Am I the ONLY ONE who sees pixelation in almost all HD televsions?
I don't see it on blu-ray but from a cable or satellite "hd" source no matter where I am, what the tv is, or whatever else, I see the pixelation. It's huge and disgusting and ugly. No one else can see it or will admit to it being there. What the hell is going on with that ?

You need to clean your glasses?
|
Try sitting a couple of feet away from the TV at least.

I do a lot of development for set-top-boxes/connected televisions and have noticed a bit of noise with some hardware.
Now, notice that I said "noise" rather than pixelation. Many times, noise can be reduced by using higher quality cables. Things such as EMI/EFI can cause issues as well. If you aren't noticing it on your Blue Ray, perhaps it's because the quality coming into the TV is better than what is over your digital cable. If you're using digital cable, the quality can be lacking if the bandwidth is shared with your Internet connection. |
Are you drinkin again Maxwell?!? :(

cable tv is compressed and will give a crappier picture than a blueray or over the air tv signal.
|
Clean the dried cum off your glasses.

Your cable broadcasts are probably 720p, whereas Blu-ray is 1080p with a much higher bitrate. But you shouldn't see any pixelation with 720p, at least not from a normal watching distance.

I agree. It's hard to find a very clean looking HD picture, even when using BD and optimal settings. A lot depends on the original source quality. If you're interested, Planet Earth has the best picture on BD that I've seen so far
|
It's the compression. The busier the image, the worse it is.
|
only if the connection thats relaying the signal sucks should you see that.
at least thats my two cents whether it be right or wrong ;) |

I see it much more on LCD TV's.

yea, you can see it pretty clearly (if you know what to look for), but compression artifacts is probably better way of describing it than pixelation...

Yeah. Compression artifacts. Very similar to a movie that's been converted to a different format a couple of times. |

Its the Source Not the TV |

1080p sends twelve times as many pixels per second as 720p, but the satellite providers only allocate three times as much bandwidth. Therefore, they compress the hell out of it. They already compress the standard definition also, so when you're done the compressed HD content actually has about the same quality as standard uncompressed analog SD. Old fashioned analog TV is a 6Mbps signal. Satellite HD is about 9 Mbps trying to carry twelve times as many pixels. |
That must be it, because I notice it on 1080 and 720
Why the hell do television stores use cable/satellite sources? That is really stupid, I think. |

BluRay streams to your TV set via HDMI at 40 Megabits per second. It is 1080p lines of crispy, sexy goodness with virtually no "pixelation" or color banding (Color too, needs lots of bandwidth to have all of them displayed). "HD" content provided by cable and Satelite is compressed like crazy resulting in a shitty image no matter how good your TV is, and broadcast at only about 3.5 Megabits per second. Why so low? Because bandwidth is expensive. On top of that, no channels broadcast 1080p or even 1080i. It is all 720p. |
Why is bandwidth expensive for cable providers? Is it because they still use copper for quite a bit of their network and are pretty limited?
What about satellite providers? Do they have to have more transponders or whatever they are on the satellites themselves for more bandwidth? The very interesting question is: With 100mb+ in home connections these days, why is there no true 1080 option? I know the bandwidth would cost a lot but they could kill selling movies for half the box price on pay per download basis |
only when i watch TV on my 10,000" screen

You're not the only one...

Satellite channels pay for bandwidth all the way through the chain. From their Studios to the uplink provider and then transponder bandwidth. Wherever they can squeeze a few thousand bucks out of carriage charges they will, you can change bandwidth by the hour and save more money depending on what your schedule is so plenty of scope to introduce compression into the signal at every oppurtunity.

I need to learn about all that it's interesting |
i cant afford HD TV anymore... :(
|
I like it. It is why I chose my LG over the bigger brands. It didn't do this even from the same source.
