Question on how to get a video signal over my network

[MassiveEffect]

Ok here is my setup i have a wifi at my house and i use airmax antennas to get internet at my grandmothers house 7 miles away. What i want to do is to send my cable tv connection over that network i remember things like slingbox and things like that but i want to go one step farther i want to be able to transmit the signal the convert to back in to coxial form i also want to be able to change the channel on both sides any ideas?

To clarify, you want to transmit the entire signal that is typically carried on coaxial cable, including all the channels, so you can change between channels on the far side?

That might create a bandwidth issue.

so how much bandwidth do u think it would take

if so what i would like to do it transmit the video coming from the cable box then transmit the ir signal for the remote from the off site to the cable box

Ah I see, so you'd transmit one of the video output of the cable box, after it has decoded the signal? That would be lower amounts of data, after the cable box has chosen one channel among the many being carried over the coax cable.

But are you now describing the slingbox functionality, which could achieve that function?

For general info on the cable bandwidth, it's pretty huge but depends on analog/digital etc., see here: http://en.wikipedia.org/wiki/North_American_television_frequencies

You aren't going to be able to remote operate a cable box that way. Maybe you could kludge something to operate a wifi direct remote that way, but no chance of an IR remote (not without a lot of time on your hands and programming).

You might be able to do it with something like a Slingbox over wifi. I am not on the super up and up with sling boxes, but if you can pair them (which I think you can) over the network so that one slingbox is "slinging" the current channel from the cable box to the other slingbox, that'll work over the wifi connection and allow you to change channels to (I think). Then if you want it over coax, there are HDMI over coax converts, but keep in mind, this is going to be HDMI over the coax, not in a cable TV format over the coax, so you'll need another HDMI over coax coverter on the other end of the coax.

If what you are looking for is to basically send one channel (or worse, all of them) at a time over your wifi bridge, to your grandmother's house, covert it to coax video signals and plug it in to the back of a TV, its not going to work with any product out there.
