Yep - it's more important for us with our SD multicast system. We have a single 24Mbs mux carrying BBC One, BBC Two, BBC Three/CBBC, BBC Four/CBeebies, etc. all of which carry audio description, along with BBC News, BBC Parliament and a BBC Interactive video stream (which itself has multiple audio feeds for sporting events). Saving 128-192kbps per channel when you are broadcasting lots of channels can mount up? I guess the BBC are saving 768kbps potentially by using receiver mix?
I can imagine some markets wanting to broadcast, say, three to five different languages at once. Right now, the DD5.1 is only in English.
(Sneals: How many languages do they do for the "Eurovision Song Contest"?)
Ah - Eurovision. Very simple. One main programme audio - these days available in 5.1 and 2.0.
The presenters/hosts in-vision speak a mix of English (mainly), French (for some elements - particularly repeating the scores) and their own language.
In addition there are out-of-vision commentators from most of the broadcasters on-site, who separately add commentary in their own language. The hosts do not appear between every performance, but instead a "post card" or similar 30"-1'00" film (or in-arena graphic sequence) is played, and the commentators have a chance to discuss the next/previous song.
The hosts appear at certain points in the performance, where some countries will take ad-breaks. Because not all broadcasters - like the BBC in the UK, NRK in Norway, SVT in Sden etc. have commercials - the show has to work without breaks as well as with them...
So in the UK we hear Graham Norton (our commentator) out-of-vision speaking English, and the hosts of the show in-vision speaking English, French and their own language. If you are watching in Sweden for instance, then you'll get Swedish out-of-vision commentary instead of Graham.
Apols this is very off topic... But Eurovision usually is. It's an amazing show - as you can imagine any competition with 49 countries competing for a single "best song" prize is. It's been going for more than 50 years now.
