can be a good deal if you are price-conscious more than you are picky about picture quality and/or features, but if you want the "real deal", you need to get the real thing.
EXACTLY!!! For awhile Sams was selling ED TVs (480P) as HD Sets and most people didn't know the difference because it was a Widescreen TV. People just don't know technologically what the difference is or what Bells and Whistles they need or don't need.
At least someone someplace in the food chain has the decency to put odd numbers on the models that are sold in the warehouse stores. That Sony that I was talking about cost $3000 six months ago and they are still sitting there on Costco's floor. Now they are selling them for the same price but adding a 3D BD player to the package. The TV is not a 3D set.
The guy across the street bought one of them for a hefty price and paid a premium price for an extended warranty. When he showed it to me I told him it wasn't an HD set and he got extremely angry. Asked me how it couldn't be HD because it was in 16:9 mode. Asked him if he hadn't noticed everyone had a pumpkin sized face. He finally got a Panny Viera Plasma. Some people are so dumb, it makes you wonder how they exist.
Directv is broadcasting in "half" HD :lol:
I've been told that Sony uses the same technology that Panasonic uses and that explains why the Sony's have the best LCD PQ. Don't know whether the guy (at Vann's) was right or not, but the Sony LCDs I've seen are much better than other LCDs. I think.
Sony uses a different panel, that is also used by 2-3 others in a joint development agreement. One of the features is better blacks than other LCD panels.
To be fair though even HD sets commonly do that, display a horizontally stretched picture if the TV is set to wide mode while receiving a 4:3 signal anyway.
Or do you mean that the sorts of ED sets like what Sam's Club formally sold may receive an actual 16:9 HD signal off air or something, but will then down-rez it to 480P resolution and crop the image to 4:3, which in turn naturally causes a stretched image to 16:9 if the TV is set to wide mode?
I thought what a wide screen ED set does (or maybe "did" I guess) is similar to what a DTV converter box does today when receiving an HD off-air signal and set to 16:9 mode. Will down-rez or "convert" it to a 16:9 480 line vertical resolution SD signal, but 480P for display on the EDTV and 480i for the output of the DTV converter?
Therefore the only way to really tell the difference between HD and ED is the higher sharpness in PQ, where ED looks about the same or less than that of a standard definition wide screen (or anamorphic) DVD in comparison.
The guy I talked to at Vann's did say that the Sony would produce the same blacks as the Panny plasmas do. Couldn't really follow him, too techy for me. Got the gist of it, tho.
His Phillips plasma definitely was not an HD set. He even brought out the manual and I showed him where he made the mistake. When we set the thing to a proper setting it showed a better picture, not the pumpkin head pictures. He's one of those guys who believes salesmen. His was very much like your description of the EDTV or SDTV. Just a stretched SD picture. He got suckered into that one. And naturally took out his anger on me.
Oh I have no doubt that it was not an HD set, and your neighbor indeed got snookered by the proverbial fast-talking salesman for sure. I was just pointing out though that you really can't tell the difference between a 16:9 EDTV or HDTV set based solely on the fact that the picture is stretched ("pumpkin heads") in wide mode, but on their respective PQs which is where the real difference lies.
Unless you are looking at the specs as you did of course ...
Yeah, I got that. As soon as I saw the picture and the station it was on I knew he had made a big mistake. Proving it to him was the big problem. He had had his downstairs remodeled to make it an entertainment room and didn't want to admit that he had done something wrong. Never does. He even put a wood floor down and that was below ground level. I kinda doubt that many manufacturers of wooden flooring recommend putting them down below grade. Nice room, really crappy TV. He finally took a walk across the street to my house and watched the same station on one of my plasmas and finally saw his error. It never ceases to amaze me what people do.
