Say you had a freeview decoder and wanted to send that signal to a 2nd TV in another house across the road.....

Any ideas how you would do that wirelessly?

Analogue composite (yellow RCA) video would be sufficient.

Ah! I was going to suggest just using the web interface of your Vu+ Duo, but IIRC, you don't have broadband at home.

Obvious 1st approximation is a video sender, but you may need to site the antennae in line of sight to get the range you need, or otherwise boost the transmitted signal.

Next way is to record what is needed, copy it onto a USB stick, and use a catapult to transmit it wirelessly.

Does this mean you can view TV from any computer by just looking back to your Vu+ Duo unit via the internet? Man that's pretty cool.

Yup - you can search the EPG, set and review timers, watch whatever is being decoded in real time, change channels, play back recordings, etc. A couple of prerequisites though. You need to have a static IP address (or use a dynamic IP forwarding service), you need to forward incoming traffic on whatever port you decide to use through your router to the Vu+ on port 80, and you need to turn on the web interface via a menu.

Any reason for not just instal another Freeview decoder (+ dish) in the 2nd house,

It may prove to be a cheaper and more robust solution than putting together a wireless video sender solution.??

How many web interface sessions can be viewed simultaneously?

Yeah but it may be a read between the lines sort of thing.

Maybe we could just say it's a rental and they don't want to install any cabling.

Good question!
I don't know the answer, sorry.

You could head over to http://www.world-of-satellite.com/forumdisplay.php?11-VU-Duo and ask there, or to the openPLi support site.

5.8GHz sender and some waterproof boxes to get them up high. Thats assuming it really is freeview or sky or something thats already public. If you are wanting to stream something more private then its not suitable since it is in the clear analog.

Infact if it is just freeview etc, and you have a modulator in the box then a UHF antenna at each end and a signal amplifier will do the trick. I was doing that to get a feed out to my shed before I had a wire in place.

Hmm - good question - might have a play tonight to find out. There is one limit to be aware of, and that's the dual tuner limitation. It basically means that it can only decode 2x incoming satellite streams at a given time, although each stream can contain multiple channels. On very rare occasions (ie. once that I can remember) I've been refused when trying to record 2 channels and watch a 3rd, but in most cases this isn't a problem.

The other limitation I've noticed is that my WiFi can only support standard definition streaming, as it doesn't quite seem to have the bandwidth to do HD. HD streams fine over a wired connection though.

Our normal use case at home is that the VuDuo is recording stuff that will have ads in it while my wife watches a movie on Sky or is watching programmes recorded earlier. I'll be sitting at the computer half watching something else via a VNC session and catching up on emails and news groups.

Gotta LOVE that machine :-)
