Converting incoming Sat signal to IP then streaming...

villait

Ok so i have been working on this for a while and now have decided i need more brain power!

I am looking to 'catching' the signal directly from the LNB or switch in signal format, not video. Then converting this to a stream to stream over the net and then catch it and convert back!

Many people will come back and say ahh use the Slingbox, its great! yes i agree but this simply sends the video not the signal - so does not solve the concept.

In practice it will work like this - Dish set up in the Uk receiving - for arguments sake - Sky. Signal is 'caught' sent over the internet to a in IP format, this is then somehow converted back to the original signal via a gizmo and then a cable from the gizmo to a sky receiver.

The concept is aimed to deliver satellite signal to places where you cannot fit dishes but have a good internet connection, for example high rise flats.

i have simply used Sky as an example, it is the signal i am concerned about not the Tv content.

Hopefully this makes some sense and is not the ramblings of a mad IT installer!!!!

Any ideas!?

Cheers

Welcome to the Forum.
I can see advantages of what you are trying to do. Especially as the signal would still be encrypted where applicable as you stream it so I would have thought there would be no problems with uncle Rupert´s Lawyers.

Even if you get no joy on this forum keep us informed how you get on.

Good luck

The bandwidth required for such a system would be immense, in the region of 1Ghz for just one H/L V/H combination. It can be done by a direct fibre optic link, but via the internet, I don't think so. Even to get a good picture on a Slingbox is difficult enough practically, let alone a whole IF.

Welcome villait,
Nice idea, and the makings of an interesting thread. (putting my nerdy glasses on)

I'm sure it will become a possibility in the not so distant future (if it doesn't already exist).

One of the main problems would be with upstream data rates. A sling box or similar will only be uploading the required video and audio data.

My understanding is that if you want to upload a raw signal you are talking a lot of data. Any particular frequency an LNB is tuned to will be carrying enough data for multiple video/audio streams so, I would suspect that you would have an ammount of data that even the fastest internet connections (in this part of the world) would struggle to download quickly enough, let alone to think of uploading it.

I'm no sat signal expert, so if one of the more knowledgeable sat signal experts chimed in with some figures on data rates available on a sample transponder, that would be great.

The other thing would be that you would have to have exclusive access to and LNB, because it can only be tuned to one frequency at any given time.

If you were thinking of providing this as a service, you would need to have an LNB per frequency, per satellite along with servers and client side software to handle it all.

As trigger said. Let us know how you get on if you dont find a solution here.

PS: My comments are only to highlight the technical problems to see if anyone can think of a way around them, not to say its impossible.

EDIT:

Robbo got in ahead of me with the main problem. I should not wander off to make a cup of tea while posting.

hm... why need to stream all bandwidth at same time? targeting multi-tv audience?

You probably should look into the technology of IPTV or TV over IP and how this is done.
In your example you typed:

and then a cable from the gizmo to a sky receiver

Surely you would need another type of receiver, certainly not a satellite receiver.

Maybe this USD 22,995 Niagara Pro II from Viewcast can do the job

It's a good idea. But only if we can afford this much bandwidth. It's leagal and can be saw any channel that's not available in our region. And can be use CS for encrypted channels.
