'[EE:] Cable TV over fiber?'

Anybody know of some conversion device to put regular cable TV over fiber optic?

A friend of mine has a couple buildings separated ~1/4 mile, they want to connect cable TV to a set in the lunchroom / lounge. With tearing up the parking lot and burying hardline it's going to be like $5,000 to run cable TV to the second building, but there already exists a multistrand fiber bundle between buildings (gigabit Ethernet plus several uncommitted 'backup' strands).

At the moment it looks like mini dish might be a better choice. At ~$50 per month for the dish it'd take ~8 years for the cable to pay off. Doesn't seem very practical, but maybe someone has a better idea?

blackbox makes stuff to extend video+audio -
If all else fails maybe put the tuner in the old building and send one
video+audio feed?

There are devices I know of that convert L-band signals from a satellite
LNB (950-1250MHz) to fiber and back again. I don't know what the frequency
domain of cable TV is, but maybe there is something like this for CATV?
Check with http://www.dawnfiber.com - you might want to just call them.

If you have gigabit Ethernet, why not try a SlingBox system?

Something like $200, would allow the cable TV signal to stream across
the network to the second building.  You'd have to watch on a PC, but
you could always connect that PC up to a television (most video cards,
laptops, etc., have S-VIDEO out these days).

I think you'd be limited to one television, because the SlingBox can
only have one client connected at a time, but after that initial
setup, it'd be free indefinitely.

Don't quote me on this, but:

I think you ccan use a Windows Media  Center PC with a TV-tuner card in it
at one end to encode the video and audio and place it on the IP network, and
then either an XBOX360 or Windows Media Extender at the other end to:

1) Decode the stream.
2) Send it to a TV
3) Provide a remote control interface to the PC running Windows Media
Center.

All of this can be done over the existing Gigabit TCP/IP backbone, requiring
no devices to interface with the fiber links.

If you have Linux experience, you could go with a MythTV PVR.  My PVR
cost about $1000 CDN to build, although that was a year ago, and with
a dual layer DVD burner.

The backend with the capture card(s) and hard drive(s) would live in
the main building, and the frontend would go in the second building.

You can watch live TV or recorded shows with this.

The backend would consist of a beige box, Hauppauge 150/250/350/500,
and a big hard drive.

The frontend can be anything with a supported TV out.  Most NVidia and
ATI cards are supported.

Another comment on this:

The Media Center PC at the first building does not have to be dedicated to
its function of streaming video to the other building. It can be used as a
normal PC, also.

Just what I was looking for, little on the pricey side though, about $2,000 for a set.

And the odd part - Dawnco is only about 30 miles from me and I'd never even heard of them.

Wireless transmitter (2.4GHz) and dish-like antennas on both buildings
(wok etc).

Works, till you have a cordless phone, microwave oven, or wifi.

If you can get a canadian video unit, IIRC they are on 1.2 GHZ, but of
course there are other users of that band in the US.

A computer in one building with a TV capture card, another computer in
the other building with a TV out port. The two computers connected with
fibre cards (or just use the existing gigabit network). The latest TV
capture cards allow for remote switching as well.

A lot (probably all) Dawnco equipment is rebranded. Maybe if you find
someone closer to the manufacturer it'd be cheaper? -- probably not.
Perhaps you could use one of the devices that sends/receives 1 video and
1 audio, combined with an ad-hoc scheme to change channels on the cable box?
It seems that the single channel devices are cheaper than the block
converter to convert the whole CATV spectrum.
It also seems that if you were going to do that you might want the
myth-tv computer solutions people are talking about.

Another idea:
Find a used professional microwave link used by virtually all radio and
TV broadcasters as a STL (studio-transmitter link).

I figured the wideband solution would be common in the OEM Cableco HFC
arena. Thats actually cheaper than I expected.
Sneaky to hide the expensive transmitter on on second page...
