| 3840x2160 using H.264 would use only about 40 megabits per second, about four times HDTV compressed to H.264.
Good looking broadcasts of 1080i/60 or 1080p/30 H.264 HDTV go at about 10 Mbps, about half the approx 19 Mbps for MPEG2 HDTV. Multiply that by 4 times and you've got 40 megabits per second. Since 1080p/60 at H.264 is more like 20 Mbps minimum for something good looking, so if you want 2160p/60, multiply this by two to get 80 megabits per second.
Now, since pixels are very small at 2160p/60, compression artifacts are slightly harder to see, so you may get away with say, 40 Mbps for 2160p at 60fps. This would be equivalent compression ratio to 1080p/60 at 10Mbps, or 1080p/30 at 5Mbps, or 1080p/24 at 4Mbps. This would be filled with too many artifacts at these lower resolutions. | |

| Re: so... Which would look really nice, however I'm sure an actual video compression algorithm would supply better results while not sacrificing too much quality. I'd be happy with 4096x2160 in H.264 not sure what bit-rate you would need for adequate quality. I believe I saw somewhere that some blu-ray videos are encoded at ~40Mbps video bitrate and I assume that's 1080p. So for 2160p that would be like ~171Mbps assuming that the video was in 16:9. So if you wanted to do a compression ratio similar to bluray it would come pretty close to 171Mbps. Sounds like they need to lower the gpon subscription ratio. Maybe instead of 10 homes per gpon(i'm sure they would oversubscribe way beyond this anyway) You could do 2-3. Bottom line is they will just need 10Gig GPON's if people want to be able to watch multiple streams of this pixel size. We've barely even started viewing 1080p content let alone 2160p. 2160p will have to be reserved for a hard-medium until the infrastructures can support 4x streams per household or whatever their rule of thumb would be. | |

| 80 inch TV? How are you supposed to fit that in your room? Ok, some people have big living rooms, I'm sure, but my living room wouldn't accommodate a TV anywhere near that size. We have a 32" screen and that's all we can fit. *Maybe* we could go to 46" but that would be pushing it. (We'd have to buy a new TV stand and would probably obstruct one or two windows.) | |

| Re: Does everybody really want said by morbo :non-HD sets are still being sold too. and those are much cheaper. until the price is comparable, most people won't make the switch. plus, many people will just wait until their current set dies. i've had mine for about 9 years and it's doing fine. While I do have an HD set in the den, I agree with you about just waiting until a tv dies before getting a new one. I would love an HD set in the bedroom, but my little 20" analog tv is over 10 years old, and the picture looks as good now as it did then. I can't justify getting a new set yet. | |

Content providers follow NTSC and ATSC standards, regardless of how DBS and cable delivers it. The content will be at ATSC resolutions and that or worse is what will be delivered to the end user. | |

| Re: They won't deliver it because it won't be an ATSC standard But first Microsoft would release the Xbox 4pi (get it math humor...) with a super hddvd player. Oh and we'd have to have long discussions on BBR whether porn will be a major driver of which standard gets adopted. Betamax versus VCR arguments will be rehashed and at the end of the day Sony will triumph again. So we can all go back to bashing the PS4. | |

| not jpeg2000 ~4096x2100 is the resultion of the newer chips used in large scale projectors at some digital cinima's altho not at 60 fps. I can't see mjpeg or jpeg2000 ever being a distrubtion medium for vidoes. I'm sure using x264 the video size would drop, and CPU need would most likely be the equivalent of a q6600 or slightly faster depending on frame rate/bitrate. | |

| Okay I'm confused. Wasn't the whole point of HDTV partly to get rid of the ATSC/PAL mess? Or are there separate resolutions for HD depending on what the country uses?
Even given that I'd bet that most tv's can read either format just fine. I liked how the article said that even with multicore processors the capability for UHD wouldn't be there till at least 2012. I can't imagine them being able to manufacture a thin enough screen at 80 inches with low enough defects to make it viable by then though.
Still, it's nice to see technology progress. I remember people complaining about the digital transition and how it will mean that TV technology will advance more than it has in the analog days but such is life  | |
