When I first got HD several years ago, the picture was great - using 1080 boxes on 1080 TVs. It still looks great with my Apple TV and PS3. Then, a couple of years ago, Comcast starting compressing signal to fit in more channels, and my 1080 picture started to look more and more like a 480 (not even 720), while the SD channels started to look worse than 480. This is on multiple HD boxes and HD TVs and while using a Comcast-supplied amplifer. OnDemand HD programs are better, but still not as good as using a different service, or even OTA antenna and coax. I miss the high-quality picture I used to get - it was almost too sharp, and I would adjust my TV to accomodate (and avoid the soap opera effect). Now, it can't get sharp enough. Also - if they are going to compress channels, why don't they include the expensive ones we pay extra for? I want all of my premium channels to be in HD, like they are in other states. Then, at least those expensive channels will air in 480. Agree with all of this.  Picture Quality is MUCH softer & less sharp than it used to be a couple of years ago.  The exact same live TV programming on internet services such as Hulu Live TV, DirecTV Now, etc. has a much sharper and higher resolution picture quality.  If you have an Apple TV or Roku, sign up for a free trial of one of these services and you can flip back and forth and compare the picture quality to Comcast on the exact same programming.  There is no contest.   It's sad that Comcast employees don't even understand this. ...

Yep, Comcast looks like garbage now.   As soon as Hulu Live TV or DirecTV Now offers local channels in my market, I'm leaving Comcast.  Both of those services have MUCH, MUCH better PQ than Comcast currently does (I've done free trials with both, but ultimately did not keep either of them due to lack of local channels in my market).     Also, watching the exact same programming on HBO Go on my Apple TV vs. through my Comcast X1 box is a NIGHT AND DAY difference in PQ on a 65" 1080p display.  Comcast's feed looks positively blurry in comparison. ...

There is likely a setting on your cable box that would output only 720P. There's also a setting that would let it switch depending upon what the channel was doing. - KP   Comcast is compressing the heck out of their feed.  Forget about 720p vs. 1080i.  The bottom line is, the picture quality now looks HORRIBLE.  As soon as Hulu Live TV or DirecTV Now offers local channels in my area, I'm leaving Comcast.  Both of those services have MUCH, MUCH better PQ than Comcast currently does (I've done free trials with both, but ultimately did not keep either of them due to lack of local channels in my market).     Also, watching the exact same programming on HBO Go on my Apple TV vs. through my Comcast X1 box is a NIGHT AND DAY difference in PQ - with the HBO Go streaming app winning by a landslide.  Perhaps on a 30-40" display Comcast would look fine.  Certainly not on a 65" display though. ...

I would agree, with all things the same - input, cables, settings, etc - the difference is night and day. Just watching a movie/show via HBO on Comcast vs HBO via HBO Go on AppleTV is night and day.  At times, the HD picture on Comcast looks the same as a DVD run through my Oppo Blu-ray player.   I agree, I hope the IPTV thing comes quick. Luckly I can watch most my stuff via apps on my AppleTV and for some reason the sports channels - NBC Sports, Comcast Sportsnet Chicago, etc all still have a decent picture.   Yep, picture quality for the same programming on Apple TV (HBO Go, etc.) blows the Comcast PQ away.  It's unfortunate that we pay so much money and have such bad PQ.  Larger TVs have become more and more popular/prevalent/affordable over the years while Comcast PQ has gotten worse.  I'm sure that their PQ would have looked fine when I had my first 42" HDTV, but not on a 65" screen - that's for sure. ...

Hopefully Comcast is able to work out a better solution, particularly for premium channels such as HBO.   Thankfully the workaround of using the HBO Go app is reasonable, but many stations (e.g. AMC) don't necessarily have an equivelent or always provide access to full episodes of the latest seasons.      It's sad that we need to use workarounds when we pay good money for Comcast service.  I can clearly see a difference on my 65" TV.  Comcast must test the picture quality on iPads or something.  It's rather ridiculous. ...

I really hope Comcast brings this app to the Apple TV at some point.  My old Roku 2 XS is not on the compatible list and I barely use it anymore anyway since the Apple TV can do just about everything I need.   Also, I realize pricing isn't confirmed, but Comcast would be nuts to charge anyone to use this app.  As others have stated, Time Warner does not charge for the use of their Roku app.  Additionally, I have a single TV in my house and I'm on the X1 platform.  Guess how much I pay for the X1 box?  $0.  I have never paid a dime for it in nearly 3 years with promotional Triple-play bundle packages.  So I'm certainly not going to turn in a free X1 box to use an app that I'd have to pay for!  I imagine many others are in the same boat. ...

