The broadcast channel has NOTHING to do with this. You cannot send user data

used for the downstream portion of the IP unicast sessions with users! (This
too seems to cause confusion. The pipe is hardly wide enough to serve even a
dozen of users, let alone 10s of thousands or more. Nor would the ISPs play
such a silly game. Come now.)
It’s not the broadcast channel Bert. It’s the use of an Internet back channel
that creates the possibility of broadcasters collecting and exploiting private
user data. And by the way, the broadcast channel CAN be used to deliver
“content” to specific IP addresses with ATSC 3.0 - in this case the receiver
would need to be tuned to the broadcast channel, and presumably the viewer
would enable the capture of content targeted to their IP address.
For example, a viewer could enable the capture of targeted commercials by
selecting this option, which in turn would send an update to the broadcaster
and enable the receiver to capture the content.
If broadcasters are to have servers that actually set up sessions with users,
for interactive, on demand, etc., all they have to do is ask the TV networks
what they have ALREADY been doing, for the past 13 years, over the actual
Internet. ATSC 3.0, aside from marketing BS, has no impact on any security
matters with users. None.
Again, Bert is missing the point. Sure, anyone can set up streaming sessions
between a server operated by a broadcaster and an IP device that requests the
stream from that server. Almost ALL broadcasters have websites that offer
access to content for which the station has streaming rights. This is typically
news stories and locally produced shows.
But Bert is completely wrong about ATSC 3.0 and data security. Perhaps he may
be aware of TV receiver manufactures who have illegally collected user data
when a TV is connected to the Internet. An ATSC 3.0 receiver is no different -
if connected to an Internet back channel, the receiver can collect data either
“illegally” (i.e. without user authorization), or legally if the viewer
installs a station app and agrees to to terms and conditions.
Can people start telling the truth, for a change?
The truth requires an understanding of the technology being discussed. Clearly
Bert cannot understand that with ATSC 3.0 a broadcaster can use the internet to
connect with a receiver, and the broadcast channel to deliver data to that
receiver.
