There a new codices called VVC "Versatile Video Coding" better than HEVC by 40%!:clapping

Might move up to 8K video 4360p 120 Fps in the future.

Too early think about this new codices systems?

Let me know what you think of it?

Just Google it on VVC.:biggrin

ATSC 3 is supposed to be adaptable to upgrades. Any chance this might get incorporated?

CODECs (not codices -- the plural of codex) are implemented in hardware in consumer electronics gear. They aren't something you can download and install.

HEVC took perhaps four years to be practically delivered (it was implemented in hardware in Spring 2014). VVC is slated for release in 2020 so it isn't likely to make it into the first couple generations of Next Gen TV tuners.

AVC was approved for use in DTV back in 2008 but it never really made it into widespread use (Trip notes that some channels are using it).

Next Gen TV can't wait for VVC to be implemented in shipping tuners and televisions so you're stuck waiting for many of those devices to age out before the broadcasters can seriously consider using a new technology.

As for 8K and 120fps, there's absolutely no point implementing it in broadcast television.

Lastly, your suggestion that a doubling of compression efficiency will allow the broadcast of content that involves potentially eight times more video data (twice the width, twice the height and twice the frame rate) is not well-reasoned.

From what I understand the Human's eyes is at 10'000x7'800 that's what they say.:biggrin
This assumes that the image fills the entirety of the eyeball's field of vision (some part of which is entirely blanked out). The "resolution" of the human eye is not uniform across the entire field.
I could be wrong on that, and I hear the Eagles and Hawks have better eyes than Humans.:rolleyes:
Their vision system is much different from that of humans. They aren't really comparable as they were adapted (or designed, if you prefer) for different purposes.

8K OTA? ATSC 3 is a 4K capable OTA technology. To go to 8K would require a completely new technology (ATSC 4?). As mentioned, it's a hardware implementation, not a software upgrade, so don't hold your breath.

I'm sure 8K is already standard in Japan or else they wouldn't be broadcasting the 2020 Olympics in 8K. If you want to know the future of technology, look to Japan. They had HD (MUSE) back in the 80s. It was an analog standard with not quite 1080 lines, but it was way ahead of anything we had in the U.S. at that time. You can actually find recordings from the MUSE system on YouTube. They filmed an outdoor scene of NYC using MUSE in the early 90s and then used that footage on a demonstration D-VHS in the early 2000s to sell that format in the states.

Yes, they had a dead end. Hardly trail blazing.

“Broadcasting” in 8K? In ATSC 3 or ??? or online?

I’m sure both people watching in 8 K appreciate it. Yes, I exaggerate, but not much. 10,000? 100,000?

Japan has had an 8K HLG HDR channel for about a year now receivable via Ku band satellite. It's called NHK BS8K. You just have to buy the proprietary receiver to view it.

It also has AAC 22.2 channel audio. (it also has legacy AAC 5.1 and 2.0 audio as audio IDs #2 and #3)

Anyways, the bandwidth is there -- Great looking 8K TV channels are potentially deliverable with HEVC and a DVB-S2 transponder already. NHK is able to deliver BS8K as 8K 60 FPS HEVC @ 80 Mbps.

It's great stuff and a good example of what could be achievable here if Americans had the same amount of appreciation for technological advancements as the Japanese do.

Hardly a standard outside Japan. To suggest that MUSE was the future of TV broadcasting is ridiculous.

Japanese TV is much more like the BBC's model than it is the US model except the BBC uses more common broadcast standards.

techmoan talks about it in a laserdisc.
