Comcast, others degrade HD video quality...

High-definition television provides a crystal clear viewing experience, free from artifacts and with noticeably better quality than standard-definition television... right? Not so fast. Turns out Comcast and other providers of so-called high-def TV are intentionally compressing the video stream on many of their channels, sometimes by as much as 38 percent, degrading image quality along the way. Why? Supposedly, it frees up bandwidth so the operators can pack in even more channels.

The rest is here with links to the data and screen shots.

61" Samsung DLP 1080i/1080p HDTV. :yahoo:


I have the same TV with Direct TV and I have to agree the picture is great. I looked at a ton of TV's before buying this one and I can say I am glad I made this choice.

I can't wait for the Master's this weekend in HD. With the Master's mix on this week in HD I can't wait! Dedicated channels for Amen corner and holes 15 and 16!

NASCAR on ESPN looks great in HD. :yay:

You can actually see the debris that brought out the cautions. :lol:
 
LOL same tv here too. I have DISH and have been happy with my HD also.

I have Dish too, but haven't upgraded to HD yet. Don't have an HD TV. However, the picture quality from the satellite is so much better to being with over cable that I'm not in any hurry.

Now I can't even watch it if it is in SD......Thank god Direct TV offers everything I want in HD.:yahoo:

I had a DLP tv and got rid of it.

The picture was all right, but wasn't even close to the picture my father's plasma displayed.

I got rid of the dlp and got myself a 55" Pioneer plasma tv. The picture is INCREDIBLE.

Can't wait until we get Fios down here.

Really? what kind was it. I have found the newer Samsungs to be incredible even in SD.

I agree bout the Samsung's.........I looked at several plasmas and nothing was more appealling then looking at the Samsung DLP's.

It was a Panasonic.

I can't remember the exact model. I gave it to my aunt. I hindsight I should have kept it and stuck it in my basement (not finished yet - sigh).

The only thing that DLP has over plasma is pricing.

Well. Lifespan as well. For DLP's all you have to do is replace the bulb.

But, plasma technology is a lot better in that regards now a days.

I'm not saying DLP is bad - I probably will get one of those for the basement because it's cheaper...

Yes check out the 1080p line of Sammys because I haven't seen anything come close to it in picture quality.

You haven't looked at the Pioneer plasma line then...

Hands down the best...

Just wait until the newest version comes out.

Absolute black - contrast ratio will be irrelevant - i.e no light will escape the black portions of the screen and, by implication will have an infinite contrast ratio...

But, the dlp price point is very appealing...

Oh ya I meant in the DLP line. Plasma is getting better so fast I haven't wanted to buy one yet.

Yeah, HD on DirecTV looks good on my Samsung DLP 1080p 61" as well.

Even if you watch in HD, look in the corners and bottom of the TV picture... All carriers still compress the picture and every now and then you will see pixalation in the HD pic (in the corners and edges).

All of them do it, seem DTV has a better compression algorithm and a bit more bandwidth than others, but it is still there (look VERY closely). All of them do the corners and edges because 99.9% of viewing is at the center where compression is nil.

Now - FIOS - pure HD, no compression... rat bastards... will not see that here for a while... :burning:

Downsampling -

Direct TV 1280 x 1080i

Dish Network 1440 x1080i

FiOS HD 1920x1080i

Rate-shaping

Direct TV - 8mbps

Dish Network 1440 x1080i - 10mbps

FiOS HD 1920x1080i - 19mbps


Its clear there is a difference in HD quality.....The bad news is most consumers down even notice.

Comcast? I'm not even going to throw there numbers out there because they are ridiculously terrible.

I have a Panasonic TH-42PZ700U plasma 1080p television set connected to a DirecTV HD receiver/system, and for the most part it looks great.

Some HD channels do look a bit sharper than others - noticably channel 9 in the Va/Wash DC area, as well as the ESPN channels. HD Theater channels are awesome as well.

Some of the rest lack a certain crispness in clarity, I suppose, nearest I can describe it.

Oh yeah, the presentation of The Masters golf tournament was awesome!
