That's all included in your smart TV.

Yes.

I assume it's some customized version of Linux, but it doesn't matter
unless you're planning to hack it. Normally you're given a user
interface that will allow you access to the features built into the
smart TV, which will include apps to access Internet content providers
like Youtube, Hulu, Amazon, Netflix, and others. It may also include
some games and other miscellaneous stuff. It may even include a web
browser (mine does, but it works poorly.)

So what do you have that works poorl?. I was particularly interested in
having a browser (more than having Netflix.) so I want to avoid what
you have, if any other browser works better, that is.

I don't know what it's called, it's just whatever was included with my
Samsung TV. It's deadly slow slow slow, and navigation with the TV
remote is painful. I tried hooking up a USB keyboard, but it didn't
work and I haven't bothered to try to troubleshoot it, since it's
nothing I'm interested in using. If I want to browse the web I'll just
use one of the several other computer devices in the house.

Is this correct yet?
 
1. You hook up this "smart TV" to the power but to no other wires.
2. The WiFi connects to your router, so the TV is "on the net".
3. The TV has built-in apps to get movies on Youtube, Hulu, Netflix.
4. Some TVs have a web browser - but they're so slow as to be useless.
5. Some have a DirectTV (coax wired?) input in the back of the TV?
6. Some TVs have built-in games.
7. You can't *add* anything; it's all built in to the TV OS.
 
Is that the sum total of the advantages of WiFi on a TV?

Ya, so now you get to wait for it to boot up every time you turn it on.

A disadvantage to Smart TVs is that they quite literally spy on you. At
least one manufacturer has issued a warning about it:
 
https://www.thestar.com/business/tech_news/2015/02/09/samsung-gives-warning-about-talking-in-front-of-the-smart-tv.html
 
I really don't understand why anyone would even consider the purchase
of such a device. I suppose for many that convenience and entertainment
trump all other considerations these days.

If I turn on my TV and computer at the same time, the TV barely beats
the computer at booting.
It takes 17.86 seconds for the picture/sound to show up for the TV.

BTW, that's a hard-wired HD TV attached to a basic cable box not
providing HD.
micky <NONONOmisc07@bigfoot.com>: Sep 03 08:18PM -0400

After the previous thread, I'm interested in a set-top box... oh, that
includes the roku that I asked about before on one of these groups.
 
Well 2 more questions:
 
The descriptions keep talking about HDTV. One doesn't need HD does he?
It will output to SD also?
 
 
Are some of them wireless and can I expect it to stream continuously
with wireless B/G? Or do I have to buy a new router with N?
Remember, I don't have HiDef, and I don't expect to get it. If I buy
with AC, will it still suppport B/G, which all my other devices are?

And if you want to use one of these boxes with a smart-cell-phone app,
that means sending data tot he phone company and getting something back?
 
Or is it all within the room one is sitting in?

A 54G will be fine , I streamed all kinds of video and audio sometimes
simultaneously . And just because HD content is available doesn't mean you
have to use it - your old CRT TV will be just fine . What kind of cable are
you going to use from the ROKU to your TV set ? Mine has only component and
HDMI outputs ... no RF hookup .
Right now I'm watching Rush Hour from a DVD in a computer - I have 4
inputs hoked up , Roku and the comp on the HDMI inputs , a DVD player on the
component (yellow/red/white) and the satellite receiver on the RF input .
BTW , you really should consider a newer TV , we got a 32" LED/LCD last
spring and just love it . You can get a pretty nice unit for under 300 bucks
, often nearer 200 if you catch a sale . Available inputs are going to be
the biggest problem with older TV sets ...

Smart TVs, BluRay disk players (maybe DVD as well), and settop boxes
all are available with network (wired, wireless, or both) and make streaming
connections. Most will connect to a variety of internet services (or local
home servers). Game consoles count as 'settop boxes'.

Not necessarily. There's LOTS of boxes with these features, some have
analog outputs, either RF/analog or composite video, or both. Or, neither.

It is not the mode whether G or N or AC. It is a matter of minimum
constant download speed is needed for good media viewing. I'd say
at least 5mbps and up. No one likes stuttering video/audio. I have
50/3 service from my ISP. Always I can have download speed ot 50mbps.
I real time stream always.

