It Depends. My understanding is that they don't normally capture "off air", but from the broadcast stream so it's the same as off air but without drop-outs caused by birds nesting on the aerial etc. And only some stuff is captured that way. > This would explain the truncations - especially pertinent to radio > programmes.

TV broadcasts contain enough metadata that they can tell what programme is correctly showing without having to look at the schedule. Radio broadcasts don't, so for radio they have to go by the schedule and pad it a bit at both ends. If the broadcast has gone way off schedule then you might get truncations. > I guess that if complaints are received that a programme has been > truncated then the staff replace the file with a complete one kept for > that purpose. Not kept for the purpose of replacing what's on iPlayer, but kept for archival and for repeating on Dave every week for the next 70 years :-) -- David Cantrell | Reality Engineer, Ministry of Information Please stop rolling your Jargon Dice and explain the problem you are having to me in plain English, using small words. -- John Hardin, in the Monastery _______________________________________________ get_iplayer mailing list [email protected] http://lists.infradead.org/mailman/listinfo/get_iplayer
