Satellite Feeds for Dummies

What equipment would I need to receive and record a satellite feed?

Assuming I am given permission by the feed owner, what equipment would I need to have in order to lock onto a satellite feed, view the live feed, and possibly record the feed on a PVR type solution.

I know zip about satellite installations and am just trying to gauge if this would be easily doable. The feed would be from a news/entertainment organization from back in Canada..

Satellite dish, receiver, recording device*?

*VHS, DVD writer, DVR/PVR, or computer...

Read from here down for a basic over view.

This is assuming that this broadcast feed is not encrypted, if it is, you will need the appropriately configured receiver to decode it.

You're also going to need to know the elevation and directional settings for your dish, normally if you're paying for a subscription to a pay-to-view satellite provider their installer will do this for you, in this case you'll need to do it yourself.

This tool can help you work that out, it is likely that the tin can you're getting your feed from will be listed.

From the set-top box/receiver you can link up to a VCR, MiniDV with comp input, or any other recording medium which accepts the output that the receiver provides. There are a wide range of DVR's which have satellite receivers in them.

Do you mean old school satellite, like what they use to transmit network programs to different television stations? Or just receiving a particular channel on a cable-tv style satellite provider?

If it is the latter, you would probably need to obtain a receiver box that is authorized to receive that feed. Then a dish with the proper style of LNB (I think) and what direction in the sky to point it at. Usually that's a longitude degree by an azimuth (I think) degree. How high in the sky to point it. From there, the receiver box ought to have a signal meter that allows you to fine tune the antenna.(The LNB, if I have it correct, is the little thing at the end of the arm of the dish. The dish "catches" the signal and focuses it onto the LNB which is actually the antenna. I believe these have to be rotated for the proper angle.)

For the former, pretty much the same thing. Only the signal you are getting might be non-standard or scrambled/encrypted, and you'd need even more specialized equipment to get it.

Depending on the equipment for either scenario, the output would either be regular video that you could feed to a PVR or VCR or analog capture card, or you might be able to hook it to a digital tuner in a PC and grab it that way. Maybe even firewire.

Good luck! Sounds like an interesting project.

Just as an observation, I notice that you're in the UK, you might have some difficulties getting (open to be corrected here) North American satellites, as they'll either be below the horizon, or at such a low elevation that you'll have to be in a fairly open / high area in order to see the satellite. Of course, they may be using satellites which service other regions.

Thanks chrisbucks and gjc. To add a bit more, I'm trying to see if I can get the host broadcaster's feed for the Vancouver Olympics. I'm waiting to hear back from their local bureau here in the UK to see if they will be able to assist in this endeavour. I had a feeling that the North American satellites might be below the horizon for me but I'm hoping that they use another bird to get their feed from the home office and might be willing to give me access to it.

There are (or used to be, it's been a while since I've looked into it) magazines dedicated to this topic. If you know the satellite that's carrying the feed, you can look up its orbit, calculate the azimuth and declination from your position, and point your dish.

A satellite-reception system consists of, at minimum, four parts: My information is old so maybe things have changed, but I suspect the basics still hold.

For a good hobbyist system, you really want a dish that has motorized azimuth and declination, so you can aim it at different birds without going outside (or worse, up on the roof). But if you only care about one particular feed, this might not matter.

Also, if you're temporarily mounting a dish out in your yard, an aluminum patio umbrella pole stuck into a 5-gallon bucket full of concrete serves admirably as a mast and anchor, and can be purchased for less than $20 at Home Depot.

The suggesion of a 5-gal bucket full of concrete is applicable to small Ku/J band dishes only, not C-band...

This is almost useless, but most NA satellites are over the pacific. But I've been seeing (small) dishes pointed East lately, so there may be some over the Atlantic.

Beyond that, all I can say is that the video has to get to GB somehow, and I presume it is satellite. If the CA broadcasters can't or won't help you, there may be a local video club of some kind that might be able to help you out.

gjc - it's not always by satellite, quite frequently it is over dedicated fibre as well. Often a broadcast centre in one place will receive a broadcast via one medium and pass it on via another.

Eg, in the Auckland, NZ broadcast hub content will be received via satellite and then shared on (there are various contractual and reciprocal arrangements) via fibre to the states. Not sure how that works for the USA --> UK but it's probable that content is re-upped to satellites covering Europe after being received via fibre.
