Question for Radio/Television Engineers
Scott Ryan

Posted on 12/31/2013 12:35:00 PM PST by publius321

I'm far from an engineer, which is why I am posing this question. Pardon me if my line of thinking is askew.

My rudimentary understanding of what & how digital television stations broadcast is that they have 5 "channels" over which to send their signals now.

My question is: Is there currently a way or do you think there wil be a way in the near future - for television stations to offer --high speed WIRELESS Internet service-- as opposed to mere broadcasting of program, which of course is becoming obsolete.

In my basic thinking, I presume that 5 channels are obviously not enough for two-way communications between their transmitters and the routers of millions of people. (As an aside, this would probably require the invention of some kind of router network throughout the broadcast area of each station but I'm not as concerned with that at this point.)

But through "frequency-division multiplexing" or digital compression along the way - what are the chances of this technology coming to fruition within the next few years?

I ask this question here at Freerepublic.com because I know there are many geniuses within reach here at any given moment.

If the signal actually reached my house reliably, it might work okay for receiving web data — but there’s no way other than dialup for me to tell it what to send. A system like that would work, and in fact that’s how TiVo used to operate in the late 1990s, same goes for pay per view over small dish. Dunno how it works now.

I played with PowerLine Networking in the mid 90’s. Those were the typical advertised speeds at the time. I see a “2004” watermark in one of the illustrations so I suspect this “how-to” is at least 10 years old.

That was (and apparently continues to be) the problem with BPL - pathetically slow.

As Yo-Yo pointed out, broadcasters transmit and do not receive any signal.

Far better than that would be if the electric companies were allowed to provide Internet service over their existing AC lines.

This will never happen, and I will oppose every attempt to do it, as do thousands of my fellow ham radio operators in the ARRL. The potential for this to completely DESTROY the use of the HF shortwave bands has been proven, and this should not be done.

So here I posted a question to intelligent people and you inappropriately crash the party.

Now, you are obviously a grade school bully who never grew up. Anyone who reads your posts will see how pathetic you and your attacks are.

But I wonder if you have the slightest clue how juvenile your unsolicited attacks truly are. It is perplexing how someone who behaves this way can be welcomed into -any- community.

It is sad what a horrible existence yours must truly be for you to find your identity in being such an ugly human being that you would proudly exhibit it to the world.

I may be wrong, but it was my impression that post was meant to be amusing.

“Secondly, there is currently no back channel, or any way for your computer or other device to talk back to the television station to request a web page, upload photos, etc. That backchannel would have to be over some other system, either a dial-up telephone line or a wireless cell phone service of some sort.”

Yes, I was aware of the lack of back channel but wanted to deal first with the question of whether they could -send- unique/separate data to large numbers of people.

Ideas for sending back info in and of itself can make for interesting contemplation and sharing as a group.

There are 10 kind of people in the world. Those that know binary, and those that don’t.

First things first.
Here's your prize tee-shirt.



Second, words of advice.
If you see posts you don't understand,
sometimes it's better not to respond.

By the way, I looked at your home page, and your dog is so handsome.

There is already a method defined within the ATSC standard to multicast data. the problem again is the limited amount of data available. When the ATSC standard was developed 15 years ago the text data carousel was adequate. But today everyone wants to stream video, and that’s what TV stations do - four or five streams at a time.

Thanks for the ping, and a Happy New Year 2014 to you.

As for me, I subscribe to the DISH, dumped cable a few years ago..
