Craig's favorite modus operandi. And now, Craig argues points that everyone
already knows.
Yes, any interactivity authored to accompany a TV program is of the
stations, or creators choosing. You could consider closed captioning a
form of metadata delivered information
So, hype-meisters, instead of trying to bamboozle the unwashed masses, how
about you instead say things as they are? Any form of "interactivity" you are
describing here, i.e. "interactivity" with the content already broadcast, is
functionally NOTHING NEW to TV watchers. Explain that. Explain that the viewer
is not able to request whatever he likes.
Hyperbole consists of deliberately using words that you hope the reader will
misinterpret, so that you can pretend that something is a bigger deal than it
really is. This qualifies in spades.
Demos of the techniques I am taking about have included the ability to
display information about the program and actors,
BFD. Explain that all you need for this is to use ATSC 1.0 subchannels. And
explain that beyond this, ATSC 1.0 already supports A90, capable of more
advanced forms of this sort of thing (such as transmitting content in
non-real-time, which in fact is of marginal value). People are entirely
familiar with interactivity over the Internet, that they can get more info on
any topic they like. In short, instead of this apologetic idea of
"interactivity," how about the station, or TV network, simply make a web site
available, to get whatever additional content? (Oh yeah, they already are! I'm
so impressed by Craig's deep insights.)
And, for those who can take the idea of Internet use to the next step, at what
point is the OTA one-way broadcast no longer "the main event"? At what point
can the TV industry use Internet distribution as the anchor, rather than the
linear, one-way broadcast channel? (Oh yeah, many of us already are!)
Needless to say, today's connected TV devices have the hardware and
processing power to deliver this form of interactivity - but they use
the Internet
Needless to say, we are no longer back in 1991, Craig. Even back then, many
people knew about the Internet. To pretend that ATSC 3.0 is the first TV
standard to offer "interactivity over the public airwaves" is simply not true.
It is not "the first," *and* we are way beyond being impressed with such
limited ideas of "interactivity."
And as to the "back channel" point, what baud rate can a prime time user
expect? You need to give us that number. Otherwise, you will continue to miss
the obvious. Any of today's broadband links to households can beat this by
multiple orders of magnitude. Even old-fashioned dialup can beat this approach
in every way.
3 mbps of data to every home that choose to use it.
Hardly. It's maybe 3 Mb/s aggregated, shared among all homes tuned to the
station. Most people would understand this point. They expect more like 20+
Mb/s for themselves, not that capacity shared among 10s or even 100s of
thousand households.
Who said anything about on demand programs Bert?
Really Craig? Let me quote one example, from the Triveni presentation we have
seen:
"App-based Services - Unscheduled content
Consumers access content on-demand via an app
Consumers choose what content to access and when"
Where is it explained that this feature is only based on Internet delivery, not
the public airwaves? It's obvious to me, but it's never even hinted. The
innocent will no doubt assume the ATSC 3.0, and its broadcast channel, are
instrumental here. Instead, this has been possible for at least the past 10
years!
