Re: Nice..

...but it won't be like Star Trek. From an imagination perspective, the concept is incredible but unless all that we know about physics is wrong, a holodeck that converts energy to matter as easily as a modern flat-panel creates 2D images is all but impossible. In nature, exploding stars create heavy elements. To think that we can connect dilithium crystals to holodeck emitters and get matter or even generate fields that feel, smell and act like matter is pretty far fetched.

What's far more likely and maybe even plausible is creating the holodeck in our mind like Inception or The Matrix.

You are probably right that regardless of how it's created, it would mean the end of civilization.

I may be showing my geek here, but that's not quite how the holodecks are described as working in Star Trek. A holodeck supposedly creates a visual hologram that is customized for the individual eyes of each user. Matter or forcefields are only used for props and set pieces the user actually touches (with material objects supposedly seamlessly introduced and removed by transporter as needed). But yeah, it's pretty much all fantasy without the real-world physics to back it up.

You are probably right that regardless of how it's created, it would mean the end of civilization.

On that we can agree.

Might be good for movie distro

Way overkill for home use but movie theaters may benefit from that type of digital projection capability. No law says it has to be streamed live. That 8K is getting toward IMAX HD territory which I think is 10000x7000 or something like that.

digital theaters are already using 4K display technology because you need to be that far away for it to be of any use...8K will be of NO use to you since you need to be a block away with a screen a block big to notice...

The human eye typically can receive about 10B triangles in stereo (that is how we form depth), so to do 3D it will take about 8kx4k at 8 feet to make it seamless--however compression artifacts can cause some unusual side effects. That is why IMAX is going to dual laser projectors (4k) which would pretty much be good enough, although not imperceptible. Laser projectors will ultimately solve the problem over time. That and some are going to 48 FPS for motion issues.

8K would probably be broadcast quality, and then from there they would hack it up with compression for home consumption where as people have said visual artifacts can crop up, maybe to 4k in ten years or so.

3D will be the kicker over time, and this will need new advanced algorithms to keep the bitrates reasonable.

All of this is going to take big pipes, and that means fibre is in....

I don't know if it is Cox or if it is the network but sometimes, particularly for sports, CBS HD is so over-compressed it is annoying to watch. It's like the image is made of Legos. But I see the same with some OTA HD...like networks want to punish you with degraded picture to drive you to cable or DBS where they get rebroadcast fees.

Last time I checked, we're looking at 500mbps for 4k streaming. Most content servers out there have gigabit lines and a HDD RAID array. Streaming 4k is going to require a huge jump in server network speeds, cheaper bandwidth, faster and cheaper SSDs, cheap 4k display tech, and of course we can't ignore the simple fact that there's no physical distribution method short of shipping hard drives that can store the massive filesizes of 4k video for. Oh yeah, and there's still the whole battle to get everyone to start filming their stuff with $50k cameras. And this isn't even going into 8k territory yet. Oh, and I didn't even mention the challenge and expense of wiring up America with FTTH.

More like 30 years, I think the first CD players came out in the early 80's? I bought one in 86 for something like $120. In todays money it wasn't cheap and the CD's costed about double what an album cost. BTW I don't think 9600 baud modem speeds were available yet... and I used a cassette for a tape drive.

They will need to rebuild cable systems

They will probably need to rebuild cable systems to handle that high of resolution and we are talking about having to build dual cable systems to handle that much bandwidth. We used to have a dual cable system in Springfield (MA) and they rebuilt it back in 2002 with a single cable system. I moved here in August of 2002 and the new system went online in our neighborhood in December of 2002 (our neighborhood was one of the first to go online). The A/B cable system was a pain in the butt as you either had to rent an analog converter (despite having a cable ready TV) with automatic A/B switching or you had to fumble with an A/B switch to take advantage of a cable ready TV.

