After that period of time, they will evaluate their next upgrade. I hope that 8k is ready by then to take over as a universal standard. It truely is the holy grail. From what I've seen 4k, it looks impressive. I would rather have 8k as a universal standard and be done with it. No further need to upgrade until hologram TV.

I just don't see the masses upgrading to 4K TVs. And OTA is for the masses. Always has been, always will be. Plus it is estimated that only 20% of the USA households depend on OTA for their TV content. The other 80% have Pay TV.

As far as changing OTA broadcast standards, it ltierally took 10 years for HDTV broadcasts to start after serious discussion was started about upgrading the NTSC standard. The only way IMO 4K OTA broadcasts could be made in a shorter timeframe would be if they fit into the current ATSC specs so no new OTA broadcast standard would be necessary.

Well 4K UHDTV will deliver higher resolution, higher frame rates, improved color space, and higher bit depth. I know that 4K UHDTV adoption will take a while but I would point out that it took 12 years for HDTV to make it into half of US homes.

There have already been ATSC 3.0 discussions about newer modulation systems, HEVC, and 4K. Here is a link to a document about ATSC 3.0 that was made by the National Association of Broadcasters. The planning team report for ATSC 3.0 was finished last year and since than the TG3 has been having regular meetings.

It's not a completely new standard that will make everything obsolete, it's just an improvement in resolution. I don't see it as being much different than how some broadcast in 720 and some in 1080.

From a consumer standpoint, the switch to 4k and 8k means all new hardware for consumers. They just did this for HDTV. You think they will do it again for first 4K then shortly afterwards 8K? I think not.

You're comparing apples to oranges. Switching from analog to digital required new tuners because the old analog tuners couldn't process a digitial signal. But in this case all that's happening is the mpeg is in a higher resolution.

You may not be aware of this, but all digital TVs convert all resolutions of mpeg to their native format before displaying. If you have a TV with a 1080p native resolution, you can play a 720p or 480i broadcast just fine. The TV always converts it to 1080p. You don't have to buy a new TV to watch ABC in 720p. Do you think all those people who had a 768 TV couldn't watch a 1080i broadcast?

Higher resolution and frame rates I can believe. Better than 8 bit color space and better than 4:2:0 Chroma Subsampling - when I see it I will believe it. Still waiting for the promised Deep Color for HD.

Heh, as you see I am flexible and now we have changed roles. In my previous incarnation I've been saying 4K is stupid but you did not want to listen. So now I am saying let's move to the 8K just end those stupid discussions about resolution once and for all . 8K is an overkill good to kill the resolution issue.
On more serious note, the 8K might be needed for scenarios extending beyond the TV, e.g. using kind of surrounding displays. Actually there are already gamers who are surrounded by no less than 6 2K monitors. In quite near future you may see guys sitting at their desktops and surrounded by 3 4K monitors. These are 12K computer monitor scenarios. One can imagine then the 8K TV scenarios with flexible displays.

Founding FOBTV members comprise the Management Committee:

*Advanced Television Systems Committee (ATSC)
*Canadian Broadcast Corporation (CBC)
*Communications Research Centre Canada (CRC)
*Digital Video Broadcasting Project (DVB)
*European Broadcasting Union (EBU)
*Electronics and Telecommunications Research Institute (ETRI)
*Globo TV-Brazil
*IEEE Broadcast Technology Society (IEEE-BTS)
*National Association of Broadcasters (NAB)
*National Engineering Research Center of Digital TV of China (NERC-DTV)

*The first Chairman of the newly formed FoBTV Technical Committee is;
Dr. Wenjun Zhang, Chief Scientist, NERC-DTV.

*Three Vice Chairs were named:
Dr. Yiyan Wu, CRC’s Principal Research Scientist,
Dr. Toru Kuroda, Director of NHK’s Planning and Coordination Division
Dr. Namho Hur, General Director, Department of Broadcasting System Research at ETRI.

Together, they will lead the FoBTV Technical Committee's solicitation and evaluation of technical proposals and recommendation of major technologies to be used as the basis for new standards.

^^ the 8K switch is a big deal!

Now time is coming for an ultimate standard, once and for all: Octo HD, 120Hz, 10-bit, transparent compression. No excuse for techies it is impossible to do. Get it done asap .

I think this is one of the wiser initiatives taken by the broadcasters. This will ensure that when UHDTV 8K broadcasts eventually starts, it will be the same broadcast system all over the world. No more differences in equipment standards or need for transcoding of material between broadcast standards zones.

There is a good reason for why 10-bit video has yet to happen. It would have required new MPEG-4 AVC Hi10P video decoders, a large increase in the maximum bitrate of the decoders to support the Hi10P profile (which was not designed with consumers in mind), and it would have been a benefit only to the HDTVs that could display 10-bit video. The UHDTV standard uses 10-bit/12-bit video and supports up to 4:4:4 chroma subsampling. I think that UHDTV will be taken into consideration when they make the various profiles for HEVC in the future.

If that should be the case , my bet would be China rather than Japan.
The initiative was Chinese, the first meetings was in Shanghai, the first Chairman of the newly formed FoBTV Technical Committee is Chinese; Dr. Wenjun Zhang, Chief Scientist, NERC-DTV in Shanghai.
The vice chairs are one Chinese working for Canadian company (CRC), one Japanese(NHK) and one Korean(ETRI).

Not necessarily but Japan has long history in introducing their own HDTV systems which were running only there. China is black horse in this race, they may also press for or introduce their own OctoHD. Things may be happening quicker then one may think.

BTW there is also a way for resolving the 8K/4K issue by introducing hierarchical broadcasting and compression standard. There would be then compatibility between the both, one could start with the 4K and the 8K would be downward compatible extension of it.