The Roku or whatever will probaby input to the DVDR, which already
connects to the TVs via composite, left, and right RCA cables into a RF
modulator, and from there via co-ax to all 8 tvs (with a couple of RF
amps along the way.. I found that every two splitters I have to put an
amp.)
 
There would be a possibllity of using Y-connectors and going into the RF
modulator directly, but I think the first way, I can use the channel
selector to select the Roku when wanted. There are "channel
selectionss" for the set of jacks1, set of jacks2, and set of jacks on
the front of the DVDR. And I have remote controls on all 3 floors,
with transmitters that get relayed to the DVDR. Not installed but I
also have a remote controlled A-B switch, but only one remote for that.
I'd probably end up having to walk upstairs to change from DVDR to Roku

Right.

If I could just buy one TV with wifi and a digital tuner and all those
inputs**, I'd do it, but what I need is an output to go to the other tvs
in the house. If I had it to do over, I might have run left, right,
and composite everywhere, but too much work for me now. What was
especially hard was snaking the co-ax though the ceiling of the basement
"family room". Down 6 inches and across 25 feet, to the laundry room
with no ceiling. Maybe I used two snakes. But I made no provision
for running more wires so it would be even harder to do more wires now
than it was to do one wire the first time. I know there is wireless
transmission, but then I'd need 6 or 7 receivers (I rarely use the tv
in the attic these days, mostly for aiming the attic antenna.) ,
including one in the bathroom where there is no room, and wired is
certainly reliable. I"ve had those 2 signal amps running 24/7 for 31
years without a problem. But better to have 2 power amps running.
they don't use much power, than to have 6 receivers running.
 
**Even the big ones only have speaker outputs and maybe unamplifed sound
outputs (to go to the stereo) but I only want a small TV in the bedroom
where the DVDR is, and they usually don't even have speaker outputs
(although they need them the most.) . In the bedroom I use the earphone
jack but run it to a mechanical rheostat (mounted in a Pong remote
control box), and from there to an amplifiied computer speaker. So I
can control the volume with a knob instead of having to use the remote.

But G is slower than N which is slower than AC, so I think the wireless
too can bottleneck the signal. So I think the mode does matter.
Except Terry tells me that B/G is fast enough.

But even if the output connector is, say, only HDMI, it can still be set
to output a standard definition signal, can't it? What if someone
has one HD tv and another SD tv? Does that mean he can't use the
expensive box?

IMO, G isn't fast enough for me and you are correct, AC is thus far the
fastest but here's how it works. If you have a G router, any other
device with G/N/AC capability will only use G. If you have an N router,
any device with G/N/AC will use only N and of course, if you have an AC
router, any device with AC capability will use AC. If a router has AC
capability but a device has max of N, it will only use N. Bottom line,
BOTH devices require the same capability in order to meet the speed they
advertise.
 
Also keep in mind, even if you have the fastest router and device, your
speed will still depend on what you're paying your provider.

It doesn't seem like you understand the problem.
Maybe you do, but it doesn't seem like you do.
 
The problem is they used, as a salt, the ESSID!
 
That's a pretty dumb salt.
 
It's even a dumber salt if the owner leaves the ESSID at the default
values, or, if the owner changes the ESSID to something common.
 
Because of that, anyone with the tables already has your hash and is on
your wireless network already.

You have to realize what Jeff is trying to tell you, which is that any
common name for the ESSID has *already* been hashed.
 
In that case, WPA2/PSK is worthless.
 
Use a common name, and you immediately have no security no matter what
you set the security to.

The light bulb in series is a bad plan; the power supply will, in order to deliver
regulated output power, draw higher current due to the lower input voltage,
and fry the fuse, even if it isn't faulty.
 
Most common problem that makes the fuses fry: shorted diode in the AC
rectifier (usually full bridge).

Yup, that's the REAL problem, FAKE UL and other certification stickers!
Very scary. My mother in law got some surge suppressor strips some time
ago. They had UL labels. If you turned them over, the plugs would fall
out, even the FIRST time they were used. No grip to the contacts in the
outlets. I sent the info on these to the UL comments address, and never
heard back from them. I expected they'd WANT to know about fake labels, but
apparently there are tons of these.

The light bulb will limit the current to around what the bulb is rated for.
That is a 100 watt bulb will limit at about 1 amp and a 60 watt bulb to
about 1/2 amp. At low current the bulb is like a very low resistance and
as more current is drawn and the bulb lights up it acts like a higher
resistance.
