In general, the question for those who understand television technologies is that we have 11 time zones through the country if I am not mistaken (or have passed), respectively, for example, the new year is also found 11 times (in a rough formulation), and Vladivostok meets a few hours before Moscow — like Is the President's congratulation technically organized so that everyone has to be on time? Somehow, I think you will understand what it is about.
The question is certainly not yet relevant, just today one comrade stated that he was watching the match broadcast by satellite an hour earlier than I was in the box - and the “live broadcast” icon stood on the box and something was remembered - how is that possible?
UPD: To be closer to the IT topic - how is everything mentioned above (for example, congratulations on the new year) being organized during Internet broadcasting (of the same federal channels)? Focus with local stations and orbits of satellites as I understand it with this option is not a ride?
