"cable tv split off of cable internet line?"

Here's the deal: I'm subscribed to both cable tv & internet. The main line going to my house is split right outside of my house. The internet line runs along & up the outside of my house, then directly into my study which is upstairs. The TV line goes into the basement, where it's 4-way split to all the TVs on the lower two levels.

My problem: I now want to put a TV in my study, but don't have a cable TV line running into it, and to put a split from the existing TV line in the basement, would be a pain.

My Question: Can I split the internet line, and use it also for TV? I was told I could but would need a filter to block internet data from flowing into the TV. And I'm guessing since I have digital cable, I would need to get another cable box from the cable company.

Am I missing anything?
Also how hard is it to splice and add the BNG connectors?

Thanks for any help and positive comments!

Splitting- i split the line in my bedroom from the wall to tv and computer works 100% fine no srawbcks to doing this my tv here is cable ready

You should be able to do it with a low dB splitter, but be warned, it's probably against your ISP's terms of service and more than likely would be considered stealing cable.

You shouldn't split the cable going to your modem more then once. The more splitters you have the slower your connection speed (And it could be very dramatic i.e. Possibly No connection after adding even one split).
As far as data flow goes. You can do tv or internet on all your lines.

Hey,
I got cable internet a month ago and I asked the cable guy to hook it up to my tv too (i wasn't paying for cable tv). He agreed and split the cable line, one going to the computer and one going to a tv (no cable box). He didn't have enought time to bury the cable line and said he or some other cable guy would bury the line later. When I tried out both the cable internet and cable tv, both were working great. However, when the line was buried and I returned home from school the cable tv reception was real bad and I could only get BRAVO, FOX (on cable),ABC-FAMILY, MSNBC, CSPAN, and extremely blurry images of cartoon network and discovery channel. I couldn't find BET, ESPN, TNT, MTV, and many other channels. I tried hooking the cable line to the computer up to the tv and the reception is still bad. Yet the cable internet works fine. Why is that and how can I fix it? (I really want to watch the NBA playoffs)

Too many splitters can disrupt service. As well as quality/age of coax cable.

Rather than physically hook another TV to line, get a wireless transmitter. The transmitter I bought (by Zenith, carried at Lowe's) has both coax and audio/video jacks. It also comes with a universal remote and infrared re-transmitter, so you can have cable box in one room, and change channels from another room. The range on this gadget is pretty good, at least 50 feet through walls (cement block & aluminum siding too!)

I ran the coax to my TV and use the other jacks to feed the cable music channels to my stereo.

But I could hook up an extra TV, instead (as long as it had proper input jacks on the back). This would avoid the extra fees of another cable jack & extra box.

The snafu would be that there's still only one cable box. You can't watch a different channel on each TV.

I have a similar question i have cable tv can i split the cable and hook it to my computer for internet access?

And if so what would i need?

Thanks
