Will this basic wiring setup work? *PIC* *EDIT Clarifying something*

Satellite coaxial output (s-vid is going to main tv, but I need the signal split to the other rooms in the house) will be the "sat out" part at the bottom left. This output will be going to the OUT part of the splitter. Then the other part of the double splitter is OUT for the cable modem. Then the line between the double and quad splitter will be used for sat signal travelling one way for output to those 3 tvs, and as a dual way for the internet.

I realize that the ins and outs are buggared, but that doesn't matter with cable in anyway does it?

So really I guess my question is I know that cable tv and cable internet can co-exist, and they could for sat too, since it's just video/audio of the same nature, eh? eh. ;d

*EDIT* I think that there may be confusion here. The coaxial SAT OUT is NOT the line that goes between the satellite receiver and the dish. That line is already an independent separate line. By SAT OUT I mean the opinional output from the receiver which goes back straight in to the TV. How can this signal be different from the line that would go from a, say, a digital cable receiver into the TV?
 
You can't run two signals on the same line.

Also, you'll need high-pass filters before the TVs if cable internet is in that signal.
 
hmm never tried it but like baddaddy says, i don't think they're compatible with each other. Cable internet works by sharing it w/ the cable TV signal. I think sat TV's signal is different.

And if such a setup can work, u might need a repeater/signal amplifier in there.

but if you do that, and there's static, the amplifier will also amplify the static 🙁


i don't know much about this anyways so I can be wrong.

why not just have it separate? heh

to filter out the cable internet noise to the TV..right? i think hehe...

u can probably make ur own if u had an oscilliscope (sp) and radio shaq down the street...

i donno..

Saves on running lines down walls.

Anyway thanks all I'll think of something else!

why would you need to run wires? 802.11g is good stuff

So is money and I'll have a lot less if I go with something wireless to handle the internet side of this!

high-pass filters? hmm never heard of this before. would this improve the cable reception going to my tv?

anyone have a link to where you can purchase these filters?

Well I do recall when I had cable internet and tv I'd run them straight to their appropriate receivers (ie, a splitter to the cable modem and one to tv) without a filter. DSL does need a filter, but cable doesn't need one per se.

how many computers could you possibly be hooking up?

A single computer, but I'd need a wireless transmitter and network card and I've neither now. Currently all wiring is setup in the house with exception of merely dropping one down a wall! And I'll have to drop it down regardless of what I do.

This is what I thought too. I've had DSL and needed the filters with that.

If I needed filters with the cable, I'm sure the cable guy would have said something when he ran the line to the house...


I dunno..maybe someone knows something I missing...
 
The high pass filters eliminate the internet signal going to your TV. Otherwise you would just have a bunch of noise on the screen.

They can be had at Radio Shack.
 
You can run satellite and cable on the same line. The question is will the internet signal run along side what's coming off the dish. You can get diplexers and combiners at the store that would allow analog and digital signals to share one RG6.

But the "satellite signal" won't be on the same line, since that's got an independent line between sat receiver and dish. The sharing will only occur between the cable internet, and the "pure video/audio" feed FROM the receiver TO the TV (or to the splitters which will then go to various tvs).

Heh, I guess I should have re-read the post. I was in between rounds of Mike Tyson's Punch Out when I read/replied. Why don't you just try a mock-up of what you want to do before running any cable. Then all you'd have to do is return a splitter or something.
 
Skoorb,

Let your cable modem have the shortest and most direct route to the input as possible. My suggestion is have the input connect to a 2-way splitter, one going to the cable modem and another going to another splitter which further splits it between TV's.

TV's are less prone to feel the effects of signal degradation. IIRC, each time you use a splitter the signal degrades by 5db or so.
 
I could try a mockup, I just have to buy some splitters first 😀

As it is now the cable modem is running about the same distance through a line from my outside cable box into one of the jacks in a bedroom here. I was going to try and piggyback everything on a new line I install (since I'm out of jacks in the room I need the computer), hence the funny diagram 🙂
