can TV be run off of cable internet connection?

[Warp6]

Just curious, not that I'd actually do it
I currently have Direct TV (sattellite) but when the clouds roll in during a big storm I lose connection. Was wondering if I could tap into my RoadRunner internet connection for brief TV use. If so, will I need any special connectors (for frequency change or whatever)

Does roadrunner do cable TV also? My provider does so it uses the same line. Internet runs off of frequencies, different from what TV uses on the line. Therefore both can use a single line and not interfere with eachother. I guess there is only one way to find out though if yours will work.

yes just run a tee off your cable line and some coax cable to your TV. i did this and picked up about 10 extra channels...AT THE REAR WHEELS!!!

Careful splitting the signal more than it can tolerate. Envision your cable internet/tv signal as nothing more than a hose with water containing a certain PSI. When you split it what happens?... PSI divides in half, which is basically what you're doing with your cable signal. With that said, your cable modem requires a much higher signal strength than your TV in order to function properly. This all depends on how strong your signal is coming into your home from the pole and that depends on many factors and isn't necessarily equal house to house. If you're going to be making your own splices make sure you know what you're doing. Anyone can install a cable fitting on an RG-58 or RG-6 line, but not everyone can cut one properly and that can affect signal strength immensely. By the way, I used to install, service, dispatch and operate the mainframe for Comcast many moons ago.

Good luck,

I tried it and got nothing but snow. Unplugged from modem and went directly to TV

TT/A1233-
you bring up a good point- kinda hits home here-

my grandma bought this house in 1968 and back then i dont believe there was cable-
when cable was introduced she got it, and we still have the same lines from 1971?? leading into the house from the pole, and into the basement-
ive been fighting with roadrunner because the visual quality sucks-
BTW i have digital roadrunner for the computer and the tvs all on one line
back in the day they used 2 lines for A OR B and now we only use one in the house which provides the digi for the internet and cable for the roadrunner box-

anyway- ive complained about the service and had about 4 guys out here to fix the problem-
i never knew they made amplifiers for the cable system!
i now have better quality picture and not as much static on some of the basic channels-
just a lil FYI so you can run wires older than me and still get good reception and split the 2 wires into 5 more sets of 2

Give Kevins little brother Randy a call on this, he used to work for Time Warner.

I also know you have to have cable service first before you tap in the line, I think there is a filter on the line from the junction where ever it comes in from the box by the road. I really don't know about this for sure.... , I think Randy still has some special tools for these things, but then again, I don't know about all this.......

By the way, I should be getting the Buick back this week.

You can run rr and have a TV on at the same time. If I understand correctly its a dB level that rr relies on. Maintain the dB level and you can have both.. May wanna ask Randy..??

At least with Cox, the cablemodem and digital channels are below the channel 2 frequency. They put a filter on at the street to block analog 2 and up from coming in, so you don't get free basic cable too. (I asked the serviceman about this, and have tried it). If you had some "illegal" digital box, in theory you could get all the channels. I'm not promoting this, just making a statement.