They could have used an A/B system with digital as they could put the standard definition programming (both analog and digital), high speed Internet and VoIP on the A side cable and put the high definition programming and VOD streams on the B side cable. I think there is an attachment that goes on the back of set-top boxes that is used to accommodate an A/B cable system (at least on older set-tops). I know the Motorola DCT 2000 boxes have an attachment that allows analog pass-thru as the Mediacom boxes in Cedar Rapids (IA) had them. They could test a high bandwidth dual cable system in Springfield (MA) as most of the housing is wired for dual cable from the A/B cable system (although the plant has been rebuilt and only one cable line is in use but most of the customer premises wiring is still dual cable).

Google Fiber

Well, corporate apologists who were asking what we need Google Fiber's symmetrical 1 Gbps for: there's your answer!

8K Internet streaming video. If you thought 1080p was a big leap from standard definition, then this will blow your mind. This is 16x the resolution of 1080p. 1080p was only 6x the resolution of 480p.

Once compression codecs for this new format are improved some more Google Fiber ought to be able to handle three 8K streams at once.

Now I'm sure there will be some tool who will come into my thread and try to damage control this by spouting lies like "nah dude, human vision isn't good enough to see more detail in resolutions higher than 1080p!" or "nah dude, 8K will never happen, we should all just be content with the current mediocre state of Internet video forever."

Cable companies already compress the heck out of HD... and while I don't know if off air broadcasters do the same, there's is definitely a noticeable quality difference between the off-air signal and the cable display of the same channel.

If compression is used... what's the point?

360 Mbps now, probably 100 Mbps with newer compression

I think that with new developments in compression, (and chips decompressing it live in your tuner unit) a Ultra HD stream can probably be brought down to about 100 Mbps without any noticeable loss in quality.

That said, if eventually we develop a good standard with more-or-less 100 Mbps as the bitrate, most cable carriers will be able to carry at least 10 UltraHD stations with some changes to their current network, and probably a lot more if they get in to upgrades to 1.4, 1.6, Ghz and beyond. FIOS will also be able to deliver this over their network. DirecTV has already said that on their next satellite launches (2014, 2015 and 2016 will see new launches) they will be "Ultra HD ready", so they can probably carry a pretty good number of Ultra HD channels, and I am sure Dish Network will also be able to.

Who will be lagging behind? AT&T U-Verse. Without updates to their infrastructure, they will not be able to carry even a SINGLE Ultra HD station and deliver it to their customers.

What to Use it For

This technology along with a decent 3D system that does not require glasses could result in some interesting porn movies. Considering the past this might be what would jump start the technology.

I wonder if the Ultra-HD would work via antenna. If so less compression. I say that because the current compression on cable makes HD and regular TV service inferior to a good antenna. I would expect the compression on an Ultra-HD signal might reduce to to a good HD level.

I'm very hopeful that by the time we have the bandwidth for multiple 8k streams TV providers are no longer relevant.

When we do get enough bandwidth for that. You can be sure that it won't be thanks to the incumbents.

anything past 1080p is 10 or more years off.. we dont' fully take advantage of 1080p at all. 40% of all hdtv's made only have resolutions upto 1080i (65% of 32" or smaller screens are 720p primarily and 1080i capable).

this is not really a consumer friendly technology yet. these are really meant for super large screens such as in a war room, movie theatre for the super rich, sports arenas, big city electronic billboards.

More than 10 years. We don't even have 4K TVs on sale let alone 8K TV and it would take 10 years for such TV to come down in price and be in enough homes for cable to make this technology available to consumers. Even then the amount of content available in 8K format will be minimal for several more years. definitely at least 20 years away minimum. Look how long it took HDTV to take off.

Compression

I really don't want it if it's going to be compressed to hell. Many Comcast HD channels have heavy amounts of compression artifacts because of broadcasters cramming as many channels they can using MPEG2.

I pray they go to High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2. Yes it will require new hardware at the customer end but we need to let go of old hardware, even at a hefty price. Clinging onto legacy hardware doesn't get us anywhere to reaching the full potential of current hardware.
