Comcast Puts the Screws To HDTV
Todd Spangler writes "Comcast, like every video distributor, compresses its digital video signals. But to fit in more HDTV channels, Comcast is squeezing some signals more than others. The cable operator claims it is using improved compression techniques, so that most subscribers won't see any drop-off in picture quality. But A/V buff Ken Fowler claims the differences between some of Comcast's more highly compressed channels and Verizon's FiOS TV are indeed noticeable. He's posted his comparative test results on AVSForum.com — and the results are not pretty."
To be more precise, they're putting the screws to the consumer. Lower quality than Over The Air (OTA), all for a premium price.
No thanks. I'll stick with my Yagi antenna which pulls in 15 stations (many with subchannels) from 30 miles away. (Though I'm quite tempted to try a Gray-Hoverman Antenna as detailed here on Slashdot, just to see if it's better. http://hardware.slashdot.org/article.pl?sid=08/03/14/2021223 )
I have FIOS for Internet but I've kept Comcrap for my TV for one simple reason: Verizon requires you to use their crappy Actiontec router if you want to use FIOS TV.
I use Eye TV to record over-the-air HD, and it's quite obvious to me the quality is much higher than Comcast's HD. That said, I can't get as may OTA HD channels as I can on Comcast. And the quality of, say, Sci Fi Channel HD shows beats the standard def Sci Fi Channel.
Still, it would be nice as a consumer to know what I'm really getting. Maybe Comcast (and anyone else) should be required to label their channels as "compressed HDTV".
rtfa, if you don't notice a difference you gotta be blind....
As a side-note, I had forgotten how great Sweden was in regards to technology. I now have a 100MBit bi-directional internet connection with no download limits, and I'm paying $65 a month for it. Then, I have a 7,2MBit 3G modem for my laptop, again no download limit, price is $30 a month, and it works quite well. Went on a 3,5h drive to my parents and was able to stream internet radio in the car the whole way. Laptop + 3G modem + FM transmitter is the way to go
We dropped Comcast's internet and cable TV the moment FiOS came into the neighborhood....it came at a good time because their internet was blacking out on us all the time. It would just flutter for anywhere between a few seconds to a few minutes to a few hours and it was a real hassle playing games online and suddenly losing connection out of nowhere...And we ALWAYS had problems with artifacting with their cable. the picture always started getting these little green boxes everywhere during a program. Comcast had a pretty extensive On Demand list, and FiOS kind of lacks that, but there's more ups than downs.
People might not have noticed up until now though.
The compression essentially scales dynamically with popularity.
So, you might have the home and garden channel, but if it isn't getting viewers it's getting it's compression slammed. SCI-Fi, in my old area, was awful on Saturday evening. I fiddled with my mythbox forever wondering why it was just so horrible and then caught it live one evening.
That said, once motorola releases an H264 based unit and not an mpeg2 receiver... there will be plenty of bandwidth. Well, assuming the rush to fill their service with tier 3 HD channels doesn't ruin it. This is all contingent on fast, affordable h264 decoding chips and I really haven't seen a good deal yet.
My big beef with FiOS is just wondering when the bait and switch will happen. I hear great things about it now, but I'm just wondering when they will turn to the cheap. Any FiOS guys want to tell us the diabolical plans in store? (I'll take made up ones too)

- half the stations broadcast in 720p instead
- it can be hard to tell the difference between a 720p station and a 1080i station except when the source material has been done really well
- the distance from your couch to your TV can limit the resolution you can see (for instance, I had *one* dead pixel on my 1080p TV, and I decided to not return it because even when I knew exactly where to look, and had a white motionless feed, I still couldn't see it from the couch)
If you're ever thinking of hooking your computer up to it though, then 1080i/p can be great.but it is important to note that most people tend to have biases towards hardware based on one or two bad experiences.

So are you saying companies should be forgiven when they give you crap that dies when it shouldn't die in the first place?
I agree, one bad experience is too small to be considered statistically significant. However... googling for "actiontec routers suck" (without the quote) gives us these results:
"Fix For Mysteriously Rebooting FiOS Actiontec Routers - Verizon
"RE: Need to replace dead Actiontec router... options
"Help! Verizon FIOS and Actiontec router keeping me from MetaFilter
"Verizon sued over GPL code in FiOS routers - Engadget"
"ACTIONTEC M1424WR Router Problem - [H]ard|Forum"
"SmallNetBuilder - Small Network Help - Actiontec MI424WR Review
"Verizon: FiOS Router Constantly Rebooting? Here's The Fix"
Just FYI, Google returned around 700 hits. And for "Actiontec router problem" (without quotes), I got 13,600 hits. Significant enough for ya?
Finally, that GPL violation Issue tells me that Verizon isn't an example of honesty... I'd stay away.
Actually, the cable co's are trying to get away from sending ALL the available channels at once, using switched digital video. However, the consumer electronics industry is railing against this change because (for the short-term) it will break compatibility with the current end-user decoding, CableCARD. Until TV manufacturers and the FCC get on board with OCAP, and start putting return-capable modules into their TV's, it's tough titties for all of us.
