Does that mean that the news organisations can theoretically steal each others feeds just by pointing their dishes in the right direction?


It depends.

These days almost all uplinks/downlinks use digital compression - and this allows digital encryption. Some distribution links(particularly those used for sports) will use encryption. Others won't.

Many news links use no encryption - so if your dish is pointed at the right satellite, your receiver tuned to the right frequency, and in some cases you know the digital IDs of the video and audio streams (and in some cases you have a receiver capable of coping with 4:2:2 not 4:2:0 video) you can watch if you are in the footprint of the satellite.

Or is there any sort of encryption or password protection? Sort of answering my own question, I guess, I remember CNN getting annoyed when Fox stole their feed of the Columbia disaster - presumably this is how it was stolen?


Suspect so...

Most broadcasters are grown up enough to differentiate between "being able to receive" and "having the right to re-transmit"... Just because you can access a signal doesn't mean you have the right to broadcast it as your own...

After all - huge numbers of non-BBC satellite broadcasts are downlinked by dishes at BBC TV Centre for non-BBC broadcast. (ITV often use BBC TV Centre dishes for their sports downlinks)


you mean like a motorised receiver with a PC Sat card which is for the moment the cheapest way to get 4:2:2, the PC needs to be powerful too to cope with 4:2:2

Doesn't even require that. Many feeds are on time shared unilateral EBU etc links.
Just a case of not recording, or at least Tx'ing the bits that aren't yours.


Eurovision News is another example I think. RTÉ use them to uplink some of their reports. They've gotten caught out a few times though, these examples show the reports abruptly cutting to a schedule for other broadcasters:
Scroll to 7:12
Scroll to 13:19

EDIT: The clips are really unstable on my PC, I can find other links and post those if they don't work out for others

If you're a broadcaster a PC receiver isn't that good a solution - as getting broadcast video OUT of a PC is not always that straightforward. (VGA is NOT a broadcast format)

Cheaper than a PC+DVB-S card is usually one of the earlier MPEG2 HD receivers that also had 4:2:2 capabilities - that were sold for Euro1080.

That's just poor editing. The pictures from the Middle East would have been sent on the EBU feed to all broadcasters subscribed to use them at some point throughout the day or night. RTE downlink and record the "rushes" and edit their own news package. The graphic just tells those monitoring the feed what's coming up, when and sometimes who can / can't use the feed.

For example, APTN carry the Earth TV live feed every 5 minutes to the hour that Sky Travel show, anyone can opt in and view / record or even re-broadcast, but only those licensed or subscribed to it will do so, the rest just sit and watch!

Not quite, the AP GVW (Global Video Wire) is encrypted and only Earth TV clients get Earth TV. The same is true of their sports, entertainments and science (Horizons') bulletins

Where I work we don't need (or pay for) Earth TV so we get a static picture for 5 minutes while its on.

Eurovision News is a news wire service that distributes pictures to all their subscribers. These won't necessarily be RTE pictures (unless of course the story concerned happened in Ireland) and any Eurovision subscriber can use them.

If RTE wanted to get their own pictures back from another part of Europe they might well use EBU circuits for their feed. Both members and non-members can use the EBU's facilities, although of course non-members pay a lot more

We never subscribed to the Earth TV feed but it comes through unencrypted - and that was only News / Ents and SNTV that was ever used. It's just the same as on the Sky Travel feed but with extra promo stuff at the front and back of it leading up to the news feeds.

Yeah I know it well, but with us it normally shuts off at xx:55 and starts again at xx:00. Perhaps you're just lucky, or work at the BBC. The BBC's feed of AP GVW (and Reuters) does contain everything, but then they are a big client and they do use Earth TV on BBC World

Wasn't the BBC - t'was TV3 in Ireland, so it wasn't really a big client. Perhaps it's just a slip up and no ones really caught onto it yet, but then again as already mentioned, your not gonna use something unless your paying for it so common sense should prevail and you wouldn't re-broadcast the feed without permission

Let’s hope and pray these reports are false. Only God knows what his family and friends must be going through right now.