@JEB11 wrote: Ok.  I think I'm beginning to understand where you are coming from.  Let me ask one more follow-up question.  Would you be satisfied with a 720p signal if it were possible to persuade Comcast to cut out (or at least cut back) the post-conversion shenanigans, like overcompressing and bit-starving the transmission signal?  I ask not because I'm trying to paint you into a corner, but because I'm trying to isolate what's really causing irreparable damage to the image.  That is where we should be focusing our efforts to get Comcast to do something.  Is it the conversion to 720p itself or the post-conversion processing creating the mischief?   I read somewhere about a petition demanding that Comcast return to the status quo and restore the 1080i signal.  But before I pick up a pitchfork and join the villagers in the town square for the corporate officer weenie roast, I'd really like to know if that alone would make much of a positive difference, on balance.  I personally believe that professional deinterlacing is very beneficial because many (maybe most) of us can't perform that function very well with our consumer-grade equipment.  And, there are only two ways that Comcast can do the deinterlacing for us starting from a 1080i base signal: go up to 1080p or down to 720p.  1080p isn't going to happen.  Comcast won't do it because it requires too much bandwidth.  It strikes me that 720p would actually be a very good alternative if upscaling isn't nearly as problematic for us as deinterlacing.  With a conversion to 720p, you'd get professional equipment applied to the deinterlacing function, leaving consumers with only the relatively easy task of upscaling to 1080p (or higher) using consumer-grade equipment generally adequate to the task.  If this is correct, then the fight really ought to be targeting the post-conversion processing (compression and bit rate reductions), not demanding that Comcast restore the 1080i signal.  Unless I'm misreading the tea leaves, it sounds like we could work effectively with a 720p signal, so long as Comcast otherwise leaves it alone.  I think you agree with me on that, unless I've misunderstood.  See Message 113 ("The critical issue... is less the 720p part.  720p can look good, and upscale well - IF the source encoding is very good.  Comcast is overcompressing the signal during the MPEG4 conversion, and reducing the bitrates on the program to just barely good enough.)"    At this point, we're simply speculating, are we not?  We don't know 100% WHY the picture quality is worse, we just know it is.   Yes, perhaps 720p would look fine if they didn't overcompress it.  But I don't know that we're benefiting as much from "professional deinterlacing" as you think.  Maybe we are, maybe we're not.  I'd personally like to see side-by-side comparisons.  I've always output 1080p from my X1 box, allowing the X1 box to do the deinterlacing.  When I set the X1 to output 1080i (allowing my TV to do the deinterlacing instead), I couldn't really tell a difference.  I personally think both devices handled the deinterlacing well enough.   Yes, deinterlacing has been an issue in the past (it was a BIG issue many years ago with consumer grade equipment such as when HDTVs were first becoming mainstream), but I'm not sure that it's still a big issue for most material.  I suspect that most consumer grade equipment deinterlaces good enough these days.  I remember testing 2 blu-ray players side-by-side many years ago (8+) with SD DVDs (480i).  I found a movie (American Beauty) that had some serious issues when allowing the blu-ray player to deinterlace the signal (it didn't matter if I output 480p or 1080p - the conversion from interlaced to progressive was the issue).  There were several scenes that had a lot of artifacts.  I borrowed another copy of this movie from a friend and hooked up 2 different brands of blu-ray players side-by-side into 2 different inputs on my AVR so that I could quickly switch back and forth.  The difference was astounding and 1 player handled the deinterlacing without any visible issues.   So, back to Comcast.  I don't know exactly what the issue is.  All I know is that the picture quality is noticeably worse now than it used to be.  Could 720p suffice if they didn't overcompress it?  Perhaps.  I'm not demanding 1080i, but I *would* like a better picture - however they achieve it.  I wish Comcast would have tested on larger TVs (65" and larger) and taken picture quality into account before choosing to do whatever they've done.  It looks bad. ...

@webminster wrote: As long as Comcast is going to drain all the bitrate out of the signal, overcompress it, the game ended before it started.  No amount of upscaling or other CP-end signal processing can restore the lost detail. Agree.   Perhaps if Comcast would announce plans to discontinue broadcasting SD (like DirecTV has announced), they wouldn't have to overcompress their HD channels.  I don't understand why Comcast can't just compress the heck out of SD (to the greatest amount physically possible) to allow for more bandwidth and less compression of HD.  Obviously people that still have SD televisions in 2017 don't care about picture quality.  I don't know a single person who hasn't had a 100% HDTV household for at least 8-10 years.  I haven't used a SDTV since ~2002. ...

720p may be correct for most channels, but some of the local channels still broadcast in 1080i. So outputting 720p would be downscaling in some instances. Since the X1 box doesn't support native resolution, I output 1080p from the X1 since my TV would have to convert it to 1080p anyway. ... View more

Before, when watching a HD channel (either 720p or 1080i), the live TV Buffer was between 25-45 minutes (depending on the channel) due to the fact that the MPEG 2 codec was used. Now those same channels have an 85 min live buffer since they are using MPEG 4. So check to see if any of your HD channels have a longer live TV Buffer than they use to. If it is over an hour, chances are that HD channel is using MPEG 4.   Good idea - I'll try that and test out a few channels. ... View more
