I am in agreement with your sentiment about 3-D TV, Bert.
The defining moment for me was when I was sitting in a conference in Yokohama several years ago. One Japanese engineer stood up and asked the panel (largely consisted of TV manufacturers like Panasonic and Sony, and a couple of broadcasters): "I don't know about you, but I watch TV while I have supper. Do you expect me to wear glasses while I eat?"
When I heard that, I said to myself, "Say, no more."
"TV was stuck at a stage analogous to that of AM radio (limited to a pitiful 3-4 KHz audio bandwidth by the RF spectrum allocation rules)."
That might be confusing. I was talking about AM radio being limited to 3-4 KHz, not TV. Was just trying to draw an analogy
Although in fact, network TV audio WAS similarly limited, until the mid 1970s, to just about 5 KHz. The NTSC and some of the PAL standards didn't limit it, but the network feeds did.
I am one of those who was begging for TV to get past the bronze age, way, way back in the 1970s. TV was stuck at a stage analogous to that of AM radio (limited to a pitiful 3-4 KHz audio bandwidth by the RF spectrum allocation rules). TV didn't get out of the antedeluvian standards until the 1990s, with the advent of the digital standards.
So HDTV was a long time coming, and cleverly designed to use the same spectrum slices as analog TV, only a lot more efficiently. The Olympics in HD are fabulous. All you have to do is see the footage from Olymics several years back, to see how abysmal it was then.
On the other had, I have never seen a single example of consumer demand for 3DTV. At first, I only saw articles on EE Times about it, and the entire push seemed to come from the supply side. You go to stores, and it's always been pretty clear that few are interested. My bet is, any 3D sales are misleading, because the 3D feature is simply a standard item in the larger and more expensive sets.
One problem is the glasses. Another problem is the potential for queasiness (especially among people who don't wear glasses). Another problem is the spectrum needed by all of the existing 3DTV standards, although at least in principle there are more clever ways of transmitting 3D. But the existing options out there are very wasteful, UNLIKE what HDTV managed to do.
Just because a lot of kiddie movies come out in 3D, and people seem to enjoy that occasionally, does not mean that people want it as a steady diet.
UHDTV is somewhat similar, certainly with respect to bandwidth usage. And it's also not really all that beneficial for TV sets of, say, 55" or less.
I hear what you're saying.
But of course, there were many people in the past who claimed, "who needs HDTV?" And a few decades later, they are enjoying the fruit of the labor.
8K will be, as the EBU guy says in the video, the technology for our kids.
You're surprised by this? I'm surprised anybody sells 3-D TV sets that require glasses. You know, maybe they should give us football helmets to wear containing those 24 channels of audio properly positioned on our head too.
Of course, in most of the swim meets, gymnasiums, or events where a British athlete is participating, you can't hear the commentator over all the screaming and background noise. They could save the bandwidth and jam pink noise audio in at the box on my curb.
I really like what NBC did by packaging the best of American interests into prime time. And I appreciate most Internet outlets' and bloggers' warning of spoiler alerts if they reveal live results.
Just because technology allows 8K resolution (if price is no object) doesn't mean people want it, even with good programming. People are spending far more money on cell phones and tablets to watch small screens. Broadcast isn't dying, but the last thing I need is to see hillbilly TV or the Kardashians in 8K 3-D. I might watch Bruce Jenner as a decathlon-ian, but then what?
Oh, yeah, my cable box reset itself again last night in the middle of watching Olympics. The fundamentals are still failing us some times.
