      Signal delay

      I'm on a communal system with Sky+HD and suffer from a considerable delay to my 'live' pictures. In comparison with radio broadcasts it's some 7 seconds late, and even lags behind the old cable and, I've just discovered, it's a full couple of seconds later than streaming video on betting sites. This really spoiled major events like the World Cup with people in other flats bellowing over goals or misses when the ball was still being knocked around mid-pitch! Should I expect such a delay on a communal setup? I don't have any picture quality issues at all.

      It's not a problem with your Sky digibox, but, as with all communal systems managed by housing associations/landlords etc, it's usually due to slow multiswitch/plexes installed by managing agents' satellite contractors. Maybe due to the age or quality of the setup. Not much you can do about it other than to have a word with whoever manages the system.

      The communal systems do nothing whatsoever to delay any satellite signals. Its purely down to the video compression processing time (H.264 for HD) and to a lesser extent the satellite delay (23,500 miles out and 23,500 miles back). Its the same for all Sky HD viewers.
      There is no p in Thomson.

      I think the guy downstairs has his own dish, so probably a combination of that and maybe he's not HD....or just the latter? The communal is new system anyway.

      If he is watching via a dish then he's watching SD. SD is MPEG2 and is encoded/decoded far easier than H.264, and therefore doesnt take as long to process.

      In increasing order of time lag you will find
      Analogue terrestrial
      Digital terrestrial Freeview SD
      Freeview HD
      SD satellite
      HD satellite

      Depending on the receivers Freeview HD and SD satellite may swap round.
